This easy a.m. ritual works on two levels. First, a recent study found that exposure to sunlight in between the hours of 8 am and noon reduced your risk of weight gain regardless of activity level, caloric intake, or age. Researchers speculate that the morning light synchronizes your metabolism and undercuts your fat genes. And burning calories before you eat means you’re exercising in a fasted state—the energy you burn comes right from your fat stores, instead of the food you ate. But what really stunned Martha was the improvement in her heart health. Before starting Zero Belly Diet, Martha’s heart rate would typically soar to 112 beats per minute (bpm) within moments of starting her exercise bike workout. “After the first week and a half I could not raise my heart rate over 96 bpm with the same workout. It was great to see change in the mirror, and even better to know good things were happening that I couldn’t even see.”
Leafy Greens – Help you feel satisfied longer, boost your metabolism and turn off your hunger receptors. You will eat less and lose more belly fat just by increasing your leafy greens!

Real talk: It could take weeks or months to see the metabolic effects of exercise on the scale, and even then, building muscle, which is denser than body fat, could lead to weight gain. "Do what you like because it’s good for you," Dr. Seltzer says, noting the way exercise is awesome for your heart, mental health, and more—and that not all measure of progress can be seen on the scale.
The face has a dual dial system, with a sub-dial that keeps track of your activity throughout the day. At the top of the dial is a surprisingly readable OLED screen that displays heart rate during workouts and scrolls through app notifications. The whole package is housed in an attractive stainless steel case, with a band reminiscent of Apple Watch's sport bands.
In my informal testing, the heart rate sensor isn't quite as snappy as the Fenix 5 Plus or Apple Watch 4's sensors, but it's accurate enough that I'm confident in its readings. Like those devices, the Instinct can also display notifications from your phone. Though if you're used to being able to do stuff with your notifications like I am, suddenly not being able to do anything with them can take some getting used to.
Stress wreaks havoc on every part of your body, and can lead to breakouts, joint pain, headaches, and yes, even excess belly fat. That’s because when you’re stressed, your body pumps out extra cortisol, that not-so-great hormone you keep hearing about. Studies show that cortisol not only spikes your appetite, but may also redistribute body fat to your belly area, according to a review published in the journal Obesity.
