Intermittent fasting is currently a trend. One of the most popular methods among Americans is the Eat-Stop-Eat Diet, wherein you fast for 24 hours once or twice a week.
The question people always ask is: can this method actually help you lose weight?
Many people are afraid that fasting might cause their metabolism to crash, but according to Dr. Mike Russell, "Not eating for 24 or 16 hours isn’t going to crash your metabolism and render weight loss impossible."
Nevertheless, fasting success is only achieved when you eat healthy during and after fasting--otherwise you'd end up eating the calories you "fasted off" thereby making the whole process obsolete.
Intermittent fasting is effective for people who have a good grasp on healthy eating, as well as those who are experienced on a very low-carbohydrate diet (<10% of calories from carbs). If you struggle with this, Russell recommends that you focus on developing nutritional habits instead for long-term diet success.
