How much is your recommended intake, in calories? Are you used to eating very small amounts, say under 1000 calories?
Unless the calories set for you is way too high, due to some mistake, it shouldn't be that difficult to eat the food--the lowest amount recommended is usually 1200 calories, which really is the least you should be eating for health, unless there is some other factor, such as, you are really, really tiny, bedridden, etc.
Also, you do not have to eat the foods that Spark People suggests; I never use the meal plans; I'd be bored and dissatisfied. Work on eating the calories recommended using foods that you like and that are (mostly) healthy.
