I won't repeat what's been said, but I have blood tests every year and my 'total' cholesterol has always been slightly above average. However the LDL (bad cholesterol) and HDL 'good cholesterol' ratios improved significantly after following a low carb diet. It's rather weird that the time I lost the most weight was when I consumed eggs, cheese, meat, fish, butter etc.
There's also the fact that it's never been healthy to mix foodstuffs. We didn't evolve like that. For millions of years our digestive system coped with meat for a while, then berries, then roots, then other plants, then....corn etc. The meat, potatoes, veg diet means your enzymatic juices are all mixed and a lot of food goes undigested. So your body uses all the sugars and carbs (c.f. petrol) which are basically long-chain sugars, then the protein and fats.
You have enough energy from the carbs? What happens to the fats? Into the bloodstream, stored in adipose tissue. Partly digested meat? Smelly farts!
