OK, Keto has worked for me and I am at my new (lower) goal weight and all the blood numbers have improved…stopped taking statins and had to decrease my heart meds substantially. I drink (ahem) “several” diet dr. peppers a day, diet coke when I can’t get them. Two of my keto friends are at opposite ends of the spectrum on this…friend1 arguing aspartame increases insulin levels and everything in a can of DDP might as well have been delivered to me (and to friend2) by Satan … while friend2 drinks more diet sodas than I do (which means a lot) and poo poos the doctrinaire attitude of the macro-counting MCT oil swilling friend1.
Clearly they are not an impediment to weight loss for me and frankly I am worried more about the caffeine than the aspartame… but you people have done more research here… at least they have no PUFAs
