You are right, he added starch to prove his hypothesis. There actually isn’t a reason to add it, other than the fact, that you don’t want to do keto. I have not added starch nor do I currently plan to ( I may test it out in the future and report). I prefer either the low carb or low fat approach (both with saturated fat). The middle ground is sketchy for me.
I mean, most junk food contains a combination of fats and carbs that override our satiety signal.
How many foods in nature contain a mixture of fats and carbs? Mothers milk and that’s basically it. The baby needs to eat/drink as many calories as possible to grow. It’s basically force feeding with a ratio of carbs and fats that overrides the brains satiety signals. Look at the label of every junk food item, just a shitty ratio of fats and carbs.
On top of that there is another thing that worries me if you add carbs. We all know the theory behind ros, but the question is, do all the cells become insulin resistant or just the adipose cells? Do muscle cells become insulin resistant? Because if they do that could lead to higher blood glucose levels and increased glycation, which is far from a good thing.
