NORTH DAKOTA (KXNET) — People can say goodbye to the days of counting calories to lose stubborn pounds, because intermittent fasting is resurfacing in the fitness world. Dr. John Jaquish, who is a scientist, inventor, and author, tackled myths that have been dominating the fitness industry. He also introduces a routine that helps shed unwanted weight and enhances muscle tone, all without having to battle hunger. "When the toned gym buffs look no different from the folks munching away at the pizza joint, you know there's a hiccup in the traditional gym formula," he said. "My exploration into the human body's workings unveiled a different, more promising trail to fitness." Intermittent Fasting, or time-restricted eating, is a no-brainer — you fast for a chunk of the day and eat during the rest. This method scores more points than the habit of nibbling on calories. Keep spooky season safe for pets Here are some of the benefits of Intermittent Fasting: Metabolism stays even unlike with calorie restriction where the body becomes a rebel, piling on pounds even while dieting. Kickstart autophagy — the body's natural process of getting rid of old, damaged cells and creating new, healthy ones. The immune system gets a heart boost to rejuvenate core cells and defend against illnesses. Cranks up the growth hormone production. Puts the brake on hunger. Here's what happens when you fast. At the 12-hour mark, your body flips the switch and starts to burn fat for fuel when it begins to run low on sugar. At the 18-hour mark, fat-burning kicks up another notch. Around the 48-hour mark, growth hormone levels start to shoot through the roof, about five times the normal amount. Two hours later, at 50 hours, insulin levels hit rock bottom. When 72 hours come around, your body rejuvenates a big chunk of your immune system, which beefs up your defense against germs and illnesses. "Research is cheering on fasting as a gem for your health," Dr. Jaquish concluded. "It's a tried-and-true method to hold onto muscle, shed fat, and even boost muscle growth post-fasting. And oh yes, there's a smart way to fast to snag all these benefits." Close Thanks for signing up! Watch for us in your inbox. Subscribe Now Today's Top Stories SIGN UP NOW
