On average, the daily caloric intake on Nutrisystem is 1,500 calories for men and 1,200 for women (low enough to lose weight but high enough to prevent “hangryness”). The daily menus are high in fiber to help you feel full, and are divided as follows: 50% carbs, 25% fat, 25% protein. According to a 2015 study by the American College of Physicians, people on Nutrisystem lose 3.8% more bodyweight than dieters who only receive guidance and counseling. Plus, thousands of positive customer reviews attest to Nutrisystem’s effectiveness, as long as you follow the program faithfully.
"It's no big surprise, but my go-to weight loss tip is to eat more vegetables. They are the most low-calorie food you can consume, and they're filled with health-boosting, satiating nutrients. From smoothies and eggs to soups, main and side dishes, they can fit in anywhere and boost volume and nutrition. If you want to eat more while still losing weight, veggies are your answer. —Laura Burak, RD, CDN
Research also finds that drinking frequently—even if it’s a moderate amount—can set you up for excess pudge. Not only do the beverages themselves contain unnecessary calories, but once you start sipping too much, your inhibition also plummets, according to one 2016 study. The result? You’ll have a hard time resisting that late-night slice of pizza. So if you're going to imbibe, be sure to stick to one drink per day for women and up to two drinks for men.
Even if you do meet your goal, it's nearly impossible to keep off the weight over the long term: "The amount of restriction required [to maintain that number] will make you so hungry that you’ll eat everything in sight—it’s survival instinct," Dr. Seltzer says. And since calorie restriction gradually slows your metabolism, your body will be less prepared to burn the foods you binge on, he adds. That could mean gaining more pounds than you lost in the first place.
HCG, or Human Chorionic Gonadotropin, is a hormone produced during pregnancy by the placenta after implantation, and doctors sometimes prescribe it for fertility issues. But this hormone has also gained popularity as a weight-loss supplement — and using it as such can be dangerous. In fact, the U.S. Food and Drug Administration (FDA) warns against purchasing over-the-counter hCG, as these supplement products are illegal. (34)
"Even though a smart diet is key, exercise can help boost your body's metabolism to shed fat. Through health care providers often recommend brisk walking or jogging, these exercises may not help you see the results you want. Instead, try interval training," shares Dr. Sean M. Wells, DPT, PT, OCS, ATC/L, CSCS Owner and PT, Naples Personal Training, LLC
"When going out for fast food, I used to get the large-size value meal. Now, I satisfy a craving by ordering just one item: a small order of fries or a six-piece box of chicken nuggets. So far, I've shaved off 16 pounds in seven weeks, and I'm on track to being thinner than my high school self for my 10-year reunion later this year." —Miranda Jarrell, Birmingham, AL
Very few diet plans outlive temporary fads and trends, and WW is definitely one of them. The diet company formerly known as Weight Watchers has kept up with the times by reinventing and rebranding itself as WW, which stands for “Weight Loss & Wellness.” While the company’s diet approach is still based on the Smart Points food-tracking system, it has recently incorporated meditations, audio workouts, food logging, Zero-Point foods, a redesigned app, and online support for a more holistic approach to dieting.
Also some research shows that the human body is primed to consume most of its calories during daylight hours. But the lifestyle is problematic for many: Because family meals and dinners with friends often are scheduled for after sunset, "people who try to stop eating after 7pm can’t do it every day for the rest of their lives," says Dr. Seltzer, who supports an alternative strategy: Eating a hearty meal at your regular dinnertime.
"I tell all of my celebrity and professional-athlete clients to get between 6 and 8 hours of sleep per night. Everyone is overly focused on food, water and exercise, all of which are extremely imperative to weight loss and optimal health. However, without proper sleep, all of these the other factors are null and void. When you don't get enough sleep, levels of the hormone leptin drop, which increases appetite. This surge in appetite makes comfort food more appealing, which can derail weight loss efforts." — Jay Cardiello, celebrity fitness and nutrition expert
