Today's three-minute lesson

Breakfast is a signal, not just a meal

Your brain is not the only part of your body that follows a daily rhythm.

Almost every organ and tissue has its own internal clock. These clocks help your body anticipate what is likely to happen next rather than waiting to react when it does.

Light is the strongest timing cue for the clock in your brain, but food timing also helps organise rhythms throughout the rest of the body.

Eating your first meal at roughly the same time each morning gives your body another consistent point around which to organise the day.

What you eat matters too.

A breakfast built around protein is generally more satisfying and can support steadier energy throughout the morning.

It does not need to be elaborate. Eggs, Greek yoghurt, or even a protein shake can all work. If you prefer cereal, toast or oats, add a source of protein rather than relying on them alone.

You do not need to eat the moment you wake up. Aim to have your first meal around 90–120 minutes after getting up, at roughly the same time each day.

As with every habit this week, consistency matters more than precision. Breakfast does not need to happen at exactly the same minute every morning.

The aim is to give your body a recognisable pattern: morning light, movement and then a protein-rich breakfast at a fairly consistent time.
