Exercise is wasting our time???

loving everything I'm reading. That's exactly what I was hoping for when I posted this topic. Thank you everyone for all the great feedback!

So you can just lose weight from calorie deficit alone, but physically, you probably won't be any better off if you don't include exercise to assist.

Pick your poison. I choose to exercise.

Exactly! At the very worst, exercise is only improving your health and your life, and not making it any harder to lose weight. Plus, it gets me out of the house away from where the food is.

In my opinion, in the context of weight loss, the primary purpose of exercise is to ensure preservation of lean body mass. 2-3 days/week of "heavy" resistance training will do this. Cardio can provide a larger caloric deficit, but it is infinitely easier and more time-effective to just do so via diet. Also, recovery capacity is limited when at a caloric deficit, particularly when engaging in activity that forces the body to burn fat rather than muscle (resistance training), and for a person already in poor shape, adding cardio is a recipe for overtraining.

The issue with losing weight via diet alone is that you will lose muscle as well, and for people who are very overweight, leptin/insulin resistance means that a good portion of that weight loss will be muscle. If you weigh 250 pounds and you lose 25 pounds of fat and 25 pounds of muscle, you will, I guarantee, end up looking and feeling even worse than you did when you started your diet. With resistance training and proper protein intake, loss of lean body mass can be kept to virtually nothing until 'healthy' levels of body fat are achieved. In the same scenario, a 250 pound person who lost 25 pounds of fat would be both aesthetically and from an overall health standpoint better off than a 250 pounds person who lost 25 pounds of fat and 25 pounds of muscle, despite still being 25 pounds heavier (that was probably a bit confusing, but whatever).

I am sure that the study was correct in that when people add exercise, but do not control caloric intake, they will naturally increase caloric intake to compensate for calories burned while exercising. This can easily be overcome by tracking your calories.

Exercise makes me feel good and when I feel good it makes my mind in a better place. And that makes me eat less. So for me it's a round robin!

I exercise because it makes me feel good.

And it also makes you healthier. Isn't that enough?

BTW if it lowered metabolism, then people eating back exercise calories wouldn't lose any weight. I could see how excessive cardio could cause lots of stress and mess up weight loss, but that's not the same thing.

The high after a good workout is great. Also, for me, it's a great stress relief.

^THIS!

That's too funny. That we should be so surprised about this.

"Very simply, it appears that exercise lowers metabolism, and it does so to such a degree that it almost exactly compensates for calories burned during exercise. In other words, if you burn 400 calories doing an exercise, your metabolism slows so that you burn 400 calories less."

Exercise is Great For a Lot of Things... but Weight Loss... Not So Much
http://www.hollandclinic.com/About-the-Medical-Weight-Loss-Program-at-Holland-Clinic/exercise-weight-loss/exercise-may-not-improve-weight-loss

In the NY Times by Gretchen Reynolds, a heath and fitness writer.

"As a result, although they were burning up to 500 calories during an exercise session, their total daily caloric burn was lower than it would have been had their metabolism remained unchanged, and they lost less weight than had been expected."

Dieting vs. Exercise for Weight Loss
http://well.blogs.nytimes.com/2012/08/01/dieting-vs-exercise-for-weight-loss/

The same Gretchen Reynolds mentions a University of Copenhagen study.

"But there is encouraging news about physical activity and weight loss in a new study by researchers at the University of Copenhagen. It found that exercise does seem to contribute to waist-tightening, provided that the amount of exercise is neither too little nor, more strikingly, too much."

For Weight Loss, Less Exercise May Be More

And here's what Robert Lustig, author of Fat Chance, says in an interview.

"There is nothing bad about exercise. It’s all good. It’s just that it doesn’t cause weight loss on its own and that’s where the science comes in. There are no studies, zero, none in the world literature proving that exercise will cause weight loss on its own. Time Magazine came out with a cover story on this a couple of years ago and so it’s not that controversial."

Why Exercise Won't Make You Thin
http://www.time.com/time/printout/0,8816,1914974,00.html

Some mentioned muscle vs fat. This by Christian Finn, MD in exercise science.

"If you were to lose two pounds of fat and replace it with two pounds of muscle, your resting metabolic rate will increase by less than 10 calories per day. It would take a vast amount of muscle to substantially increase your metabolic rate — far more than most people are going to build in the gym."

The Myth about Muscle and Metabolism

When all is said and done, I go for neither too little nor too much.

Losing weight is a result of calorie deficit. I exercise because it allows me to eat more.

Me too!
Honestly, I think it's pretty simple. Cardio is good for your heart/lungs. You don't need tons of it. I mean, you don't need to train for a marathon or anything.
The best way to burn lots of calories is to increase your metabolism, not to walk or run or jump around for 30 minutes. Boosting your metabolism overall is going to burn calories all day long. The best way to increase your metabolism is to build muscle. That's will help you burn more calories and maintain what you've accomplished. And eat more food.
So, focus on getting more muscle on your body. Do some cardio, for health reasons and to make you feel good, but don't do 20 hours a week or something cray-cray like that!
That's my opinion. Don't worry too much about every little annoying study.

well exercising (lifting/cardio/HIIT) and eating in deficit helped me go from 20+% body fat to 12-13% body fat..but what the hell do I know..

This sounds like something The Onion would write.

:laugh: :flowerforyou: I love The Onion

Biggest waste of time is thinking about whether or not one wants to try to exercise, eat right and get fitter and healthier. Just ****ing do it.

Ididn't read this entire thread, just parts. I would like to see this "study". Is there a link to the actual paper, or a title given?

The problem is when people (reporters) interpret an article and post a '"news story" about it. The OP may have read someone's interpretation rather than the original study; I don't know.

Too much cardio can definitely alter one's metabolism in a negative way. But to say that "exercise" does that without defining what one is talking about is a blanket statement that means little.

What can I say, I'm scientifically-trained, and my BS radar goes up when I read something like that.

ndj1979

starting to suspect this is a troll thread..

but I will add this final though ..

If exercise makes your metabolism lower, then how is it on exercise days I burn 3000 to 3200 calories but non exercise days I only burn about 2000 to 2400????

There is a possible long-term effect from overdone cardio. Our body has intricate metabolic feedback mechanisms, and tends to adapt to high steady-state stress by decreasing metabolism to conserve energy--to survive, literally. But you'd have to really overtrain for a long time for it to impact you. Especially cardio. The body would basically shut down from overuse. That's why too much cardio can cause adrenal exhaustion, bone weakness, vitamin deficiency, etc. But most people never overtrain for long enough to cause such things.

I think someone has blown this idea way out of proportion, personally.
