Fasting to Lose Weight (I)
How Good is Fasting to Lose Weight? Not eating seems like the ideal formula to lose weight but… Is it really so?
Although the public is constantly bombarded with pseudo diets that promise extraordinary results, few of these are nutritionally healthy or are based on scientific principles.
As noted above, caloric restriction have rational scientific basis, but it is often difficult to implement because people do not follow it, other special dietary strategies developed through the years to help fight the density, including total fasting, fasting with supplements and very low calorie diets.
The total fast became popular as a treatment soon 30 years ago, although the observations of the effects of prolonged fasting literature have appeared since the nineteenth century.
Weight loss in the first ten days is as fast as 1.1 kg / day and stabilized at 0.36-0.47 kg / day at the end of the first month.
Although these results are quite spectacular, it soon becomes evident that fasting has complications, the main thing is the negative nitrogen balance resulting in loss of lean body tissue.
During the first month, the average loss of nitrogen is 4.0 g / day and stabilized at 2.4 g / day, ie a loss of 3.5 kilograms per month of lean body mass, negative nitrogen balance does not generally affect plasma proteins, even during prolonged fasting, and total plasma protein, albumin, globulin and transferrin, generally remain constant.
Weight loss can be attributed to loss of lean body mass, body fat or water, during the initial two weeks of fasting total water loss is high and only 30-50% of the weight loss is fat, and 6-10% is protein. After a month, 70% of lost weight is fat, and 5% protein.
Clinical problems associated with prolonged fasting include electrolyte abnormalities, postural hypotension, hypokalemia frank, gouty arthritis, anemia and marked loss of lean body mass.
