Intermittent fasting is a diet that alternates between fasting and eating regularly. According to research, intermittent fasting can help you control your weight and possibly prevent or reverse some diseases. But how do you go about it? Is it also secure?
What exactly is intermittent fasting?
Many diets concentrate on what to eat, but intermittent fasting focuses on when to eat.
You only eat at certain times during intermittent fasting. Fasting for a set number of hours per day or eating only one meal a few days per week can help your body burn fat. Scientific research also indicates certain health advantages.
Mark Mattson, a neurologist at Johns Hopkins, has been researching intermittent fasting for 25 years. He claims that our bodies have evolved to survive without food for many hours, days, or even weeks. Before humans learned to farm, they were hunters and gatherers who evolved to live — and flourish — for extended periods without eating. They had to: hunting wildlife and gathering nuts and berries required a lot of time and energy.
It was easy to maintain a healthy weight even 50 years ago. Christie Williams, M.S., R.D.N., a nutritionist at Johns Hopkins, explains: “There were no laptops, and TV shows were switched off at 11 p.m.; people stopped eating because they went to bed.” As a result, the portions were significantly smaller. In addition, more people worked and played outside, and they received more exercise in general.”
Nowadays, television, the internet, and other forms of entertainment are available 24 hours a day, seven days a week. We stay up later to watch our favorite shows, play games and talk online. We’ve been sitting and munching all day — and most of the night.”
Obesity, type 2 diabetes, heart disease, and other disorders can be exacerbated by more calories and decreased movement. According to scientific evidence, intermittent fasting may help reverse these changes.
