LCHF and high cholesterol

It doesn't have to be high fat, just increased good fats. There is no need to go overboard with it. All you need is enough extra fat and/or protein to make up the lost energy from the lower carbs. The amount of increase is up to you. Some forumites are reporting lower cholesterol on this diet, but we are not all the same and it is just a case of suck it and see.

Increasing the fats to make up for lower carbs doesn't mean your blood cholesterol will go up. See how you go and hopefully a cholesterol test will show no increase and many report a decrease.

For most on the LCHF ,cholesterol values are reduced and the HDL [ good cholesterol ] is increased. In addition triglycerides are reduced, which is also good. As was said above the higher fats are need as a source of energy to replace the reduced carbohydrates. So with the LCHF you gain both ways ie improved lipid profile and much improved BG values.
