Break A Sweat. Before You Break Your Fast.

There’s a good reason now, for you to hold off on your breakfast until after your workout.

According to a recent study published in the Journal of Clinical Endocrinology and Metabolism, ‘when’ you exercise could be as important as the exercise itself.

The study aimed to understand the long-term and short-term effects of eating after exercise versus eating before it, on the body’s fat-burning capacity and insulin response.

The results suggested that exercising before you have breakfast burns twice as much fat as compared to exercising after breakfast. What’s more, a change in the timing of when you eat in relation to when you exercise, brings about profound positive changes to your overall health.

Let’s understand why this happens.

Why Exercising Before Breakfast Is Good

When you exercise before breakfast,

  1. The body burns more fat. That’s because when we fast overnight, the insulin levels in the body are lower during exercise, and this allows the body to use up more fat.
  2. The body is able control blood sugar levels better. This means that exercising in the overnight-fasting state can increase the health benefits of exercise, with no change in the intensity, duration or perceived effort in the exercise.

But it’s important to keep in mind that while this does dramatically improve overall health, it does not have any effect on weight loss.
