You might just not be that hungry. If you don't feel like eating a lot don't eat a lot. Just make sure you eat enough so that your body gets enough nutrition and energy to get by.
I usually have no appetite for the first 30 minutes after getting stoned. It's while the high is wearing off is when I start to get hungry.
I find if I'm already hungry or thinking about eating then getting high will amplify my appetite but if that's not already on my mind I'm just as likely to forgot to even eat if I end up getting focused on something else while I'm high.
