Fasting for more meal flexibility than keto

"Well, if we are going to get really technical, I think a lot of the benefits [of fasting and time restricted eating] are overstated.  And a lot of the benefits are things that we have only studied in animals...  For example, a 16 hour fast in a mouse produces unbelievable results.  ...once you give a long enough period of time where the animal can ramp up the enzymes in the liver that are responsible for fat oxidation, they just become unbelievably efficient at metabolizing fat. 

We have to be careful though when we extrapolate that [to humans], because you and I have a very different metabolism than a mouse.  So I don't know if those benefits would extend.  So for me, what it comes down to is, it's just an easier way [than a strict low carb ketogenic diet], it gives me much more liberty with what I eat during my feeding window.  I don't have to be nearly as restrictive when I'm feeding if I have that period off.  I kind of hate being tethered to eat."
