Be choosy about carbs. You can decide which ones you eat, and how much. Look for those that are low on the glycemic index (for instance, asparagus is lower on the glycemic index than a potato) or lower in carbs per serving than others. Whole grains are better choices than processed items, because processing removes key nutrients such as fiber, iron, and B vitamins. They may be added back, such as in “enriched” bread.
Another thing that messes with circadian rhythms? The blue light of digital devices. “We have seen increasing scientific evidence that the more you use devices, the higher your risk of obesity,” says Gillespie. The reason is twofold: One, the more time you spend in front of a screen, the less time you’re running around and playing. But also, experts believe, the blue light these devices emit can disrupt your internal clock. One study found that using a blue light-emitting device before bed delayed the release of melatonin, a hormone responsible for sleep, and the effect carried over to the following night as well.
Tip #3: Limit your portions. Practice portion control with every meal and snack. When you learn to fill up on less (eating until you’re 80% full, for example), weight loss follows for most people. Going Wild and becoming fat-adapted comes with a natural suppression in your appetite. Recent research shows that eating less (and intermittent fasting – see below) can provide anti-aging and longevity benefits, as well.
It takes more than just crunches! We start to gain weight in our midsection when our cortisol levels spike. Stress is one of the primary culprits for high levels of cortisol secretion. When this happens cortisol breaks downs lean muscle (the type of tissue that burns calories most efficiently) and also holds on to fat storage in the abdominal region. That stress can even get WORSE with bad dieting; studies show that the stress caused by dieting can increase cortisol levels, making no change in belly fat even with calorie restriction. So how do you shape up? Incorporate these 6 things below and you will be on your way to a flatter belly in no time flat!
Probably. If you have overweight or obesity, your risk for many health problems is higher than that of women who are at a normal weight. Even a small amount of weight loss can lower your risk for or even prevent health problems like diabetes and heart disease. Calculate your body mass index (BMI) to see whether you’re at a healthy weight. If you have overweight or obesity, start by making small changes to your eating habits and getting more physical activity.

Swapping out unhealthy foods for nutritious ones gives you benefits beyond just losing weight. "I cleaned up my diet, swapping deli sandwiches with high-sodium meat and mayo for Tupperware containers or big butter-lettuce salads topped with carrots, walnuts, feta, and homemade dressing," says Jennifer Lasher, who lost 75 pounds. "I found that ditching processed foods left me with more energy, a clear head, and better skin, too."
If you follow food trends, you might think you have to fall in love with cauliflower and kale to reap all the rewards that veggies offer, but that isn’t the case. Be it broccoli, sweet potatoes, carrots, red peppers, cabbage, spinach, or any other vegetable, the idea is to eat a variety of them and find plenty of ways to enjoy their goodness. So if you just can’t stomach steamed Brussels sprouts, try them roasted, or give sautéed Brussels sprouts a try. If raw zucchini isn’t your thing, see if you like it spiralized into noodles or grilled on a grill pan.
And then below the subcutaneous fat lies visceral fat. Visceral fat is the deep-lying belly fat that surrounds internal organs and releases inflammatory compounds that negatively affect your system. It can lead to an increased risk of metabolic syndrome, cardiovascular disease, and type 2 diabetes. Women with a lot of belly fat are more likely to develop breast cancer or need gallbladder surgery. 
Additionally, protein raises the rate of your metabolism and assists in retaining of muscle mass when you are losing weight. Studies have shown that individuals who consume a lot of protein have less fat in the abdomen than those who consume a diet low in protein. Try including excellent sources of protein during every meal like beans, whey protein, dairy, eggs, fish, and meat.
Want a flatter stomach? Look in your glass—milk and soda are two major causes of tummy inflation. Approximately 65 percent of the human population has a reduced ability to digest lactose after infancy, which means that your glass of warm milk before bed may be the reason you wake up with too-tight pajamas. And when it comes to soda, both regular and diet are belly busters both from the sweeteners used and the carbonation. Try eliminating these from your diet and see if it helps flatten your tummy.
