cant fuction on the calories recommended

Do you have it set for 1 lb/week weight loss, or something higher? You could try changing your goal to slower weight loss, even just temporarily. I eased myself down and it's worked so far.

Just a thought, I'm not a nutritionist, but your hunger might be related to nutrient requirements. Might be you're not getting enough fat, or protein, or too much sugar, not enough iron, etc.

Or maybe it's just that 1200 isn't enough and you need to eat more. Above all listen to your body, it knows what it needs.

On 1200 calories you have to make sure you are eating back whatever calories you burn during the day. When I was at 1290 I was getting muscle aches and was very spacey. I also stalled on my weight loss, so I decided to move up to 1500 calories a day and i feel SO much better and I can exercise harder.

A safe area to be in would be 20-35% less of your TDEE to lose weight.

Here's a simple calculation.
Estimated TDEE = Multiply your weight in lbs x 15.
To lose weight = Subtract 20-35%
Follow plan for 3 weeks.
Adjust accordingly.

Example:
Assuming you're 143 lbs.
Estimated TDEE = 143 x 15 = 2145
20% of 2145 = 429 --> 2145-429=1716 (0.86 lbs per week)
35% of 2145 = 751 --> 2145-751=1394 (1.50 lbs per week)
In this example to lose weight, eat between 1400-1715 calories.

MFP doesn't use percentages. They base their loss by lbs per week.
3500 calories = 1 lb. 3500/7 = 500 calories per day
7000 calories = 2 lb. 7000/7 = 1000 calories per day
2145-500 = 1645
2145-1000 = 1145
As you can tell, using poundages for a person with such a low TDEE wouldn't be a great idea, because a 2 lb loss per week is detrimental for a person with such a low TDEE.

If you had a higher TDEE of 2700, it would be fine to subtract 500-1000 calories per day.
2700-500=2200
2700-1000=1700

But a better way, would still be to use the 20-35%.
20% of 2700 = 540 --> 2700-540=2160 (0.72 lbs per week)
35% of 2700 = 945 --> 2700-945=1755 (1.25 lbs per week)
In this example to lose weight, eat between 1750-2150 calories.

****The important thing with all of these calculations is they are estimates.
****It doesn't really matter what numbers you pick.
****Pick a number and stick with it for 3 weeks.
****Based off your RESULTS, either increase or decrease.

****If after 3 weeks, your average weekly fat loss was:
--Less than 1 lb/wk -->Reduce your calories by 10%
--1-1.5 lbs/wk --> No Change
--2+ lbs/wk -->Is there performance loss?-->No (no change), Yes (Increase calories by 10%)

I'm just staring week 3 and I sometimes have the same trouble, but I trust my body more than I trust numbers in a program. Some days it's as simple as eating a tablespoon of raisins, or a few peanuts or almonds. Other days I need a sandwich to feel satisfied. Experiment with your diet and find what works for you! It might be good to also take a look at what you're eating and make sure you're hitting all of the nutritional bases.

I started out at 154 lbs, and on 1200 cals a week to lose just under a lb a week. And I was starving. Properly, miserably starving. I don't know how people do it long term. I went up to 1360 cals a day after a couple of months and was a lot happier.

You should open your diary when asking for help.

Eat back your exercise cals.
Eat lots of veggies.
Increase fat &/or protein.
Drink water.
Eat whole grain starches.
Eat nuts.
are you truly hungry or wanting to munch out of habit?

I think on 1200 cals, most people are properly hungry. Not wanting to eat from habit.

to open your diary go into your privacy settings on your account plus i have been doing mfp since january although it looks like less as I did not log when I was away due to no comp' however I started at losing half a pound a week and it worked I was on 1700 odd calories a day and I have lost so far slowly and have now changed over the last couple weeks to a pound a week . Stay strong it is one of the best places to lose the weight especially with the support all the best

diary open only three days in it though cuz im new but i think im gunna add 250 extra and work my way down

You are eating high calorie low nutrient foods all the time. For example:

Lean Cuisine - Pepperoni Pizza, 1 Pizza (170g)
Replace with:
1 Whole Wheat Pita, 1/4 C Mozzerella, 1/4c Pizza Sauce, 2c of veggies

Pbj - Pbj, 1 Sandwich
Replace with:
Apple and 2tbs Peanut Butter with 1tbs Water (PB and Water for 30 Seconds).

When I set my weekly weight loss goal too high (1 lb or more per week), MFP also recommended around 1200 net calories per day. I was miserable and I could tell my body needed more fuel, so I upped my daily net goal to 1450. Because I exercise a lot, I actually end up eating a total of 1650-2000 calories per day, but I try to net at least 1450. I'm still losing weight at a rapid pace, but I feel so much better. Don't be afraid to increase your caloric intake until you find something that feels "right" for you. You're not in a race to meet your goal weight! You're much more likely to be successful if you have a plan that you can sustain.

MFP recommends that I only eat 1200 per day too. I couldn't function on it and found that I don't lose very much when I eat only 1200 so I upped my calories to a variable between 1500 and 1800 per day. I do not eat my exercise calories back though unless my NET calories are below 1200. Try for a few weeks with like 1500 calories and see how you do. You may be surprised at how it works

You haven't got many days filled in yet, but what there is says you're not eating well. I'd cut out the ready meals - you'll find homemade food without all the additives a lot more filling and you'll be able to have more of it. Try and get your protein intake up. And as others have said, you need to do the maths around your BMR and TDEE. You sound like you're more active than just sedentary and I doubt 1200 is enough - I'm losing on 1700 + eating back exercise calories, although I'm tall

I would recommend three things.
1. Make sure your drinking at least 8 glasses of water daily, and try to drink one before a meal.
2. Add to every meal some vegetables, try to avoid butter or dressings if you can. Vegetables are a great source of nutrients, can make you feel Fuller without the excessive calories. Or do a veggie salad with every meal with fat free very low calorie dressing, you can usually find these at your local grocery store in a spray bottle.
3. If you want to eat more, then do it. Just make sure you burn off the extra calories before the end of the day.
Good luck

Short and simple. Exercise more and you'll be able to eat more and still lose weight.
