Intermittent Fasting Not Working? Here’s What Could Be Going Wrong, By an RD
Intermittent fasting is having a moment. Whether you prefer to eat keto or plant-based or are just trying to make up for some extra indulging over the holidays, everywhere you turn someone is extolling the virtues of this simple, flexible diet strategy, where you eat for a window of time (usually 8 hours) and then fast and let your body go without any food for a longer window (usually 14 to 16 hours). This allows your your body to metabolize the food you eat and then shift from burning that as its fuel to burning fat for fuel.
