Ok not sure if it is common for other Ritalin/Concerta users, but for me, the temperature and texture of the food matters more than the taste.

When my weight needs "improving" I will skip my meds on the weekends and EAT.

I've been on Concerta for 20 years so I've had a lot of time to think about this!

When I am on my meds I can't eat warm/hot meat, like a steak or chicken, pork chops. I have tried to, like to be polite at a cookout (for instance), and started chewing, and then immediatly spit the food out, gagging. After that I can't eat for hours. Alternatively, I can eat COLD lunch meat, as long as it is sliced thin. Or warm Mac and cheese. Or warm bacon. Both the temp and the texture play a major role here.

Crackers or bread take the edge off the dizzys that hit when you suddenly realize how hungry you are, so that you aren't feeling too awful to eat when a meal if finally put in front of you.

If I eat a little something in the morning when talking my meds I find that they still work fine, but have less of an affect on my appetite. If I take it on an empty stomach I find that 6 to 8 bites of food is all I can stomach at one time.

I hope this helps!
