Blood vessels (veh-suls): The system of flexible tubes—arteries, capillaries and veins—that carries blood through the body. Oxygen and nutrients are delivered by arteries to tiny, thin-walled capillaries that feed them to cells and pick up waste material, including carbon dioxide. Capillaries pass the waste to veins, which take the blood back to the heart and lungs, where carbon dioxide is let out through your breath as you exhale.
Switch things up. Any physical activity that takes a bit of effort will help you get fit, but it's important to remember that variety is the spice of life—and of physical fitness! More importantly, as your body gets comfortable performing a certain activity, it learns to do it more efficiently, making it easy for you to plateau in your workouts. Keep both your body and your mind guessing by enjoying a diversity of activities and having fun.
"Feeling stressed can wreak havoc on our bodies. It can cause our body to produce the steroid hormone cortisol, which can make you crave sugary foods that provide instant energy and pleasure. Short-term bursts of cortisol are necessary to help us cope with immediate danger, but our body will also release this hormone if we’re feeling stressed or anxious. When our cortisol levels are high for a long amount of time, it can increase the amount of fat you hold in your belly."
Women who wake up and go to bed at the same time each day have lower levels of body fat, according to a study of more than 300 women from Brigham Young University in Utah. Chaotic sleep habits cause your internal clock to go haywire, which in turn causes your body to secrete fat-storing hormones like cortisol. The sweet spot? Try not to stray an hour from your usual sleep pattern, the study authors say. More than a 90-minute difference in sleep and wake times were linked to more body fat. (Tossing and turning?

Most people who want to lose weight have more than 12 pounds to lose. That’s why even the best weight loss drug in the world can only be an optional complement to other treatment. That’s why this piece of advice is number 18 out of 18. It may be a helpful addition for some people, but the advice higher on the list is what can make the biggest difference, by far.
Here's something else most people probably don't know: Fidgeting is good for you. It's considered a nonexercise physical activity, and it's an important way to burn energy. You get more health benefits if, in addition to exercising, you are a more fidgety, more active person the rest of the day. This means gesturing while you're talking, tapping your foot, just moving around.
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. It's also due to the stress hormone cortisol, which may increase the amount of fat your body clings to and enlarge your fat cells. Higher levels of cortisol have been linked to more visceral fat.
Insulin (in-suh-lin): A hormone made by the cells in your pancreas. Insulin helps your body store the glucose (sugar) from your meals. If you have diabetes and your pancreas is unable to make enough of this hormone, you may be prescribed medicines to help your liver make more or make your muscles more sensitive to the available insulin. If these medicines are not enough, you may be prescribed insulin shots.
Clean your house vigorously. You'd be surprised how physically taxing housework is: dusting your shelves, cleaning your toilets, doing the dishes, mowing the lawn, pulling weeds, vacuuming and sweeping, picking up the house, and cleaning the garage will definitely give you a workout. Making yourself and your family clean parts of your house on a regular basis will not only create a better environment for you to live in, but also make burning calories, staying flexible, and keeping in shape a much simpler process.

Everyone’s body is different when it comes to digesting some gas-forming foods, but there are a few you should be wary of: It’s best to avoid beans and cruciferous veggies (think cabbage, Brussels sprouts, cauliflower, and broccoli) for a couple of days if you want to look slimmer. Choose lean proteins like chicken and fish or, if you’re vegetarian, go for small amounts of nuts and seeds for protein. Pair with non-gassy vegetables like asparagus, spinach, and cucumber to help prevent bloat.


Indulging in delicious food is a core principle of Zero Belly Diet. It was the balanced, “zero sacrifice” approach that helped test panelist Jennie Joshi finally lose her pregnancy weight. In just over a month on Zero Belly Diet, Jennie lost 11 pounds, “and the pregnancy pooch is leaving!” she said. “I couldn’t believe I was indulging in dark chocolate—and finally getting results! It’s a lifestyle, not a diet. It’s easy to stick with, and it makes sense.”
It seems counterintuitive to drink lots of water when you’re looking to lose weight fast—especially water weight—but staying hydrated is one of the most important steps you can take to lose weight. People often mistake thirst for hunger, so staying hydrated allows you to be more in touch with the times when you are actually hungry, rather than just thirsty. Plus, a lot of good things happen to your body when you drink enough fluids.
The biggest reason we can’t stick to our workouts? No time. Trying to squeeze a trip to the gym, with a shower and change of clothes, into a hectic schedule—especially around the holidays—can make even the most dedicated fitness buff into someone, well, less buff. But scientists in New Zealand recently found that men and women who engaged in three 10-minute exercise “hors d’oeuvres” before breakfast, lunch and dinner saw lowered blood glucose levels—a fat-busting benefit these folks showed all day long!
Protein serves a dual role in helping you trim down belly fat by increasing muscle mass and metabolism, while also helping stave off hunger. Research shows that a higher-protein diet increases thermogenesis, which means you burn more calories. Further, eating protein leads to an increased feeling of satisfaction after the meal, often causing you to eat fewer calories later in the day. These High-Protein Breakfast Tacos are the perfect way to start your morning and will keep you feeling full until lunch.
That’s exactly what happened when I shared Zero Belly Diet with a test panel of more than 500 people, some of whom lost as much as 16 pounds in just 14 days, and up to 3 inches off their waist. The secret to Zero Belly Diet is the new science of nutritional genetics, the study of how our genes are turned on and off by the foods we eat. Simply making a handful of tweaks to your diet and lifestyle can help improve your gut health, dampen inflammation, turn off your fat genes and start your body shedding fat—in particular, belly fat—almost automatically. Read on to find out how—and strip away belly fat and lose up to 16 pounds in just two weeks—while eating the foods you love—with Zero Belly Diet, available now!
"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."
Rather than a long and low-intensity cardio workout, try the HIIT method of cardio: intense, fast-paced intervals that leave you completely exhausted after only a 20- to 30-minute session. This form of cardio training increases the afterburn effect, allowing your body to continue burning calories long after your workout is over. You can rotate between 30 seconds of your favorite exercises, with rest in between, as long as they work different muscle groups—such as squats, push-ups and kettlebell swings.
The conclusion? Intermittent fasting was just as effective for weight loss as daily calorie restriction. So if you struggle with daily food restriction, fasting might be an easier way to dial back the amount you’re eating without feeling completely deprived. Read more in-depth about how intermittent fasting works (and if you’ll be able to stick to it) here.

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.
