body composition, some trainees are able to look high up or low down without risking their safety, but these guys are exceptions to the rule and should not be viewed as role models for the
average lifter.
Now I know that some of you are STILL worried about cardio burning muscle so lets look at a great study (1,2,3) where they monitored
body composition of athletes in the trans - europe run where they ran 2800 miles in 64 days — that's an
average 43 miles a day.
If I want to lose fat, I'm looking to consume roughly 1900 calories / day on
average, which is a ~ 20 % deficit of 2400 calories / day, that being what I'd want to consume if I wanted to maintain my weight and
body composition.

average, or calculate how many calories and where they should come from to meet your
body composition goal, and MORE!
The estimated
average daily calorie requirement is 2000 for women and 2500 for men, this is just an estimate and will depend on your age, weight, height,

body fat, up to the point where your
body composition rating is BETTER than

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.
