Whole foods include fruits, vegetables, beans, nuts, seeds, whole grains, eggs, seafood, chicken and so on. Food philosophies may differ around which of these foods to emphasize, but that’s okay, since the evidence shows that there isn’t a single best way to lose weight. The goal is to select an approach that feels sustainable to you. If you can easily live without pasta, perhaps a low-carb method centered around veggies and quality proteins, like seafood, chicken, and lean beef would be a good fit. Vegans and vegetarians can lose weight by choosing fruits, vegetables, whole grains and plant proteins. Nut lovers may do well shedding pounds with a Mediterranean-style menu. Whatever diet appeals to your appetite and way of life, focusing on whole foods is something that all plans promote.
Fermented foods: These enhance the function of good bacteria while inhibiting the growth of bad bacteria. Sauerkraut, kimchi, kefir, yogurt, tempeh, and miso all contain good amounts of probiotics, which help to increase good bacteria. Researchers have studied kimchi widely, and study results suggest that it has anti-obesity effects. Similarly, studies have shown that kefir may help to promote weight loss in overweight women.
“Starting slow and working your way up is better than overdoing it and giving up,” says Gagliardi. “I like the idea of attaching the new behavior of taking a walk to an existing behavior.” An easy way to approach it: Commit to going for a quick 10-minute walk after dinner, and slowly increase the time as you become more comfortable with daily movement.
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.
Falling short on zzz’s is also a surefire way to put your waistline in jeopardy. That’s because sleep deprivation knocks your hunger hormones out of whack, leading to an increase in ghrelin, which stimulates appetite, and a decrease in leptin, which signals when you are satiated. What’s more, research has shown that when you aren’t well-rested, you’re also more likely to reach for junk food (hello Ben & Jerry’s!)—and it may even become harder for you to build muscle mass.
Eat More Produce. Eating lots of low-calorie, high-volume fruits and vegetables crowds out other foods that are higher in fat and calories. Move the meat off the center of your plate and pile on the vegetables. Or try starting lunch or dinner with a vegetable salad or bowl of broth-based soup, suggests Barbara Rolls, PhD, author of The Volumetrics Eating Plan. The U.S. government's 2005 Dietary Guidelines suggest that adults get 7-13 cups of produce daily. Ward says that's not really so difficult: "Stock your kitchen with plenty of fruits and vegetables and at every meal and snack, include a few servings," she says. "Your diet will be enriched with vitamins, minerals, phytonutrients, fiber, and if you fill up on super-nutritious produce, you won't be reaching for the cookie jar."
