Sentences with phrase «expenditure following weight»

Not exact matches

where ALF = Activity Level Factor DCE = Daily Caloric Expenditure HC = Height in Centimetres HI = Height in Inches WKG = Weight in Kilograms WP = Weight in Pounds and «Activity Level Factor» has the following values «Sedentary»: Activity Level Factor = 1.2 «Lightly Active»: Activity Level Factor = 1.375 «Moderately Active»: Activity Level Factor = 1.55 «Very Active»: Activity Level Factor = 1.725 «Extremely Active»: Activity Level Factor = 1.9

This is further compounded by elevations in metabolic efficiency (whereby energy expenditure declines beyond that predicted from the change in metabolic mass) and appetite which accompany weight - loss, and may ultimately predispose to weight re - gain.82 Moreover, changes in neural activity within brain regions known to be involved in regulatory, emotional and cognitive control of food intake have also been observed following weight - loss.83

The greater the decrease in physical activity energy expenditure (PAEE) during the energy deficit, the greater the weight gain during the follow up.

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.
