Because the diet isn’t as restrictive as a traditional vegan or vegetarian diet, it may be simpler to stick with — hence its No. 2 ranking in U.S. News & World Report’s Easiest Diets to Follow category. Because you’ll be eating meat some of the time, you may also be at a lower risk of the aforementioned nutrient deficiencies that vegetarians and vegans may face.
Five different Medifast plans plus one meal of lean protein and non-starchy vegetables will give you a loss of about 11 pounds in eight weeks, according to the company. Although these very low-calorie diet plans are effective in the short term, weight regain is a risk over the long haul. It also depends on processed foods and requires dieters to last through the hunger pangs. The plan is not recommended if you are pregnant, have type 1 diabetes, or have any of these other conditions. Here are 17 tips for getting over a weight-loss plateau.

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)
If you like eating meat and want to lose weight, you might be tempted to try this recent extreme diet fad that proponents have made some pretty outrageous claims about. One: that eating nothing but meat can cure you of autoimmune diseases. The problem is that there’s no good research to support that notion, or any other health claim, for that matter. Indeed, omitting foods known to be good for you — fruits and veggies among them — can lead to a bunch of unwanted side effects, including constipation and potentially dangerous nutrient deficiencies. Still, since you’re cutting out so many food groups, there’s a decent chance you’ll lose weight, experts say. Regardless of any possible benefits you might see, this restrictive approach is definitely one you’ll want to ask your doc about before you even consider diving in.
Vegetarians tend to be slimmer than omnivores, according to research. But you’ll have to have a lot of discipline and willpower to pull off a vegan diet. Support is out there—the American Diabetes Association gives its approval to the plan, and there are plenty of resources online such as the Vegetarian Resource Group if you need guidance. Following this rigid way of eating may mean could miss out on important nutrients such as vitamin B12 and calcium, but overall going vegan offers some powerful health benefits. You can expect to lose about two pounds a week. Check out the 13 things that happen to your body when you go vegan.
Lastly, to help you stay motivated I recommend you log your weight loss results so that you can gather an average. You will always have good weeks and bad weeks, but it’s the average that counts. Every weigh in (only weigh in once per week) write the pounds lost on your calendar. At the end of 8 weeks add up all the weight loss pounds and divide by 8 for your 8 week average. This will help you stay motivated and see your results. Anytime you have a bad week, think of your weight loss average and know this is all just part of the process.
Many diets, including Atkins and the keto diet, fit into this umbrella. A typical low-carb diet limits carbs to less than 60 g daily, but this can vary, according to the Mayo Clinic. (15) In a September 2015 review published in PLoS One, people following low-carb diets saw modest weight loss — although study authors note that long-term effects of the diet require further research.

There are many ways to do intermittent fasting — ranging from fasting for a number of hours each day up to an entire 24-hour fasting period one or two times a week. “If you're trying to kick a habit like eating late into the night, then stopping eating earlier in the evening and fasting overnight could be beneficial for you,” says Hultin. “There are many types of intermittent fasting, so ensuring you pick one that works for you and your lifestyle is important.”
For weight loss, you need to find the right balance of calories so that you lose at a rate of 1 to 2 pounds a week. Starvation diets that severely restrict caloric intake may help you lose weight faster, but you're losing water and muscle, not fat. Plus, when you eat too few calories, your body may hold onto fat as a means of protection against the starvation. This change in metabolism makes it even harder for you to lose the unwanted pounds.
Obviously, it’s still possible to lose weight on any diet – just eat fewer calories than you burn, right? The problem with this simplistic advice is that it ignores the elephant in the room: Hunger. Most people don’t like to “just eat less”, i.e. being hungry forever. That’s dieting for masochists. Sooner or later, a normal person will give up and eat, hence the prevalence of “yo-yo dieting”.
