Or go back 50 plus years and do the 36 eggs a day diet that Don Howorth did.
1 quart of milk
1 quart of cream
36 eggs
My shakes consist(ed) of:
milk
cream
1 egg
peanut butter
protein powder
MCT oil (squirt)
Around 1,000cals, 50g protein, 80g fat, 30g carbs, 22g sugar and delicious too.
Oh and I'd have a bit of oats with every sip.
