When to eat

Having an early dinner and increasing the time of your fasting window can have positive effects on your body, such as better glycaemic control.

Some experts argue one meal a day is the best. Throughout history, we consumed one meal a day. But others disagree. Since one meal can increase the level of glucose in our blood when we're not eating, over a long period, it can be a risk factor for type 2 diabetes.

Instead, two to three meals a day is best, with a long fasting window overnight, and consuming most calories earlier in the day.
