Arnold Schwarzenegger Shares How Fiber Boosts Gut Bacteria for Weight Loss

We can all rely on bodybuilding legend Arnold Schwarzenegger to share his invaluable tips, guidance, and experience. His latest nutrition insight, however, surpasses supplements and proteins. The seven-time Olympia champion shone the spotlight on fiber and its benefits for your gut and weight loss.

According to his newsletter, Arnold’s Pump Club, scientists have discovered a wonder that can make your gut bacteria actually burn some calories for you: fiber. Including high-fiber foods in your diet causes your gut microbes to grow faster, consuming the energy released by your meals before it sticks to your body. Plus, fiber helps with better bowel movements, thus “eliminating” calories better.

In simple terms, more fiber equals more good bacteria. Good bacteria do the brilliant job of feasting on the calories that you feed your body and leaving fewer calories for your body to store.

He demonstrates his bicep curls form showcasing his huge, bulging biceps. It was held the day after the 2nd Ms Olympia contest,in August,1981. Arnold has gone on to a career as a successful action film star and served as a Republican governor of California.

As per Arnold’s Pump Club, some of the best high-fiber foods you can include in your diet are:

Oats
Whole grains
Legumes
Vegetables
Fruit

According to Schwarzenegger’s newsletter, one of the best sources of fiber is psyllium.

Paired with regular exercise, your fiber-rich diet can help you manage your weight better. Plus, the fiber in your diet helps you feel full for longer while promoting a healthy gut microbiome.
