Part of the magic of low carb weight loss and maintenance is the calorie control that comes from eating the rare (better) low carb products, that are lower in calories than their full carb counterparts. It’s not the 7 net carbs in the low carb fat-free toritilla that make it terrific, it’s the 60 calories, compared to 120-200 calories in a normal tortilla.. It’s not the 2 net carbs in the whole grain bran crackers (crispbread) that make them work, it’s the fact that the crackers have 12 calories, compared to 75 calories for full carb crackers.. It’s not the 4 net carbs per half cup of the low carb ice cream, it’s the fact that the ice cream has 90 calories per half cup, compared to 170 calories per half cup for Haagen Das.
