Surprisingly, since I've started intermittent fasting I've increased muscle mass (up 10 pounds from 205 to 215), decreased body fat (down 3% from 14% to 11%), increased explosiveness (set a personal best with a clean and jerk of 253 pounds a few months back), and decreased the amount of time I've spent training (down from 7.5 hours per week to 2.5 hours per week).
Getting back to intermittent fasting, many studies have confirmed the health benefits of calorie restriction, and it seems clear that eating less is part of the equation if you want to live longer. Interestingly, research4 has shown that life-long calorie restriction in mice "significantly changes the overall structure of the gut microbiota" in ways that promote longevity. So one reason why calorie restriction may lengthen lifespan appears to be due to the positive effect it has on gut microbiota.
As you can see all of the sample intermittent fasting meals included in the fat loss diet have a convenient source of protein, fruit and some healthy fats. This food combination is what I have personally found to be the most effective for staying satisfied on low calorie meals. The fruit is highly nutritious, easily digestible and is effective at replenishing liver glycogen.

A diagnostic fast refers to prolonged fasting from 8–72 hours (depending on age) conducted under observation to facilitate the investigation of a health complication, usually hypoglycemia. Many people may also fast as part of a medical procedure or a check-up, such as preceding a colonoscopy or surgery. Fasting may also be part of a religious ritual.
