Victoria's Secret model, Erin Heatherton, follows a gluten-free diet but admits she allows herself cheat days.
"I love fish and chicken and I eat bacon too sometimes," she said. "I'll cheat on meat, cheese. I workout and eat right, I can't be too hard on myself about making mistakes and whatever."
Heatherton revealed that the best diet advice she received came from Cindy Crawford.
"She said it's really not always about working out; the most important thing is about what you eat. That really changed my perspective."
