Can eating cereal that contains high froustuse corn syrup thats low in Cal fat sugar still cause weight gain?

theres only 3 and 4 grams of sugar in in the 2nd 3rd & 4th cereal thats Not very much HFCS. it will only cause weight gain if you eat an excessive amount meaning 3 or more servings. One or even two servings will NOT cause weight gain especially since you avoid it in all other foods. don't deprive your self
