A coke is ~10% of your daily calorie needs.*  It&#x27;s not that exercise is ineffective it&#x27;s junk food has stupid high calorie counts plus it&#x27;s easy to digest.  On top of that most Americans have an incredibly lazy lifestyle.  If your extremely active and stick with actual food eating enough can feel like a chore.<p>PS: A coke is also 8 to 24 oz which is a fairly wide range.
