Oh good grief. So much misinformation. People really need to stop posting random things they make up or that they "think" are true and stating them as fact.
Walking is good for you. Anything that gets your heart rate raised is good for you. Period the end. That's the answer.
If this was directed at me, sorry
I don't believe I said anything to the contrary, and I thought I made it clear that I was only stating my personal opinion and not fact. Either way, the rest of this post is not me trying to be argumentative, just making sure I'm thinking about things correctly. If I'm wrong, please correct me
Regarding cardio, I never said that it was pointless, just that (what I thought I was saying) was that it shouldn't be the primary method for facilitating weight loss - it should be diet. I do think cardio is important though, just not for weight loss (i.e. creating a calorie defecit).
A convincing artilce I read some time ago (that I unfortunately can't locate right now, but I found through links on this site) basicaly went to explain that when considering the "effective" calories actually burned from a cardio workout, you have to consider that you would have burnt a certain number of calories resting or going about your daily life rather than exercising, as well as considering the calories you won't burn the rest of the day if you rest more after the workout because you're tired instead of walking around doing laundry, dishes, walking the dog, etc, as well as your body possibly being more fatigued and not spontaneously moving as much (fidgiting) the rest of the day, or yes even eating more if you're hungrier from working out (thats actually the point I forgot about initially). So for low intensity exercising like walking, it is my belief (and not necessarily fact) that the effect of the exercise on facilitating weight loss is very little, and much more emphasis should be put on diet. I know people that walk until their feet are ready to fall off and they still don't lose weight.
Higher intensity cardio might create a larger defecit that does create weight loss, however I have read that cardio does not do as much to maintain muscle mass while losing weight. Also, aggressive cardio for weight loss can become a problem when a person reaches their goal and decides they don't need to keep up with the high intensity cardio anymore. Some people go crazy burning 500-1000 calories per day, and when they stop, if the stop is not accompanied by a calorie reduction, the weight can quickly come back. Coupled with the loss of muscle mass, you could possibly set yourself up to completely overshoot your original starting weight quicker than you could even believe was possible. I don't have references for this, only personal experience.
And I don't know I've heard of cardio "raising your metabolism for 24 hours" or anything like that, but I have heard of the effects of HIIT and Weight Lifting continuing post workout, but I don't remember the details so I referred to those around here who know much more than me, like Kara
The other thing I remember is that I have read stories of members here that only focus on diet and weight lifting and lose a ton of fat, without doing any cardio, and I believe it is better to lose "fat" than the generic "weight", which may include things like lean muscle mass. That is empiricle evidence at least that cardio is not all that important for weight loss, which is all I was tryin to say. Not that it wasn't important at all. I also made a point to say I do a ton of cardio, but I'm currently trying to cut back the cardio and incorporate weight lifting back into my routine. I had tons of success in the past losing weight doing nothing but cardio, but I lost muscle mass. I tried doing all weight lifting and no cardio for a few months and while I didn't gain weight and got stronger, I didn't lose any weight either. Then I got sidelined with gallstones and surgery, and am just now getting re-motivated. This time I plan to incorporate cardio AND weight lifting, so when I get to my goal, I can maintain.
These are just things I thought I learned along the way. If I am misinformed or got things twisted or mixed up from what I learned before, I look forward to correcting my thinking. I want to do things right, and I definitely don't want to be giving bad advice.
