No weight loss program rivals Weight Watchers' (Est. $20 and up per month) record of scientifically proven efficacy and enthusiastic expert and dieter endorsements. Its combination of in-person and/or online support and motivation, flexible points-based meal planning, and physical activity are hard to beat. There are no off-limit foods, and the program can be customized for any dietary need, making it a good choice for vegetarians, vegans and anyone who has a specific food allergy or intolerance. It emphasizes fresh fruits and vegetables by making them "free" foods -- in other words, foods that don't have to be portioned or tracked.
Everyone is different. How quickly you burn calories when you are not physically active can be very different from other people based on your specific genes, biology, and past. While scientists know that there are 3,500 calories in one pound, simply eating 500 fewer calories every day for a week (or 3,500 fewer calories in a week) does not always end in losing exactly one pound.
The South Beach Diet started as a book that was originally published in 2003, The South Beach Diet: The Delicious, Doctor-Designed, Foolproof Plan for Fast and Healthy Weight Loss (Est. $9). The book is still considered to be the best way to get information on the basic diet, but there are also many follow up books and cookbooks to supplement the original, as well as South Beach compliant recipes available around the Internet. The official South Beach Diet website is mostly fee-based.
If you've been trying to eat healthy for a long time, you know how quickly you get sick of chicken breasts and broccoli. Break out of your diet rut with the Middle Eastern diet. It's based on the same principles as the Mediterranean diet but with more of an emphasis on plant-based foods and a different flavor profile. With all the tasty and healthy spices, you'll never get bored of making dinner and you'll get all the same heart-healthy benefits as its geographical cousin's diet.

Your body needs a certain amount of essential vitamins and minerals to function properly. What happens when you don’t get enough of them? What happens when you eat too little food, or when the food you eat isn’t sufficiently nutritious? Perhaps our bodies catch on and reply by increasing hunger levels. After all – if we eat more, we increase the chances of consuming enough of whatever nutrient we are lacking.

Think cooking healthy meals is difficult and time-consuming? Think again. Annie Allen, a postsurgical nurse in Tampa Bay, Florida, let her freezer do half the work for her—and now she's down 52 pounds and runs about 10 races a year. "Frozen vegetables are as nutritious as fresh ones, and in minutes you have half of your meal prepared," she says. These frozen meals are also surprisingly healthy if you don't have time to mix and match one of your own.
"When we’re lacking in sleep, our body’s hormones get thrown off balance which can impact our hunger levels the next day. We all have two hormones that affect our appetite: ghrelin and leptin. When we don’t get enough sleep, our ghrelin levels (the hormone that makes us feel hungry) rise, and our leptin levels (the hormone that makes us feel full) drop. This means that when we’re awake, we tend to eat more but feel less satisfied. Try going to bed a little earlier than usual to avoid this imbalance and remember to remove any distractions that might prevent you from nodding off."
