Secondly, another concern that people have about fasting is the hunger that one might experience. Interestingly, when comparing intermittent fasting versus calorie restriction, is has been noted that the hunger response is more pronounced when on a calorically restricted diet than in fasting (5). In a 10-week study done on alternate day fasting for weight loss, it was found that after 2 weeks, the hunger response decreased significantly and continued to stay low (2).
I ended up following a very rigorous intermittent fasting program for a little over two months (April 6 through June 10), in which I not only fasted every other day, but, aside from that first non-fasting day, tried to be careful about my eating on non-fasting days in the way I had become used to being (and that had resulted in weight loss for the first few months of 2013). And I also kept up my exercise, doing a solid hour of aerobic exercise (usually on an elliptical machine, or, about once per week, running), working very hard for that hour, about 6 times per week. The results are shown in this chart:
Jeni S., a 31-year-old mom of two and group fitness instructor, first discovered cleanse diets after talking with a fellow fitness instructors. "I was complaining to her about my post-holiday bloat and she recommended I try a cleanse to 'flush' it all out and sort of reset everything." On her friend's recommendation, Jeni started with the Shakeology Jumpstart Cleanse—"a nutrient rich, calorie restrictive cleanse designed to help rid your body of undigested food and other toxins." She adds, "The goal is to get as many nutrients with as few calories as possible."
