Not exact matches

We studied the consequences of a 15 % increase in energy from dietary protein in 19 subjects under weight - stable conditions (isocaloric diets) during the first 4 wk of the protocol and during active weight loss (ad libitum diet) in the final 12 wk of the protocol.

In conclusion, a 15 % increase in energy from dietary protein at constant carbohydrate intake produces a sustained decrease in ad libitum caloric intake that may be mediated by increased CNS leptin sensitivity and results in clinically significant weight loss.

Conclusions: An increase in dietary protein from 15 % to 30 % of energy at a constant carbohydrate intake produces a sustained decrease in ad libitum caloric intake that may be mediated by increased central nervous system leptin sensitivity and results in significant weight loss.

LCKD was instructed to consume an ad libitum diet and restrict carbohydrate intake to less than 50 grams per day (< 10 % of total energy) and CON maintained usual dietary intake.

After visit CRC2, the dietary macronutrient distribution remained fixed at 20 % fat, 50 % carbohydrate, and 30 % protein; however, subjects were instructed to eat only as much of the diet as they wished (ad libitum phase).

It is concluded that application of the glycemic index in isolation to judge the role of white vegetables in the diet and, specifically in the case of potato as consumed in ad libitum meals, has led to premature and possibly counterproductive dietary guidance.»

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.
