You know you're supposed to eat more protein to lose weight, but you might not know exactly why. Well, it actually has to do with how your body handles insulin. "Your body starts to produce more insulin as you age, since your muscle and fat cells aren't responding to it properly," explains Louis Aronne, M.D., director of the obesity clinic at Cornell University.
As you get older, your body changes how it gains and loses weight. Both men and women experience a declining metabolic rate, or the number of calories the body needs to function normally. On top of that, women have to deal with menopause. "If women gain weight after menopause, it's more likely to be in their bellies," says Michael Jensen, MD, professor of medicine in the Mayo Clinic's endocrinology division. In menopause, production of the hormones estrogen and progesterone slows down. Meanwhile, testosterone levels also start to drop, but at a slower rate. This shift in hormones causes women to hold onto weight in their bellies. The good news: you can fight this process. Read on.
You know that friend who casually chats about the healthy meals she whips up for her fam like it's NBD? She's planning ahead, and you should be, too. "When you plan an entire week of dinner in advance, you're way less likely to go off course and indulge in foods that aren't good for you," says Salzman. (Her weekly dinner planner is a favorite for Elizabeth Berkley when she needs food-spo.) Science backs her up, as those who spend more time prepping food at home eat at least eight servings of fruit and 13 servings of veggies each week, while those who don't tend to eat only six servings of fruit and just under 11 servings of vegetables. So get into a routine and, after weekly grocery shopping, kick the kids out for playtime with Dad so you can knock out as much work ahead of time as possible — cleaning and slicing veggies, portioning out chicken breasts for each meal, etc. Come dinnertime, there'll be barely any work before food is on the table.
Include physical activity in your daily routine. For most healthy adults, the Department of Health and Human Services recommends moderate aerobic activity, such as brisk walking, for at least 150 minutes a week or vigorous aerobic activity, such as jogging, for at least 75 minutes a week. If you use a step counter, remember that it takes an average of 10,000 steps per day to prevent weight gain. Some studies indicate it might take 15,000 steps per day to prevent the regain of weight after significant weight loss.
"Your body needs a healthy balance of exercise and rest. Doing too much prevents the body from shifting excess fat. Exercising without rest can impact our levels of the steroid hormone cortisol and cause an increase of stubborn fat stored in the belly. Not allowing your body to recover can increase the risk of injury too, so make sure you factor in rest days to your plan."
You don’t have to be the next Usain Bolt in the making to enjoy some serious belly-slimming results from hitting the track from time to time. Even a moderate-rate jog a few times a week can blast through that belly fat; in fact, a study conducted at Duke University Medical Center found that, over the course of an eight-month study, overweight adult study subjects who jogged 12 miles a week lost the most belly fat and burned 67 percent more calories than participants who did an equivalent amount of resistance exercise, or a combination of cardio and resistance work.
