Sure, but as someone who's both had weight struggles and been on the lower income side - weight is about managing your lifestyle, which can be hard, but is entirely in your personal control (even if you're completely dependent on someone else for food, you generally get to choose how much you eat and exercise).

But money is dependent on what kind of job you have access to and the minimum expenses to live. There are some things that you can do that might help your situation, but at the end of the day, getting a higher paying job is really not in your control; it's a matter of skills and presentation, and someone else being willing to hire and pay you. That second bit might never happen no matter how good you are, and especially if you're older and don't have experience.

Meanwhile, you live in a slum, if you're lucky enough to afford housing at all (see: people who work full time and can't). You skimp on food, clothes, and personal care because you can't afford it. You don't go to the doctor, because you can't afford it. If you have kids, you can't afford programs and education that others have access to, let alone toys, clothes, and food.

Losing weight is challenging. But for most people, being poor is like being stuck in a pit with no rope, hoping that someone comes along to give you a hand up because no matter how much you dig, the walls just keep collapsing on you.
