What kind of sensor do you have ? I am not diabetic but I'd like to monitor my sugar level somehow.

I think they all need to break your skin in order to test. I'm not aware of any continuous monitors that don't need some blood to work. I anyone is I would be interested.

Here's one https://provider.dexcom.com/education-research/cgm-education...

Also an interesting article about people hacking together their own artificial pancreas https://medium.com/neodotlife/dana-lewis-open-aps-hack-artif...

The most popular ones are the Dexcom sensors and then the Freestyle Libre. Unfortunately you need a prescription for both in the US. Otherwise, if you'd like to monitor your blood sugar, you'll have to do it via a blood glucose meter and just space out your testing. You can buy those over the counter at any pharmacy/superstore and they're relatively cheap.

If you end up buying a blood glucose meter, the best way to get a good idea of your blood sugar movement in your body (if there is any) would be testing at several times throughout the day after specific events (like eating and/or exercising). Waking up (for fasting glucose), pre-meal (to get a baseline), post-meal several times (15 minutes, 1 hour, 3 hours). I would also experiment with how it reacts to different types of food and beverages. For example, try drinking a glass of orange juice and testing 5-15 minutes after. Some non-diabetics still experience very small blood sugar spikes from liquid carb sources.

On one hand, my body is probably fucked from laying in bed for 18 hours a day, every single day, a year. On the other hand, moving about is exhausting and hurts so why would I want to do it? I fully plan on killing myself before 30 so it's not like I'll see the knock-on effects.

Why are you lying in bed for 18 hours a day? Is it depression or another illness? Don't kill yourself just for turning 30, I am 30 and life keeps on keeping on, just as decently as before. Sure my hair line is a bit receded and I get a bit more aches and pains, but by and large it's the same as before, except I have a stability and future set up that I had only dreamed of at 23.

I'm definitely way more attractive to women now than I was at 23 (ten years of trial and error)

Does anybody understand why some of the numbers are so out of proportion with the length of time spent in the study? They say they lost 0.2-0.3kg of muscle mass in the lower half of the body. But that's a very large change; when you exercise and train properly, the maximum amount of muscle you get is like 0.5kg/month (the study's reduction in activity was two weeks long), and when you gain weight some fraction is always muscle (they didn't gain weight but they gained fat mass and lost muscle mass, IIUC from Table 2).

I remember reading that when you start/stop exercising, your muscles retain a different amount of water depending on how much work they typically do. So is what they got an actual change in body composition?

When they report lowered VO2max of 2.2ml/min/kg, that's ±4.7 according to Table 2. Isn't 2.2ml/min/kg an improbably large change for two weeks, compared to how quickly your VO2max will improve if you, e.g., start running? And why is the SD on that so large?

I don't know your situation, but if you need someone to talk to, I'm here my dude.

Why would I want to talk to somebody?

Because you'll find that when you have to explain what's causing your problems that it's not nearly as bad as it seems when it's just nebulous garbage rolling around in your head. Also, if you talk to the right person, you might discover that you don't exist and that Life is a dream, and that the point of it is to become infinitely loving and utterly selfless ...

Why kill yourself before thirty?

I don't want to be old.

30 isn't old. I'm 38, and I'm more active and exploring life than ever. "Old" is only what you are when you stop pushing yourself.

31 and skating almost everyday, strongest, most handsome & probably most youthful I've ever been since beginning adolescence. Do Recommend.

"Public health recommendations promoting physical activity should incorporate advice to avoid periods of sedentary behaviour." How do we interpret and apply information like this? Many people work in front a computer these days so it can't actually be applied to them (read us).

> How do we interpret and apply information like this?

Sedentary desk jobs should be considered work hazards and employees should be given desks that can easily be changed to a standing desk and also be allotted a walking break every 15-30min, or install rows of treadmills with an ergonomic laptop holder.

I work in front of a computer, at a standing desk. You can get adjustable desks too and stand for part of the day. The "not sitting" part is achievable, I believe there are countries (Denmark maybe?) that even mandate that computer desks in offices be adjustable so everyone can choose whether to sit or stand. That said, I've been working at my standing desk for over a year, I wasn't very fit before, and I don't feel…

Standing desks have their problems too (veins, etc). Seems that treadmill desks or literally taking a walk are much preferable

I used a walking desk for a couple of days a few years ago. It was fine for stuff like reading and responding to emails, but I couldn't write even simple programs while walking.
