I strongly advise against this, based on my own experience. I cheated with one meal — I had a slice of garlic bread and an order of fries. This was about two months into my low-carb journey. I felt absolutely wretched the rest of the afternoon — headache, stomach ache, foggy "I need a nap NOW" feeling, etc. And I gained 6 pounds, which I had to work for two weeks to lose again.

Totally not worth it! You've heard it said "Nothing tastes as good as thin feels," and it's absolutely true.
