Moderate energy restriction increases bone resorption in obese postmenopausal women
energy restriction weight loss obesity
2016/6/12
Weight reduction reduces bone mineral density
(BMD) and increases the risk of osteoporosis.
Comparison of the effect of dietary fat restriction with that of energy restriction on human lipid metabolism
Energy restriction fat cholesterol
2016/6/12
Dietary fat and energy have been implicated as
factors controlling circulating total and LDL-cholesterol concentrations.
Whether these factors work independently or synergistically
in regulating hu...
Effect of prolonged moderate and severe energy restriction and refeeding on plasma leptin concentrations in obese women
OB gene obesity leptin
2016/6/1
Plasma leptin in humans is subject to both longand
short-term regulation; it correlates with indexes of body fat
that can only change slowly. However, short-term fasting causes
large and rapid decr...
Acute effects of moderate dietary protein restriction in patients with idiopathic hypercalciuria and calcium nephrolithiasis
Idiopathic hypercalciuria dietary proteins nephrolithiasis
2016/5/30
High dietary protein intake is a potential risk factor
for nephrolithiasis because of its capacity to increase urinary calcium
and to facilitate lithogenesis through many other mechanisms.
Calorie restriction accelerates the catabolism of lean body mass during 2 wk of bed rest
Healthy volunteers muscle inactivity protein metabolism hypocaloric diet bed rest leucine kinetics
2008/12/22
Background: Muscle inactivity and low energy intake commonly occur in persons with acute or chronic disease, in astronauts during space flight, and during aging.Objective: We used a crossover design...
A controlled trial of reduced meal frequency without caloric restriction in healthy, normal-weight, middle-aged adults
Caloric restriction meal frequency intermittent fasting cholesterol metabolism blood pressure
2008/12/12
Background:Although consumption of 3 meals/d is the most common pattern of eating in industrialized countries, a scientific rationale for this meal frequency with respect to optimal health is lacking....
Validation study of energy expenditure and intake during calorie restriction using doubly labeled water and changes in body composition1,2,3
Doubly labeled water method DLW energy intake body composition metabolic chamber
2008/12/9
Background: Clinical trials involving calorie restriction (CR) require an assessment of adherence to a prescribed CR with the use of an objective measure of energy intake (EI).Objective: The objective...
Calorie restriction and aging: review of the literature and implications for studies in humans
Dietary restriction energy expenditure aging
2017/1/4
Calorie restriction (CR) extends life span and retards age-related chronic diseases in a variety of species, including rats, mice, fish, flies, worms, and yeast. The mechanism or mechanisms through wh...
Energy metabolism after 2 y of energy restriction: the Biosphere 2 experiment
Metabolic rate physical activity energy restriction aging
2016/6/8
Background: An adaptive decrease in energy expenditure (EE) in
response to 6 mo of severely restricted energy intake was shown
in a classic semistarvation study—the Minnesota experiment.
Objective:...
Dietary restriction and walking reduce fat deposition in the midthigh in obese older women
Obesity computed tomography fat-free mass exercise VO2max maximal oxygen consumption
2016/6/8
Background: It is suggested that fat deposition within midthigh
muscle, represented by low-density lean tissue, increases with
deconditioning and obesity and is associated with risk factors for
car...
Dietary composition and physiologic adaptations to energy restriction
Obesity glycemic index energy-restricted diet energy expenditure blood glucose insulin leptin nitrogen balance feeding behavior young men
2016/6/3
The concept of a body weight set point, determined
predominantly by genetic mechanisms, has been proposed
to explain the poor long-term results of conventional energyrestricted
diets in the treatme...
Postprandial lipemia: effects of exercise and restriction of energy intake compared
Exercise triacylglycerol women energy deficit lipemia fat ingestion lipid metabolism insulin fatty acids
2016/6/3
Background: The mitigating effect of exercise on postprandial
lipemia may be attributable to the energy deficit incurred.
Objective: We aimed to compare the effects of prior exercise
and an equival...
Dietary n23 fatty acid restriction during gestation in rats: neuronal cell body and growth-cone fatty acids
Brain growth cones docosahexaenoic acid 22:6–3 arachidonic acid 20:4–6 rats n–3 fatty acids
2016/6/3
Growth cones are membrane-rich structures
found at the distal end of growing axons and are the predecessors
of the synaptic membranes of nerve endings. This study examined
whether n23 fatty acid re...
