There’s somehow this idea that to lose weight, one needs to eat “healthy food” and that costs more. That’s a whole load of crap! Perpetrated by those who want to profit from the ill informed.
It’s a matter of eating less (which is actually enough), coupled with exercise. Everything consumed should be in moderation. For the occasional binge, exercise more. A lot more. So if you’re eating less, shouldn’t it cost less?
There’s is really no need for all the fads of specialty diets. No need for some miracle “weight loss” chemicals.
But I have heard of an interesting explanation from a friend though. He never could find the motivation to eat less, exercise more. Instead, he found it works when it hurts his pocket. So he signed onto a programme. Because he has to pay for it, he felt compelled to follow through. I guess that’s one way.
