And as people get older they tend to become less active, which means you burn fewer calories all day long. Plus, you naturally lose muscle mass due to hormonal changes, which further drops your daily calorie-burn rate.

Eat polyunsaturated fats. While saturated fat leads to the body's retention of visceral fat, causing abdominal girth and excessive weight gain, studies have shown that a diet high in polyunsaturated fat helps promote the production of muscle mass instead of body fat.

5. Beware of buzzwords and marketing claims. Companies that make everything from soft drinks to processed foods may not always be telling the whole truth about how healthy their foods are, says Bowden. Their use of buzzwords like “organic” and “natural” might trip you up when you’re trying to make healthy choices. In a study published in 2014 in Food Studies: An Interdisciplinary Journal, researchers asked 318 college students to state whether they thought a food was healthy or unhealthy based on packaging images. When the image contained a health-food buzzword like “organic” or “whole grain,” participants rated the food as being healthier. Don’t judge a food by its packaging: Be sure to always read the nutrition label to get the whole story.
Tight deadlines, bills, your kids—whatever your source of stress, having too much of it may make it harder for you to drop unwanted pounds, especially from your middle. And it's not just because you tend to reach for high-fat, high-calorie fare when you're stressed, though that's part of it.

If a food product says it contains partially hydrogenated oils, you’re eating trans fat, which can increase your risk of heart disease, high cholesterol, and obesity with every bite. In fact, research conducted at Wake Forest University reveals that monkeys whose diets contained eight percent trans fat upped their body fat by 7.2 percent over a six-year study, while those who ate monounsaturated fat gained just a fraction of that amount.
