The most popular supplement in America isn’t Vitamin C or a multivitamin—it’s Vitamin D. Vitamin D regulates your calcium levels, vital for healthy bones, and facilitates normal immune system function. So how do you know if you need it too? “Lack of vitamin D is not quite as obvious in adults,” says the Cleveland Clinic. “Signs and symptoms might include” the following.

You Might Feel Fatigue

“Vitamin D deficiency is frequent and has been associated with fatigue and other unspecific symptoms including headache, musculoskeletal pain and weakness, depression, and impaired cognitive performance,” says one study published in Medicine. “Vitamin D treatment significantly improved fatigue in otherwise healthy persons with vitamin D deficiency.”

You Might Feel Bone Pain

“Vitamin D status influences musculoskeletal health,” says one study published in Musculoskeletal Medicine. “Low vitamin D levels may lead to clinical manifestations, including bone pain, muscle weakness, falls, low bone mass, and fractures, with subsequent diagnoses of osteomalacia, osteoporosis, and myopathy.”

You Might Feel Muscle Weakness, Muscle Aches, or Muscle Cramps

“Vitamin D is increasingly recognized to play an important role in normal muscle function,” say the authors of one study published in Bone Reports. “Low vitamin D status is associated with an increased risk of falls and proximal weakness. Since vitamin D deficiency is very common, and the signs are non-specific, it is important to maintain a high index of suspicion of vitamin D deficiency in patients with muscle pain and weakness.”

You Might Have Mood Changes, Like Depression

“Depression in its own right is a disabling condition impairing all aspects of human function,” say the authors of a study in Issues in Mental Health Nursing. “In persons with a chronic medical disease, depression often makes the management of chronic illness more difficult. Recently, vitamin D has been reported in the scientific and lay press as an important factor that may have significant health benefits in the prevention and treatment of many chronic illnesses. Most individuals in this country have insufficient levels of vitamin D. This is also true for persons with depression as well as other mental disorders.”

If You’re a Child, You Could Get Rickets

“Severe lack of vitamin D causes rickets, which shows up in children as incorrect growth patterns, weakness in muscles, pain in bones and deformities in joints,” says the Cleveland Clinic. “This is very rare. However, children who are deficient in vitamin D can also have muscle weakness or sore and painful muscles.”

“Your doctor can order a blood test to measure your levels of vitamin D,” says the Cleveland Clinic. “There are two types of tests that might be ordered, but the most common is the 25-hydroxyvitamin D, known as 25(OH)D for short. For the blood test, a technician will use a needle to take blood from a vein. You do not need to fast or otherwise prepare for this type of test.” And if you enjoyed this article, take advantage of these 15 Quick Ways to Lose Body Fat Percentage in a Week.

6 Warning Signs Your Body Desperately Needs Vitamin B1

Our team of licensed nutritionists and dietitians strives to be objective, unbiased, and honest.

We are committed to bringing you researched, expert-driven content to help you make more informed decisions around food, health, and wellness. We know how important making choices about your overall health is, and we strive to provide you with the best information possible.

Do you experience tingling in your hands, sharp pain shooting down your legs, or numbness in your feet? These could be warning signs that your body is desperately lacking essential vitamins, particularly vitamin B1. Dr. Eric Berg DC, a renowned expert in healthy ketosis and intermittent fasting, explains that vitamin deficiencies are behind most nerve problems, with B1 deficiency being the most common culprit. "The most common nerve problem that exists is something relating to either prediabetes or diabetes," says Dr. Berg. Learn how to identify these warning signs and discover the simple solutions that could reverse your nerve damage and help you live pain-free.

Warning Sign 6 Viral Nerve Pain After Stress

Certain viruses can hide in nerve bundles called ganglia, explains Dr. Berg. "What's unique about these viruses is they go into those areas, those little bundles, to evade the immune system and fly underneath the radar," he notes. These viruses can deactivate autophagy—your body's natural recycling system for damaged proteins and pathogens.

Stress Triggers Hidden Viruses

According to Dr. Berg, these dormant viruses often emerge after stressful events. "Cortisol is an immune suppressant. One of the most severe stresses someone can go through is emotional stress. This is why a lot of these dormant viruses come out of remission after a stress event," Dr. Berg explains.

Fight Viruses With This Amino Acid

There's an important relationship between two amino acids that can help combat these viruses. "These viruses need the amino acid called arginine to exist. And it just so happens that arginine competes with another amino acid called lysine," says Dr. Berg. If you supplement with enough lysine, you can block arginine and stop viral reproduction.

How Much Lysine You Need Daily

Dr. Berg recommends: "You have to take a lot of lysine to compete and block arginine. You want to take 1000 milligrams to 3000 milligrams every single day for a period of time to put that virus back in remission, as well as do whatever you can to reduce stress."

Warning Sign 4 Sciatica and Back Pain

Sciatica pain usually originates from disc issues, and Dr. Berg has identified a common deficiency in these cases. "A lot of people with disc problems are deficient in copper," he states. For relief, Dr. Berg suggests "either taking a supplement with copper or just putting copper cream topically around that area in your back where it originates to reduce the discomfort."

Warning Sign 3 Wrist Pain and Weakness

For the common wrist condition known as carpal tunnel syndrome, Dr. Berg points to a specific B vitamin deficiency. "This is usually a B6 deficiency," he explains. Addressing this specific deficiency can help relieve pressure on the median nerve in the wrist.

Warning Sign 2 Electric Shock Sensations

The protective sheath around your nerves requires specific nutrients to stay healthy. "If you're deficient in B12, you can get electric shock-like sensations in your nervous system, very painful or even numbness," says Dr. Berg.

Your Nerve's Protective Coating

Portrait Of Young Arab Man With Shoulder Pain Suffering Sport Injury During Training At Gym, Middle Eastern Male Athlete Having Trauma After Fitness Workout, Rubbing Painful Area, CloseupShutterstock

Dr. Berg explains why this happens: "B12 is involved with the myelin sheath around the nerve. That's the outer covering that protects the nerve, insulates it, and allows the signals to transmit."

Autoimmune Conditions and Vitamin D3

For autoimmune conditions affecting the nerves like Multiple Sclerosis (MS), Dr. Berg recommends a specific vitamin. "Vitamin D3 is essential in reducing inflammation within the nerve cells and also your brain cells," he states.

High-Dose Vitamin D3 Strategy

The dosage needed may be substantial. "You need to take large amounts of vitamin D3, 50, 60, 70, 80,000 IU of vitamin D3 to put that condition into remission," according to Dr. Berg, who references the Coimbra protocol for this approach.

The 1 Vitamin for Nerve Health

The most common nerve problems are related to high blood sugar levels. "A lot of people with diabetes end up with nerve problems in their feet. They get numbness in the toes first, and then it kind of starts traveling in the foot," Dr. Berg explains.

The 1 Fix for Diabetic Nerve Pain

What's causing this damage? "The sugar in the blood is creating such a demand for this one vitamin. That vitamin is called vitamin B1, thiamine," says Dr. Berg.

Why B1 Is Critical For Nerve Health

Dr. Berg clarifies the relationship between diet and this deficiency: "The more carbohydrates or sugar someone consumes, the greater the need for B1. If you're prediabetic or diabetic, you have a lot of sugar going through the bloodstream. That means you're going to need even more B1 to compensate."

Try This Special Form of B1

He specifically recommends a form called benfotiamine: "I would take it in the form of benfotiamine because that tends to penetrate the myelin and get right into the nerve and very quickly reverse nerve damage that's caused from high sugar."

For B1 to work effectively, Dr. Berg points out another crucial nutrient: "In order for B1 to work, there's another cofactor that you need and that's magnesium." This mineral works synergistically with B1 to support proper nerve function and health.

Do you have a nutritional deficiency? According to research, nutritional deficiencies may cause developmental failure, loss of various body functions, and several other diseases, such as diabetes, vision loss, immunity loss, and cancer. What are the major causes of nutritional deficiencies? Insufficient intake of food, inability to absorb nutrients, and consumption of diets that lack some of the essential nutrients. So, how do you know if your body needs more nutrients? Janine Bowring, ND, is a naturopathic doctor, best-selling author, researcher, and formulator. In a new video, she answers the burning question. “Here are six signs your body needs more nutrients,” she says in the YouTube clip.

Muscle Spasms

https://youtube.com/shorts/-H165m1iV-s?si=_VLtZThW_tmyqSGJ

The first symptom that can signal a nutritional deficiency? “Number one, muscle spasms,” Dr. Bowring says, noting the symptom is also referred to as “Charlie horses.” What does this signal? “A magnesium deficiency,” she says, noting that you can take a magnesium supplement.

Teeth Grinding

Do you wake up in the morning with a sore jaw? “Number two, if you grind your teeth at night, that can be an indication of parasites,” she says. She adds that it could also be due to a probiotic deficiency. The solution? Amp up your probiotic intake. You can do this by eating a probiotic-rich food or taking a supplement.

Keratosis Pilaris

Nutritional deficiencies can manifest in dermatological issues. “Number three, keratosis pilaris,” Dr. Bowring reveals. “Those bumps on the backs of the arms” may be a sign that you have a vitamin C and vitamin A deficiency. “You could have a low thyroid as well,” she says.

Hair Loss

Does it seem like your hair is shedding? Number four on Dr. Bowring’s list is hair loss. “This can be related to low iron, omega 3s, and low protein,” she says.

Numbness or Tingling

Think you're getting enough protein? Many of us don't, and the signs aren't always obvious. In this revealing countdown, we'll explore ten increasingly important signs of protein deficiency, starting with subtle hints and building up to serious warning signals that demand attention.

Dr. Ken Berry, a family physician with over 20 years of clinical experience, brings crucial insights about protein deficiency that could transform your health. As he explains, "There are sources of information out there that will tell you that eating too much protein is bad for you... In fact, nothing could be further from the truth." Join us as we count down these essential warning signs that could help you identify and correct this common deficiency.

Sleep Disruptions – The Surprising Sign

The countdown begins with an unexpected connection. Dr. Berry shares his own surprise at this finding: "When I was doing the research for this video, I did not know that a protein deficiency can lead to insomnia, but it's actually quite well known in the sleep literature," he says in his video post.

Mood Changes

Your protein intake might be affecting your emotional well-being more than you realize. As Dr. Berry notes, "If you're always down in the dumps, you always have a negative mood, this is actually a sign of protein deficiency."

Unusual Cravings and Hunger

Those persistent cravings aren't random. Dr. Berry explains, "Your body's looking for a very short list of nutrients in your diet. It's looking for amino acids that come from protein... If you're not getting enough protein in your diet, then your body is going to increase your hunger and it's going to make you have these weird cravings trying to get the particular amino acid or protein molecule that it's looking for."

Brittle Hair, Nails, and Skin Issues

Physical appearance often reflects internal nutrition. Dr. Berry warns, "If your skin is dry and flaky and very thin, if your nails break very easily or they flake up very easily, if your hair's brittle and breaks, if you're having hair loss for no apparent reason, these are all signs of protein deficiency."

Slow-Healing Wounds

Scars on the faceShutterstock

Notice how long it takes for cuts and scrapes to heal? Dr. Berry points out, "If you've been eating low protein for years or decades, then you've gotten used to how long it takes for your wounds to heal, so you may not recognize your wound healing as slow, so maybe ask some friends and relatives how long it takes for a scrape or a cut or an abrasion to heal."

Frequent Infections

Sick woman with headache sitting under the blanketShutterstock

Your immune system needs protein to function properly. Dr. Berry explains, "If you have frequent upper respiratory infections or frequent bladder infections or frequent skin infections... Your immune system has to have a lot of protein in order to fight off infections, whether we're talking about bacterial infections or viral infections."

Stunted Growth in Children

For children, protein deficiency can have lasting consequences. "Stunning growth is almost always due, at least in part to a protein deficiency," Dr. Berry emphasizes. "The child just not getting enough protein... if you want your child to grow up to be tall and strong and beautiful and intelligent, they've got to get enough protein in their diet."

Muscle Loss

Muscle health is a crucial indicator. Dr. Berry states, "A very common sign of protein deficiency is muscle loss or the inability to gain muscle. This is very common in the elderly. As they don't eat enough protein, they lose their muscle mass. In some athletes, if they're not eating enough protein, they work out really hard and they don't gain muscle at all."

Decreased Bone Strength

This sign challenges common misconceptions. Dr. Berry explains, "Most people think bones are made of calcium. They're actually made of protein with a calcium atom stuck into the matrix of the protein. Your bones are all protein, and if you're not eating enough protein, your body will not be able to keep your bones strong."

Severe Edema

In advanced cases, protein deficiency can lead to visible swelling. Dr. Berry warns, "If you have a severe terrible protein deficiency, you can actually develop edema or swelling in your ankles and feet. This is kind of an end stage sign when you've been protein deficient for so long that your body's about to give up."

Expert Recommendations: Getting Enough Protein

Dr. Berry recommends focusing on whole food sources: "The best sources for protein that I recommend are meat, fish, eggs, and cheese." He specifically notes, "Never ever do you need a protein shake or a protein bar or a protein powder. Those are usually wind up being carbohydrate shakes in bars and powders."

For optimal intake, he advises "two grams of protein per kilogram of body weight, or if you're in the United States, then one gram of protein per pound of body weight." He emphasizes that this isn't excessive: "Protein's good for your kidneys, protein's good for your bones. Protein is good for every other part of you."


Special attention should be paid to at-risk groups: elderly individuals who might default to simple carbohydrates, women (especially during pregnancy and breastfeeding), and growing children who might prefer snacks over protein-rich foods.

Ever feel exhausted despite getting enough sleep? Notice your workouts taking longer to recover from? These could be your body's way of saying you need more protein. While severe protein deficiency is rare in developed countries, even mild insufficiency can impact your daily life and long-term health.

As a holistic health expert and former Olympic athlete, Dr. Sten Ekberg brings a unique perspective to nutrition and wellness. With his background in functional medicine and chiropractic care, combined with his experience as a Swedish national record holder in decathlon, he helps people understand their body's signals and optimize their health through proper nutrition.

Here are the key signs that might indicate you need more protein in your diet.

Your Muscles Are Sending Warning Signals

"Muscle-related issues are often the first sign of protein deficiency," says Dr. Ekberg in his post. He explains that weakness, slow recovery after workouts, and muscle cramps can all indicate low protein levels. "Your muscles are primarily made of protein. Without enough, you can't repair muscle fibers or regulate electrolytes properly, which can lead to cramping."

Wounds Take Longer to Heal

Protein plays a crucial role in healing. "Most tissue in your body is made up of protein," Dr. Ekberg notes. "When you're low on protein, wound healing can slow significantly because your body lacks the building blocks for repair."

Your Hair, Nails and Skin Are Suffering

"Keratin and collagen are the two main proteins that keep your hair, nails, and skin healthy," Dr. Ekberg explains. "Without adequate protein intake, your body can't produce enough of these structural proteins." Watch for weak, brittle nails, thinning hair, and dry, flaky skin – all potential signs of protein deficiency.

Digestive Issues Are Becoming Common

Most people don't realize that digestion relies heavily on protein. "Every digestive enzyme in your body is made from protein," Dr. Ekberg points out. "From the amylase in your mouth to the enzymes in your intestines, protein deficiency can compromise your entire digestive process."

You're Getting Sick More Often

Sick woman with headache sitting under the blanketShutterstock

"Your immune system depends heavily on protein," Dr. Ekberg emphasizes. "Antibodies that fight infection are actually large protein molecules. When you're low on protein, your body struggles to produce enough antibodies and white blood cells to maintain strong immunity."

Your Hormones Feel Out of Balance

Dr. Ekberg notes that many essential hormones – including insulin, growth hormone, and thyroid-stimulating hormone – are made of protein. "When protein levels drop, hormone production can be disrupted, affecting everything from your metabolism to your stress response."

Fatigue Has Become Your New Normal

"Protein deficiency can cause fatigue in two ways," Dr. Ekberg explains. "First, hemoglobin, the protein that carries oxygen in your blood, may decrease, leading to anemia. Second, the enzymes that regulate energy production require protein to function properly."

Brain Fog Is Affecting Your Focus

Mental clarity can suffer when protein is low. "Your brain relies on protein-based neurotransmitters to function properly," says Dr. Ekberg. "Without enough protein, you might experience brain fog, difficulty concentrating, and mood changes."

Your Bones and Joints Are Weakening

"Many people are surprised to learn that bone is 30% protein," Dr. Ekberg reveals. "The protein matrix must be strong before calcium can properly mineralize it. Low protein intake can lead to weaker bones and joint problems over time."

You're Experiencing Fluid Retention

Swollen feets because water retention in the bodyShutterstock

"Albumin, the most abundant protein in your blood, helps maintain proper fluid balance," Dr. Ekberg explains. "When protein levels drop, fluid can leak into surrounding tissues, causing swelling and puffiness, particularly around the ankles and knees."

How Much Protein Do You Really Need?

The daily protein requirement varies based on age, weight, and activity level. While the basic recommended dietary allowance is 0.8 grams of protein per kilogram of body weight, many experts now suggest this might not be enough, especially for older adults. Dr. Michelle Oppezzo, a nutrition expert, recommends "between 1.2 to 1.6 grams per kilogram of body weight for adults over 50, which is roughly double the federal recommendation." This higher intake helps maintain muscle mass and overall health as we age.

Getting enough protein isn't just about the total amount – timing matters too. "Aim for 0.4 grams of protein per kilogram of body weight at each meal," Dr. Oppezzo advises. For a 165-pound person, this translates to about 30 grams of protein per meal. Research supports spreading protein intake across three daily meals, with 25-30 grams of high-quality protein at each sitting for optimal muscle health and nutrition.

Remember, while these signs might indicate protein deficiency, they could also stem from other causes. If you're experiencing any of these symptoms, consult with a healthcare provider for proper diagnosis and treatment. Focus on incorporating a variety of protein-rich foods into your diet and consider your individual needs based on your age, activity level, and overall health status.

Depending on your starting weight, losing five to 10 pounds in a month is possible to do in a healthy way. Making a few specific lifestyle and dietary changes and sticking to them will positively impact overall health as well as encourage weight loss. “The foundation of successful weight loss remains a healthy, calorie-controlled diet combined with increased physical activity,” says the Mayo Clinic. “For successful, long-term weight loss, you must make permanent changes in your lifestyle and health habits.” Here are 15 daily habits shown to help lose up to ten pounds in 30 days.

Eliminate Empty Calories

Alcohol is full of empty calories, so it’s best to cut down or simply stop drinking it altogether. Every calorie counts when you’re trying to lose weight, so make sure you use those calories to fill your body with healthy, nutrient-dense choices. Drinking too much also disrupts sleep.

Are You Actually Hungry?

Eat when you’re hungry, and only when you’re hungry. “Listening to your hunger works much better than relying on willpower,” Kayla Kopp, RD, LD, tells the Cleveland Clinic. “When you’re tempted to overeat, have a conversation with yourself: Are you feeling hungry, are you bored or are you feeling emotional? Will eating right now get you closer to your goal?”

Work Out First Thing

Working out first thing in the morning means you don’t have to make time for it later. It also starts the day off on a good note. No excuses!

Don’t Skip Breakfast

Studies show people who eat breakfast (provided it’s a healthy one) make better food choices for the rest of the day. "Studies have found that although people who skip breakfast eat slightly fewer calories during the day, they tend to have higher body mass index, or BMI," Christy C. Tangney, PhD, tells Rush University Medical Center.

Take the Stairs

Walk as much as possible—park away from the grocery store entrance and take the stairs when possible. Walking will encourage fat burning and mental wellness, and you can do it throughout the day, no equipment needed.

Count Your Calories

This one is boring but crucial—to lose weight, you need to take in less calories than you’re burning off. “For example, to lose 1 to 2 pounds a week — a rate that experts consider safe — your food consumption should provide 500 to 1,000 calories less than your total weight-maintenance calories,” says Harvard Health.

Try Intermittent Fasting

Intermittent fasting can be a powerful weight loss tool for some. “The weight loss effects of time-restricted eating derive primarily from achieving a negative energy balance,” Richard Joseph, MD, tells Harvard Health. “If you maintain your regular diet and then limit the time window during which you eat, it is likely that you will eat a few hundred fewer calories per day.”

No Nighttime Snacking

Snacking can undermine your healthy eating weight loss plan. “Try to eat most of your daily calories before sitting down to relax for the night,” Kopp tells the Cleveland Clinic. “Many of us have a tendency to overeat without thinking about it while we watch TV after dinner, and we tend to forget just how much we’ve had before calling it a night.”

Be Picky About Carbs

You don’t have to eliminate carbs—but be choosy about them. “Not all carbohydrates are created equal,” says Corewell Health. “Eating a slice of white bread won’t give your body the same nutrition as eating a slice of whole grain bread. When you’re looking for options for carbohydrates, look at the ingredients. If the first ingredient is a whole grain (like whole wheat), you’re going in the right direction.”

Eliminate Temptation

Keep junk food out of sight and out of mind. “Don’t keep problem foods around the house and/or at work,” says UC Davis Health. A problem food is a food that you are likely to eat too much of or too often if readily available.”

Get Enough Sleep

Sleep is important for weight loss. “No one can make mindful food choices when they’re tired. Even missing an hour of sleep can increase your appetite because your body is craving that energy and food is fuel for your body,” psychologist Susan Albers, PsyD, tells the Cleveland Clinic. “You need a clear, focused head to make healthier food choices.”

Lift Weights

“Resistance training can also be a really effective way of losing weight," Tessa Strain, physical activity epidemiologist at the University of Cambridge, tells The Telegraph. “All weight loss comes down to a calories in/calories out equation. resistance training is a really effective way of losing weight because you’re expending energy, which involves burning calories.”

Manage Stress

Stress can undermine your weight loss efforts. “More commonly, people turn to — or away from — food as a way to help deal with stress,” says Penn Medicine. “Your metabolism can change if you regularly eat large amounts of food or don’t eat enough or at all.”

No Junk Food

Ultra-processed foods are terrible for weight loss. Not only will they not fill you up, they could make you hungrier. “Processed and fast foods contain enhanced ingredients that hit the dopamine center in your brain and make you want more,” Dr. Albers tells the Cleveland Clinic. “They are designed to be addictive to the brain.”

Drink More Water

Choose water over high-calorie drinks. “Sometimes we respond to thirst signals by eating — when actually what our bodies want is water,” Dr. Albers explains. “It’s easy to confuse our thirst and hunger signals, or to override thirst signals.”

The Simple Walking Routine That Helped Me Lose 40 Pounds

Can you lose a significant amount of weight just by walking every day? Yes, absolutely! Not only does walking burn fat, help lower blood pressure, and improve cholesterol levels, but it also does wonders for your mental state as well. “You need to make it part of your routine,” exercise physiologist Katie Lawton, MEd. tells Cleveland Clinic Health Essentials. “This is about adjusting your lifestyle for your health.” TikTok influencer Alex ( @alex.fitt) lost 40 pounds just by walking—here’s how she did it.

Don’t Start Big

@alexx.fitt Step by step walk it off #walking #weightloss ♬ original sound - alexx.fitt

Alex makes the important point that it’s better to start off slow to build sustainable habits. You don’t have to kickstart your fitness regimen with two-hour walks. Even just half an hour will make a difference to your mood and your health, and encourage you to do it again the next day.

Walking After Meals

Alex says she started off her walking program by simply taking a 15 minute walk after a big meal. Research shows walking after meals can benefit blood sugar. “Exercise impacts your blood sugar quickly, often within a few minutes,” Shannon Knapp, MEd, BSN, RN, CDCES, tells the Cleveland Clinic. “And over time, physical activity helps your body use insulin more effectively, decreasing the insulin resistance we often see in diabetes.”

Walking In the Morning

Alex would start her day with a walk. “Getting outside gives you a chance to enjoy fresh air and nature,” says Henry Ford Health. “Walking, like any form of exercise, reduces stress and anxiety. You’ll start the day with a positive attitude, better able to manage challenges during the day.”

Long Walk After Dinner

Alex would save her long walk for after dinner, which studies show is very beneficial. “The closer we get to the evening, the less efficient our bodies are at using insulin to deal with blood glucose, making it harder to keep blood glucose levels healthy,” Dr Evelyn Parr from the Australian Catholic University’s Exercise and Nutrition Research Program tells the Sydney Morning Herald. “Yet this is when we have our biggest meal of the day.”

Smaller Waist

Alex says the biggest difference she noticed from walking was in her waist. “The faster, farther and more frequently you walk, the greater the benefits,” says the Mayo Clinic. “For example, you may start out as an average walker, and then work your way up to walking faster and walking a mile in a shorter amount of time than an average walker, similar to power walkers.”

Using Technology

Alex was thrilled the first time her watch buzzed when she hit 10k steps. Research shows people who track their fitness tend to be successful. “We’ve seen this rise of digital health tools in the last decade, and they provide a great way for people to access interventions to better their health,” Michele Patel, PhD, tells Stanford Medicine.

10,000 Steps a Day

No matter how long or short her walks, Alex always aims for 10,000 steps every day. “Evidence suggests that accumulating up to 10,000 steps per day is helpful for reducing chronic conditions such as cardiovascular disease, type 2 diabetes, and some forms of cancer,” John M. Jakicic, Ph.D, tells University of Kansas Medical Center. “And more recent evidence supports the benefits of reducing the risk of dementia.”

Denise Hamdan (@denisehamdan) is a food and fitness influencer on TikTok who regularly shares her tricks and tips on weight loss with her 71,000 followers. Hamdan lost a whopping 30 pounds by following a healthy diet and exercising. In a recent clip, she reveals her diet. “Hey y'all, here's everything I ate in one day to stay lean as someone who lost 30 pounds,” she says, revealing that she eats 1829 calories and 147 g of protein per day. 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, also weighs in.

Breakfast

“I started my morning with my breakfast cocktail of oxygen and creatine. I just added the products to my showcase. So go check them out. I have my cocktail with Greek yogurt with strawberries and blueberries and a drizzle of granola,” she says. The total calories equal 157 and 14 g protein.

Lunch

“I'm in this phase where I eat nearly the same thing every day, and that's been scrambled eggs with cheese and spinach and some turkey bacon on the side,” she says about her lunch. “And honestly, I'm not complaining because it hits every time. Her total calories are 562 and 52 g protein.

Green Smoothie

Sometimes she will have a smoothie instead. “I made a cute little green smoothie and it was a little messy, but it was good regardless,” she says.

Pre-Workout Snack

“Later, for a pre-workout snack, I made some cute little tuna crackers with the green onion and bell pepper,” she says about the snack totaling 430 calories and 28 g protein.

OxyShred and Pre-Workout

“Then I got to the gym and made my OxyShred and pre-workout combo before hitting cardio and abs,” she continued. “It had me sweating.”

Protein Bar

“Right after my workout I had my favorite dark chocolate pretzel protein bar,” she continued.

Dinner

“And finally for dinner I made this super easy teriyaki chicken bowl over brown rice,” she said, adding that the 560 calorie and 52 gram protein meal is “so delicious and the macros forward are amazing.”

Dessert

“Lastly, for dessert, I had some chocolate 'cause I cannot end the day without a little sweet treat,” she said about the 120 calorie sweet treat.

RDN Weighs in

“1800-1900 calories seems like a good amount for her, but I don’t know her exact age, height, weight, or exercise level,” says Collingwood. “147 grams of protein is probably more than she needs, but it is not dangerously high.”

Try Eating More Vegetables, Expert Says

“I see a little bit of fruit on the yogurt and a tiny bit of spinach in eggs and peppers in tuna but overall not much veggie intake (green smoothie was green powder and not real whole veggies) which is proven with only 16 grams of fiber for her overall day,” Collingwood continues. “I would recommend increasing veggies to aim for 25 grams of fiber each day.” She also likes how often she is eating with the meals and snacks in between. “I do worry about the OxyShred. I couldn’t find on their website anywhere exactly how much caffeine is in it and having it later in the day could definitely impact sleep since caffeine has a 5 hour half-life,” she points out.
