"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."
Too little sleep or too much sleep can throw your stress and regulatory hormones out of whack, and may lead to weight gain. A single night of sleep deprivation can increase levels of ghrelin (a hormone that promotes hunger), making you more likely to overeat the next day. Reduced sleep may also lead to fatigue during the day (duh) and less physical activity, which may be another reason why people who regularly don't get enough sleep tend to gain weight.
Gaspari lives by this rule. "In the weight room, I shorten my rest periods and use advanced techniques like supersets, compound sets, and dropsets to build muscle and burn fat. The key here is to keep training hard and heavy," he says. "Don't trick yourself into thinking that you have to use really light weights and high reps. If you put your mind to it, you can still train just as heavy at a fast pace."
Although you won't be able to completely transform your body or even lose more than a few pounds in a month, you can jump-start your weight-loss journey and be well on your way to achieving your goals. Just be mindful that while you can lose weight in a month, you can't specifically target your belly; there's no such thing as being able to spot-reduce fat (your body decides where the fat comes from - yay, genetics!). We tapped registered dietitian and ACSM-certified personal trainer Jim White, who owns Jim White Fitness and Nutrition Studios and helps clients reach their weight-loss goals, for insight on how to lose belly fat in 30 days.
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.
