There are a few nutritionists that have been using lipid profiles to determine what type of macro ratio to target and I used that info to put together my weight loss strategy for this season, since I had a recent lipid profile handy in my medical records
N=1 caveat applies, but my lipid profile recommended an equal macro ratio and its been working really well for me.
I used this book as a reference: Turn Up The Heat - Unlock The Fat-Burning Power of Your Metabolism | PDF | Dieting | Obesity
