"Would specific food purchased to weight train as a personal trainer be a business expense to the trainer?"

What food and who is eating it?

Example: Your client, the trainer, buys food to sell to clients. Yes, that would be COGS and Income. No, anything the trainer eats is Personal. We all need to eat. Unless there is a medical prescription for some special limited diet foods, there is no Write Off for personal food.

Are you doing any of your own research for IRS regulations? Or, just asking the Web, taking the easy way out?
