How 5:2 intermittent fasting differs from time restricted eating | Dr. Mark Mattson

Intermittent fasting depletes the liver’s carbohydrate stores causing the body to switch to fats and ketones for energy. Time-restricted eating that includes a fasting period between 16 to 18 hours per day is sufficient for this metabolic switching. 5:2 intermittent fasting is an eating pattern in which an individual consumes one moderate sized meal (about 600 calories) per day for two days per week while eating normally for the other five days. In one clinical study, participants experienced improved asthma symptoms when alternating between days of normal food intake and days consuming only 400 calories, a type of every-other-day intermittent fasting. In another study, women who were at high risk for breast cancer lost more belly fat and had increased insulin sensitivity practicing 5:2 intermittent fasting compared to women consuming a normal eating pattern with 25 percent reduced calories. In this clip, Dr. Mark Mattson discusses the differences between styles of intermittent fasting and time-restricted eating.
