How long have you been on keto? I am not a fan of keto diets, I'll just say that outright. Anything that is too restrictive for too long will not end well. I am unsure of how being a broke college student would hinder your ability to eat carbohydrates, though. That is a serious question, not a mean one, I promise! I just don't see why you can't eat carbohydrates on a budget. If you're talking about food and nourishing yourself, it's worth it. I have never been and will never be an advocate of a diet that virtually eliminates an entire macronutrient group. It is not substantial, nor is it healthy. Might it work for fat loss? Sure. But it's not sustainable and it's not good for you, in my very honest opinion.
