I continued to do morning CrossFit classes or runs, and I felt great since I was fueled from dinner the night before. I was used to not eating before my workouts, so nothing felt different here. I still had tons of energy and endurance. The only times I felt crappy were if I didn't eat enough protein and healthy fats the night before, but that had nothing to do with ADF.
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:
This South American tea comes from the yerba mate plant. Its leaves and twigs are dried, usually over a fire, and steeped in hot water to make an herbal tea. This caffeine-containing tea, often called mate, may help promote weight loss. Some consider it an ideal substitute for coffee, minus the bitterness. The Mayo Clinic advises, however, to enjoy this tea in moderation. Some studies have found that people who drink large amounts of mate over prolonged periods may be at increased risk for certain types of cancer such as cancer of the mouth, lungs and esophagus (smoking in combination with drinking mate increases the cancer risk).
Here we go! This one is a special elixir that cures the mind and body alike. The blueberries naturally expel unwanted toxins in droves, and they release ample B vitamins into the system, which promotes energetic exercise alongside active engagement. The lavender is also particularly soothing for the brain. In terms of detox water recipes, it is hard to find another brew that delivers such stamina and clarity. When selecting lavender leaves, it is wise to select mature plants with robust petals. The opposite is true for berries. With smaller varieties, more nutrients can be jam-packed into the detox blend.

Then began a long period of struggle. My weight bounced up alarmingly in September 2011. It was alarming in part because I was continuing with the same exercise and careful eating that had been working so well. One thing I think I have learned about weight loss is that the same regimen that works for losing weight when you’re heavy won’t work as well (or perhaps at all) when you’re considerably lighter. That seems to be in part just because you naturally need fewer calories just to maintain your weight when you weigh less. But that would only explain why my weight didn’t continue to go down; it couldn’t explain how, keeping the same regimen going, my weight would suddenly bounce back up so alarmingly. I suppose that could just be chalked up to my seasonal pattern of gaining weight in the Fall/Winter, but to me, because the bounce was so unusually sharp, this also seems to be going on: Sometimes, I think, when you lose weight, your (or at least my) body freaks out, thinking that it’s starving, and starts to “try,” as it were, to gain weight back, with some of its efforts not going to try to make you eat more (which efforts one can resist), but to slow down your metabolism. Or something. I didn’t and don’t really understand what was happening there, but what had been working was for some reason clearly no longer working. [So, there appears to be some research suggesting that metabolic changes are caused by weight loss that make it hard to keep the weight off. Some of this research is reported on in this New York Times piece by Tara Parker-Pope. See esp. the 6 paragraphs that begin with the sentence “Leibel and his colleague Michael Rosenbaum have pioneered much of what we know about the body’s response to weight loss.” I didn’t see there any suggestion of the kind of almost violent “freak-out” I’m conveniently positing here, though.]
So don’t do that. The Zero Belly Cleanse, from my book Zero Belly Diet, provides fast weight loss while avoiding the yo-yo pitfall. First, it reduces your calorie intake slightly, without radically altering the way you eat. There’s no sudden, dramatic food restriction, just a smart 7-day dining plan. Second, it incorporates short bouts of mild exercise to up your metabolic burn, without forcing you into intense, hard-to-stick-to workouts. And third, it keeps your body fueled with clean, powerful, high-nutrient foods that will boost your health while targeting unhealthy belly fat.
Side effects of fasting may include headaches, weakness, muscle aches, nausea, lightheadedness, irritability, racing heart, exacerbation of joint symptoms, mild abdominal discomfort, and hunger. However, everyone reacts differently to detoxing. While one person may feel energized and revitalized, another may feel sluggish. Generally it is reported that hunger disappear after the first day.
