Moreover, changing one's habits to cooking requires effort upfront, and its benefits may not be apparent (at least in the start).
If there is one thing I know for sure is that there is very little benefits in cooking, apart from the pleasure of eating something good. Even if you want to eat healthy there are plenty of ways that require very little cooking. The only problem is how much money you can throw at the problem, the easier it is the more expensive it will be. Sometimes you don't even have a choice because of time constraints (people who do 2 hours commute everyday just can't allocate time to that).
If you do not have the money to order on the daily, then you either cook or someone else has to do the cooking.
