Great information, well explained.
Our youngest did Keto to kick-start his weight loss combined with regular visits to the gym, he's since bought himself a Spiderman suit because he now has the physique for it, LOL
It's challenging though, you have to get used to a reduced range of foods.
For me, the misinformation about food is an early example of "trust the science, but that isn't the science". The food pyramid and everything we were told about what foods were good and bad was a complete fabrication, just to push processed food, corn syrup etc ... Special interests, using the government to mandate and profit.
Traditional food, fat, butter, taste, is what is healthier.
