Very helpful! I learned a lot on how FATS are so essential and the properties of coconut oil . The carb load of up to 300 grams is startling to me for all the “gurus’ I have read up until now (Ken Berry, Dave Asprey, Thomas Delauer,). But the science does not lie. The Keto bandwagon is just that…it seems to be a kind of nutritional snobbery with IF added to the mix. I have done IF….effortlessly…I found it a useful catalyst for my big weight loss and restricted window eating still makes some sense to me…but the useful role of carbs…I was told these were unnecessary. I heard the quote “there are essential amino acids (protein); essential fatty acids…but no essential carbohydrate” so I just accepted carbs were a drug to me tightly controlled if not eliminated. I sank to 50 grams or so for periods but no further. However, adding honey, fruit recently…I feel great!

When listening to number seven pod you and Mike talked about how it affects your body is it 20 something-year-old healthy man. But don’t you think that the higher carbs would affect women in their 70s a little bit different than a man in his 20s? As well as the two of you doing the experiments on yourself have you ever had other people from different backgrounds different ages etc. do the same things that you have done?
