One of the hottest concepts out right now in terms of nutrition is IF, aka Intermittent Fasting. This new idea is very controversial to say the least, as it goes against the grain of traditional eating as we know it in the fitness world. So to get started letâ€™s answer what is intermittent fasting? To break it down simple stupid, intermittent fasting is nothing more than fasting in a structured time format each day. This means you will be fasting â€“ not eating â€“ for a period ranging from 16-36 hours pending on which format you choose all having various benefits. Think of it like interval training when you are working out. Intermittent fasting is interval training when you are eating. Has anyone tried this method before??? i know a guy at the gym that is doing this and he says it is working great he is losing weight keeping size and strength. Any views on it??
