2. Go to sleep earlier: A study in BMC Public Health found that people who racked up insufficient sleep on the reg were more likely to have a higher BMI. Meanwhile, researchers from the University of Chicago found that sleep loss causes decreased glucose tolerance and insulin sensitivity (those processes that cause your body to shuttle nutrients into fat cells instead of muscle cells) as well as elevated levels of ghrelin—the hunger hormone—and cortisol, the stress hormone that encourages your body to store fat. What’s more, the less you sleep, the less testosterone your body is able to produce. In short, skimping on sleep messes with all the hormones that help extra fat off your body—so hit the hay already. Shoot for at least 7 hours a night, more if you’re training hard because your body needs more time to repair and rest.
The study authors believe that sleep deprivation can cause your body to produce extra hunger hormones (like ghrelin) and fewer satiety hormones (like leptin). This means you’ll feel hungrier and have a harder time controlling your cravings once they hit. Most adults should aim for at least 7 to 9 hours of shuteye per night, per the National Sleep Foundation’s recommendations.
"When going out for fast food, I used to get the large-size value meal. Now, I satisfy a craving by ordering just one item: a small order of fries or a six-piece box of chicken nuggets. So far, I've shaved off 16 pounds in seven weeks, and I'm on track to being thinner than my high school self for my 10-year reunion later this year." —Miranda Jarrell, Birmingham, AL
Spreading the same amount of calories out over the course of your day so that you’re eating within an hour of waking up and then every four to six hours will jumpstart your metabolism, kicking off your calorie burn, and keep it going at a steady pace all day long, Crandall says. This works for a lot of people by keeping blood sugar levels steady, preventing the surges and plunges that can lead to ravenous hunger and overeating. It also keeps you from feeling deprived.
Fighting constantly with your S.O.? It’s time to address your issues head-on. "Research has shown that cortisol, the hormone that's released during stressful activity, is linked to fat storage,” says Gina Guddet, couples counselor and co-author of Love Metabolism. “And poor communication between couples is the most common type of stress that you tend to experience."
Cross-training is important for a few reasons: First off, it makes you a stronger runner and reduces your risk of injury. “Running is only hard on your joints if you don’t have the muscle to support them,” Rubin says. Secondly, lifting will help you lose weight. “The more lean muscle mass you have, the more calories you’ll burn at rest,” she says. That's right, more muscle means more burned calories when you're just sitting around. To get started, try these 10 essential strength exercises for runners.
The 3 branched chain amino acids are leucine, isoleucine, and valine. It has long been known that these three amino acids are great for preventing muscle tissue breakdown and building new muscle tissue. What most people do not know is that BCAA supplementation can increase fatty acid utilization for energy by decreasing protein breakdown for energy use.
It’s impossible to target belly fat specifically when you diet. But losing weight overall will help shrink your waistline; more importantly, it will help reduce the dangerous layer of visceral fat, a type of fat within the abdominal cavity that you can’t see but that heightens health risks, says Kerry Stewart, Ed.D., director of Clinical and Research Physiology at Johns Hopkins.
Have Protein at Every Meal and Snack. Adding a source of lean or low-fat protein to each meal and snack will help keep you feeling full longer so you're less likely to overeat. Try low-fat yogurt, small portion of nuts, peanut butter, eggs, beans, or lean meats. Experts also recommend eating small, frequent meals and snacks (every 3-4 hours), to keep your blood sugar levels steady and to avoid overindulging.
Nuts are an excellent way to curb hunger between meals. They're high in protein, fiber, and heart-healthy fats. Studies suggest nuts can promote weight loss and improve cholesterol levels when eaten in moderation. They're also rich in calories, so limit your portions. If you have to get them out of their shell, you'll slow down and not eat as much.
At its core, burning fat comes down to the process of lipolysis—the breaking down of fat lipids, explains Seedman. This happens in the mitochondria of the muscles, or the powerhouses of the cells, responsible for generating the energy our cells need to do their jobs. Exercise has been shown to improve mitochondria function, which then promotes fat breakdown, Seedman adds. Plus, working out helps regulate pretty much all the hormones that optimize fat loss.
