I get about 50% of my protein from shakes - I also have fried eggs with pork in the morning and evening, and beef at lunch. Each protein shake is 45 grams whey - so 37 grams protein.
I'm passed the fat adaptation phase, and I'm now eating about 16 times bodyweight = 3200 caloreis. Keeping the fat % high. So far so good. lost 4kgs, dropped BF% down to 15%, and my muscle mass is marginally higher. I would ideally add in another portion of meat and drop one or two protein shakes, but it's too difficult for a number of reasons. My whey is mid morning, before gym, after gym and before bed. I was considering dropping the amount of whey. But including the whey my protein intake is 257 grams (I dont really want to go lower). Total macros: protein 33% (257 grams), fat 62% (219 grams), carbs 23.6 grams
