Is there anything like N2Slin or other carb blockers that would work against fats? Sometimes I don't get to eat absolutely “clean” food, and it would be amazing to have such a supplement just in case.
To my knowledge, there is no such supplement, so it would be best to try avoid those foods. If you absolutely can not, then just don't think and at least enjoy them. It is pointless to stress about something you can not change.
