Isis Kellier is a diet and fitness influencer who regularly shares videos on her channel about how she lost weight fast and got into the best shape of her life. In one TikTok video she reveals how she dropped an average of 2.5 pounds a week by making a few simple changes to her diet and fitness routine. “How I lost 15 pounds in six weeks,” she starts the clip, going on to reveal her secrets. We also asked The Diet Diva, Tara Collingwood, MS, RDN, CSSD, LD/N, ACSM-CPT, a Board Certified Sports Dietitian, to weigh in on her tactics.

1. Intermittent Fasting

The first thing Isis did? Intermittent fasting, or “OMAD,” she reveals, which stands for “one meal a day. “The Lightly intermittent fasting app helps to keep everything on track,” she added. In another video she details what she eats in a day, starting at 2:00 pm with two glasses of green juice followed by a bowl of fruit. For her main meal of the day, “dinner,” she eats at 4:00 pm and enjoys spicy vodka pasta with a grilled chicken breast on top. At 5:30 pm she drinks two Premiere Protein shakes.

2. Expert Weighs in on OMAD

“It sounds like she is only eating in a less than 4 hour window which is a very small eating window,” Collingwood notes. “I like that she has antioxidant rich green juice and fruit, but that is not really a ton of produce or fiber. When you eat most of your produce as juice, you are missing out on a lot of fiber which is really important for gut health and keeping the microbiome in check.” As for protein, she is likely meeting her requirements with the grilled chicken, “not sure size but let’s assume 4 oz = 28 grams of protein and two premier protein shakes at 30 grams each gives her another 60 grams to push her over 80 grams for the day,” she notes. “However, two highly processed protein shakes are not really providing the quality of food we like for overall good health. They do have a lot of vitamins and minerals added to them, which she needs because she is not eating very many calories or a variety of foods.” She is happy to see some carbs in the pasta, “but vodka sauce does not really provide much nutritional value,” she adds. “ Marinara would be much better with the antioxidants and nutrients in tomatoes.” Overall Collingwood is concerned about her low calorie intake. “Again, I don’t have exact portion sizes but I estimate this to be about 1000-1200 calories.”

Next up? “30 to 60 minutes of cardio daily,” she reveals. In the other video she reveals that she does “fasted cardio” in the morning prior to her first meal.

According to Collingwood, 30 to 60 minutes of cardio “is great,” she says. However, “if she is doing this in the morning and not getting any calories until 2 PM (and that is very few with the green juice and fruit and no protein) she is leaving her body susceptible to poor recovery, injury risk, dehydration, and low energy,” she points out.

5. Calorie Deficit

Her final secret to losing 15 pounds in six weeks? Maintaining a “caloric deficit,” she says. The basic math of calories in vs calories out is caloric deficit which is necessary to lose weight, Collingwood agrees. “But you can create a caloric deficit in many other more healthy ways that include fueling the body in more regular intervals, feeding more nutritious foods, and having more balance.”

6. Bottom Line: Is a 15-Pound Weight Loss in 6 Weeks Realistic?

Collingwood and most experts agree that a healthy weight loss rate is typically one to two pounds per week. “15 pounds in 6 weeks is a bit higher than that,” Collingwood points out. “It all depends on how much weight someone has to lose. If you have 100 pounds you lose, it will come off faster initially. If you only have 15 pounds to lose, the weight will come off more slowly.

In general, the faster it comes off, the more likely there is a higher proportion of muscle coming off vs a majority of fat tissue.”

Jenna Evelyn (@jennaevelyn) is a beauty and lifestyle influencer on TikTok who regularly shares about her weight loss journey. According to Jenna, she lost “15 to 20 pounds in two to three months” after “gaining the freshman 15” while living on campus during her first year of college. In one of her many viral TikTok videos, she reveals how she lost weight using five simple hacks.

1. Jenna Gained “About 30” Pounds From Drinking Every Weekend and Other Unhealthy Habits

Jenna, who is currently a college student, reveals that she “probably gained about 20 pounds” while being a freshman in college due to “drinking every weekend, not being in a deficit, not hitting my protein goals, and not working out the right way for my body,” she reveals in her viral video. “Here's what I did to actually lose the 15 to 20 pounds very quickly.”

2. Low Calorie, High Protein Meals

According to Jenna “food was the biggest thing,” when it came to her weight loss. “I was still eating a lot, but it was low calorie, high protein,” she added. Her “staples” for low cal high protein meals? “Chickpea pasta” and fat free cottage cheese, which she made sauces out of and “used it in everything,” she added. She also ate a lot of ground turkey. “I would make taco bowls,” she said. She also ate chicken and Greek yogurt “all the time” and turkey bacon. “I'd make breakfast sandwiches,” she added. Research supporting amping up protein intake for weight loss. According to clinical trials, consuming more protein than the recommended dietary allowance not only reduces body weight (BW), but also enhances body composition by decreasing fat mass while preserving fat-free mass (FFM) in both low-calorie and standard-calorie diets.

Jenna maintains that she started losing weight, when she started doing “low impact workouts, like walking dumbbell only lifts, and Pilates,” she said. “Here was my weekly workout split: Monday dumbbell only glutes Tuesday, full body Pilates. Wednesday, back buys, arms, dumbbell only Thursday, Pilates Friday, quad dumbbell, only Saturday cardio.”

4. 10,000 Steps a Day

Jenna explains that one “huge” component of her weight loss was walking. “Hit your 10,000 steps a day,” she says. “Some of those steps for me before my workouts would come from walking, doing the 12-3-30 workout or the stair stepper.” The 12-3-30 workout involves using a treadmill and walking on a level 12 incline at a speed of 3 for 30 minutes. Experts maintain that it burns more calories than walking fast or even running on a flat surface. And, studies, including a 2018 study published in the journal Obesity, have found that walking around 10,000 steps per day can help you lose weight. But that’s not the only benefit of getting your steps in. 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.

5. Meal Prep

Finally, meal prepping and using high quality ingredients, was a key part of Jenna’s weight loss plan. “It was so important that I made enough time to meal prep local, high protein meals so that they were always on hand,” she said. There is scientific evidence supporting the benefits of meal planning. Studies the more meals you eat prepared away from home, the higher your risk of cardiovascular disease, cancer, and early death. And, one study published in the International Journal of Behavioral Nutrition and Physical Activity found meal planning was associated with a healthier diet and less obesity.
