Few things are more discouraging to someone on a weight-loss plan than the oft-cited statistic that 95% of people who lose weight will regain it within a few years. The difficulty in sticking with a long-term weight-maintenance plan is one of the main reasons that weight-loss programs fail. To uncover clues to successful weight loss, researchers have been collecting information on people who have lost weight and successfully kept it off for many years. This project, known as the National Weight Control Registry (NWCR), records what these people did to achieve their goals.
Created in 2003 by cardiologist Arthur Agatston, this low-carb diet features three phases. The first phase is the most restrictive, limiting carbs such as potatoes and rice. Each subsequent phase becomes more lenient, and the diet emphasizes lean protein, unsaturated fats, and low-glycemic carbs such as nonstarchy vegetables. South Beach promotes lasting lifestyle changes, according to the Mayo Clinic. (21)
Your body needs a certain amount of essential vitamins and minerals to function properly. What happens when you don’t get enough of them? What happens when you eat too little food, or when the food you eat isn’t sufficiently nutritious? Perhaps our bodies catch on and reply by increasing hunger levels. After all – if we eat more, we increase the chances of consuming enough of whatever nutrient we are lacking.
To encourage ketone production, the amount of insulin in your bloodstream must be low. The lower your insulin, the higher your ketone production. And when you have a well-controlled, sufficiently large amount of ketones in your blood, it’s basically proof that your insulin is very low – and therefore, that you’re enjoying the maximum effect of your low-carbohydrate diet. That’s what’s called optimal ketosis.
Some men can lose up to 5 lbs. per week, says Juge, if they follow the diet strictly. He recommends striving for a weekly 2- to 3-lb. loss for more lasting effects. "That way it's not such a drastic change and you'll be less likely to put all the weight back on when the diet's done," he adds. Weigh yourself naked just once per week, at the same time, preferably on the same scale. That way it'll be as accurate as possible.
Make sure that the diet has been studied extensively for safety — and discuss any changes with your physician or registered dietitian before beginning a new diet. (If you don’t have a dietitian, find one in your area at the Academy of Nutrition and Dietetics website.) And do a self-check to ensure the diet fits with your own values and preferences.
We don’t always eat simply to satisfy hunger. All too often, we turn to food when we’re stressed or anxious, which can wreck any diet and pack on the pounds. Do you eat when you’re worried, bored, or lonely? Do you snack in front of the TV at the end of a stressful day? Recognizing your emotional eating triggers can make all the difference in your weight-loss efforts. If you eat when you’re:
This diet was most likely not developed by nutrition experts. One web site that offers the diet includes this warning: “Neither the staff nor management of 3 Day Diets are experienced, licensed, or knowledgeable to judge or recommend the validity or safety of this diet. We do not necessarily endorse this diet and recommend that before trying this or any other diet to consult a physician or licensed medical practitioner. Use at your own risk.”
Fitness and diet guidelines are also a good way of educating clients about the benefits of living a healthy lifestyle. Armed with this information, clients can have a better appreciation of the diet program and how this can help them achieve their desired results. Online resources, guidelines and consultants give clients a better understanding of the diet program and increases compliance.
The scale is not necessarily your friend. You may want to lose fat – but the scale measures muscles, bone and internal organs as well. Gaining muscle is a good thing. Thus weight or BMI are imperfect ways to measure your progress. This is especially true if you’re just coming off a long period of semi-starvation (calorie counting), as your body may want to restore lost muscles etc. Starting weight training and gaining muscle can also hide your fat loss.
“This is a great way of eating that I highly recommend to many clients, and I even model in my own life,” says Elizabeth Shaw, RDN, who is in private practice in San Diego and is the co-author of Fertility Foods Cookbook. “Since the premise of the diet is designed to help people who have high blood pressure, low-sodium foods are recommended. But considering that most Americans exceed their daily sodium levels anyway, it’s not surprising that dietitians recommend this style of eating for treating many different conditions, such as heart disease and obesity.”
This high-protein, fat-rich plan claims you will lose up to 15 pounds in two weeks, but the unhealthy fat content drops the diet’s ranking. Similar to the ketogenic diet, the idea is that by severely restricting your carb intake, your body will have to burn fat for energy. Atkins has a decent amount of short-term research to support the premise, but the results are mixed. The American Heart Association links saturated fats—prevalent in this plan—to heart disease. Other negatives for Atkins are that it’s tough to sustain, and you’ll miss out on fiber and other nutrients in complex carbohydrates like whole grains.

In other words? "Drinking makes you more likely to eat sh*t," Dr. Seltzer says, referring to drunk foods. At the same time, he stops short of asking patients to quit alcohol cold-turkey to lose weight. Plus, research suggests you don’t have to, as long as your intake is moderate—i.e., less than about a drink a day. "If you drink a glass of wine every night and notice you eat more afterward, eat less early to account for this," he says. "Or, if you’re drinking four glasses of wine a week, drink three instead so you’ll won’t feel such a big difference."

Real talk: It could take weeks or months to see the metabolic effects of exercise on the scale, and even then, building muscle, which is denser than body fat, could lead to weight gain. "Do what you like because it’s good for you," Dr. Seltzer says, noting the way exercise is awesome for your heart, mental health, and more—and that not all measure of progress can be seen on the scale.
Keeping a food journal could help you reach your weight loss goals. Best Health reports a recent study found participants who kept daily food records lost twice as much weight as those who kept no records. Colleen Cannon, a clinical psychologist in Canada who specializes in helping people deal with the emotional side of eating, says the act of writing down what we eat helps us become more aware.
You will likely lose weight on any diet if you eat less than 910 calories a day. But losing 10 pounds in 3 days is both unlikely and unhealthy. To lose just 1 pound of body fat, you need to reduce your daily calories by about 500 a day for a whole week. That’s giving up 3,500 calories over the course of 7 days. To lose 10 pounds in 3 days would mean decreasing your calorie intake by 35,000 calories in just 3 days! The Academy of Nutrition and Dietetics recommends a slow and steady weight loss of no more than 1/2 to 1 pound a week. Otherwise you are losing muscle and water, as well as weakening your bones. You also are much more likely to gain it all back.

It could be beneficial for your health and your weight loss goals to drink more water and less alcohol. Dr. Bazilian says that alcohol doesn’t have to necessarily be avoided altogether. but you should think if and where alcohol fits in the context of your overall health goals. “Aside from calories, alcohol doesn’t offer much by way of nutrition, so it’s at minimum an important decision to have going into any weight-loss program for yourself whether, how often, what type and how much may or may not fit in your timeline and goals,” she says. Alcohol also reduces inhibitions sometimes making it more challenging to make healthy eating choices, according to Dr. Bazilian. And alcohol may negatively impact sleep which plays a role in healthy metabolism, she adds. 


Open up a big bag of baby carrots and dip them into your freshly made no-oil-added, no-salt-added hummus. Simply whip up in your food processor a can of no-salt-added chickpeas/garbanzo beans, fresh tomatoes, lemon juice, garlic, a jalapeno pepper (if you like your hummus hot and spicy), and fresh herbs like cilantro and dill. Add a little water, if necessary, until the desired consistency is achieved.
Try to do at least 30 minutes of moderate-intensity aerobic exercise, such as a fast walk or a low-impact aerobic class, five days a week. Additionally, you want to work out all the major muscle groups with strength-training exercises, such as lifting weights or using a resistance band, for 30 minutes two days a week. As you lose weight and your fitness level improves, you may want to increase your exercise to up to 60 minutes a day to burn more calories, but with your doctor's permission and supervision.
While 1,200 may be the right number for some, it can be super restrictive for others, says Jaclyn London, MS, RD, CDN, Nutrition Director at the Good Housekeeping Institute. Try basing your meals and snacks off this plan and double up on veggies at any opportunity — more fruit at snack time works too! You can also add an extra ounce or two of protein at all meals if you find yourself feeling hungry. The combo of fiber from produce and lean protein makes this an adaptable strategy that’ll help you lose weight safely — one meal (and snack) at a time!
