Well, duh! The latest issue of AJM publishes a study of the non-correlation between wearing a fitness tracker and shedding adipose tissue. All the tracker does is tell you how much exercise you’re getting. It doesn’t provide any info about how much you need to be getting to reach whatever goal you have. Wearing a tracker is a lot like being at a gym: you actually have to DO SOMETHING with the resource, or you’re wasting your time and money.
It is kind of like reducing portions to lose weight.
You can reduce the portions, but if you're still eating small portions of calorie-dense junk or etc. along with complete meals and other empty calories in between, you're bound to gain body fat.
Calories (among other things), in this case, matter much more than portion size.
The way I grew to understood losing fat was that it isn't about portions or entirely about types of food (but they do influence it) -- it is largely about calories overall, which many people have no clue how many they get to start with (but other things matter too -- just don't want to make this post too long). Some people who don't gain weight may attribute it to their metabolism and vice-versa -- but with so many people not even really eating consciously/looking at what they eat or measuring calories in any form, it's easy to see how these ideas can be off. A person can think they have a fast or good metabolism, which is why they are so skinny (but they might only be getting ~1,500 calories a day or less).
Some may track their exercise, but they might undo all of that hard work by splurging or scarfing down too many empty calories still too often/eating not so good foods, which may impede metabolism/hormones/etc. somewhat and creates a vicious cycle of overexercising and not seeing as good progress, if any.
My problem is I like to drink beer and straight booze when I'm not working. I eat of course, but I don't get the feeling I gorge on food. I try to eat only half of many things I buy that look like they are meant to be eaten as one meal. But I have my little tummy that most people don't think is too bad which is because so many people just let themselves go, I don't look all that fat by comparison.
But if I tried to quit drinking, I wonder if my appetite would change. I have in the past, and sweets became much more tempting -- but I'm not the type of person who would eat candy bars all day and I almost never drink soda anymore.
Also, my phone tracks my miles and I see a fitness person once a week and report my food intake (not my drinking) in a journal and I add the miles I walk each day. I get a kick out of it and I'm proud when I have gone over three-four miles.
But it doesn't seem to change anything.
