I read through the sample, thank you for referring it to me. I am somewhat familiar with keto/low-carb diets.
In reviewing Gary’s work, I did come across the study he did under Nutrition Science Initiative, and how the results didn’t support his claims. Have you had a chance to look into this?
(Aside: my dad is around your age, and has not yet quit smoking despite science since he doesn’t have any adverse effects. Be well!)
