"IF is an excellent tool to use while trying to gain muscle and get stronger," said clinical/sports nutritionist and personal trainer Autumn Bates, CCN, CPT. "Multiple studies show that IF helps to boost growth hormone, which assists in forming muscle."
"What's also unique about IF is that it boosts fat burning while maintaining (and forming new) muscle," she continued. "I use IF with many of my athlete clients to boost performance levels while increasing muscle mass and losing fat mass."
IF helped me gain muscle faster than ever before, which sped up my metabolism and helped me burn more fat over the long run. I couldn't believe how quickly I was losing body fat and simultaneously gaining lean muscle. This was especially the case around my midsection. My belly fat started coming off pretty fast, and it was the best feeling, since that's been a trouble area for me for a long time.
