While the Internet is full of dubious wellness trends, one thing is often cited as scientifically proven: temporary fasting, where participants limit their food to specific times of the day or specific days of the week. Some scientific evidence shows that intermittent fasting has some benefits for heart health and neurogenesis. A recent study by the Mount Sinai School of Medicine in Cell found that practicing intermittent fasting can reduce acute inflammation and help inflammatory chronic diseases. However, nutritionists and eating disorders specialists point out that intermittent fasting aspects can be dangerous as they can damage people's relationship to food.
According to experts, one of the most common problems with intermittent fasting is that it can unbalance your body from its natural feelings of hunger and satiety. "Eating only for a certain amount of time per day separates us from our body," says Alissa Rumsey, a New York based dietician and founder of Alissa Rumsey Nutrition and Wellness, to Bustle. "It causes people to go hungry, which means they starve as soon as they eat, and it can be difficult to stop eating." The body has its own internal clock, which is moderated by many external factors, including sunlight and sleep. This determines when we are starving.
Experts are worried about the impact of restrictive nutritional plans on our internal clocks ̵
1; and therefore on other aspects of our health. "Restricting your diet at certain times of the day will ignore your body's needs, leave you undernourished, and swing the pendulum in the other direction as soon as you have permission to eat," says nutritionist Emily Fonnesbeck, RD, to Bustle , "This type of dysregulated, random, and chaotic eating behavior adversely affects hormone balance, immunity, digestion, and sleep patterns, and while intermittent fasting seems healthy, it can lead to discomfort."
