Why does my treadmill say I only burned 70 calories?

Question

"They" say you must burn more calories than you eat to lose weight, but I eat more than 70 calories. Is it possible that after a 30 minute running and walking program, I only lost 70 calories? Help??

Answer 1

The systems implimented on tread mills are only a mechanical estimate of your work out. Kinda like saying: "You burned ABOUT/AROUND 70 calories". They are not an exact measure of you calories burned. And the reason for this is because, different bodies burn different amounts of calories. This mean that if we get 3 people with same sex, same height, and same weight and put them on a tread mill for 30 minutes at 10 mph, each one of them will burn a different amount of calories, eventhough the machine may show the same exact amount on all 3.

There's different factors to this: nutrient consumption, calorie diets, metabolism, chemical reaction, body reaction, etc. If you're unsure of the calories you're burning, just keep in mind that, the higher your heart rate is, the more calories your burning. ALso keep in mind that depending on your height and weight, you can consume up to 2500 calories per day and not gain weight. 2000 is normally a good number for an average person (healthy).. However, anything over this figure you might be adding extra ponuds to your body.

So if you consume 2000 but burn out 500 a day (not including your normal activity during the day), that keeps your calorie consupmtion at 1500 calories. This mean you're getting your work outs worth. Keep a good record of your calorie consumption and compare it to your calories burned in your work outs. If its 2000 or below, you're on the right tract.

I think the alternating of walking and sprinting is a good method of (a) burning calories effectively and (b) an effective cardiovascular workout too. Why not try the above at the start of a workout followed by anaerobic exercise (i.e resistance training). This will result in a workout which not only challenges the bodies stamina, but also strength both resulting in a good cardiovascular workout. This could burn more calories than just aerobic exercise alone. Take swimming and rowing for example; athletes in these areas are mostly well built but with no fat on them! So try the walk/sprint for 20 mins, followed by 20 mins of 1 set 10 reps per exercise of say, 8 exercises which involve the most muscle groups. Hope this helps!

Answer 3

Very possible. A 30 minute fast run only burns 140 calories. This is a good lesson for you. It teaches you the caloric value of food, and will help you curb inappropriate eating.

Answer 4

Depressing isn't it? Seeing that some snacks are 300+ calories really should make you think twice. The good thing about exercise is that it will boost your metabolism for hours later and since muscles use the most calories it is benificial to have all of your muscles in good tone. Do some stomach crunches and lift some weights for upper body strength.

Answer 5

Yah ok you should know that you are CONSTANTLY burning calories. Even thinking and sleeping burns calories. If you want to boost your metabolism, lift weights as well.

Answer 6

its a stupid machine...
150lb person
If you sit quietly for 30 minutes you will burn 47 calories
If you jog at 5.5 mph for 30 minutes you will burn 370 calories

Answer 7

that sounds strange to me.....I usually burn near 200 in 30 minutes

Answer 8

YOu can't really trust those. They are often flawed.

Answer 9

Yup, that's possible.
