What a lot of people don't realize is that obese people are VERY muscular. It takes a ton of muscle and bone density to support that much extra weight. This is why exercise is important in any weight loss regimen. It isn't important because it burns calories, but because it maintains the condition of your body.
- squirrel6 3y agoIndeed. The fact that they (the drug’s sponsors) didn’t look at how much of the weight lost during the RCT was lean mass is very damning. To your point, we know lifting weights specifically is crucial for maintaining bone mineral density[1]. I wonder if there’s a correlation between loss of lean mass and reduced bone mineral density. [1] Crucial being a relative term with respect to the applicability of this study’s findings https://pubmed.ncbi.nlm.nih.gov/31797417/ https://pubmed.ncbi.nlm.nih.gov/31797417/ Edit: for sourcing.
- jackmott42 3y agoEvidence is mixed on weight lifting and bone density. Some studies see no benefit at all. The idea that it is "crucial" isn't supported by any evidence at all. Most people have bone density that is fine without any weight lifting. On the other hand the evidence on running and bone density is very consistent.
- klipt 3y agoSo for good bone density you need to pursue a high impact sport that might destroy your joints? Unfortunate if true!
- scp3125 3y agoTry taking a look at high intensity resistance training. It's the weight lifting equivalent to high intensity interval training. It's very effective, and it's low impact relative to the amount of time spent exercising.
- foxyv 3y agoThere is a lot of evidence that high impact sports like running actually improve joint health. Especially if they practice appropriate resting and nutrition. I suspect that a lot of the injuries we associate with high impact activities are from people who have lost conditioning from inactivity, attempting to resume exercise without knowing their new limits. https://www.nm.org/healthbeat/healthy-tips/fitness/is-running-bad-for-your-knees https://www.nm.org/healthbeat/healthy-tips/fitness/is-runnin...
- red-iron-pine 3y agosame idea as building a callous on your hands or feet. lots of use tends to toughen your joints.
- scp3125 3y agoYou are incorrect. There is a consensus among scientists who study this subject that /skeletal/ muscle mass is directly associated with bone density. There are specific arguments and disagreements about what exercise is most beneficial for increasing overall skeletal muscle mass index efficiently, but the relationship between skeletal muscle mass, blood flow and nutrient distributions, the downstream effects on hormone regulation systems, and how all of those improve bone density are very well studied.

- fatfingerd 3y agoAFAIK resistance training would beat aerobic sport (for this problem); the correlation is right in the headline. https://pubmed.ncbi.nlm.nih.gov/31797417/ https://pubmed.ncbi.nlm.nih.gov/31797417/
- foxyv 3y agoWhile I'm not sure about the connection between weight lifting and bone density, I do know that inactivity is a major cause of injury and lost physical fitness. A person who is obese is getting that exercise just by existing. Every time they stand up, lift an arm, bend over, or walk across the room, they are engaging in more exercise than a low body weight person does in the gym. Once that weight is gone, they will need to increase activity levels.
- oarfish 3y agoI would be surprised if the activity of moving you overweight body around could be classified as resistance exercise when it comes to any of the positive adaptation usually elicited by lifting bb
- foxyv 3y agoI imagine if you lifted bar bells 24/7 it would be way less healthy. I know that wearable weights are not recommended because it can cause health problems and injuries. I like this video by Phil Gaimon. Stuff like walking, standing, balancing and getting on his bike are much more difficult. https://www.youtube.com/watch?v=Y6W2Hmy0Lzo https://www.youtube.com/watch?v=Y6W2Hmy0Lzo
- jackmott42 3y agoI don't understand why your first claim supports the second. I agree obese people are very muscular. But since you won't need so much muscle and bone when you weigh less, why is it important to exercise any more than it is generally?

- foxyv 3y agoAs you lose weight, you need to adapt to your changing body. You will lose a lot of muscle in the process which is okay! However, all that exercise you got from just standing and walking normally will go away too. Maintaining condition will require intentional effort, otherwise you will start to see injuries. Think of it like physical therapy while recovering from an illness.
- renewedrebecca 3y agoThere have been some studies that show that muscle loss is disapportionally higher than fat loss, which would lead to worse body composition after losing weight.
- Buttons840 3y agoThis would surprise me since the primary reason a body stores excess fat is to be used for energy when needed. Then, the moment of need arrives and the body burns mostly muscle? Citation would be appreciated.
- foxyv 3y agoI always think of it as the difference between starving in a cave waiting for winter to end and starving while attempting to hunt down food in the summer. In the winter, reducing energy expenditure is important so you lose muscle first. In the summer it's more important to maintain condition so you can fight off competition and cultivate food sources. By hunkering down on the couch and just losing weight you get the winter scenario. By exercising while you lose weight you get the summer scenario.
