Elevated LDL-cholesterol levels among lean mass hyper-responders on low-carbohydrate ketogenic diets deserve urgent clinical attention and further research
Wow, this might actually be me. When I was doing a protein-heavy, carb-light diet, my numbers matched up with these ranges exactly. High LDL, high HDL over 80, and low triglycerides. Granted that was a good 15 years ago, but still. Glad to have something specific to look for.
