"Intermittent fasting doesn't guarantee weight loss. Some studies have shown it can be beneficial for weight loss/management but not if you're eating excessive amounts of food during your eating window," registered dietitian nutritionist and NASM-certified trainer Whitney English Tabaie, MS, RDN, CPT, told POPSUGAR.
If you're eating from the minute your window opens to the very last second that your window closes (just one more handful of popcorn!), and you're not tracking your calories, there's a good chance that you're overeating.
Intermittent fasting works because limiting your eating window is a means of calorie restriction and eating fewer calories than you burn helps with weight loss.
Tabaie added that fasting isn't for everyone. She explained that for some people, restricting eating hours "can lead to binge eating, which would be counterproductive to weight-loss attempts. This is why I recommend intermittent fasting for potential health benefits and not as a weight-loss strategy."
