Weight Loss: This Technique Boosts Exercise Motivation

The technique could help overweight people lose weight and keep it off.

Not eating much between meal times can help to increase exercise motivation, new research finds.

Only eating at mealtimes, along with intermittent fasting, both increase the levels of a hormone called ghrelin in the body.

Ghrelin, which increases appetite, boosts the motivation to exercise.

The extra exercise will help overweight people lose weight and keep it off.

It may be possible to use drugs that mimic the effect of ghrelin to increase exercise motivation, the researchers write.

Dr Yuji Tajiri, study co-author, said:

“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.”

The results come from a study of mice, which compared those given free access to food with those only fed twice a day.

The results showed that both groups ate the same amount of food.

However, the mice that only ate twice a day did more exercise.

Dr Tajiri said:

“These findings and previous reports are based on animal studies; so much more work is needed to confirm that this ghrelin response is also present in people.

If it can be established in clinical practice, it not only opens up new cost-effective diet and exercise strategies but may also indicate a new therapeutic application for ghrelin-mimicking drugs.”
