Is Health Playing with The House's Money?

People tell me all the time that because they work out they can now drink alcohol or eat fast food or decadent desserts or splurge every weekend. And they can. There is no law stating they cannot. At least, no written law. Still, they justify their vices with working out as if working out is all the body needs to maintain health. They believe that because they work out that they can now go and eat any way they want because they have nothing to lose. Because they are playing with the house’s money.
