Follow the lead of top nutrition experts with this roundup of the five foods doctors swear by, inspired by my new book of healthy food swaps, Eat It to Beat It:
1. Greek yogurt
Gerard Mullin, M.D., director of the Johns Hopkins Integrative GI Nutrition Services and author of "The Inside Tract: Your Good Gut Guide to Great Digestive Health"
Greek yogurt for palatability, satiation and protein content. Yogurt is also great for feeding the good bugs that live in your intestine, which improves the health of your microbiome, the community of microorganisms that live in your body. More and more research is pointing to probiotics as an effective treatment for weight management and obesity. It's amazing that feeding the good bugs actually helps people lose weight. Organic, grass-fed yogurt is best because you are getting a better omega fatty acid profile. When animals are fed corn they produce dairy with more omega-6s, but grass-fed animals produce dairy with more healthy omega-3s.

Chickpeas. They are, of course, a nutritional powerhouse like most legumes. They are a good protein source, and I especially like turning to chickpeas for protein so I don't need to eat meat. They have figured in the human diet since the very dawn of civilization, so they are nice connection to our ancestral roots. And they figure as well in some of my favorite cuisines from the Middle East. I love good hummus!
3. Dark, leafy greens

For me the best food is dark greens, such as arugula, spinach, and lettuces. They are very low in calories, very high in nutrients, and can be prepared in a variety of ways that taste great -- many different types of salads, pasta dishes, lasagna, sandwiches, pesto, soups, or even a spinach pie! Locally in the summer is best and I always feel good about eating them, there's no downside.
Robert Lustig, M.D., M.S.L., director of the Weight Assessment for Teen and Child Health (WATCH) Program at the University of California, San Francisco, president of the nonprofit Institute for Responsible Nutrition, and author of "The Fat Chance Cookbook"
Eggs! They have lots of high quality protein, especially tryptophan. Protein is satiating, and also you spend more energy converting it to a metabolite that can be burned, which aids in weight management. Eggs got a bad rap in the 1980s because of the cholesterol in the yolk. But it does not raise the small dense LDL, which is the atherogenic particle [the one that forms plaques in your arteries]. Eggs are great by themselves, with many different ways of preparation, or they can be added to foods easily.
Taz Bhatia, M.D., assistant professor at Emory University in Preventive/Integrative Medicine, director of the Atlanta Center for Holistic and Integrative Medicine, and author of "What Doctors Eat"
I swear by avocados! The heart-healthy unsaturated fat in a delicious serving of avocado helps me stay full, which keeps me from snacking too much. Avocados are packed with vitamins C, K and B6 and they contain pre- and probiotics -- keeping my gut healthy!
STOP OVEREATING! Learn why everything from the color of your plates to the sounds in the room can influence your satiety.
