This high-protein, low-carbohydrate, diet plan claims you can lose nine pounds in two weeks. South Beach is different from other low-carb diets because it incorporates more unsaturated fats, such as those in olive oil and avocados, rather than saturated fats. On the downside, the cost can add up quickly if you’re buying the meals, and the first few phases of the diet don’t allow for eating out (or ordering in). No matter which diet plan you choose, avoid these 20 foods that are never worth the calories.

Cutting out food groups is not the healthiest weight loss solution. “When you eliminate either fats or carbohydrates, you’re probably eating way too much of what’s left over,” says Kristin Kirkpatrick, MS, RD, manager of wellness nutrition services at the Cleveland Clinic Wellness Institute. For example, if you cut out fat, you could overdo it on carbohydrates or vice versa. Instead, Kirkpatrick recommends balancing your meals and having one whole grain carbohydrate at each meal and opting for low-fat dairy products and lean meats. Here is the worst diet advice nutritionists have ever heard.


The idea is that the fasting induces mild stress to the cells in your body, helping them become better at coping with such stress and possibly helping your body grow stronger.

The 3 Day Diet is low calorie, but it certainly is not low-fat, low-salt, or low cholesterol, so it is not a healthy option for most people with certain medical conditions such as diabetes, hypertension, heart disease, and high cholesterol. If you are overweight, weight loss is key to managing these conditions. But it should be a healthy and sustainable weight loss that includes healthy nutrition and exercise.

A favorite of health experts, the DASH diet has the primary goal of limiting sodium and lowering blood pressure, but the bonus is losing weight by shifting to a healthier way of eating. The DASH diet plan advocates building meals around fruits, veggies, whole grains, lean meats, and healthy fats. Evidence demonstrates that the approach is effective, especially when you add in regular exercise. You can improve your results, suggests some research, by adding more lean protein to the diet. This is one of the healthier approaches, and it’s easy to adapt to your needs, though the salt restrictions make eating out tough. Looking for another way?

Fiola Sowemimo, MD, board-certified in internal and bariatric medicine, says that the quality and quantity of food you eat is only half of the weight loss equation. “Regardless of which diet you choose, when you eat is important too,” Dr. Sowemimo says. Starving during the day and ignoring hunger could lead to bingeing later, she says. Plus, Wendy Bazilian, DrPH, RD, adds that the peaks and valleys of hunger throughout the day could make it more difficult to manage cravings. Eating regular meals at regular times could actually help normalize your metabolism, according to Dr. Bazilian.
