Nonsense. Tell this to humans that die when their blood glucose is insanely high (500mg/dl), go into DKA and they are SKINNY!!! You’re suggesting 20 calories can make you obese because it raises blood glucose lol! 3-5 grams (12-20 calories) of a mild-glycemic index carbohydrate can send your blood glucose well above 120mg/dl and you would not gain weight because of an extra 12-20 calories. Additionally, 1,200 calories from fat (133 grams of fat) will not spike your blood glucose until 5-12 hours later and you you can gain weight, but that signal is lost because the rise in blood glucose happens 1-3 meals, or even the next day after eating the high fat meal. Blood glucose is VERY important but not predictive of weight. Diet, (the amount and macro composition of calories) is predictive of weight and exercise is predictive of weight. The are other factors, but those are the main predictors.
