Is a 14–16 hour fast necessary to gain benefits?

No, a 14 to 16 hour fast isn’t necessary to get benefits.

Here at Alloy, we generally see intermittent fasting as something that can help with weight and metabolic health for some people, but it needs to fit your life and not create stress. In our menopause nutrition content, Keri Glassman, MS, RD, often recommends a more “natural” intermittent fast of about 12 hours overnight for most people, since you can still get benefits like cutting out late night snacking, without forcing a longer 14 to 16 hour window that can feel disruptive.

Dr. Taylor Hahn makes a similar point for weight control, fasting can be helpful, but it’s not the only way to lose weight, and it should be something you can sustain.
