NEED YOUR ADVICE PLEASE.

How are you calculating your exercise burns?

Are you eating all of those calories back?

Just because food is "healthy" doesn't mean it will make you lose weight. It's the calories that matter. Seeds, beans, and whole wheat products can be calorie dense.

22 pounds in 1 months is quite a lot. Probably not something that you can keep doing, frankly. So after such a large initial loss, perhaps its time to re-consider your strategy.

You say that you have stopped losing. How long has it been since you saw a loss? If it has only been one or two weeks, then, I'm sorry, but that is perfectly normal. There will be weeks when you lose 1 or 2 pound, and there will be other weeks when you lose nothing. There may even be weeks when your weight seems to go up, if you are retaining water. Sometimes, a large initial loss is even due to water weight loss, so it may be the case that your fluid levels are just fluctuating now because part of your apparent loss has been water and not fat, and your lack of loss this week is actually just your body retaining a little more water.

However, I have to mention that I'm not sure its either healthy or productive for you to be eating 1300 calories per day and working out for 2 hours each day. (Since you say that you have been weighing everything, I'm assuming that we can be confident that the intake you report is correct.) You don't mention your height, but at your weight, you could certainly be eating more and still losing weight. Many people have reported that they actually lose more weight when they eat enough to be satisfied and to fuel their exercise routines. You aren't doing that. I'd start there. Go ahead and get this site to calculate a daily intake for you based on your height, weight and activity level. Try that for 2 to 4 weeks, and see if anything changes. And remember, you just can't tell what is working by only looking at any loss or lack of loss that happens over less than a couple of weeks.

you lost 22 pounds in a MONTH?

Anything more than 2 lbs a week would be unsustainable (and not to mention unhealthy) for most people....

I started with 110 to lose and have lost 70 in 8 months - which is staggeringly good (and not expected to last). Some weeks i lose, some i gain, some stay steady, but if I were you I would not expect to maintain that rate of loss, and I honestly would be concerned about 'burning out' and gaining weight back....

remember- you didn't gain it all in 2 months, you certainly wont lose it all in 2 months!

Advice about what exactly? How to lose another 22 lbs in a month?

I just want to say I totally respect your walking and running exercise. Just a thought, but several of us with knee or back issues add in some swimming or pool workouts rather than beat ourselves up running. Not sure that would be an option for you until you get down a bit more so you don't end up damaging your knees.... It's just a thought. Best wishes!!

A number of things pop to mind reading your posts:
1. Knee pain - First, check your shoes. A good pair of shoes is imperative. Second, it may well be that you are overdoing the walking. If you have been idle for a long period of time your body simply may not be ready for an hour or two daily walks. The body does adapt, but it takes time. Trying to beat biology here is apt to lead to injury and/or frustration. Try a lighter walking load and increasing the stress (i.e., rate, time, or distance totals) gradually.
2. Exercise calories are often wildly overstated. Do't trust your machine's numbers.
3. Exercise certainly increases your caloric burn, the main factor in weight loss is diet. Weight loss will come from eating at a deficit.
4. Scale measurements of weight loss are not 100% fat loss. Those first 22 pounds is staggering and feels darn good, but it may well be that a lot of it was water. Early drop in pounds is not unusual because of this, but at some point you should try to get to a more sustainable (and healthy) rate of loss. Even after initial water loss, each pound of weight loss isn't a 1 to 1 ratio of pounds of adipose (fat tissue) lost. You will lose lean body mass as well. Nothing you can do about that, but you can limit it with appropriate exercise.
5. plateau can be caused by a lot of things. You said you are weighing and measuring food and logging dilligently. That is good. But starting the new exercise program could also result in water retention (muscles do that) or even some new muscle gains (this happens with newbies, but won't last). Another cause could be high sodium levels. If you are taking in a lot of sodium, you could be retaining water. Also, hormones can cause water issues (especially in women). But, no matter the cause, plateau's happen and so do some ups. Your body is a complex machine and there are lots and lots of variables here so, again, the math isn't going to be a perfect.
6. Stop looking at the scale for all your progress. There are many NonScaleVicotries to be had. One of the first places I noticed weight loss when I started was in my hands, forearms, and calves. We want it all to come off the belly, but that isn't how it works. And, if you think about it, you should see it in the extremities before you see it in the problem areas.

The very best tools you have in your arsenal are persistence and patience. Stick to the logging, weighing, and measuring and the weight will come off over time. Stay the course and before you know it you will see change in the mirror, in your clothes, on the scale and in the compliments people give you. Patience and persistence are the key.

My sister recommended MFP when I told her I was frustrated about not being able to exercise due to bad knees. After losing weight and gradually strengthening my knees, they are much better now. I have Asics gel sneakers. I walk on trails in the woods rather than on pavement. I swim. I do these exercises regularly:

Woohoo, way to go! We will soon be calling you waterbaby instead of torchita.
Have fun swimming, it will be so much easier on your knees.

Cheers, h.
