Here Is How to Lose 15 Pounds in 45 Days

Losing 15 pounds in two months is challenging but certainly not impossible once you set your mind to it. By adopting certain habits and sticking to them, you can reach your weight loss goals within eight weeks—and hopefully, maintain them. “For a successful — and lasting — weight management plan, you also need to increase your physical activity,” according to the Mayo Clinic. “Combining regular activity and healthy eating will help you get to and maintain a healthy weight.” Read on to find out more.

Log Your Food

Keeping a food diary has been shown to help with weight loss efforts. “A food diary can be a useful tool in this process,” Katherine D. McManus, MS, RD, LDN, tells Harvard Health. “It can help you understand your eating habits and patterns and help you identify the foods — good and not-so-good — you eat on a regular basis. Research shows that for people interested in losing weight, keeping a journal can be a very effective tool to help change behavior.”

Calorie Deficit

Track your calories and make sure you have a deficit to lose weight. “Your weight is a balancing act, but the equation is simple,” says the Mayo Clinic. “If you eat more calories than you burn, you gain weight. And if you eat fewer calories and burn more calories through physical activity, you lose weight.”

Walk Every Day

Taking a brisk walk of at least 30 minutes a day can help torch fat. “A lot of people have a hard time getting motivated to start exercising,” exercise physiologist Katie Lawton, MEd, tells the Cleveland Clinic. “But walking is simple, right? We do it every day.”

Be Mindful of Alcohol

Aside from being full of empty calories, alcohol can derail weight loss plans by encouraging overeating. “Across the board, for people who are trying to lose some weight, cutting out empty calories is a good place to start,” Leslie Heinberg, PhD, tells the Cleveland Clinic. “Oftentimes, beverages are a big source of empty calories — whether it’s soda, juice, sweet tea, beer, wine or cocktails. Any of those things add calories, but really without nutrition and without the sense of feeling full.”

Try Intermittent Fasting

Intermittent fasting can be a powerful weight loss tool. “Intermittent fasting contrasts with the normal eating pattern for most Americans, who eat throughout their waking hours,” says Johns Hopkins neuroscientist Mark Mattson, PhD. “If someone is eating three meals a day, plus snacks, and they’re not exercising, then every time they eat, they’re running on those calories and not burning their fat stores.”

Manage Your Stress

Stress causes cortisol to spike, which is shown to encourage weight gain through factors such as overeating and poor sleep. “The hormone raises your blood pressure and insulin production, while simultaneously suppressing your immune system. As your insulin levels go up, your blood sugar drops, making you crave fatty, sugary foods,” says the Cleveland Clinic.

Get Plenty of Sleep

Sleep is crucial for weight loss—aim for at least 7 hours a night. One study shows getting more sleep reduces intake. “Even within just two weeks, we have quantified evidence showing a decrease in caloric intake and a negative energy balance — caloric intake is less than calories burned,” says Esra Tasali, MD, Director of the UChicago Sleep Center at the University of Chicago Medicine. “If healthy sleep habits are maintained over longer duration, this would lead to clinically important weight loss over time. Many people are working hard to find ways to decrease their caloric intake to lose weight — well, just by sleeping more, you may be able to reduce it substantially.”

Do you want to lose 30 pounds in two weeks? While it might seem impossible, one YouTuber claims it isn’t. Steve Cha of Rockstar Eater, a YouTube channel focusing on his love of food, shared a recent video about how rapidly he lost weight to the tune of a pound every two days. He claims it all boils down to following three simple steps.

He Gained 10 to 12 Pounds After Starting His YouTube Channel

Steve from Rockstar Eater explains that he gained “about 10 to 12 pounds” after starting his YouTube channel from “eating a lot of food” and that “it did take some toll” on his body. He topped the scales at 170, admitting that his blood pressure and cholesterol both went up.

He Gave Himself 30 Days to Lose 15 Pounds

“So I decided that I'm going to take some steps in order to try to take care of my health for the next few weeks. So in this video, I'm gonna be documenting my journey on losing basically 10 to 15 pounds,” he says, giving himself a time frame of 30 days.

His Plan Starts with Exercise

Steve’s plan was to start with exercise. “What I'm gonna do is basically every day do a lot of walking, cardio, jogging in order to sweat, burn some calories,” he says.

It Also Involves Changing His Diet

“And I'm also gonna, of course, alter my diet. That's the most important thing because it's no use for me to go out and do all of this exercising but then come home and snack on all this junk food,” he says. “Of course, I'm not gonna go the drastic route of starving myself, you know, like what some people do. That's actually not healthy at all.”

Protein with Salads or Veggies

What will he be eating for the next few weeks while he’s trying to lose weight? “Definitely low-fat foods,” he says. He might make a big salad and some salmon but only have a third of it, then “probably the other third for dinner. And then for dinner, I can change it up by eating, for example, fish, some cucumber and some baby broccoli, which is really good. I highly recommend this.” He will also eat an apple.

No Fried Food

“So something like this is what I would be eating every day with just some variations, but definitely staying away from all the fried stuff, all the beef, you know, high cholesterol stuff, definitely no ice cream,” he adds.

10,000 Steps Per Day

Steve’s goal is to try to hit about 10,000 steps a day. “On a busy day, I'd probably be walking for about one hour, kind of like a walk-jog. But then, if I have one of those days where it's not that busy, who knows, I might even go for half a day, like three to four hours of walking. But remember, drink plenty of water when you're out here, especially during the summertime,” he says.

Week One He Lost 3 Pounds

“So it's been about a week now, and it looks like I've been able to lose about three pounds in the course of six to seven days. So far off to a good start,” Steve says. “I mean, I'm already feeling it. My body feels a little lighter, and I can get into my pants without feeling so very tight.”

Week Two He Lost Two-and-Half-Pounds

This week I was able to drop about two to two and a half pounds, and I do feel better. Everything feels good all around,” Steve says. If “you're losing weight over time, it gets more difficult and difficult to drop the same amount of weight every single week.”

He Did Cheat

Steve admits that he “did have some cheat days here and there, but for the most part, still sticking to vegetables, fruits, and cereal, oats, you know, all that healthy stuff, and I don't overeat. That's the key. And you gotta also do a lot of exercise.”

30 Day Mark: 15 Pounds

“Moment of truth after 30 days of hard work. Let's see what the final result is.

As many of you guys probably know, that was not an easy task to all of a sudden go onto such a strict diet exercising plan. So yes, it looks like I lost about 14 to 15 pounds in the span of 30 days, which is not easy to do, but it is doable though.”

Step 1: Diet

He then details each step he followed. “Number one, I changed my diet plan,” he reiterates, “eating stuff with less sugar, less sodium, less carbs in it, sticking mainly to fruits and vegetables and oats and wheat. I mean, once in a while, I had my cheat day here and there to eat something heavier, but that's pretty much what I've been sticking to.”

Step 2: Hydrating

The second step? Hydration. “ I've been drinking a lot of water, like a lot of water,” he continues. “No more of the sodas and the fruit juices, mostly water during a lot of these days.”

Step 3: Exercising

Shutterstock

His final step? Exercise, including “a lot of cardio, jogging, some stretches here and there,” he says.

It’s Not Easy, But Gets Easier

Steve encourages others to stick to a diet. “It's not easy, I'll tell you that, especially in the first few days. It's gonna be very difficult, but then you kind of get used to it over time,” he says.

His Blood Pressure Decreased

“But overall, I'm definitely feeling it. It's flatter all around my stomach area and my chest and I feel better health-wise. And I was even able to go to the local grocery store to measure my blood pressure. It actually went down by 15, I think I was at 1 35 before in terms of blood pressure. And then I think it went down to about like one 20 or one 17, which is really good.”

So Did His Body Fat

Shutterstock

His “body fat level has gone down a little bit as well, and I'm assuming that's also cholesterol,” he notes. “So overall, I'm feeling very healthy. So if you guys want to lose some weight and you want to lose it fast, maybe within 30 days, just letting you know that it is possible.”

The NIH Recommends Losing 1 to 2 Pounds Per Week

Is Steve’s weight loss realistic? According to the National Institutes of Health, no. “Weight loss should be about 1 to 2 pounds per week for a period of 6 months,” they say. That would be a maximum loss of 8 pounds in 30 days.

Body Network’s Expert Weighs In

Tara Collingwood

Body Network’s Resident RDN, Tara Collingwood, MS, RDN, CSSD, LD/N, ACSM-CPT, a Board Certified Sports Dietitian and co-author of the Flat Belly Cookbook for Dummies, agrees that starving yourself thin is not a good idea. She notes that rapid weight loss usually leads to weight regain. “Starving and fasting can produce fast weight loss, but it also stresses the body and causes the metabolism to shut down, which in turn can cause rebound weight gain,” she says.

However, sustainable weight loss is possible with the right mindset and approach. "Anything hard takes some discipline, and losing weight is one of the hardest lifestyle habits to modify," says Collingwood. "I coach my clients to think about their motivations for eating to make the changes in their lifestyle that will require them to lose the weight they say they want to lose. With discomfort comes growth and results." she says. And if you enjoyed this article, take advantage of these 15 Quick Ways to Lose Body Fat Percentage in a Week.
