It does seem counterintuitive, but I also found that by increasing fat on keto, I had good energy all day, and lost weight while gaining muscle with resistance exercise. This is largely because we are replacing the energy source of carbs with the energy source of fat. One thing you mentioned that I feel is relevant in this regard is the type of fat you increased. A lot of it was dairy fat. Dairy fat has MCTs in it. MCTs become ketones when they hit the liver. MCT fats have been shown to increase fat loss. This is probably because they end up as ketones which act as signalling molecules to the mitochondria. i consume MCTs every day.
I have switched to goat yogurt, however, for two reasons:
- it has twice the MCTs as American dairy
- It doesn’t have the A1 casein issues of American dairy, which has always seemed to bother me. Here the dairy fat is not really the issue, but the digestion of a primary protein is, because in many people it ends up throwing off beta-casomorphin-7, which I believe is a problem - JFYI. I will let you research that if you wish.
