Like it or not, towards the end of your sleep, your body begins to edge into a catabolic (tissue teardown) state, as the fuel from your last meal runs low.
It starts to tap in to fat for energy and muscles for amino acids. Basically, you have gone in to a fasting state, because no nutrients have been eaten for 6-8 hours (or more if you’re having a lay in).
The only way you can break this state (which is disastrous for putting on muscle), is by eating.
Jump start your metabolism and get out of that catabolic state, by chowing down on protein, carbs and healthy fats, as soon as you can.
Give protein the priority. Protein provides muscle-building amino acids. Muscle building favourites are eggs – and lots of them. As long as you’re not frying them have as many as you like, boiled, in an omelette, poached, scrambled…
If you’re on the run to get out the door in time grab some low fat cottage cheese which tastes nice with sliced fruit.
Breakfast is really important because it’s one of the windows in the day that your body will suck up whatever you give it, and use it, rather than store it as fat.
(The other two windows are during and after a workout).
