By the way, one of the most effective ways, based on my experience, on losing body fat and making yourself fit and trim in the process is to engage in free climbing. Have you noticed how fit most of these mountaineers you meet are? They eat (I know this from experience, too, as I used to do mountaineering years ago) humongous meals, and they eat just about anything (in addition to those recommended by their healthcare provider). You don't really have to be copycats of any those guys mentioned in the image here. You can go to any indoor climbing gyms. I believe some gyms have this kind of set-up. I once had a multi-day climb up in the Mt Halcon mountain range in Mindoro, Philippines years ago. Part of it entailed doing 'vertical' free climbing. When I came back to the city, I saw how much weight I lost, and my love handles along my belly area were gone. Hence, I recommend free climbing to all of you out there bent on losing weight and making yourself look trim and fit like an adolescent dude. Of course, you can find other ways to do this.
In the meantime, enjoy life.
