How can I help with his familys bad habit??

It usually depends on what your friend eats, but in general, pretty much most of the fast foods out there are not very healthy for you and should not be eaten on a regular basis. It won’t kill you to eat them once in a while, but a lot of the meals contain high levels of things that people don’t want to consume large amounts of (calories, fats, cholesterol, sodium, etc). In some cases, some of the meal combos have as much as you’d consume all day in just one meal. So these meals should ideally NOT be consumed a lot or extremely often.

With that being said, going to a fast food place often costs a lot more money than cooking a meal at home would. So I’m not really too sure if the money deal is their actual reason, or if it’s just a matter of knowing what to cook and where shopping would be more money saving.

So my suggestion would be to talk to your friend about it to explain your concerns. If they aren’t sure what to cook that won’t cost them a lot, you could always go online with your friend and Google things such as Meals under $10 or whatever their budget is. If you do that, you’ll find a lot of recipes and ideas on what they can cook. The meals are tasty, a lot healthier than fast food, and they would be a lot cheaper for your friend and his family.

I hope this works out for you.
