Diet Suggestions During Head and Neck Radiation

Radiation to one's head and neck poses a challenge to eating enough. Radiation treatment also raises one's metabolism, so more calories are needed, otherwise weight is quickly lost.

When I had radiation, we wrote down everything I ate or drank every day, along with the calories. I had to eat at least 1500-2000 calories per day. Weighing myself every day also helped to motivate me to eat more. It's best to set a goal of the weight you do not want to drop below.
