Lifestyle changes: Many people struggle with weight not only because of their eating and exercise habits, but because their lifestyles are stressful or exhausting, which makes losing weight more difficult. A plan that emphasizes quality sleep, stress control, and other tools that contribute to fat loss can help you lose the pounds and keep them off long term.
“A lot of people think the foundation of a paleo diet is high-fat meat, but I suggest that it’s vegetables,” says Hultin. The concept is to eat only foods — including meat, fish, poultry, eggs, fruits, and vegetables — that would have been available to our Paleolithic ancestors. This means grains, dairy, legumes, added sugar, and salt are all no-no’s.
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.
If you’ve been eating fast food for years, get real about your approach: You’re probably not going to stick to an organic, gluten-free, paleo overhaul for very long. "You want to change as little as possible to create calorie deficit," says Dr. Seltzer, who insists the best way to support sustainable weight loss is to incorporate small changes into existing habits. So instead of giving up your daily BLT bagels in favor of an egg-white wrap, try ordering your sandwich on a lighter English muffin. Or say you eat a snack bar every afternoon: Swap your 300-calorie bar for a 150-calorie alternative. "Your brain will feel the same way about it, so you won’t feel deprived," he says.
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.
You're probably eating more sugar than you realize. The average person takes in 22 teaspoons of sugar a day—more than three times the amount suggested by the American Heart Association. The white stuff is added to foods that don't even taste sweet, such as breads, condiments, and sauces. Read food labels carefully: ingredients are listed in the order of how much is in the food, so if sugar is near the top, put it back on the shelf.
Rounding out the top three for best weight loss programs on the U.S. News and World Report 2016 rankings, the Biggest Loser meal plan uses a pyramid system with fruits and veggies setting the foundation. Simple tenets back the plan: for example, being mindful of portion control, keeping a food diary, and exercising regularly. So, yes, work will be involved, but the plan is sustainable in the long-term and a likely way to shed pounds.
