Another reason, newbies, why you should forget the friggin' "rocket
science" and just stick to the basics! http://www.cnn.com/2007/HEALTH/diet....exercise.reut/ index.html Too many newbies are concerned over minutiae which probably only benefits elite athletes...just get out there and shake it vigorously, baby! Forget about how many reps of how many sets, whether your elbows should be flared or tucked in, or how many grams of this and that and when...relax, listen to your own body (as opposed to your ego's wishes to be lazy or be Arnold)...just do it, but make sure to enjoy it! Dieting and exercise both equally good at taking off pounds...dieting alone does not appear to take off muscle along with fat...muscle mass does not boost metabolism.... Nope, you still can't "spot reduce," hehe, and you should still exercise -- but stop sweating the small stuff like which supplements, whether you need more protein, when to take what, how many of what to lift, how to lift this or that, whether you should do aerobics, blah blah blah.... |

Agreed. http://www.brinkzone.com/articledeta...catid=3&aid=95 Dieting and exercise both equally good at taking off pounds..dieting alone does not appear to take off muscle along with fat. Study does not say that either. The study found both about equal in terms of loss of FFM, not that dieting does not = a loss of FFM. From the study: "In our study, fat-free mass was reduced with the 6 month intervention and was not different between the intervention groups. Our data suggest that fat-free mass is reduced in parallel with the degree of caloric restriction and that regular aerobic exercise (5 days per week), at least in non-obese individuals, does not preserve lean mass." ..muscle mass does not boost metabolism.... The study didn't even test for that, so how one could conclude that from that study is a mystery. Funny thing is, all that study actually did was confirm what we know and other studies find: aerobics and low protein diets suck for preserving FFM. Can choice of exercise and or macro nutrient ratios have an effect? Yes, they can: http://jn.nutrition.org/cgi/content/full/135/8/1903 |

The study didn't even test for that, so how one could conclude that from that study is a mystery. I don't think they addressed that issue, but the "muscle mass vs. metabolism" issue has been studied previously. According to this often-cited study, (http://www.obesityresearch.org/cgi/content/full/9/5/331 or http://tinyurl.com/23fm33 ) Resting Energy Expenditu Systematic Organization and Critique of Prediction Methods (ZiMian Wang, Stanley Heshka, Kuan Zhang, Carol N. Boozer and Steven B. Heymsfield), published in Obesity Research (http://www.obesityresearch.org) in 2001: "The resting metabolic rate of skeletal muscle is 13 kcal/kg per day (5.9 kc al/lb per day)." "The resting metabolic rate of adipose (fat) tissue is 4.5 kcal/kg per day (2.0 kcal/lb per day)." So, if you do a bunch of resistance training and manage to replace 5 lbs of fat with 5 lbs of muscle, your Resting Energy Expenditure will increase by a meager 19.5 kcal per day...that's less than a 1% increase in metabolic rate for the average male. By way of comparison, if you: Walk briskly for 20 minutes, you'll burn about 100 kcal. Lift weights vigorously for 30 minutes you'll burn about 200 kcal. Run 5 miles, you'll burn nearly 600 kcal. Ride a bike briskly for 20 miles, you'll burn nearly 800 kcal. Bottom line - lifting weights has many benefits, but "increased metabolism" is not one of them.

"JMW" wrote in message news Since the primary issue under this subject header is FAT metabolism, I would say that "increased metabolism" is very definitely a benefit of resistance training. My take on the "new" report is that it simply confirms the calorie in ... calorie out relationship as it applies to weight loss. For the average, overweight dieter it is more realistic to cut daily calorie intake by, say 500 to 1000 kcal per day than it is to burn an extra 500 to 1000 kcal per day through exercise. But either way ... it's the calorie deficit that matters. As for metabolism changes due to exercise .... I don't know. Based on my personal experience of the past 3+ months of dieting, daily cardiovascular exercise and heavy (for me) weight lifting routines every other day that has resulted in a 50 pound weight loss so far, I would guess my overall metabolism has slowed. I base that assumption on the following: My calorie intake requirement to "maintain" current weight has dropped from over 4000 per day (at 260 lbs) to about 2500 per day (at 211 lbs) according to the various BMI charts found on the web. I've recently experimented by consuming over 2000 kcal a day for a week or so while still maintaining the same exercise program and the weight loss has all but stopped. The other indicator (I guess) that my metabolic rate has slowed is that my resting heart rate has dropped from around 80 BPM to around 65 BPM, again comparing the numbers at 260 lbs and 211 lbs respectively. As to muscle mass ... I think it's too early to tell. I've definitely added some mass ... my arms are a bit thicker with a little more muscle definition, but I am far from being a Charles Atlas.

So, over the 72 hours post weight training, what is the increased fat metabolism? Presuming you haven't eaten more to compensate for the increased exercise. jack |

RMR increased significantly (p0.05) pre to post in R+D. It was also significantly greater (p0.05) in the R+D than in the C+D group after 12 weeks. No change was observed in the C+D group pre to post.

Whatever it is, it simply works. http://www.jacn.org/cgi/content/full/18/2/115/T2 Results of comparison of three times per week full body resistance training to four times per week of 1 hour cardio, while on an 800 kcal diet. People training with weights preserved lean body mass and achieved better results as expressed by fat % changes. They also increased their VO2max similarly to aerobic group. Resting Metabolic Rate, as quoted above, went up in resistance group and went significantly down in aerobics group. Muscles will burn calories at rest, but only if you train them! -- Andrzej Rosa |

I've recently experimented by consuming over 2000 kcal a day for a week or so while still maintaining the same exercise program and the weight loss has all but stopped. Try doing full body workouts on your weight days. It should help you by stimulating higher muscle mass overall, which then has to recover between workouts. Limit the rest intervals too, if you are serious. Additional muscle mass speeds up metabolism only if it was stimulated by weight training. If you didn't build any additional muscle mass (which is quite possible, taking in account that you lost so much weight) you shouldn't expect any increase in you BMR. Still, you can squeeze some increase from existing muscles by doing full body workouts. The other indicator (I guess) that my metabolic rate has slowed is that my resting heart rate has dropped from around 80 BPM to around 65 BPM, again comparing the numbers at 260 lbs and 211 lbs respectively. I wouldn't worry about that. You are getting in shape. As to muscle mass ... I think it's too early to tell. I've definitely added some mass ... my arms are a bit thicker with a little more muscle definition, but I am far from being a Charles Atlas. You can consider a maintenance phase. It should allow you to build some extra muscles, which will show better once you cut down to your target bodyfat percent. -- Andrzej Rosa |
