Vegetarian having hard time getting to calorie goal

Brown rice and oatmeal (the real stuff not the diet ones) both have a fair amount of calories (I have to limit them or I go over my calorie quota). And like others said, unsalted nuts.

I will try that for my breakfast and see how it goes. I really don't like eating eggs everyday. I am going to add more nuts in, just have to make my brain accept that they are ok and not fatty! Thanks.

Do you like sweets?

A scoop of icecream is another easy option. Coconut-based, if you go Vegan (So Delicious is the best brand, chocolate.)

I would try adding more high protein, high fiber foods. Frozen food is what is killing your sodium intake. High sodium makes you retain water, also. Instead of a bagel thin in the morning try a slice of whole wheat toast with almond butter on it. Almond butter has just over 100 calories per Tbsp, and it's delicious and filling.. That with some yogurt and a piece of fruit will fill you up, plus be more nutritious than your current regimen. I wouldn't worry about fat content as much as you are. Some fats are good for you and your body processes easily, i.e. nuts, dairy.
I've stopped buying most processed foods, and I overall feel way better.
Good luck!
