Annoyed to the point of tears!

For 2 weeks now I have been walking at 2,5 mph pace for 60 to 90 mins a day for the past 2 weeks and eating 1200 to 1300 calories a day and that damn scale hasnt moved at all. Im so disgusted and annoyed that I just wanna stuff my face full of crap and give up!! What am I doing wrong here?!?!?!

Bet you feel better! Am I right?
The first thing is your body is changing, but maybe the scales aren't showing it. Maybe you were dehydrated when you first weighed yourself, maybe you've eaten salt in the last few days.
You could try increasing your muscle by weight lifting to increase your basal metabolic rate.
You could try going low GI foods, eating more regularly across the day.
Certain foods help you lose, some foods help you keep the weight on:
'bad foods'
- alcohol
- fructose without fibre (soft drink)
- hydrogenated fats

'good foods'
- healthy oils (avocado, flax seed)
- brocolli
- garlic
- green tea

I supplement magnesium calcium, Vit E and healthy oils.
It is hardy to 'afford' the healthy oils but they help you stick to your diet. You can have the tiniest amount in a salad. You literally need healthy oil to help move the fat.
I'm totally against artificial sweetners and they can make you eat more fat, so best to avoid these too!
More muscle= more energy burned day to day.

Add me to the "eat more calories" group. I was at a huge plateau a few months ago. I upped my calories to my BMR (1550ish) and MFP told me I'd lose less than 1 pound a week. I averaged losing over a pound a week after losing a pound or two a month eating less calories. I haven't weighed lately... doing the Lenten no weigh in challenge... but I have to say that increasing calories worked for me. I'd at least try to net 1200 (eat 1200/day + eat back the calories you earned from exercise).

It is hard to give any useful answers without being able to see your food diary.

Are you logging everything you eat? I ask because some small things that many of us grab without thinking of it, add up very quickly. This goes for sampling as well. I know I am often tempted to take a small spoon of nutella without logging it, I can rationalize it as only a small spoon, but it is usually at least .5 of a tablespoon which would be 50 calories or more. That adds up through the day. Log everything that passes your mouth.

Are you monitoring your sodium intake? Too much can cause you to retain water which can hold you at a weight for a while.

How are you measuring your portions? If you are trusting that say 2 slices of bread are the size they should be, the reality is they are usually not accurate unless you are willing to weight your portions. My experience is that most of the prepackaged serving size stuff will actually be bigger than the amount that is listed, not always by much but it adds up. I suggest getting a digital kitchen scale. It does not have to be expensive. That will help you be more accurate in logging your calories.

Are you sure you don't have any underlying health issues or any medications you are on that may be hindering your weight loss. If you thyroid is not functioning correctly that will hinder weight-loss. Various medications will do the same thing.

If opening your food diary doesn't yield anything helpful, maybe this will help.

I just looked at your profile and saw that you'd lost 27 pounds before you joined MFP. Are you doing anything different now than you were then? I suspect that those who suggest you need more calories are onto something. You might want to bump them up a little bit and see what happens.

You might also want to look at *what* you're eating. For me, if I eat too many carbs I can't seem to lose weight. If I eat too few then I'm sluggish and have no energy to work out. I have found through trial and error that there is a certain range for me that is my *sweet spot* so to speak where I can gradually lose weight but still feel good. (Typically between 100-150 for me net carbs, more if I'm working out heavily.)

Most of all, don't give up! I've been on here since January but have been working on it since August. In all that time I've only lost 16 pounds! I have started losing more inches lately though and know that eventually the scale will catch up. (I've been weight training so I know it will be slow losing for awhile.) Take your measurements, take pictures and take a deep breath. If you quit you will never lose the weight. Hugs to you.

Do you have more energy than you did before? Are you sleeping better? Are your clothes fitting looser? If you answered yes to those just be patient. I'm not a professional, but muscle weighs more than fat. If you are working your muscles more and staying within your calorie needs the weight will come off. More muscle also burns more fat even when you are resting.

don't give up! that's what happened to me, too. and i was told (and also realized) that i was doing too much too soon. i've been sedentary before i joined MFP and decided to finally start exercising. i felt too giddy to lose weight, i walked for 30 minutes everyday for 2 weeks was conscious of my calorie intake but still did not lose a single pound! i changed everything especially my mindset that weight loss will happen immediately. i realized our body also needs rest so i exercised only at least 4 times a week for 30-45 minutes each time. i also started lifting light weights. so far, they're working. in here, it's still 0 weight lost because this is a new account i created but i've already lost 6 lbs and my old pants are now a little loose.

just keep going!

I agree with everyone else. Don't give up and I know you don't really want to...you are just really frustrated which is a normal.
I also agree with the people that say you may not be eating enough calories, your body will hang onto everything if it thinks it is going into starvation mode.
Another thought is: When you start to exercise you start to build muscle and muscle weighs MORE than fat but in the long run it burns fat long after you are done exercising. Muscle is the gift that keeps on giving.
Also I recommend an exercise you really enjoy or look forward to, though I walk too...I love my Wii and I spend hours on it at a time, to the point I feel guilty having so much fun and getting in so much exercise in at the same time!
Hang in there and know there are alot of us out here in the same or similiar prediciment.

You aren't doing anything wrong. You just need to keep going. Can you walk a little faster? Or for longer? Keep building up the stamina and you'll be able to do more, and then the weight will start to drop off.
