The Real Difference Between Alternate Day Fasting And Intermittent Fasting
- June 02, 2021
As nutrition professor and author of The Every-Other-Day Diet Krista Varady, PhD, advised The Healthy, you could lose more weight doing alternate day fasting but it might also be more difficult to stick to it, particularly considering the most popular 5:2 method involves fasting for two days a week and eating for five (hardcore fasters may choose to do 4:3 instead). Alternate day fasting aims to make your body burn fat instead of glucose, which should happen any time between eight and 72 hours, and typically encourages ketosis.
As Varady explained, “Alternate day fasting produces faster weight loss, about 10 to 15 pounds in three months, compared with time-restricted feeding. But it’s harder to follow because you have to count calories every other day.” Healthline reports a yearlong study of those taking an every-other-day approach, with food intake restricted to 500 calories on fasting days, ultimately wasn’t more effective than overall calorie restriction every day.
