During ketosis, there is a decrease in the production and use of glucose and as a consequence in the breakdown of
proteins (found in muscles) are used as energy,» says the nutritionist of celebrities such as Jessica Alba: Kelly Leveque about this diet.
Thanks for the info, I found 2 weeks ago, that I have a hard time of burning fats... versus carbs
during training or maybe something else was going on (there was has been a change in my workouts from morning to evening too)... but I started eating 75g or so of carbs at night (with same training intensity,, mostly aerobic with 2 days of «speed») the following week my energy levels were back to normal... not sure I do so well in ketogenic state or perhaps I wasn't as balanced as I should have been (carb,
protein, fat) or my body just isn't acclimitized to those things yet (
ketosis)... working on it though...
Adhering to these traditional concepts the US Department of Agriculture has concluded that diets, which reduce calories, will result in effective weight loss independent of the macronutrient composition, which is considered less important, even irrelevant.14 In contrast with these views, the majority of ad - libitum studies demonstrate that subjects who follow a low - carbohydrate diet lose more weight
during the first 3 — 6 months compared with those who follow balanced diets.15, 16, 17 One hypothesis is that the use of energy from
proteins in VLCKD is an «expensive» process for the body and so can lead to a «waste of calories», and therefore increased weight loss compared with other «less - expensive» diets.13, 18, 19 The average human body requires 60 — 65 g of glucose per day, and
during the first phase of a diet very low in carbohydrates this is partially (16 %) obtained from glycerol, with the major part derived via gluconeogenesis from
proteins of either dietary or tissue origin.12 The energy cost of gluconeogenesis has been confirmed in several studies7 and it has been calculated at ∼ 400 — 600 Kcal / day (due to both endogenous and food source
proteins.18 Despite this, there is no direct experimental evidence to support this intriguing hypothesis; on the contrary, a recent study reported that there were no changes in resting energy expenditure after a VLCKD.20 A simpler, perhaps more likely, explanation for improved weight loss is a possible appetite - suppressant action of
ketosis.
