Chances are that yes, it's absolutely normal, especially if all your other health factors are in order like you said.

Some people just have naturally higher heart rates than others.

Of course, to be absolutely sure, you should mention it at your next checkup.

I agree, I'm not placing the blame on the studies themselves, and I understand there are several factors contributing to both sides of the equation (overweight and underweight), but I still firmly believe that 99% of people are far too quick to find excuses.

If you want remarkable results, you need a remarkable effort, and if you have to push that much harder because of something out of your control, then that's just what you have to do.

Your quote: "It's very simple: YOU made yourself fat and unhealthy, and only YOU can change that!" — While I agree that everyone is ultimately responsible for making healthy changes in their life, there are a multitude of factors constantly interplaying with one another making this problem far more dynamic and difficult to manage.

Thanks!
