Is it bad to eat less than 1200 Calories??

If you really focused on trying to make the protein goal, your calorie goal would probably work itself out. Most high-protein foods (milk, cheese, nuts, meat, eggs) are also high in calories. There are also plenty of nutrient rich foods that give you calories. Many fruits, for example, are loaded with them. I bought some clementine cuties (which are EVERYWHERE around the holidays) and was really surprised when I input them how high calorie they were. You would not have to eat junk to get there.

My rule is to try to get within 150 of my calorie goal, over or under. If your energy level is ok and you do not feel hungry or sick to your stomach, you are probably ok. But you do want to be careful not to under-eat. That is just as bad for you as over-eating.

It really depends on your current height / weight on how good/bad it is for you. You can get the protein by eating boneless skinless grilled chicken breast, which is almost pure protein calories. Also, 100 is a lot better than 300. If you're trying to lose weight, try to get closer to 1200 and then exercise a little more to get the same net result.

It's better to try and be close to a goal number when loosing weight. If you find yourself going under, keep some greek yogurt and almonds in the house - both of these are really healthy and can get your numbers up with a small amount of food.

Another quick, good thing to eat is a smoothie:
1/2 cup milk
1/2 cup fruit (or like, 1 banana)
3-4 ice cubes (if you want)
1 tsp honey

blend

You just started so give it a few weeks to find your likes and dislikes and then enjoy the journey, it's the rest of your life!

Thanks so much everyone! I'm 5'2 and this morning i weighed myself at 135.9. I just started dieting last Tuesday at 140 and this seems like way too much too fast. I don't want to be unhealthy or anything!

Keep in mind you'll lose more initially. Don't worry, it WILL slow down (it's happened to all of us!).

You do need to be careful about eating too low. Your body needs a certain amount of calories just to function (use the Tools section to calculate your BMR, which is the amount of calories you'd burn if you just laid in bed all day). Eating below that can cause serious health issues. If you are exercising, you need fuel for your body.

I am 5'4", and I'm eating 1600 plus exercise calories (I make sure I don't net less than about 1400; my BMR is 1479). The pounds are still slowly coming off. Eating too little can actually cause you to hit a plateau that is hard to break.

As pixiechick said, keep some nuts and yogurt in the house. You don't have to eat crap to get the extra calories. You could also allow yourself a treat sometimes, too; I like Skinny Cow ice cream bars and candy, as well as Snackwells cookies. They are in pre-measured packs of 100-150 calories. It helps me to not feel so deprived (I have a major sweet tooth!).
