I wish i had this problem
MFP, just lowered my calorie intake by 70 cals, and I instantly started looking for ways to burn 70 more calories a day.
I'm currently eating about 1500-1600 a day with a net of 1240 after exercise. My extra calories usually come from Olive Oil, cheese, organic peanut butter and my occasional treats.
If you're feeling full on 1100 calories, then I think it's okay to maybe save your extra calories for a once or twice a week treat. Or maybe treat yourself to a higher calorie salad dressing. Or add some cereal to your yogurt.
I think the most important thing is that you feel satisfied with your meal plan and don't feel like you're missing out anything taste or nutrient wise.
Good luck!
