New study may show why exercise is useless for weight loss

Exercise is almost useless for weight loss. Just about every serious expert know that trying to make people exercise more, in scientific studies, has an almost negligible impact on their weight.

A new study shows a possible reason. People who are very physically active do not necessarily burn more calories than people who are moderately active. The body seems to adapt, possibly by resting more after exercising.

It may be one of the main reasons why exercise is not useful for weight loss. Exercise is good for health, strength, well-being, many things. But when it comes to weight loss, it’s almost all about what you eat.

Exercise can be a bonus while losing weight, but you’ll have to do it in a smart way:

    I totally agree with this atricle, I work out regularly and only see real result when I dial in on my diet.

    I agree. I have toned up more just on the LCHF diet than iv ever done on any other diet with exercise and I havent even STARTED to workout yet since starting the LCHF diet. Ive lost 9lbs in 3 weeks and look like iv lost a hell of a lot more! A life saver, this diet is!

    I'm going to be contrary - I don't agree. Or, to be more precise, it depends on what the meaning of the word "exercise" is.

    When I was on the Atkins diet back in the 90s, I was doing brisk walking with friends for about 45 minutes every day on our lunch break. When I tweaked an ankle and had to skip walking for a week, it barely made a dent in my weight loss.

    On the other hand, when I did Body for Life back in 2012, I was also doing 30-45 minutes of exercise per day - but it was 30 minute HIIT sessions alternating days with 45 minute weight training circuits. When I tweaked a knee and shoulder and had to stop the workouts, my weight loss - up to that point comparable to what I've seen on LCHF - completely stopped and even reversed slightly, despite my dialing back food intake to compensate.

    Based on those and other experiences, it seems pretty clear to me that just talking about "exercise" - as if running on a treadmill equals brisk walking equals weight training equals HIIT equals Zumba equals ... (you get the idea) - is meaningless. Just as different ways of eating have different effects on the body, different ways of exercising also have different effects.

    I'm curious what the effects of combining interval/circuit type training with LCHF would be. Planning to start a 12-week trial of that in the next week or two.

    Hi Mike,

    Did you start the trial? I'm very curious to the results of exercise and LCHF lifestyle.

    Losing weight is not all about getting in shape it also help you to gain physical strength. I do exercise daily as part of my healthy lifestyle. I read that exercising alone wont cause weight loss since I have been exercising alone at home. I do some research and visited consumerhealhtdigest site it provides me useful information about exercising alone. For me, its not a bad thing, I have learned from consumerhealthdigest as long as it makes you comfortable it will work.

    It's pretty simple mathematics. Depending on your size, your body needs about 2,000 calories a day (14,000 a week) just to live.
    If you want to lose weight, you subtract 3,500 a week from your diet and you will lose 1 lbs.
    Whether that's eating fewer calories or burning more through the week, you will lose weight.
    I find that a healthy combination of the 2 is your best option.
