- Fasting for 16 hours
Fasting for 16 hours a day with an 8-hour window to eat is called the 16:8 method or the Leangains diet.
In the 16:8 diet, men fast for 16 hours and women for 14 hours each day. This type of intermittent fasting may be useful for people who have already tried the 12-hour fast without any benefit.
During this fasting period, people typically finish dinner at 8 p.m. and the next day skip breakfast and don’t eat until noon.
A study conducted on mice by Trusted Source found that limiting the food intake window to 8 hours protected the mice from obesity, inflammation, diabetes and liver disease, even when they ate the same total number of calories as mice that ate when they wanted to.
