Am I eating enough a day?

Short answer: no.

Go here and figure where you should be with a -20% deficit: http://scoobysworkshop.com/calorie-calculator/ I put in your info with the moderate in the exercise section, and it says 2142. If you are actually 18? Of course, this includes exercise in the equation already; mfp does not, and that's why it adds it.

It's alright to be under your daily calorie goal but not by too much cause then your body will start burning muscles to compensate for the lack of calories! Anyways, hope this help & best of luck!

It looks decent enough to me, calories-wise anyway. I didn't really look at the foods. I would try my best to make goal every day, either like 100 under/over max.

Agree with everyone else. You aren't eating nearly enough, but it's because your numbers are wrong. Go to fitnessfrog.com or some other site (google TDEE) and figure your daily expenditure. Then go about 1000 under that to lose fast, but keep in mind that you never want to be below 1200 and you may need to start closer to 500 a day under and then eat less if it's too slow. You are young, so shouldn't be too hard to lose if you are careful unless there is an underlying health problem. Good luck!

Seriously? Are you full or hungry? If your full then your eating enough, if your hungry then eat some more. I say your eating enough. Don't listen to all the BS about your body eating your muscles, won't happen until your body fat gets below a certain percentage so your okay there. As long as you got fat to burn your not going to eat away at those muscles.

YOU have to decide for YOU if your happy with your calorie intake and how much weight your losing a week. I'd wait a bit longer before increasing your intake until you see what your loss is going to be like.

My TDEE is 2678 calories a day and my daily calorie goal is 1320 calories.

If you TDEE is 2678 a 20% cut from you TDEE is 2142 - you need it increase your intake goal to above your BMR at a minimum. Use the raodmap to find that number and get above it. use you measurements to find you body fat % so the calculation reflects your lean body mass. You can increase you intake by 100-200 a week till you get above your BMR and up to the 20% range. 1300 is almost a 50% cut - even if you were obese the recommendation is only for a 30% decrease in calories. With your activity level you have the potential to be causing long term harm to you growing body. You need those calories and nutrition to build the bones and body you will be using for the next 60 years. Don't cheat your future self......

If you know you activity schedule build your extra calories in your meals as you go a long. You can add more meat to your portions, have good fats - olive oil in your dressing, nuts and nut butters, fuller fat dairy - there are plenty of ways to get more calories for less volume of food.

I'm 18 years old, yes, just turned. My TDEE is 2678 calories a day and my daily calorie goal is 1320 calories.

I don't want my muscles to start eating themselves or anything, I just want to lose the weight but understand eating too little can be negative towards that, but at the same time I don't want to eat too much because that's also bad.

I don't feel starving or hungry at the moment, my stomach isn't howling for something to be put in it (which is usually my problem at the end of the day when I'm a few calories down - I can't eat them because I don't feel hungry / like I need to).

I've got my weigh-in on Friday so I'll see if I've lost anything then, then I'll have to adjust things to fit me. Otherwise yes, I'm just worrying. I wanna get this nailed the right way so I can continue on doing it because I really do feel great lately just from eating better and not putting junk into my body.

(Also thank you for the road map, it was super helpful!)

Assuming 2678 is actually within your true maintenance range, then netting below that will not lead to weight gain unless you have a medical issue which causes it to happen such as hypothyroidism or insulin sensitivity. Take the advice of everyone and assume a sum deficit of 20% to 25% max and establish it however you wish. It is, however, preferred if calories less from eating makes up the bulk of the deficit if you are engaging in exercise. If you do not exercise, then simply reduce calories eaten by 535. If you do exercise, eat 300 to 400 less and exercise calories will be the remainder.
