That's just crazy talk. You keep going to the gym, and you'll get control of your eating! The more muscle you build, the more you can eat....and cardio also helps with burning off calories.
Don't stop the good part just because you're having difficulty with the the harder part. Remember: A little discomfort right now is much less painful than the regret you'll eventually feel if you don't ever take action. Discomfort can eventually be overcome, but regret will never go away.
You'll feel better in a day or two. You're just having a bad day.
