The reality of weight loss is that it generally comes down to “calories in versus calories out”. In other words, we need to burn more calories than we consume in a given week if we wish to see the scale drop. While most people realize that, many of us do not want to spend precious time counting every calorie or restricting the types of food we eat.
One tool used for weight loss (as well as other health benefits) that has gained popularity recently is the method of intermittent fasting. Intermittent fasting (IF) is a term used to describe a timed method of eating that involves periods of eating along with periods of fasting (not eating). There are several methods used for IF . In this article, I will describe some of the most common methods and will explain how to do intermittent fasting to lose weight.
While the primary reason for weight loss is the overall net reduction of calories in a week when combining eating with fasting periods, IF also uses our natural circadian rhythm to optimize fat burning and metabolic rate through fasting. Some studies show that IF leads to greater fat loss with a reduction in the amount of muscle lost in subjects who use IF for weight loss compared to those who do diets involving continuous calorie reduction.
