If you want to lose weight, make better food choices, and feel empowered in the bargain, why not give 12-hour intermittent fasting a shot?! Don't worry — this is no fad diet. It's actually pretty simple and straightforward: Each day, you eat over a 12-hour period and fast for the remaining 12. If you're thinking, But won't I be super hungry if I don't eat for 12 hours??? no worries.
