Breakdown of the breakfast:
-Egg whites for faster protein digestibility
-Egg yolk for saturated fats (you NEED saturated fat and cholesterol for hormone regulation) and micronutrients
But wait, why no carbs!?
After sleeping, your body is in a carb depleted state. Your body has been using glycogen (carb stores) all night to keep your body functioning. Wouldn't it be smart to have carbs in the morning and replenish your glycogen stores? Yes and no.
You could have carbs and refill your glycogen stores to fill back up your muscles BUT this will turn off the fat-burning cascade that could go on without it. If you don't have carbs, your body will be forced to use up the rest of your glycogen stores and turn to fat stores instead for fuel (which is what we want!)
Having a protein and fats breakfast will also keep your body in a hormonal environment that encourages fat-burning. Your blood sugar is low along with your insulin levels upon rising which facilitates more fat-utilization for energy. Without carbs, your blood sugar and insulin shouldn't spike which blunts this process.
Also, without that blood sugar spike, your energy levels should stay maintained throughout the day. You won't get that jolt you get from having a high sugar meal BUT you also won't feel that crash that's also associated with it.
Honestly, I have been having a protein and fats breakfast for awhile now and I feel amazing. My energy is consistent throughout the day and I don't have that mid-morning or early afternoon crash.
I definitely recommend giving this a try for 7 days and let me know what you think!
