A daily run or Spin class is great for your heart, but cardio workouts alone won't do much for your waist. "You need to do a combination of weights and cardiovascular training," says Sangeeta Kashyap, MD, an endocrinologist at Cleveland Clinic. Strength training increases muscle mass, which sets your body up to burn more fat. "Muscle burns more calories than fat, and therefore you naturally burn more calories throughout the day by having more muscle," says Kate Patton, a registered dietitian at Cleveland Clinic. Patton recommends 250 minutes of moderate-intensity exercise or 125 minutes of high-intensity exercise a week.
There seems to be a link between abdominal obesity and depression. There have been reports showing that cortisol, a stress hormone, is related to both depression and abdominal obesity. Some researchers suspect that people who are depressed may have higher levels of abdominal obesity because of elevated cortisol. More studies are needed to determine the underlying causes for weight gain among those who reported being depressed.
“Under normal conditions, humans absorb only about 80% of the nutrients from the food they eat,” says A. Roberto Frisancho, Ph.D., a weight-loss researcher at the University of Michigan. But, he says, when the body is deprived of nourishment, it becomes a super-efficient machine, pulling what nutrients it can from whatever food is consumed. Start eating again normally and your body may not catch up; instead it will continue to store food as fat.
Want to lose that belly fat? In your dreams! Seriously, though: a good night’s sleep is one of the best ways to get rid of that extra fat around your waist for good. Among the 60,000 women participating in the Nurses’ Health Study, those who snoozed for fewer than five hours a night were at the greatest risk of becoming obese and gaining 30 or more pounds over the course of the 16-year study period when compared to those who slept for seven or more hours.
Science backs these ideas up when it comes shedding belly fat: In one study published in The Journal of Nutrition, researchers had overweight men and women follow a high-protein diet (30 percent protein, 40 percent carbs, and 30 percent fat) or a high-carb diet (15 percent protein, 55 percent carbs, and 30 percent fat). After one year of weight loss and maintenance, they found that the high-protein group experienced a 21 percent greater weight loss and 27 percent greater body fat loss on average than the high-carb group.
Carrying too much belly fat is a big problem for many people nowadays, especially once they hit middle age. Aside from being unsightly, belly fat is the most dangerous type of body fat to carry, as it indicates a higher level of visceral fat around the internal organs. Therefore, in order to lead a healthy lifestyle and feel happy in your body, it's necessary to take serious action to eliminate body fat.
Once you’ve established a regular cardio routine, add two or three weight training sessions on nonconsecutive days to your weekly workouts; everyone naturally gains some fat as they age, but building muscle tone can significantly slow the production of belly fat. In a study conducted at the University of Minnesota, overweight women who did twice-weekly strength training routines that included eight to 10 exercises of major muscle groups, from biceps curls to leg presses, gained 67 percent less visceral fat over two years than women who didn’t do strength training regularly.
Don’t let extra hours lounging in bed stand between you and a flatter belly. While getting enough sleep can help boost your metabolic rate, sleeping in may undo any benefit you’d enjoy from catching a few extra winks. One study reveals that late sleepers who snoozed past 10:45 in the morning ate nearly 250 more calories over the course of the day, despite eating half as many fruits and vegetables as their early bird counterparts. Even worse, they chowed down on more salty, sugary, and trans fat-laden fast food than those who woke up earlier. If you happen to head out of the house early, you’re in for an additional metabolic boost; researchers at Northwestern University have found that people exposed to just a short period of early morning sunlight had lower BMIs than their late-waking counterparts.
While probiotics encourage the growth of good bacteria, prebiotics feed the ones you already have. When you eat prebiotic foods like onions and leeks, they produce butyrate, a metabolic wonder drug that improves insulin sensitivity and increases the amount of fat you burn, says Rafael Kellman, M.D., author of The Microbiome Diet. Now that it's summer, pop either on the grill to bring out their sweetness. Drizzle with olive oil, salt, and pepper and cook until golden.
