Sorry to admit that this is new to me. To clarify so I get it:
Kid #1: 6' 3", 160 lbs, very skinny, almost invisible from the side.
Kid #2: 5' 10", 190 lbs, has muscles but lots of babyfat too.
Kid #3: 5' 11", 165 lbs, very lean and ripped.
All 3 want to get to 200lbs. All 3 need to consume 200g of protein per day?
Right?
Edit to ask also: Do Kids #1 and #2 need to consume just 170g per day, as they need to get to 170lbs before they can get to 200 lbs?
