    I stand 6 foot and weigh 375 pounds. I am currently trying to use interval training to lose weight. Monday, Tuesday, Thursday and Friday I am on a treadmill alternating my heart rate from approximately 110 beats for 5 minutes and then approximately 145 beats for 5 minutes and then back to 110 beats for 5 minutes. I do this for a total of 30 minutes. On Wednesday I swim for 30 minutes. On the weekends I take off.

    I am not losing weight. I am trying to control my caloric intake. Am I really eating that much that my exercise is fruitless?

    I do not believe that I am building muscle and muscle weighs more than fat.

    All advice will be appreciated.

    Thank you.

    Your exercise isn't fruitless, most people just need to watch the calories in order to lose weight.

    Journal how many calories per day you are eating. Measure your portions. I bet you find some answers there.

    Try our Diet 50-100 lbs club for ideas on cutting the calories and losing the weight.

    Hi BigDogT,

    The exercise is not fruitless. Far from it. First off, it burns calories. Second, it's the single best predictor of maintaining weight. And third, you're getting stronger, more muscle, and more endurance. The more you move the better. As for the weight loss, to lose weight you must consume fewer calories than you burn no matter how much exercise you do. Even if you run a marathon every day you will not lose weight if you consume more calories than you burn. So if you're not losing then you are consuming more calories than you burn, even if you think you're not. In fact, research shows that people can under estimate their calorie intake by as much as 40% to 50%.

    So here's what I suggest:

    1. For the next week write down every single morsel of food you eat, and every ounce of beverage with calories you drink. Estimate the portion sizes as accurately as possible, and weigh and measure everything. Get a food scale and measuring cup to do it accurately.

    2. Then go to one of the following sites to figure out how many calories you are consuming and burning

    3. Then go here to determine your calorie needs.
    Then you can do the math to see how many you need to consume to lose weight.

    4. Then check out one of these WebMD diet clubs for information and support. Group support isn't for everyone, but it sure can be a great help when you need some.

    Once you do these things you will have a better idea how much you are consuming and where to make cuts. Remember, to lose weight you must burn more calories than you consume.

    Take care,

    I was wondering if you could answer a question for me? I was wondering if I walk for 1 1/2 on a treadmill in the morning and walk roughly 4 miles in the evening everyday 7 days a week. Roughly when would I be able to see results? I know not to expect results right away but roughly how long. That is with watching how much and what I eat and drinking water and cutting down my soda intake.

    It would depend on the speed and the incline, your current weight and how many calories you consume.
