Perhaps it should be better worded as 'With only one exception, everyone I know who is in the "eat a lot and stay skinny" category dress up no differently than normal people do.'

On the topic of staying cool while doing physically demanding work outdoors, one unsuccessful attempt was by Rinoa Super-Genius who tried to use a Peltier to cool her down. The most obvious flaw is that the Peltier uses a lot of power which does not go well with portable devices, but the problem that made it unusable was that it attempted to pull out the heat over a small area, which is not very effective.


My idea with the fan would use far less power and theoretically can work at least as well as the "low tech" solution that shows off too much in many environments.

Actually these posts make me somewhat sad as well. In the last half year I've been exercising with a physiotherapist to improve stability in my knees, muscle strength in my upper legs, and eventually reduce medial knee pain. I liked the physical exercise, as it is nice to clear you head after a long day or stressful times, but unfortunately physically there were only adverse effects for me. That is not to say it came as a big surprise, given my history with orthopedic surgeons.

Unfortunately it does mean that I'm quite limited in my exercise options. For example, last few months I picked up basic cycling again, and it had a significant negative effect. I'm actually looking for alternative sports/workouts that don't put stress or repetitive movements on the knees. People have been recommending swimming to me, but my physiotherapist has recommended against it due to the instability (AFAIK applies to the breaststroke in particular). But maybe I should try it out if there are no alternatives..

I'm sad to read that. I started training seriously a few years ago, trying to rehabilitate an injured knee. My doctor said it would take eight weeks. It took two years.

For six months I could barely walk. For another three months, I couldn't jog, not even a few metres. For another year or more, my knee would occasionally malfunction while running. The kneecap wouldn't track correctly, and almost jam, but then a few steps later would be fine. This glitch was exasperating, unnerving, and disheartening.

But as luck would have it, even when I couldn't jog, I was problem-free on a stationary bike and an elliptical trainer. So I'd walk to the gym, and use them. I gave up leg strengthening exercises, because they seemed to make my knee worse.

I started to lose confidence in my physiotherapist. Reading the medical literature, I worked out that my recovery was being held back by lingering Arthrogenic Muscle Inhibition (AMI). My physiotherapist seemed clueless about it, gym trainers didn't seem to know about it (not their specialty, so not their fault). My doctor's prognosis was way off (not his specialty, so not his fault)). It dawned on me that, despite well-meaning professionals doing their best, I had to solve this myself. Two years.

And the same with nutrition, and training technique. Because it hit me, hard, that if I don't learn the how, what, and why, I'm at the mercy of well-meaning people who may simply be getting it wrong.

I started off as fat as a department store Santa with arms like sticks, at 93 kg. Not through obvious overeating, just through inactivity and eating a "well-balanced" "conventional" diet recommended by the usual "Intellectuals Yet Idiots" that infest mainstream nutrition.

My weight dropped to 73 kg over two years. Now it's 78 kg, but I'm leaner. I'm stronger now and lifting more weight than ever. The once-injured knee is symptom-free. My aerobic capacity is good but not outstanding. In my competitive cross-country running days, my resting bpm got as low as 39. Now it's 50 bpm, so I'm well short of my genetic potential. There is room for improvement, if I decide to pursue it.

As I phased leg strength training back in, especially single-leg training like King deadlifts, I realized that it helped my running - more power on hills, more comfort when holding a fast pace just below a sprint, better running form when fatigued, so less joint strain. If you are an endurance athlete, I recommend (FWIW) power and strength training. It helps. You are more functional with it, and less prone to injury. The fact that hybrid training (training for strength, plus power, plus endurance) is still a controversy is just astonishing. Facepalm-worthy, really.

To the OP: don't lose hope. Keep searching for something you can do, and enjoy. Maybe it's some form of swimming. Maybe some form of rowing - on machines or on water (I once knew a guy who used to kayak to work). Maybe something unusual you haven't tried. Keep looking.

Maybe take a look at isometrics, you load but with little to no movement. Used to do them when stuck in the car between classes.

AFAIK it does not.
Ten years ago I swam with a group of older friends, I was in my begin 40 and they were 55-65.
I was always amazed they had this bellies while they were not really eating that much.
Now if I look in the mirror I see the resemblance  :(
Probably, I am not expert, your metabolism slows down with age, so you need less and less calories but your stomach is still the same size, your brains are not reprogrammed over the years and so the older you get the more extra calories you eat although you might eat less than in the past.
Nature is cruel. Although nature would probably argue that the human body design was not made to last more than 30-40 years (average lifespan few thousand years ago) , so you can also look it at the positive side, these are the bonus years  :)

True, I wonder where and when then, because I am a desk jockey, perhaps the brain consumes more but that does not help me burn fat on my belly.
I do walk to the coffeemachine more often than at home  ;D

Actually the ratio between waist and height is also quite rough, better than BMI, but still not perfect. The waist to hip ratio is a better measurement. Mine is a healthy 0.85. I used to be over 1, before I started cycling.
