Disregarding lab animals' circadian rhythms can hamper reproducibility, validity, and reliability of research, researchers say.
A new study reveals people who experience larger dips in blood sugar hours after eating end up feeling hungrier and eat hundreds of more calories a day than those who experience lower blood sugar dips.
Drinking a cup of strong coffee an hour before exercise, especially in the afternoon, increases fat-burning.
Mouse study reveals maternal exercise during pregnancy reduced the transmission of metabolic disorders from obese parents, whether the disorder was apparent in the father or mother.
During vigorous exercise, the body produces large amounts of the hormone GDF15, but the quantity is not sufficient enough to affect behavior or appetite.
Exercise promotes the hypothalamus to release MOTS-c. Mitochondrial encoded MOTS-c interacts with the nuclear genome and regulates both cell metabolism and the stress response.
Better glucose uptake compensates for age-related motor deterioration and extends lifespan in fruitflies.
B. longum APC1472 reduces blood glucose levels and reduces weight gain in mouse models. The bacteria also keep ghrelin, a hormone associated with hunger, and the stress hormone cortisol in check.
Drinking water can suppress the vasopressin hormone receptor, mitigating obesity and metabolic syndrome in mice.
The hunger hormone ghrelin doesn't just influence where and when animals eat, it also appears to have an impact on memory. Disrupting signaling of ghrelin to the vagus nerve caused rats to forget they had just eaten, even though the animals remembered they had just had access to food. Findings suggest disrupted ghrelin signaling could negatively impact episodic memory.
