On “GLP-1 pills are coming, and they could revolutionize weight-loss treatment”

…ht lifting plan that actually works for me and I feel good after the day. There are lots of problems with drug reliance still to be worked out, but I'm excited for the chance to rebuild my habits into something good and work my way off to something normal. Related, exercise is awesome but has little impact on long term weight loss! Check this out: link to this video…

On “How long til we're all on Ozempic?”

Just doing more exercise doesn't actually help much with losing weight, as it turns out. The human body will optimize around even intense exercise to reduce calorie burn to a homeostatically stable level. The exercise will still make you healthier (and have some marginal extra calorie burn from e.g. extra muscle mass), but you'll only lose serious weight if you also reduce what you eat. There are a bunch of articles out there about it, but Kurzgesagt has a decent pop-science summary: link to this video

On “Older Americans Are About to Lose a Lot of Weight”

Apparently it's not exercise! 0 Yes exercise is very healthy, that has been proven, but loosing weight is mostly a matter of eating less, at least according to this (reputable) meta source. Apparently, over eating but not getting fat (which holds true for me), leads to other problems (also true for me, I have an autoimmune disorder). Eat less to lose weight. Exercise more to be healthy. (nice, got my first downvotes in less time it takes to watch 1/10th of my source ;)) 0 link to this video

On “The unknowns surrounding the mysterious rise of cancer in young adults”

Recent science suggests that the body adjusts to burn approximately the same amount of calories per day, given a consistent amount of activity, regardless of how much activity there actually is. So, a person with an active lifestyle will burn approximately the average 2,000 calories, but a person at rest will also burn about the same number. I'm oversimplifying massively, but essentially, the theory is that if you don't give your body an outlet to burn with, it will burn the calories on things that aren't good for you. Eg, increasing inflammation. It wouldn't surprise me if some of these effects are contributing factors. Source: link to this video
