Limiting mealtimes may increase your motivation for exercise
A study published in the Journal of Endocrinology suggests that a surge in levels of appetite-promoting hormone, ghrelin, after a period of fasting prompted mice to initiate voluntary exercise.
Dr Tajiri comments, “Our findings suggest that hunger, which promotes ghrelin production, may also be involved in increasing motivation for voluntary exercise, when feeding is limited. Therefore, maintaining a healthy eating routine, with regular mealtimes or fasting, could also encourage motivation for exercise in overweight people.”
(Note that these findings are based on animal studies and more work is needed to confirm that this ghrelin response is also present in people.)
