Fast Weight Loss Diet - Why Am I Not Losing Weight?
Fast diets are hugely detrimental due to their very approach, namely, drastic restriction of certain foods for a period of time.
There is no doubt that this approach works for a time, and a person may in fact quickly lose a lot of weight in this manner - up to two pounds a day. Unfortunately, loss of water accounts for a substantial share of the weight lost this way, as does the loss of muscle tissue, since protein stored in the form of muscles is the only nutrient that may be converted into glucose. Glucose is necessary to support an entire host of bodily functions. Deriving nutrition from ketone bodies would be an exception, but it takes a long time to reach this stage - not to mention that terminating a ketonic state leads to accelerated accumulation of fat.
Coincidentally, muscle mass accounts for about a third of all weight being lost (leading to apparent muscular dystrophy, accompanied by fatigue, hair loss, skin changes and depression). Fat does account for the remaining 20%, but only for a time, until the body shifts to a more economical mode. Quite often, this takes three or four days. After that, the share of fat in the total weight being lost goes down at the exclusive expense of muscle mass.
All this torture continues until the person finally slips. Once it does happen, the body, exhausted and all the wiser for this sad experience, will start accumulating fat to avoid another energy crisis in the future.
It should be noted that in the absence of concurrent strength training the muscle mass will not return to its original, pre-diet level. As a result, the person will gain the weight lost back, but now more of it will be fat than before the diet.
