Diet Myth or Truth: Fasting Is Effective for Weight Loss

The most prevalent of these contaminants was creatinine , a breakdown product of creatine also produced by the body. Heavy metals contamination was not found to be a concern, with only minor levels of mercury being detectable. Two studies reviewed in found no impurities. In , Harvard University researchers Otto Folin and Willey Glover Denis found evidence that ingesting creatine can dramatically boost the creatine content of the muscle. The substance creatine is naturally formed in vertebrates.

While creatine's influence on physical performance has been well documented since the early twentieth century, it came into public view following the Olympics in Barcelona. An August 7, article in The Times reported that Linford Christie , the gold medal winner at meters, had used creatine before the Olympics. An article in Bodybuilding Monthly named Sally Gunnell , who was the gold medalist in the meter hurdles, as another creatine user.

In addition, The Times also noted that meter hurdler Colin Jackson began taking creatine before the Olympics. At the time, low-potency creatine supplements were available in Britain, but creatine supplements designed for strength enhancement were not commercially available until when a company called Experimental and Applied Sciences EAS introduced the compound to the sports nutrition market under the name Phosphagen. It is ineffective as a treatment for amyotrophic lateral sclerosis.

A meta-analysis found that creatine treatment increased muscle strength in muscular dystrophies, and potentially improved functional performance. Creatine's impact on mitochondrial function has led to research on its efficacy and safety for slowing Parkinson's disease. As of , the evidence did not provide a reliable foundation for treatment decisions, due to risk of bias, small sample sizes, and the short duration of trials.

Religious and cultural fasts are typically undertaken as an act of devotion, last from hours, and are not intended to promote weight loss. Fasts lasting a day or two are unlikely to be dangerous for most healthy adults. But high-risk people, the elderly, anyone with a chronic disease, pregnant women, and children are advised against any type of fasting.

The real danger lies in staying on the fast for prolonged periods, anywhere from three days to a month. When you dramatically reduce your calorie intake, you will lose weight. But it can also cause all kinds of health problems, including muscle loss.

Further, when you start fasting, your body goes into conservation mode, burning calories more slowly. Keep in mind that the initial weight lost on a fast is primarily fluid or "water weight," not fat. And when you go back to eating, any lost weight usually gets a return ticket back.

Not only do most people regain weight lost on a fast, they tend to add a few extra pounds because a slower metabolism makes it easier to gain weight. Worse, the weight that is regained is likely to be all fat -- lost muscle has to be added back at the gym. Side effects of fasting include dizziness , headaches , low blood sugar , muscle aches, weakness , and fatigue. Prolonged fasting can lead to anemia , a weakened immune system, liver and kidney problems, and irregular heartbeat.

Fasting can also result in vitamin and mineral deficiencies, muscle breakdown, and diarrhea. When you drink laxative concoctions during a fast, there is an increased risk of fluid imbalance and dehydration.
