Intermittent fasting: Should you exercise on empty?

Story highlights

  • Intermittent fasting can require dieters to forego food for 14 hours or more
  • You may shed more fat when exercising while fasting, but you may lose more muscle, too
  • Eventually your body will adjust to your drastic calorie intake, burning fewer calories per day

(Life by DailyBurn)Food is fuel. So what would happen to your exercise regimen if you weren't eating your standard three meals (plus snacks) per day?

Intermittent fasting, which can involve anything from fasting for 14 hours at a time to forgoing food a couple days a week, is all about restricting food consumption during specified periods. You consume little to no calories during "fasting" periods, and eat pretty normally during "feasting" times.
The end result is impressive weight loss, according to many devotees of this trendy diet. Some intermittent fasting methods even claim that this on-and-off eating plan can help regulate blood sugar, prevent diabetes, lower the risk of heart disease and slow the aging process.
