If I do the same exercise all the time does it stop becoming useful for losing weight?

Increasing intensity of workouts burns more calories. Yes?0 -
Maybe I'm just being impatient, a lb is still losing even if it did take two weeks. And yep I thought you'd burn more calories if you pushed yourself a bit more0

I know when I push myself I burn more calories unless Im crazy and just seeing things lol

I believe the point is that if you walk a mile you will burn X calories, whether you walk it fast or slow.0 -

Not sure you have quite got it...
Walking for an hour at 2mph will burn "this amount of calories".
Push yourself a bit more and walk for an hour at 4mph and you will burn twice as many calories because you have gone double the distance.
It's the distance not the "pushing".
But thinking that exercise is the biggest factor in weight loss is a mistake. It helps but it's not the major player.0 -

No it will be mostly the same, unless your weight has changed. There are a number of factors in the "calories in, calories out" equation. People tend to draw false conclusions from their observations.

If you walk all the time, your body adjusts and you burn less and less as you get into better cardio vascular shape. I have seen this with my running. I wear a heart rate monitor a fair amout of time, and I have seen as example; a year ago a 5k at 8:00 per mile burned more calories than a 5k at the same pace today. My body has adjusted and if I want to burn more cals, i need to change up my workouts, or work harder for longer. Try adding in some body weight "lifting" for a few weeks, and then jump that up to using some light weights. Plus keep walking, and throw in some running when you can. Good luck, and great job!!
This is incorrect. What you are observing is the inaccuracy of HRM technology, not a change in physiology.
If, via training, your fitness level has improved, then a decrease in heart rate for a given exercise workload DOES NOT mean a decrease in calories burned. The drop in the number on the HRM means the HRM settings are now wrong.

That is pretty much how I understood it. I can burn (according to MFP) 120 calories walking one mile at 2 mph; 118 walking at 3 mph; 122 at 4 mph

NO.
(Assuming you stay the same weight)

No I don't think I've quite got the whole weight loss thing because I'm not doing it very successfully at the moment lol. As for the distance thing though, I walked for over 8 miles the other day, I did 7 yesterday, I'm not sure I could fit in any more. I'm trying my best to make diet the more important part and there's only one day I haven't hit my calorie goal. Maybe I should eat less than 1555 calories a day, that's the amount I got on a BMR calculator. Perhaps I should go for 1200 calories a day instead like my fitness pal originally suggested.

@Azdak is spot on here. As you train, your heart enlarges (specifically, the left ventricle), so it pumps more blood with each heartbeat. Your muscles get more capillaries, so they can extract more oxygen from the blood. Your muscles produce more mitochondria, so they can use more oxygen. The upshot is that you get the same amount of oxygen to the muscles with a much lower heartbeat.
In aerobic activities, calories consumed are proportional to the amount of oxygen consumed. That is correlated with heart rate, but the adaptations that I mentioned mean that the correlation is not perfect. My heart rate bicycling at 15 mph is now about 20 beats lower than it was back in 2008, but that doesn't mean that I am burning less energy (other than due to reduced weight). My resting heart rate has also dropped from over 60 to around 46, but that doesn't mean that my energy requirements at rest have also dropped equally, just that the old ticker doesn't need to pump as often to circulate the required amount of blood.0 -
What I've found from this is that I should just keep on doing what I'm doing and I'll still lose calories. I've taken my measurements and I've lost an inch round my waist
So even though I only lost a lb losing an inch is fine by me
and my fitness is improving too.
