There have been many times when I've eaten what is now called a keto diet. When I was a teenager they said it would kill me. I never did go for the high starch and sugar diet that was heavily promoted to replace fat in the 70s and 80s.
Most of the stuff I've seen on chocolate, is good quality dark chocolate without so much sugar. A lot of
milk chocolate just filled with sugar and oils , and they really skimp on the most expensive ingredient, which is cocoa.
My gluttony knows no bounds, when I've been working hard and it's cold outside. When I was a teenager and in my twenties, people told me that I would be extremely fat by the time I'm 30. I'm 55 and still haven't gotten to where they said I would. So I'm going to continue binging on greasy steak and gobbling dark chocolate whenever the opportunity arises.
