Personally I would build my own system to run linux on. It isn't as hard as some think it is. There are lots of tutorials on it and odds are there is a nerd some where close by that will help you.
Yeah, but I don't have a 3D printer to make the case out of, and if I make it out of wood in my garage it'll be a bit too heavy, not to mention hard to ool. (I'm sure you understand what form factor an "UltraBook" is.)
To point a finer point on this issue, I think the deficiency in the study has to do with the groups involved.
They may have found two groups who have a common goal (weight loss), but I'm willing to bet that the group who went out of their way to consult with a health counselor have FAR more motivation to achieve the goal of overall health
I think that everyone in the study was consulting with a counsellor, and that's how they got onto the study. I may be wrong, but that's what the study seems to be describing....
It is impossible to lose weight if you eat more than you burn, even if all of those calories are "healthy".
Not necessarily true. For a while, I was on a "grazing" regime, as it had been advised both by a doctor as a method of managing my heartburn (heartburn often being triggered by filling up the stomach, or by eating on an empty stomach) and by a trainer in my local gym as a means of losing weight. The trainer's assertion was that the human body only starts to metabolise food to bodyfat when the stomach is nearly empty. If your stomach isn't empty at all during the day (you need to let it empty at night, though) there's no trigger to the body to save some of the calories for later.
Now I can't say for sure that this is true -- it could be that I only lost weight doing this because I retrained my reaction to hunger -- but I lost a surprising amount of weight surprisingly quickly.
As much as this explanation appears to make sense, like anything in a social study, the results are likely virtually meaningless at the individual level. How any one person reacts to a tracker will not be predictable.
That's an overstatement. What the results cannot do is state categorically that "you won't get fitter with a fitbit". But they're a starting point for an informed decision. When you're engaged in behaviour modification, you have to first be aware of your behaviour, and that includes being aware of tendencies that you may (or may not) have which are likely to affect your behaviour. Knowing something about the psychological effects of wearing a fitness tracker allows you to modify your use of it/attitude towards it and (hopefully) achieve better results.
Sounds like Atkins, which has worked quite well for me.
That's a large leap. The grandparent was talking about cutting out high GI foods, Atkins promotes cutting out all carbohydrate. Ketosis is a pretty extreme state to get yourself in, and there's really no need to worry about low GI carbohydrates. And if exercise is part of your weight-loss regime, you do really need to have a reasonable carbohydrate intake.
