MyFitnessPal tells me I'm consuming to few Cals

I love this system but the advice at the end well isn't advice it tells me i'm eating to few calories, i'm not hungry, so what does it want me to eat more food?, losing weight is the goal im not going to eat unless im hungry and im not going to changed what i eat just because the calories are too low.

OK I'll bite

No the goal is to get healthy. Part of that is losing weight (if you are overweight). Being healthy also means eating enough to maintain a healthy body

Your super-low calorie strategy may be working for you now since you're fairly new to this (and appear to have a lot of weight to lose), but nobody is going to be surprised if you're on here in another month saying your weight loss has stalled and you don't understand why. The goal should not be to lose as fast as possible, but to do it slowly and steadily, in a manner that's conducive to a sustainable lifestyle. Good luck!

And just had a look at your diary. There's no reason for you to be eating that little and be full. You should probably visit your GP and eventually a dietician to rule out health problems and learn about what and how you should eat. No way 600 calories is filling you up for the day.

I would also have another look at how consistent you are with your logging. Are you really logging absolutely everything that passes your lips? What you think is just a little bit here and there can mount up quickly and could explain why you aren't hungry.

If you really are being accurate with your logging the only explanation I've got is that your hunger sense is off. I'd be climbing the walls if I was eating as little as you are. As other people have said it's important to get at least close to your calorie target as it makes it much easier to get the nutrition your body needs to be strong and healthy. Dropping weight quickly is also much more likely to leave you with rolls of loose skin instead of a nice firm stomach. Finally if you want to keep the weight off you need to think of this as a life long change instead of being a short term fix.

MFP is telling you that because it's the truth. An adult male needs 1800 calories a day just to properly maintain body functions. Women can get away with less because they generally carry less lean body mass than men. You may also be able to do 1500 calories as an obese male for a while but it has to be with an eye to good nutrition and your diary is anything but.

You may think that you're full but that's a mind game. It will catch up with you and you'll be ravenous, probably binge and blow the work you've done not to mention things like your hair falling out and organ damage.

Educate yourself on BMR and TDEE (Google will help you), buy real food and learn to prepare it and set yourself up for a healthy life.

Eating low one day will not harm you but if you're doing it many days in a row and still are feeling full, you're probably not logging right. But be honest with yourself about 'feeling full'. Is what you're really feeling that you'd rather lose weight really quickly and you feel like you can suffer through the deprivation to get there? Usually that plan backfires pretty quickly.

It's not just one day; it's every single day. :noway:

It tells you that because you are consuming too few cals. :flowerforyou:

I leave the diary checking to others. It tells me nothing except what someone felt like logging.

Hunger cues aren't necessarily trustworthy. Once you regularly under-eat you stop feeling hungry, which is why anorexics report that they aren't hungry even as they are wasting away.

Use your brain, not your stomach, to determine your energy requirements.

I personally do not think you should eat if you aren't hungry, but I would guess that you are probably eating more than you think you are.....sometimes our estimates for how much of a portion we actually had are off

My diary says this too, it was frustrating but I just leave it, I discovered the only way it is going to tell you you are eating enough is if you are bang on 1200 or above. My goal is to not go above that, and well it is working for me so far

Except for the binges. That's what happens when you under eat.

I'm the first to say don't eat if you aren't hungry, but if that's how it's going EVERY DAMN DAY, then you need to look at your hunger queues and go see your doctor as you have bigger issues. Will there be a day here or there where I got under 1500 or so and possibly get that warning? Sure, but if I get it more than 2 days in the same week I know something isn't right with my eating habits.

Looking at your food diary (if it is accurate) you are basically starving yourself. As a 19 year old male you should be eating way more then 600-800 a day. Eating such small amount of calories s will have all sorts of unwanted consequences. Yes you will lose fat, but you will also lose muscle, its likely to mess up your hormones, leave you with no energy and generally feeling like crap If you do reach your weight goal’s your going to look unhealthy and feel unhealthy.

However if I had to put money on it I would bet you cannot sustain eating at such a crazy low level.

You may know more about this than I, but according to Marya Hornbacher who is a recovered anorexic who wrote "Wasted" anorexics will tell you they are not hungry, but they are lying. They are out of their minds ravenous all the time. For what it's worth.

.

That may be true. I can't find my original source (and it's been a long time since I read that) just a bunch of anecdotal evidence from recovering anorexics and people who do various types of fasting. :flowerforyou:

Anorexics will bounce between both states because their hormones are that dysfunctional. Some moments they won't feel hunger while other times they'll be ravenous but ignore it.

Sources?
