THE FAST TRACK

INTERMITTENT fasting — going without food for a number of days every week — is good for the cardiovascular system, so might also help slow down age-related cognitive decline.

Try overnight fasting. Simply give yourself a ten to 12-hour break between dinner and breakfast.

This has been shown to reduce body fat and improve sensitivity to insulin, in turn protecting against obesity and diabetes — both known risk factors for cognitive ageing and dementia.
