Does basal metabolic rate predict weight gain?
body composition body-weight change clinical research energy expenditure free-living adults indirect calorimetry longitudinal follow-up
2018/12/14
Background: Some previous studies have indicated that a low basal metabolic rate (BMR) is an independent predictor of future weight gain, but low rates of follow-up and highly select populations may l...

2016/6/12
Geophysical monitoring of the ground above active supervolcanoes shows that it rises and falls as magma moves beneath the surface of the Earth. Silica-rich magmas -- like those in the Yellowstone regi...
Low energy intake plus low energy expenditure (low energy flux), not energy surfeit, predicts future body fat gain
energy balance energy flux physical activity doubly labeled water weight gain
2018/11/30
Background: There is a paucity of studies that have prospectively tested the energy surfeit theory of obesity with the use of objectively estimated energy intake and energy expenditure in humans. An a...
Higher compared with lower dietary protein during an energy deficit combined with intense exercise promotes greater lean mass gain and fat mass loss: a randomized trial
athlete dietary protein leucine skeletal muscle resistance exercise high-intensity interval training
2018/11/28
Background: A dietary protein intake higher than the Recommended Dietary Allowance during an energy deficit helps to preserve lean body mass (LBM), particularly when combined with exercise.
High protein intake in young children and increased weight gain and obesity risk
High protein intake young children increased weight gain
