If you're unfamiliar, intermittent fasting (IF) simply involves narrowing the window in which you eat during the day, which may boost immunity, among other benefits, and help you lose weight. "To lose weight, you need to create a calorie deficit, where you burn more calories than you take in. Limiting your eating window with IF makes that goal easier to achieve," Lauren told POPSUGAR. "The available research shows similar weight loss results over time among any type of diet, but it also shows some improvements in blood sugar and insulin levels for those who followed IF."
While she advises against IF methods that involve fasting for longer periods of time (at times, even whole days), limiting your window to, say, eight hours is usually realistic and safe.
Because there are so many ways to approach IF, and there are no set rules regarding which foods you can eat, it's really easy to customise it to match your goals and lifestyle. If you want to give IF a try, but aren't ready to go all in, Lauren recommends cutting yourself off within four hours of bedtime. Regardless, always talk with your doctor first if you are taking medications, have blood sugar issues, or have any history of disordered eating.
