to ask if anyone can calculate how many pounds lighter I'll be in a year if....

[PatsyFlowers]

I walk for an extra 30 minutes each day.

Power walking.... Fast? Or school run kind of walking?

How fast and how much do you weigh

Around 36lb assuming you are not over eating in anyway

That is at an average speed middle weight

Depends how much you weigh now?

Will you stop to buy a chocolate bar on the way? That's why I gave up exercise. Too expensive.

Assuming average speed that's around 100 calories and frankly you don't get much for 100 calories! Some fruit and plain yoghurt, a small finger of chocolate, a couple of biscuits....... So it will help you loose weight and get healthy but on its own unlikely to result in massive change. Plus you'd need to make sure you didn't up the treats to reward yourself afterwards.

Mind you once you can do that with ease, you may find you go up to 45mins, then start c25k, and one day you'll wake up and find yourself doing Shred, at least that's what happened to me!

How much do you want to lose ? Running is fab to help you shrink pounds and shred for inches!

It's about 100 kcals, depending on your current weight (MFP says about 100 kcal for 30 mins walking 2.5 miles / hour if you're about 10st). That's 36500 kcal per year. 1lb apparently equals 3500 kcals so if you ate the same as you do now, you would lose 10lb. This maths is flawed because it depends on your current weight and speed of walking (and obviously what you eat and how your body metabolises that). Additionally if you lose weight, you'd burn less calories by walking.

Doesn't work like that.

Chances are you'll eat extra calories to make up the deficit unless you are very mindful about not doing so.

Exercise alone has many benefits but if weight loss is your primary goal, just increasing exercise probably won't cut it

I got a dog and walked 2 miles/40 mins everyday. I didnt lose a lb :( I think your body become accustomed to your new exercise so that its just normal. Iyswim

I burn 150 calories walking for half an hour, I do around 3.5-4mph. No idea what that works out to per year in weight loss. I don't eat back the calories.

Got a dog walked 30mins twice daily in the week, at least 2 hours each day at the weekend, continued sensible eating and l lost three stone in a year. However, I worked on brisk walking and I now walk at just short of 6 miles per hour.

Even at 114kg, carrying a 15lb load, I only burn 199 calories in half an hour. Fortunately my baby is double that weight and I will be doing the walk twice a day!

Making a loss of around 500kcal a day, which is equivulant to a small meal.

Try caloriesperhour.com. It's great and can do all sorts of calculations like that for you. Helped me lose 3 stone over the past two years

I weigh 10st now. Just thinking of school run walking.
