A piece of toast with peanut butter and some kind of fruit
Special K protein and some soy or almond plus milk. Easy and quick.
One of my go tos is overnight oats made with homemade kefir, uncooked oatmeal, chia seeds, cinnamon, vanilla, and whatever fruit...very satisfying.
Some people have it sorted. Stay away from oats and any carbs really. You want a meat and nut breakfast. I have eggs and beans, high protein moderate fat and low carb. Don't believe the hype behind needing carbs for energy.
I'm a nutrition student, in the morning you should base your meal on 2 things : protein and fiber. So the best i recommend is a slice or two of a good bread (not a white one) with peanut butter. On the side, take the fruit of your choice (banana, apple, orange... whatever you like) :)
This is just Me but it gets me off to a great start:
1scrambled egg cheese + salsa
Half cup blueberries and black berries mixed with chopped nuts and fresh mint.
Drink a ton of water
Honestly every one Has different bodies and opinions. Go with what makes you feel good and is well rounded.
Trainers students and nutritionists are all going to tell you different variations so just make your own decision . Obviously not pizza!
