I’m not sure if the starches cause blood sugar imbalances. I think for me it’s the amount of food I eat at one sitting, and usually those starches are accompanied by meat, or cheese, or some other protein and plenty of fat and salt that cause me problems. Which is part of the problem if you follow the food palatability theory, which I think is very probable. I think it’s Guyenet who talks about that a lot, not Masterjohn, although he may.
Also, it’s very individual as well Dutchie. Are you saying melted cheese is a sugar/fat combination? To me, that’s just mostly fat and protein. When I think sugar, I think of the OJ and milk that I drink (about 1L per day of each). I’m on over 300gms of carbs per day (I’m female) and sometimes close to 1kg of potatoes and I’m losing weight. I generally eat less than 2 grams of PUFA daily and the rest of sat/mono fat. So for me personally, I don’t feel like sugar is fattening.
I agree that if you ate plain bread of pasta, it would be incredibly unrewarding and would probably help you lose weight effortlessly.
