I don't eat enough calories

Bump up your calories with foods that are dense, like peanut butter, butter, oils, nuts, and cheeses.

Your diary isn't open and you haven't really given us enough info to go on.

That said, milk is a good option, provided you aren't lactose intolerant.

The answer is that it might be bad, depending on how much you're actually eating and how you set up your goal on MFP.

Some good advice on foods to eat up above. Don't forget that it's okay to drink your calories too, as long as you account for them. Fruit juices, lattes, protein shakes & smoothies. There are lots of ways to increase your calories without adding a lot of extra food into your stomach.

I have this problem every now and then. I try to keep calorie dense food out of my house so I'm not tempted. If you're having this problem on a daily basis, maybe stock up a little on calorie dense food.

You only have two completed days, but are they accurate? Because no, no, no, 400 calories per day is not okay! Not if you're an adult human being who wants to keep being alive. Neither is 930. Please go see a doctor.

Depends. If your BMR is say 1200 and TDEE 1800, and you just can't fit the 1800 and manage 1400, that's alright. However if with the same stats you're subsisting on 900 a day, no. You should never net below your BMR unless you're extremely obese and might otherwise die from health complications.
Peanut butter is a great idea, nuts as well. Dairy products also are great and any kind of good beef roast or sausages.

Wow. The myth has now evolved into DEATH from eating under your BMR. Absolutely amazing.

I think you misread. If you are obese and may die of health complications, eating under your BMR isn't recommended. Not that you will DIE eating under your BMR. If you are so obese and have health complications that may kill you in the near future unless you have an immediate drop in weight, then under a physician, eating a VLCD may be warranted according to some practitioners.

As a general rule, it's OK to eat when you are hungry and not eat when you're not hungry. The issue is that if you are eating too few calories on a regular basis, then your body adjusts it's metabolism to account for not getting enough energy. This will affect your appetite and you won't be hungry even when you are not eating enough food.

If you haven't already you should calculate your BMR and TDEE (you can find many sites that will calculate these for you).
Here's one that uses a few different ways of calculating TDEE

I usually always just set my activity level to sedentary even though I work out multiple times a week. I think it's easier to do the math if you know what your TDEE is when not 'active' and then that way when you work out...all those calories are ones you are burning and it doesn't matter if you miss working out (ie. if you say that your activity level is high and you don't work out for a week or something, your calories will be off)

So, once you know your TDEE, then you want to set your calorie goal to ~10% less than that. That should be the number of calories you shoot for in a day. When you log your workout (calories burned) MFP will automatically add those calories to your daily goal. You should eat them, or most of them at least. Now, if there are a couple days here and there when you really just aren't hungry then it's not the end of the world to be under your goal, but it should not be a regular thing. You may gain a little weight at first while your body adjusts it's metabolism rate.

As for what you can eat, for the time being since you aren't 'hungry', what others have said are good suggestions. Calorie dense foods that don't 'fill you up' but have lots of calories for a small amount. Others have made you a good list of foods....I'd add dried fruit. If you can get it with no sugar added, that'd be great. But dried fruit is calorie dense....Dried cherries are my favorite.

Good luck!

I have the same problem. I don't like to eat for the sake of eating, generally I can hit about 1200 a day but because I'm exercising my net is crazy low. My average this week was 366 net I've managed to up it to avg net 506 by having slightly bigger portions today, but I'm finding it really hard to keep up there... I honestly don't think I can reach my BMF without almost doubling what I eat, and I don't want to be doing that when I don't feel hungry for it.

Suggestions welcome for me too please!

S.

If your net calories are crazy low then maybe eat some of the foods that you ate before you decided to lose weight. Failing that there are many calorie dense foods to add in to your diet such as olive oil, nuts and nut butters, avocado etc The calories do add up pretty quickly

In because if the OP's diary is for real.... things are gonna get real.
