When you're doing the elliptical, treadmill, bike machine at what point does a person start to burn fat?

Question

I've noticed that I start sweating 15 minutes after being on the elliptical machine. Is this when fat burn starts?

Answer 1

You are burning fat the whole time. Whenever you use energy, you are burning fat. You just have to use more energy then your food is giving you, and you will lose fat.

Answer 2

There are really 2 issues here, one is STARTING to burn fat and one is losing fat.

Coming into play is your maximum heart rate and your current weight. Your maximum heart rate is found by subtracting your age from 220. I'm 45, so my maximum heart rate is 175.

Now, you should maintain 80% of your maximum heart rate (for me it would be 140) for at least 10% of your weight if you are over 200 pounds, or at least 15% of your weight if you are under 200 pounds. If you were 250 pounds you should maintain this for at least 25 minutes for most effect.

Sweating is also a good (but not the best) indicator. You should sweat hard for at least 15 minutes. As you become more fit it will get harder to break a sweat.

Now, keep in mind that as you become more fit, you may begin to lose inches but actually gain a little weight. This is because muscle is half the volume and twice the weight of fat.

Think of this... 90% lean hamburger is 10% fat by weight but 20% fat by volume, 80% lean hamburger is 20% fat by weight but 40% fat by volume, 50% lean hamburger is 50% fat by weight but 66% fat by volume!

Answer 3

Fat burn occurs after having your heart rate elevated for an extended period of time. Generally it is for more than 20 mins. Sweat is generally a good indicator that you are reaching the right level, but a heart rate monitor would be the best way to measure your body's response to either and let you know when fat burn occurs.

Answer 4

Noone really knows when. It's different for everyone. The speed at which you are burning calories is sped up or slowed down depending on how you train your metabolism to function. If you exercise regularly, you will speed up your metabolism. This means that you can burn fat or calories even while you are sleeping after a day of moderate activity. You train your body to keep itself in better shape.

Answer 5

The calorie counter isn't off. in case you're in basic terms going 2 miles in 30 min you distance meeter is off. the final walking speed is approximately 6 miles an hour so in case you're in basic terms doing 2 in 30 min you're going slower than walking speed. To awns er your question a tared mill will burn extra energy than a elliptical simply by fact it demands using extra muscle groups on your physique. besides the indisputable fact that simply by fact of much less resistance on an elliptical you will desire to be waiting to circulate longer. Its additionally extra acceptable on your knee's and lower back.

Answer 6

To really get the best benefits, you have to stay on it for atleast 30 minutes, but i stay on for about an hour. Keep your impact low, because the slower and more controlled the movements are, the better the results. The reason is because you are not using momentum, you are using your muscles. If your sweating your are probably working it to hard to be considered low impact. You are probably getting a better cardio workout and than fat burning.

Answer 7

You are burning fat every moment of your life that your caloric
intake is less than your caloric output....
You do not "start to burn fat" at any particular point on a treadmill
other than the moment you step onto it...
Your caloric output increases the moment you start exercising..

Answer 8

with what i know, and thats not much, lol, you start burning calories as soon as your heart rate starts going up from your resting heart rate, then once you get your heart rate to the high, but safe level, you will burn more, and the longer you keep it there, the more you will burn

hope this helps

Answer 9

I've heard 20 minutes which why 30 minutes minimum is recommended. Of course it depends on your current weight and how fast you are going.
