A new study from Science Daily:
Limiting access to food in mice increases levels of the hormone, ghrelin, which may also increase motivation to exercise, according to a study published in the Journal of Endocrinology.
The study suggests that a surge in levels of appetite-promoting
hormone, ghrelin, after a period of fasting prompted mice to initiate
voluntary exercise. These novel findings indicate that better diet
control, for example limiting food intake to mealtimes or fasting
intermittently, could help overweight people maintain a more effective
exercise routine, lose weight and avoid debilitating complications such
as diabetes and heart disease.
