Reduced carb (carbohydrate), high protein diet programs are the latest dieting craze. However, fit after 50 amazon (Source Webpage
) before you go on the band wagon,
you will want to give some thought to a few things:
1. Low carb (ketogenic) diet plans deplete the healthy and balanced glycogen
(the storage kind of glucose) shops in your liver as well as muscles. When you deplete glycogen stores, you'll find that you dehydrate,
frequently causing the scale to drop considerably in the very first week or two of the diet. This is usually interpreted as weight loss when
it's actually mostly from dehydration and muscle loss. By the
way, this's one of the reasons that low carbohydrate diets are extremely
popular in the moment - there is a rapid initial, but deceptive fall in scale weight.
Glycogenesis (formation of glycogen) takes place in the liver and
muscles when adequate levels of carbohydrates are consumed - hardly any of this occurs on a low carbohydrate diet.
Glycogenolysis (breakdown of glycogen) occurs when glycogen is categorized to create glucose for use as fuel.
2. Depletion of muscle mass glycogen causes you to fatigue easily,
and makes exercise or movement uneasy. Research
suggests that muscle fatigue increases in just about direct proportion to the rate of depletion of muscle glycogen. Bottom
line is you do not feel energetic and you exercise and move
less (often without realizing it) and that is not good for caloric expenditure and basal metabolic rate (metabolism).
3. Depletion of muscle mass glycogen leads to muscle atrophy (loss
of muscle). This happens as muscle glycogen (broken
right down to glucose) is the gas of preference for the muscle during movement. There is always a fuel mix, but without muscle
glycogen, the muscle fibers that contract, while resting to
maintain muscle tone, contract less when glycogen is not immediately available in the muscle. Depletion of muscle
glycogen likewise causes you to work out and move below
normal which leads to the inability and muscle loss
to maintain sufficient muscle tone.
Furthermore, in the absence of sufficient carbs for fuel, the human body initially uses protein (muscle) and fat. the initial
phase of muscle depletion is fast, caused by the use of
readily accessed muscle protein for direct metabolism or perhaps for conversion to sugar (gluconeogenesis) for fuel. Consuming
excessive protein does not prevent this because there's a caloric deficit.
When insulin levels are chronically too low as they may
be in very low carbohydrate diets, catabolism (breakdown) of muscle protein increases, as well as protein synthesis stops.
