Why LCHF works

note to self:

 At the fat cell, an enzyme called lipoprotein lipase (LPL) acts as the doorman, ushering fatty acids into the fat cells.  Inside the fat cell, another enzyme, hormone sensitive lipase (HSL), has the job of cleaving the first sulfide bond on the triglycerides and releasing fatty acids to be used as energy.  So LPL is working when you are storing fat and HSL is working when you are “burning” fat. Here’s the rub – both of these enzymes are sensitive to the presence of insulin.  When insulin  is present, LPL is on duty and you are storing fat.  When insulin is gone, HSL is on duty and you are using your stored fat as energy.

self add
Insulin is controlled, in an undamaged metabolism, by carbohydrate intake. Cut the carbohydrates cut insulin, cuts fat storage, turn on fat release. Now here is the odd thing, on LCHF the efficiency of the calories seem to decrease.
