Do 'Slow Metabolisms' Exist? What Does The Science ACTUALLY Say?

Do 'slow metabolisms' actually exist?

It is commonly claimed that people who struggle to lose weight have a 'slow metabolism' or 'metabolic damage', and we know from an abundance of research that the likelihood is they are simply misreporting their energy intake.

It is VERY hard to accurately calculate how much energy you are consuming and burning, so it makes sense that people do not get this accurate very often.

However, this has caused a bit of an overreaction, and many people claim that slow metabolic rates don't exist.

Well, it depends on your definition of 'slow', because we have a lot of research showing that slower metabolic rates definitely exist.

Two people could have the same height and weight but one could burn a lot less energy than the other. Even if they have the same amount of muscle mass, one could burn far less energy than the other.

So, it's smart to know that:
1) 'Metabolic damage' is often overstated, and simply a result of people underreporting their food intake
2) However, this doesn't mean that interindividual variance doesn't exist. Humans are complex little buggers so it makes sense that some of us burn slightly more or less energy.

Make sense?
