Diet for weight loss; exercise for fitness.
You can meticulously count every single Jelly Bean or lick of peanut butter you’ve had, then calculate the number of calories you’ve burned to offset them. But this actually hurts your weight loss efforts (and sanity) more than it helps. Here’s why you shouldn’t rely on “calories in” and “calories out”.
While many of these points are valid, I think a better way to summarize this is that many people misstate their calories when calorie counting and not as much that there are inherent problems with calorie counting. It takes discipline not only to eat better, but to track it all as well. If you start to take shortcuts on tracking or are being liberal with how big that scoop of peanut butter is that you counted as one serving, then you’re only doing it to yourself.
Calorie counting isn’t for everyone, but it can work for the right type of people.
