An advisory committee to the government's 2010 Dietary Guidelines concluded that evidence overwhelmingly shows that diets based on the glycemic index do slightly or no better at weight loss than other types and aren't markedly superior at keeping off pounds already lost. In 2009, the independent, nonprofit Cochrane Collaboration reviewed six small, randomized controlled trials of low-GI diets tested over periods from several months to a year. Overall, low-GI dieters lost about 2 more pounds than comparison diets on average. Researchers found similar results in a study published in the New England Journal of Medicine in 2010. They examined weight-loss maintenance of 773 overweight adults on high- and low-GI diets. After 26 weeks, the low-GI dieters had regained 2 pounds less on average than their high-GI counterparts had.
When it comes to food, there is evidence that men and women’s brains are wired differently. In a study published in the January 2009 issue of the Proceedings of the National Academy of Sciences, even though women said they weren’t hungry when asked to smell, taste, and observe treats such as pizza, cinnamon buns and chocolate cake, brain scans showed activity in the regions that control the drive to eat (not the case for men).
It is also important to refrain from eating chocolate and from drinking caffeinated beverages and alcohol (wine included), as these have negative effects on female hormones during menopause. It is enough to do this temporarily, improvements are normally quick to show. The ketogenic diet asks us to make a mental shift – to let go of the conviction that all fat is bad and, well, fattening. It isn’t so.
Sometimes, you might need an external motivator—like a race or a competition—to keep you on track. After a slow start to her slimdown, Maribel Contreras decided to sign up for a 12-week body transformation contest at her gym. She swapped out her fast-food trips for healthy homemade meals and revved up her workouts, which ultimately helped her win the competition. She now maintains a 77-pounds-lighter frame.
What's more trustworthy than a diet built by experts from the Mayo Clinic? Created by doctors, nutritionists, and all-star chefs, the plan has a few phases: In the first, you should lose 6 to 10 pounds in two weeks.

Marie Rose Yardis, 38, wishes she'd known from the start that there's no need to go as low as possible with calories. "I worked with a trainer that told me I had to increase calories to support my workouts," she says. "It felt impossible, but I did it and lost a good amount of weight as a result! We all see in the media that cutting calories equals a smaller body. But when you are combining your nutrition habits with tough training sessions, you can really do a disservice to your body by underfeeding it!"

Switch to Lighter Alternatives. Whenever you can, use the low-fat versions of salad dressings, mayonnaise, dairy products, and other products. "You can trim calories effortlessly if you use low-fat and lighter products, and if the product is mixed in with other ingredients, no one will ever notice," says Magee. More smart substitutions: Use salsa or hummus as a dip; spread sandwiches with mustard instead of mayo; eat plain roasted sweet potatoes instead of loaded white potatoes; use skim milk instead of cream in your coffee; hold the cheese on sandwiches; and use a little vinaigrette on your salad instead of piling on the creamy dressing.
Whereas many beverages can increase your waistline (see above), there is one that is guaranteed to trim your tummy: water. Drinking plain ol’ H2O works because staying fully hydrated tells your body it’s okay to release any extra water it’s retaining, decreasing the accompanying bloat. Plus, drinking water has been proven to reduce cravings for sweets, lower your appetite, and help you feel satiated faster. Here 9 more ways to bust belly fat in a single day!
"Crash diets (dramatically cutting down how much you eat) might help you to lose a few pounds at first, but they’re hard to sustain and won’t help you keep the weight off. It might seem like a quick and easy option, but eating too few calories can actually do more harm than good. If your calorie intake dips too low, your body could go into starvation mode. This will slow down your metabolism, making it harder for your body to lose weight. Make sensible, healthy changes to your lifestyle that you can stick to and avoid the fad diets."
