"I lost 3 lbs and a percent of body fat in a week" I always wonder when I see this - are other people's weights that stable? I can lose (or gain) 5-10 lb in a week without doing anything different, other than weighing myself at different times of the day, drinking more or less water, various other things.

I'm skinny, and other than the weight of the food I eat / defecate, my weight will not fluctuate at all. I can eat whatever I want, however much I want, and not gain weight. I was able to gain 5 or so pounds, but only after I ate whey everyday and did a lot of lifting. I might be able to gain if I tried some ridiculous whey / protein diet and workout regimen, but I don't care that much. However, for the past 5 years,…

> I can eat whatever I want, however much I want, and not gain weight.

According to my subjective observations, people who claim to have this mystical property are very hyperactive or very good at (involuntarily) skipping meals.

Ok, IIRC the maximum amount of fat you can lose in a week is around 2lb (or 1kg) You can absolutely lose more than that, if you restrict your calories or doesn't reach macronutrient requirements you may lose lean mass. Of course you can clock more than 2lb easily (on a first week): - You lose muscular glycogen because of a caloric deficit - this means you also lose water - If you weighted yourself while 'heavier' bec…

2lb isn't the maximum fat you can lose in a week; it's the maximum fat you can lose safely in a week without engendering muscle loss (at non-obese weights). If you are obese or morbidly obese, you can lose significantly more than 2lb/week safely (indeed, the Biggest Loser is basically just a televised fat camp showing how this works in practice).

Ok, that's what I meant, I wasn't 100% sure you could lose more, thanks for explaining

Of course Not the glicose thing really, walking uses very little energy, it would take a lot of exercise to deplete glicose, not walking slowly but the fact that you can't concentrate while exercise is a huge deal breaker. Not to mention the fact that while you are walking your head keeps bobbing up and down making it harder to read things.

It's not how much energy is burned in your muscles, it's how much energy is burned in your brain. Walking at any speed requires more mental processing than you'd expect, just to make sure you don't trip on your own feet. E.g., here's a study showing that even very slow walking (1.77km/hr) prevents you from typing quickly on a cell phone: http://dl.acm.org/citation.cfm?id=1085798

I'm not questioning the 'exercise makes it harder to do some tasks', as your example shows, this is pretty much a given.

But it's not so much about calories, it's about brain workload, walking requires a mental effort that subtracts from whatever else you're doing at the same time. More glucose won't help.

And if typing is difficult, what to say of activities requiring fine motor control, like drawing. They're almost impossible!

Not to mention the insulin/glucagon system controls blood sugar very precisely, you'll rarely have a lack of glucose in the sugar unless you really exercised a lot

5-10lbs a week is beyond what's considered a normal weight fluctuation. Either your scale is broken or you should see a doctor.

Sorry, but after a little research I don't think you're correct.

Walking desks are inefficient and overkill for the ergonomic concerns of desk work. The practical solution is to have a properly adjusted [1] workstation and get up to walk around for ~5 minutes every hour. On a treadmill, you will lose more than 5 minutes due to inefficiency anyway. And the 5 minute break you take can be used productively (meet with a co-worker, make a phone call). Having a standing desk in addition…

>The key is movement: there is no active blood flow to your spinal disks, they need movement or microtrauma will accumulate. There are also no nerve endings in your discs, so you don't feel anything until there is already serious damage. That's why a walking desk is preferable. I can walk at a slow pace for hours but standing in one place becomes tiresome after 15 minutes.

Constant movement is not necessary, hence the walking around 5 minutes per hour.

I agree standing desks are not for everyone.

Isn't that because you're looking at a screen and can't see where you're going? :p

I would count that as a definite factor (not having read the study), but, I can imagine that even without the screen, people walk slower when typing, as concentrating on the words is distracting a faster walk.

Keep in mind that physical exercise and mental concentration both deplete a common resource pool of glucose in the brain. There are robust, well replicated experiments that show it's significantly harder to perform any mental task while exercising. Daniel Kahneman has a great everyday demonstration of this: While walking with a friend, ask her to multiply two two-digit numbers and see if she slows down. (You can also…

Do you have any information to indicate that this kind of cognitive interference is due to glucose depletion?

I'm curious if there has been any research into walking slowly on a treadmill, though. The upper level of your ability to job is far more demanding physically. And it's also a bit demanding mentally as your body is busy mapping a route, looking out for stones or cracks you might trip on, etc. Walking slowly on a treadmill with your desk in front of you could yield a very different result.
