Indulging too much on the weekends while staying super strict during the week

Restricting your food and then overindulging is sabotaging your healthy eating habits, according to Dr. Apovian. She pointed out that you can make up the calories you didn't eat during the week in just one indulgent night.

"Overdoing it on Friday and Saturday nights, you can get in all the calories that you painfully did not eat the whole last week," she said.
