LeCheminant and his colleagues used a liquid form of very low energy diet (VLED) for weight loss. Subsequently, they randomized participants to receive a structured meal plan combined with either two-meal replacements or orlistat and physical activity. There was no significant difference in weight change between the groups during weight maintenance.[3]
Sure, there's your one friend who swears by the Taco Cleanse. And that other friend who ate nothing but broccoli soup for a month and dropped 20 pounds, found the love of her life, and got promoted at work. But before you start blending 80 stalks of broccoli into a cup or crunching your way through a crate of tacos, check out which diets are backed by science. Because don't you want to try one that will do the trick for you?
“Your body begins to work differently. This study proves that small amounts of nourishment throughout the day are better than the same amount of food concentrated in three big sittings. If we feed the body at regular intervals we send a signal to the body that it doesn’t have to store calories. Conversely, when we skip meals we send just the opposite signal for the body to store calories, creating a negative effect on the metabolism.” — Dr. Wayne Scott Andersen, co-founder and Medical Director at Take Shape For Life

Certain dieting and weight-loss resources may include over-the-counter products, commercial programs, and diets. Short-term weight-loss from a low calorie intake is possible with many of these methods. However, most weight-loss methods fail to contribute to healthy long-term weight maintenance, though some may provide helpful guidance regarding a healthy diet, positive lifestyle changes, and physical activity. The following information compares the strengths and weaknesses of several popular weight-loss products, programs, and diets, and also discusses alternatives to dieting that include healthy recommendations for effective weight-loss and long-term weight maintenance.


This book is terrible. I read this book during a slow day at the bookstore where I work, and I was disgusted. A book that suggests you can lose weight by making the giant lifestyle decision to eat a Big Mac instead of a Whopper is mostly likely authored by Satan. It also offers genius advice on which entree at Chipotle packs the least calories, as well as the healthiest menu item at TGI Friday's.


It is possible to do more in less time — at least when it comes to your workouts. By incorporating interval training — that means bursts of high-intensity moves — you’ll give your metabolism a huge boost, says Glenn Gaesser, Ph.D., director of the Kinesiology Program at the University of Virginia and author of The Spark. If you usually jog at a consistent pace, try adding a 30-second to one-minute sprint every five minutes, or, if you’re on a treadmill, change up the incline for one-minute intervals.
“(Users) could range from people with conditions such as elevated blood pressure to families looking to make healthier lunch choices for their kids at school,” said Huffman, who collaborated on FoodSwitch. “The app is designed to meet people where they are. … I understand that some people will still be eating (Froot Loops), so we’re trying to help people find alternatives closer to what their interested in.”

It has been shown that micronutrient dietary supplement consumption results in a lower body weight and resting metabolic rate in men and lower hunger level in females,[51] but there are no sufficient studies to assess their roles in preventing weight regain after weight loss. Only the Nachtigal cohort study revealed that long-term use of vitamins B6 and B12, and chromium were significantly associated with lower weight gain.[52]
Accessibility to foods: Some diet plans ship foods straight to your door, while others require you to shop for very particular ingredients. There are also a range of price points, with some diets costing substantially more than others. Consider whether the food allowed on a particular diet will fit into your budget and be relatively easy to find at grocery stores.
Next, you'll be asked about your goals. It's important to be realistic during this step. Your goal weight may be different than an ideal weight or a perfect weight. For example, you may want to weigh 120 pounds. But if you have struggled with your weight for most of your life and have never been lower than 150 pounds, then 120 may not be realistic at this time. Try to set a goal that you believe to be attainable. Once you reach your goal, you can always set a new one.

The OPTIFAST® program, which usually lasts 26 weeks, is a medically-supervised weight-management program that closely monitors and assesses progress towards better health and emotional well-being. The program utilizes a meal replacement plan that transitions to self-prepared ‘everyday’ meals, in conjunction with comprehensive patient education and support.


“When clients come to me, many of them have been through the diet wringer. They’ve tried every fad and gimmick and, of course, they’ve failed to maintain long-term success. The key to weight loss is to never feel like you’re on a diet, because diets don’t work. If you feel deprived, you will never make it past a few weeks. The only way to achieve long-term weight loss is to learn to appreciate food as fuel and slowly replaced processed food that cannot properly energize the body with real food that can. After a while this will become second nature and won’t feel like a daily struggle.” — Laura Burak, MS, RD, CDN

Now you know that your dinnertime TV show and dishware affect how much you eat—but did you know that your environment has an even greater impact on your noshing habits? The typical American buys and eats more than 80 percent of their food within five miles of their homes—a.k.a. your food radius—according to Brian Wansink, Ph.D., director of Cornell University's Food and Brand Lab. In his book, Slim By Design: Mindless Eating Solutions, Wansink talks about various studies he's done over the course of his research career that show how your food environment dictates your eating habits.
Talking with a health care professional about your weight is an important first step. Sometimes, health care professionals may not address issues such as healthy eating, physical activity, and weight during general office visits. You may need to raise these issues yourself. If you feel uneasy talking about your weight, bring your questions with you and practice talking about your concerns before your office visit. Aim to work with your health care professional to improve your health.
Realizing that eating unhealthy food is a bad habit, like smoking or biting your nails, will help you break the cycle. Going cold turkey on favorite snack foods isn't possible for everyone, and if you relapse and chow down on some chocolate, the first step is to forgive yourself for the lapse. Identify the times of day or the activities you engage in that tempt you to reach for the junk food. Being aware that it's going to happen will help you stave off the cravings and gives you the chance to substitute in a healthier option. Don't be afraid to let your friends and family know what you're doing so they can support and cheer you on, and so they can help you avoid cravings.
Even if you manage to meet your goal, it probably won’t be sustainable: “The amount of restriction required will make you so hungry that you’ll eat everything in sight—it’s survival instinct,” Dr. Seltzer says. What’s more, your body will be less prepared to burn the foods you binge on, since calorie restriction gradually slows your metabolism, he adds.
