In a high quality seven day, randomized, crossover study conducted by Sunehag et al. (2002), twelve healthy, non-obese adolescents (six males, six females) were maintained at home on prepared, isocaloric diets containing 60 % carbohydrate, 25 % fat, and 15 % protein, with 10 % or 40 % of the carbohydrate (6 or 24 % of dietary energy) content provided by fructose (low fructose or high fructose diet, respectively)... The total amounts of fructose ingested in the low and high fructose diets were estimated to be 36 and 133 g / day in females and 40 and 136 g / day in males.

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.
