Intermittent fasting can absolutely help decrease your calorie intake, but if you're ravenous and aren't mindful about how much you're eating, you can easily eat a daily calorie surplus, making you gain weight. I definitely made that mistake in the first few months of IF.
Over the past three months, I made a point to listen to my body, practiced portion control, and stopped eating when I was satisfied but not stuffed. I didn't allow the clock to dictate my meals and snacks, and I ate when I felt hungry within my eating window. Drinking tons of water and eating whole foods made this much easier.
