How to Avoid Gaining Weight During the Holidays
Dr. Cindy Dallow PhD, RD 11/3/2025 One of the most common questions I get as a dietitian is, “How can I prevent gaining weight during the holidays?” Let’s be honest, the stretch between Halloween and New Year’s can be tough, even for the most dedicated fitness enthusiasts.
