My position, and that of a growing number of researchers, is that there’s more to obesity than calorie balance, and that body weight and fat mass is regulated by a complex system that involves an array of hormones and feedback mechanisms.
In recent months I’ve become interested in the potential role of a hormone by the name of leptin in obesity.

It’s not “in the mind” in the sense that you can imagine your way to weight loss. But there’s definitely MORE to weight loss than the balance of calories. My experience is that the best way to lose weight is to simply reduce my calorie intakes slightly — no need to count everything and aim for a computed target intake. At the same time, include some strength training (a ton is not required, but walking/cardio is NOT what worked for me.)
