The 12-30-30 walking workout is one of the most buzz-worthy exercise methods on social media. Created by Lauren Giraldo in 2019, the simple treadmill routine, which involves walking for 30 minutes at an incline of 12 percent and speed of 3 miles per hour, helped the influencer lose 30 pounds. In four years, it has helped endless people lose massive amounts of weight. How can you lose the most weight and burn fat fast and efficiently with the walking workout? Here are key tips from fitness experts, weight loss warriors, and nutritionists.

Start with Less Incline

Consider 12-3-30 a goal. However, if you are just starting out, you don’t have to hit the numbers. “Start off slowly and build up your incline,” recommends fat loss coach Baylee in a TikTok video. “You will still get benefits of your workout if you are on a 3 incline or a 6 incline, so long as it’s challenging to you.”

Start with Less Speed

“Also, build up your speed,” Baylee suggests. “Once it gets easy, increase the speed so that you can continue to progress and continue to challenge yourself.”

Don’t Hold the Handrails

Laci Renee, a fitness influencer with 218,3000 followers, offers up a serious tip in a viral video with over 1 million views. “Don’t hold the handrails,” she says. Why? You are undoing the work needed to walk on an incline.

Also, Don’t Lean Back

Also, don’t “lean back,” she says about the “one easy and common form correction to get the most out of this exercise.”

Lean Forward Slightly Hinging on Your Hip

Julie, a fitness trainer, offers the following tip. “Lean forward slightly hinging on your hip,” she says about the proper form in a video.

Don’t Do It Before Lifting

If your goal is to build lean muscle — or tone – “don’t do it before lifting,” Julie warns. “Conserve your energy and lift first.”

Stand Up Tall

Also, Julie reminds to “stand up tall,” as you are losing “core engagement and not bringing your heart rate up,” by slouching.

Do Intervals

One fitness influencer, Deanna, AKA the “curvy millennial” revealed in a TikTok that she created intervals with the 12-3-30. “I do incline 12 with speed 3 for 10 minutes, take a 5 minute break to incline 2 with speed 2.5. I do this 3 times.”

Squeeze Your Core

Taylor Donoghue revealed her hack for the 12-30-30 in a video. “Squeezing your core while walking 12/3/30 on the treadmill always helps me tighten and firm my stomach while also promoting good posture,” she says.

Watch a Netflix Show

In order to make the time pass faster, try and watch a show instead of counting down the minutes. “My trick is playing a Netflix series as you go. Don’t watch the clock,” suggests Libb Stokes.

Don’t Look at the Clock Until You Feel Tired

“Don’t look at the clock until you feel tired,” suggests Kaitlyn Anderson. “If you are just sitting there looking at the clock the whole time until you reach a certain number, of course, you are going to feel tired when that time approaches. But if you don’t look at the clock and you just keep going until you actually feel ready to quit, then you are going to be able to go so much longer.”

Read a Book

Selena Torres recommends reading while walking. “Do 12,3,30 and read on the treadmill. You get your steps in, and the time goes by 3 times faster,” she claims.

Pair with Strength Training

Tonal Coach Kendall “Woody” Wood suggests pairing 12-3-30 with strength training for maximum fat loss. “12-3-30 is simply LISS (low-intensity steady state) cardio, which helps increase blood flow, relieve tension, and mobilize the joints, while strength training improves your muscle mass, connective tissue health, and flexibility to prevent injury during exercise – making both super beneficial in your workout regime!” Woody points out. Try doing at least two strength training workouts per week, incorporating functional movements such as squats, lunges, and hinges.

Take Rest Days

Make sure to take rest days, says Woody. “Incorporate 1 to 2 rest days per week to allow your body to recover and adapt to the training stimuli. This prevents overtraining, which can hinder fat loss progress,” she says.

Don’t Forget to Stretch

Woody adds that you need to prioritize recovery and mobility. “Don't overlook the importance of recovery and mobility work. Incorporate stretching, foam rolling, and mobility exercises to maintain joint health, reduce injury risk, and enhance overall performance,” she says.

Drink Fluids

Body Network’s Resident RDN, The Diet Diva, Tara Collingwood, MS, RDN, CSSD, LD/N, ACSM-CPT, a Board Certified Sports Dietitian, co-author of the Flat Belly Cookbook for Dummies, reminds that you should drink plenty of fluid, “mostly water, throughout the day to make up for what you are losing in sweat as well as what you need for your normal day,” she says.

Make Sure You Don’t Eat Back Your Calories

“Don’t eat back the calories you are burning on the treadmill,” says Collingwood. “Use the workout to help contribute to a calorie deficit for the day.”

Fuel Your Body with Carbs and Protein Post Workout

Collingwood also suggests fueling up post workout. “Make sure you recover your body by getting fluid and carbs within 30 to 60 minutes after your workout and get some protein within 2 hours after finishing,” she says.

Make Sure You Are Consuming Enough Fiber

“Get at least 25-30 grams of fiber from fruits, veggies, and whole grains to keep you feeling more satisfied and keep your digestive tract moving,” says Collingwood.

Get 7 to 9 Hours of Sleep

Finally, make sure your body is getting the rest it needs to recover. “Get 7 to 9 hours of quality sleep so your body can recover properly and release the hormones you need to repair and build the muscles you used,” Collingwood says.

Hold Weights or Wear Ankle Weights

Samantha Harte, Doctor of Physical Therapy and founder of StrongHarte Fitness, recommends adding some extra resistance. “Hold light free weights or wear ankle weights while you’re on the treadmill,” she suggests.

💪🔥Body Booster: Begin your workout with a low incline and gradually increase it as you progress. Remember, any incline that challenges you will provide benefits, whether it's a 3 or a 6.

Do you want to lose weight fast without running? Mahtab Ekay is a fat loss coach and social media influencer who lost 20 pounds in 3 months. In a recent Instagram post, she revealed her hack for losing weight fast, which doesn’t involve pounding the pavement. “The cardio trick I used to lose 20 pounds in 3 months without running,” she writes across the Instagram Reel.

You Need to Be in a Calorie Deficit

“I know you want to hear about some secret workout routine. But the truth is, there’s NO special cardio that will ‘cause’ weight loss,” she writes in the post. “If you’re serious about losing weight, start with the one thing that’s key to success: being in a calorie deficit.”

In Fact, 80 Percent of Weight Loss Comes From Nutrition, She Says

Mahtab maintains that diet is the leading factor in weight loss success. “80% of weight loss comes from nutrition. The best thing you can do for the other 20%, in addition to strength training, is walking,” she explains.

Walking Burns 100 Calories in 30 Minutes

“Walking can burn approximately 100 calories in 30 minutes at a moderate pace. By walking consistently, these calories add up over time, contributing to your overall calorie deficit,” she points out. “And that’s exactly what helped me lose 20 pounds in less than three months.”

She recommends keeping track of your steps. “First, check your average daily steps in your phone’s health app. This is your starting point,” she says.

Increase Your Weekly Steps

Then, progress toward a step goal. “Gradually increase your average weekly steps. If you’re currently taking 5,000 steps daily, aim to add 1,000 steps in the next week,” she says.

And, continue. “Keep increasing by 1,000 steps each week until you consistently hit 8,000-12,000 steps per day,” she recommends.

How to Increase Your Daily Steps

She also offers “some easy, quick ways to increase your daily steps.”

  • Take the Stairs: Skip the elevator or escalator for an easy way to add more steps.
  • Park Further Away: Choose a parking spot farther from your destination to get extra steps in.
  • Walk During Breaks: Use your breaks to take short walks and boost your step count.
  • Walk and Talk: Pace around while talking on the phone to stay active.
  • Use the Restroom on Another Floor: Opt for a restroom on a different floor for added steps.
  • Set a Step Goal Reminder: Use a fitness tracker or app to remind you to move.
  • Walk During TV Time: Walk in place or do laps during your favorite shows.
  • Take a Post-Meal Walk: Walk around the neighborhood after meals to aid digestion and add steps.
  • Use a Standing Desk: Stand and move more frequently throughout the day.

Other Benefits of Cardio

“Cardio has many benefits for heart health, overall fitness, and mental well-being. If you enjoy it or are doing it for those reasons, go for it! You just don’t need it to lose your first 10-20lbs,” she concludes.

There Are Lots of Benefits to Walking

Going for a daily walk can be a game changer for your overall health. One study published in JAMA Internal Medicine found that walking at a brisk pace for about 30 minutes a day led to a reduced risk of heart disease, cancer, dementia and death, compared with walking a similar number of steps but at a slower pace.

Science Has Found a Link Between 10,000 Steps a Day and Weight Loss

Research supports walking for weight loss. According to a 2018 study published in the journal Obesity walking 10,000 steps a day results in weight loss and weight management. Other studies published by the Journal of American Medical Association (JAMA) in JAMA Neurology and in JAMA Internal Medicine also linked walking 10,000 steps a day to less dementia and less cardiovascular disease overall, with less heart disease, less heart failure and fewer strokes.

When it comes to losing body fat, most people think they need to run for hours or spend endless time at the gym. But groundbreaking research has uncovered something simpler: there's a specific walking speed that maximizes fat burning, and it's changing how we think about weight loss.

Meet Michaela (Dr. Miche), PhD, a research scientist who analyzes cutting-edge studies on weight loss, nutrition, and fitness. "When confronted with these kinds of debates, I go straight to the science and try to get the best answer based on the highest quality research," she explains. Her recent analysis of walking studies has revealed fascinating insights about how this simple activity could be the key to sustainable fat loss.

Why Walking Beats Running for Fat Loss

In a groundbreaking 20-week study comparing different exercises, walking proved superior for fat loss. "The walking group lost three body fat percentage points, while running and biking groups only lost 1.2 points," Dr. Miche reports in her post. This occurred despite all groups exercising for the same duration—30 minutes, three times weekly.

The Science Behind Fat-Burning Speeds

Why does walking outperform more intense exercises? "As the intensity is lower in an exercise, you actually burn more fat compared to carbs," Dr. Miche explains. "Whereas when you do a very high intensity exercise, you burn more carbs compared to fat." This makes walking particularly effective for fat loss, despite—or rather, because of—its lower intensity.

The Perfect Speed for Maximum Fat Burn

The research uncovered specific speeds that optimize fat burning. "For men, the sweet spot is typically walking at 3.4 miles per hour, while women reach optimal fat burning at around 3 miles per hour," Dr. Miche reveals. This pace aligns with what scientists found to be the ideal heart rate for fat oxidation—about 60% of your maximum heart rate.

Proof It Works: The Numbers Don't Lie

A comprehensive meta-analysis of over 1,100 participants confirmed walking's effectiveness. "People who walked just 40 minutes, four times weekly for 35 weeks, lost two pounds and decreased their body fat by one percentage point—without making any dietary changes," Dr. Miche explains. Even more impressive, she notes that while walkers lost weight, non-walkers gained a few pounds, creating a net difference of about five pounds between groups.

Why Body Fat Matters More Than Weight

Dr. Miche emphasizes an important distinction: "When most people say they want to lose weight, what they really mean is that they want to lose fat and lower their body fat percentage." She explains that "the aesthetic benefits and health benefits of weight loss pretty much all come from lowering your body fat percentage," noting how many people "end up looking a lot better and getting a lot healthier while staying at the same weight because they lose fat and gain muscle."

The Ideal Walking Schedule for Beginners

Based on the research, Dr. Miche recommends starting with the proven formula: "The meta-analysis found that on average these studies had people walk four times a week for 40 minutes per session." This moderate commitment led to significant results while remaining achievable for most people.

Hidden Benefits Beyond Fat Loss

Walking at the optimal speed doesn't just target fat—it transforms your health. "Just adding 40 minutes of walking four times a week lowered blood pressure by one to 1.5 points for both systolic and diastolic blood pressure," Dr. Miche notes. Additionally, "people increase their fitness substantially, raised VO2 max by three, which is a measure of cardiovascular fitness."

How Walking Prevents Age-Related Weight Gain

One of walking's hidden benefits is its role in preventing natural weight gain. "Not only did adding walking to people's routines prevent the weight gain that most people have happen to them over time as they age," Dr. Miche points out, "but adding walking also caused weight loss on top of that prevention of weight gain."

Your 7-Day Walking Challenge

Ready to start? Dr. Miche recommends focusing on hitting the optimal speed rather than distance: "It's not only useful for weight loss but also because it's just amazing for your health and it's nice to get outside." Start with 40-minute sessions at your target speed (3.4 mph for men, 3.0 mph for women), aiming for four sessions in your first week.

The science is clear: walking at the right speed is a powerful tool for fat loss and overall health. Whether you're starting a new fitness journey or looking to optimize your current routine, adjusting your walking speed could be the simple, effective strategy you've been searching for. The best part? You can start today, right now, with nothing more than a pair of comfortable shoes and a focus on maintaining that perfect, fat-burning pace.

Unless you live under a rock, you are well aware that walking is one of the best workouts for losing weight and maintaining your overall health. However, getting the recommended steps to lose weight and burn fat can be difficult, especially if you have a job. Kelsey Rose is a fitness trainer and social media influencer with hundreds of thousands of followers. In a new post, she issues a “PSA” about walking, explaining that “the #1 tool for FAT LOSS for women is literally free!!” According to Kelsey, if you have a “sedentary” job where you only get in 2,500 steps a day, adding a 30-minute walk before and after work will help you burn an additional 260 calories a day, which could help you lose 10 to 15 pounds in 6 months if paired with an 80/20 diet. “10 other hot tips for hitting those daily steps when working a 9-5,” she writes.

1. Turn Your Morning Routine into Movement

Per Kelsey, the first thing you should do is incorporate walking into your morning routine. “Instead of scrolling or lingering over coffee, use 10-15 minutes in the morning to pace around your home, stretch, or go for a quick walk. I wake up in the morning and go outside first thing!” she writes.

2. Take Active Commutes

Turn your commute into a workout, Kelsey encourages. “If possible, walk or bike to work. If you drive, park farther away or get off public transport a stop early to squeeze in extra steps,” she says.

3. Walk During Meetings

Try and get your steps in while you work by multitasking, Kelsey suggests. “Turn phone calls or virtual meetings into walking meetings. Pop in your headphones and take your call while pacing or walking outside,” she says.

4. Use the Stairs

Turn your office stairwell into a StairMaster, suggests the trainer. “Ditch the elevator! Take the stairs whenever you can to sneak in extra movement,” she writes.

5. Set Hourly Step Goals

Set hourly goals instead of a daily goal to get your body moving. “Set a timer to remind yourself to get up every hour. Walk around the office or do a quick lap at home if you’re working remotely,” says Kelsey.

6. Take Your Lunch Break Outside

Use your lunch break as an opportunity to get fresh air plus exercise. “Go for a brisk walk after eating. It’s a great way to recharge while adding steps to your day,” she says.

7. Use a Smaller Water Bottle

While most experts recommend using large water bottles, a smaller one may help you stay more active. “A smaller bottle means more trips to refill it. Plus, staying hydrated keeps your energy up!” she writes.

8. Walk During Breaks

If you take breaks throughout the work day, use them as an opportunity to take mini walks. “Instead of scrolling on your phone, take a 5-10 minute stroll during your morning or afternoon breaks,” Kelsey writes.

9. Make Errands Active

Multitasking during errands can help you get even more activity in. “Walk to grab coffee, pick up lunch, or drop off documents. Even small tasks can help you rack up steps,” suggests Kelsey.

10. End Your Day with a Walk

Finally, use the end of the day as a time to reflect and get a workout in. “Wind down after work with a 20-30 minute evening walk. It’s a relaxing way to hit your step goals and clear your mind,” says Kelsey. And if you enjoyed this article, don't miss12-3-30 Walking Method: 20 Proven Tips to Lose Weight Faster.

We've consulted with our team of licensed nutritionists and dietitians to bring you informed recommendations for food products, health aids and nutritional goods to safely and successfully guide you toward making better diet and nutrition choices. We strive to only recommend products that adhere to our philosophy of eating better while still enjoying what you eat.

Struggling to find time for lengthy workouts? You’re not alone, and the good news is, you may not need hours in the gym to jumpstart your weight loss journey. According to certified clinical nutritionistAutumn Bates in her popular YouTube video, a strategic walking routine could be the game-changer you're looking for. Autumn's approach revolves around optimizing fat-burning through carefully timed walks that work with your body's natural rhythm throughout the day. Whether you're a morning person or find it easier to move during lunch breaks, Autumn's plan is designed for anyone who wants to maximize fat loss without sacrificing too much time or energy.

Walking, as Autumn explains, has the unique ability to tap into the body’s fat stores, especially during certain times of the day. Her three-part walking schedule will help you keep your metabolism revved up from the moment you wake up until you head to bed. Even better, you don’t need any special equipment—just your feet, a good pair of shoes, and some dedication. Joining Autumn’s expert advice is Body Network’s Yaa Boakye, Registered Dietitian Nutritionist (RDN), Licensed Dietitian Nutritionist (LDN), and Certified Personal Trainer (CPT), who provides additional insights into how walking can be tailored to meet your individual needs, ensuring both immediate results and long-term sustainability.

Ready to start walking your way to a healthier, leaner you? Let's dive into Autumn Bates' fat-melting walking routine and discover how just a few simple steps can make all the difference.

The Morning Walk: Capitalize on Your Body's Natural Fat-Burning State

In her video, Autumn emphasizes the importance of a morning walk: "In the morning, the body is in a naturally fasted state. This means that from overnight of not eating, the body is naturally going to be burning fat as fuel."

She recommends:

  • 15-30 minute walk first thing in the morning
  • Before coffee or breakfast
  • Preferably outdoors

"Walking outside is preferred if you are looking to maximize fat burning," Autumn explains. "Being outside, especially if you live by a park or an ocean or a lake or a river, helps to expose your body to something called negative ions. And this can naturally help to decrease the stress hormone cortisol."

The Science Behind Morning Walks

Body Network’s expert, Yaa Boakye, RDN, adds scientific context: "Research has found that both treadmill walking and brisk walking effectively reduce central obesity in men and women who are overweight or dealing with obesity. Women may burn more calories per step, while men may have a higher overall energy expenditure due to greater body mass."

Daytime Walks: Break Up Sedentary Periods

In her video, Autumn suggests incorporating short walks throughout your workday:

  • Get up every hour for 1-2 minutes
  • Walk around your house or office
  • Aim for about 2000 extra steps during an 8-hour work period

"The less often that we get up, even if it's just getting up for one or two minutes an hour, the less we're contracting our muscles and the less insulin sensitive we start to become," Autumn notes.

Lunchtime Bonus Walk

If possible, add a 15-minute walk after lunch. Autumn explains in her video, "When you're walking or when you're contracting your muscles, it helps to soak up excess glucose from the blood supply, making so you don't need to pump out as much insulin, which is that storing hormone."

Evening Walk: Enhance Sleep Quality for Better Fat Burning

Autumn recommends a short walk after dinner:

  • 5-15 minutes long
  • Preferably outdoors

"Walking can not only help with absorbing that excess glucose, it can also help to boost the quality of your sleep, which further helps to maximize fat burning," she states.

The Long-Term Benefits of Walking

Boakye emphasizes the sustainability of walking for weight loss: "Walking is not only effective for initial weight loss but also plays a crucial role in long-term weight maintenance. Research indicates that individuals who engage in regular walking are more likely to sustain their weight loss over time."

Maximizing Your Walking Routine

To enhance your walking routine, Boakye suggests:

  1. Incorporate interval walking
  2. Walk on an incline
  3. Add strength-building exercises
  4. Aim for 7,000 to 10,000 steps per day

Walking Really Can Help You to Lose Weight

By following this strategic walking schedule, you can harness your body's natural fat-burning potential throughout the day. Remember, consistency is key. As Boakye notes, "Walking is an incredibly effective and sustainable tool for weight loss. It burns calories, increases fat metabolism, and is easy to maintain long-term due to its low impact and accessibility."

So, you want to lose weight fast – without having to pay a personal trainer or sign up for a class? One of the most popular workouts for weight loss doesn’t require a gym membership or an expensive fitness pass. In fact, all you need is a treadmill and a pair of sneakers. The 12-3-30 workout has millions upon millions of views on TikTok for a reason – it works. Here is everything you need to know about the 12-3-30 treadmill workout.

Lauren Giraldo Created the 12-3-30 Workout

laurengiraldo2laurengiraldo/Instagram

When she was 24, Lauren Giraldo made the 12-3-30 treadmill workout go viral. It involves setting the treadmill to a 12% incline and walking at 3 miles per hour for 30 minutes. She first shared the treadmill routine in a 2019 YouTube video, uploading it to Instagram and TikTok in 2020, where it went viral. In the clips she claimed that it helped her lose 30 pounds.

"I used to be so intimidated by the gym, and it wasn't motivating," Giraldo explained in a 37-second TikTok video. "But now I go, I do this one thing, and I can feel good about myself."

She Calls It a “Game Changer”

“Game changer honestly. Have you tried my treadmill routine?” she captioned another post.

She Struggled to Run

laurengiraldo4laurengiraldo/Instagram

Giraldo explains that her struggle to run on the treadmill let her to seek an alternative. "I'm not a runner, and running on the treadmill was not working for me," she told TODAY.com. "I started playing around with the settings, and at the time, my gym's treadmill had 12 incline as the max. The three miles per hour felt right, like walking, and my grandma had always told me that 30 minutes of exercise a day was all you needed. That's how the combination started."

Most Fitness Experts Are On Board with the 12-3-30

While some viral workouts aren’t exactly endorsed by fitness experts, there is little controversy surrounding the 12-3-30. In fact, there is scientific evidence supporting it.

Walking on an incline burns more calories than walking fast or even running on a flat surface, which is why many experts suggest upping your incline. A 2013 study even found that walking on a 2 to 7 percent incline increased heart rate by almost 10 percent when compared with running on a flat surface.

“Walking is an excellent way to get started in exercise,” agrees Body Network’s Resident RDN, The Diet Diva, Tara Collingwood, MS, RDN, CSSD, LD/N, ACSM-CPT, a Board Certified Sports Dietitian and a co-author of the Flat Belly Cookbook for Dummies. If you don’t want to jog/run, elevating the incline on the treadmill is a great way to get your heart rate higher, she adds.

You Might Want to Start at a Lower Incline, She Says

“However, be careful with how much and how long you do the incline. Start with just a few degrees for a few minutes. Bring it back down for a few minutes and raise it again, repeating several times in interval style. I have seen people get injured by doing too much incline too quickly and not letting their body acclimate to it.”

The battle against belly fat after 40 can feel like an uphill struggle. Those changes in our waistline seem to happen overnight, leaving many of us wondering if this widening middle is simply our new reality. Tracy Campoli understands this frustration firsthand. At 49, this certified personal trainer, Pilates instructor, and health coach balances her professional expertise with the real-life challenges of being a mom in menopause. "It's really frustrating seeing these changes that can happen in our bodies as we get older," Tracy says, "but we don't have to accept all of them as just being 'that's just how it is'." Tracy discovered that 20-second workout intervals were key to her transformation. Read on to discover how her Tabata-style workouts and other practical strategies can help you reduce belly fat at any age.

The 20-Second Workout That Changed Everything

Forget endless crunches - they're not the answer to reducing belly fat. "What we want to do is implement the right kinds of workouts," Tracy advises. For women over 40, she discovered that Tabata and HIIT (High-Intensity Interval Training) workouts were the most effective approach for burning fat and building lean muscle.

"Tabata is really my favorite because you're doing 20 seconds of intense work and then you have a 10-second break built in," Tracy explains. This 20-second interval approach became her secret weapon. "What that's gonna help you to do is burn fat and increase your lean muscle mass - that's what's gonna help you see that slimming in your middle."

Focus on Strength

Strength training is equally important. Tracy emphasizes that your body itself provides resistance: "Your body is a source of weight and resistance." Whether through Pilates, resistance bands, light weights, or bodyweight exercises, incorporating strength work helps prevent the menopausal widening many women experience.

Why Her Old Workouts Weren't Working

"Back in the day, you know I grew up in the 80s myself, we were told if you want to have a slimmer middle, you got to do crunches all day long," Tracy shares. "That's not the case. By now we know that that is not true at all."

Instead of focusing solely on abdominal exercises, Tracy found that combining cardio intervals with strength training gave her the best results. In her fitness membership Total Body Transformation, she incorporates "strength training inside of the cardio workout so that you're getting basically more bang for your buck."

Chill Out To Slim Down

Your stress levels could be directly contributing to that stubborn belly fat. "Reducing your stress level is like a direct line to decreasing your waistline," Tracy explains. She points to that common experience of clothes feeling looser after vacation despite enjoying richer foods - that's your body responding positively to reduced stress levels.

The science is clear: stress elevates cortisol, which has a direct link to increased belly fat. "When we are stressed out, what happens? Our cortisol levels rise in an unhealthy manner, and so that is a direct link to our belly fat," Tracy says. She recommends simple stress-reduction techniques like nature walks, connecting with friends, practicing yoga, or even just taking three deep breaths. These small actions can make a significant difference in both your stress levels and your waistline.

Eat This, Not That

Proper nutrition becomes increasingly important as we age. "Especially if you're in your 40s, 50s, 60s and beyond, it's really important that we are fueling our bodies with nutrient-dense food," Tracy emphasizes.

For women over 40, adequate protein is essential for building lean muscle mass. "You want to be making sure especially over 40 that you have adequate protein. That protein is going to really help to create lean muscle mass," Tracy advises. She recommends a balanced approach with plenty of vegetables, fresh fruits, and proper hydration.

Rather than obsessing over individual food choices, she suggests taking a "bird's-eye view" of your daily nutrition. "A lot of women will come to me and say 'I had three cookies so I messed it all up'," Tracy shares, explaining that occasional indulgences won't derail your progress when your overall diet remains nutrient-dense.

Dress Smart, Look Slimmer

How you dress can significantly impact both how you look and how you feel about your body. "If you're wearing big floppy tents or just hiding, that's actually going to make you look worse," Tracy warns, acknowledging it seems counterintuitive.

On days when you're feeling less than your best, Tracy suggests putting more effort into your presentation, not less. "Those days when I feel like a troll... I feel like a completely different person when I actually brush my hair, put on some makeup, and dress in a way that makes me feel pretty," she shares. This outside-in approach can boost your confidence and actually make you appear slimmer.

You're Not Invisible After 40

Tracy is passionate about women of all ages feeling visible and valued. "One of my missions is that women of every age and every stage of life know that they are worthy of being seen," she says passionately. "You are not just doomed to being invisible after the age of 40, 50, or 60. Yes, you are still beautiful. Yes, you are still attractive. Yes, you are worthy of showing up in the world in the best way that you know how to be."

She encourages women to find styles that make them feel good about themselves, whether through online inspiration or fashion magazines.

My Ballet Trick That Works Every Time

Drawing from her lifelong ballet training, Tracy shares one final tip: lightly engaging your abdominal muscles throughout the day. "We're never letting our belly go; we're always lifting the belly up and in," Tracy explains, clarifying this isn't about uncomfortable "sucking in" but rather a gentle engagement of your deep abdominal muscles.

"This is not a size thing because I used to do this when I was pregnant and my belly was out to here," she notes. "This is about just lightly engaging the muscles, those deep muscles in your abdominals."
This simple practice improves posture, creates a longer, leaner appearance, and can even help prevent back pain, especially important as we spend more time sitting. "It's going to improve your posture, make you look leaner, make you look slimmer, and help prevent back pain," Tracy confirms. With practice, this engagement becomes automatic, creating lasting improvements in both appearance and well-being.

Start Today, See Results Tomorrow

Tracy emphasizes that consistency is key with all these approaches. The 20-second Tabata intervals might seem brief, but when performed regularly, they create significant changes. "When you do it with time, you don't even have to think about it anymore. It just becomes like a natural part of your day," she explains about her techniques.

By combining strategic 20-second workouts, stress reduction, smart nutrition, confident dressing, and simple posture adjustments, Tracy transformed her menopausal middle—and believes you can too.

Diet and exercise are two components of weight loss. However, if you want to transform your body, there are additional habits you need to incorporate into your routine. Amulya M is a weight loss coach and influencer who helps her followers lose weight and transform their lives. In a new viral post, she reveals her plan for a four-month transformation. “For the next 4 months become addicted to these 7 habits, and you’ll be unrecognizable by June 2025,” she writes.

Wake Up Early

Her first transformation habit is waking up earlier. According to Amulya, it gives you more time to workout, plan your day, work on business, and be more productive. “It is a huge life hack and gives you more time to achieve your goals,” she says.

We've consulted with our team of licensed nutritionists and dietitians to bring you informed recommendations for food products, health aids and nutritional goods to safely and successfully guide you toward making better diet and nutrition choices. We strive to only recommend products that adhere to our philosophy of eating better while still enjoying what you eat.

Once you hit 40, your metabolism slows down a bit. Paying attention to nutrition becomes more important to prevent weight gain or lose some pounds you may have accumulated. Maintaining or building muscle is also more complex, so good nutrition is key. As an experienced nutrition coach and nutritionist who spends a lot of time helping my clients lose weight, I often advise my clients to eat certain types of food to fuel fat loss. These are the best foods for weight loss if you are over 40.

Lean Protein

My first recommendation is lean protein, including chicken, fish, lean beef, tofu, eggs, and Greek yogurt. These foods help support muscle mass and keep you full longer. I recommend spreading protein throughout the day, having some at each meal especially breakfast. Also, choose grilled or baked instead of fried.

Leafy Greens

Another one of the best foods for weight loss is any leafy green. My favorites are spinach, kale, arugula, and romaine. Not only are these veggies low in calories, but they are also high in fiber and essential nutrients. An added bonus? Leafy greens are super high in antioxidants for disease fighting.

Berries

Another great food for weight loss that also serves as a sweet treat? Berries. Personally, my favorites are blackberries, blueberries, strawberries, and raspberries. What makes this type of fruit so special? Berries are packed with fiber, which promotes satiety and good digestive health. They are also low in sugar compared to other fruits and high in antioxidants.

Healthy Fats

Healthy fats – including avocados, nuts, and olives – are also excellent fat burners. They help keep you feeling full and satisfied, support brain and heart health, and are needed to help regulate hormones, which is crucial for weight management over 40.

Probiotic-Rich Foods

Whole Grains

Lastly, when it comes to carbs, fill your plate with whole grains. I recommend quinoa, brown rice, and oats.
