Variations in energy intake: it is more complicated than we think
Variation energy intake complicate
2018/11/20
Weight gain and the resulting obesity is fundamentally the consequence of chronic energy imbalance, with energy intake exceeding energy expenditure, which then leads to excessive energy (fat) storage.
Investigating predictors of eating: is resting metabolic rate really the strongest proxy of energy intake?
appetite eating behavior traits energy intake error variance resting metabolic rate
2018/11/20
Background: Evidence suggests that fat-free mass and resting metabolic rate (RMR), but not fat mass, are strong predictors of energy intake (EI). However, body composition and RMR do not explain the e...
A review of the characteristics of dietary fibers relevant to appetite and energy intake outcomes in human intervention trials
weight management appetite regulation viscosity gelling fermentability molecular weight dietary fiber properties
2018/11/19
Background: Many intervention studies have tested the effect of dietary fibers (DFs) on appetite-related outcomes, with inconsistent results. However, DFs comprise a wide range of compounds with diver...

Protein supplements after weight loss do not improve weight maintenance compared with recommended dietary protein intake despite beneficial effects on appetite sensation and energy expenditure: a randomized, controlled, double-blinded trial
BMI calcium fat mass lean body mass protein soy weight maintenance weight loss whey
2018/11/16
Background: High-protein diets increase weight loss (WL) during energy restriction; therefore, it has been suggested that additional protein intake may improve weight maintenance (WM) after WL.
