Intermittent fasting is popular. However, you should not expect to lose weight unless you also restrict your caloric intake. But there are still many important health benefits to intermittent fasting.
Not eating anything for 16 or 18 hours every day. Or not eating anything for two days a week. These are typical examples of popular intermittent fasting protocols, often followed by people who want to lose weight. The idea is that the body begins to tap into its fat stores when it doesn’t receive food during the fasting period, resulting in weight loss over time.
“There are indeed many health benefits to intermittent fasting, but fasting itself does not lead to significant weight loss”, says Philip Ruppert, a postdoc at the Department of Biochemistry and Molecular Biology, where he studies the body’s energy metabolism and has a particular interest in ketogenesis; the state where the body burns fat instead of carbohydrates.
Together with Sander Kersten, a professor at Wageningen University and Research in the Netherlands, he has authored a review article summarizing and discussing existing research on metabolic processes such as ketogenesis and fatty acid oxidation that come into play during fasting. The article is published in Trends in Endocrinology and Metabolism and can be seen here.

In my experience the most important part of intermittent fasting is in rebuilding ones relationship to hunger. By letting yourself be hungry for extended periods of time you will eventually develop less intense hunger pangs and cravings.
This was the key for me… IF shrinks your stomach. Hard two day fasts do this even more drastically and noticeable.
I’ve lost 35-40 lbs in just under a year with streaks of two day fasts for two month stretches and 18/6 the rest of the time.
I do not recommend the two day fasts. You’ll see much better results counting cals and maintaining a 400 cal deficit over time but I had different goals.
When your intermittent fasting, it’s more difficult to eat 3000 calories, and more difficult to eat just for social reasons.
So while the summary is factually correct, it ignores the positive pressures on calorie reduction that intermittent fasting provides.
Yeah, this is my experience. I’ve been following IF for the past 6 months now and don’t count calories or limit what or how much I eat within my 8 hour window. I still lost weight because there’s only so much you can eat in 8 hours, so I’m probably eating less than I would if I wasn’t fasting.
Same for me. It stopped my late night snacking, which was apparently a bigger problem than I realized.
Between that and stopping drinking, I dropped 40lbs without really trying.
Damn that’s good work. Well done.
