Do you know what happens when you break your leg but keep walking on it without going to a doctor? It keeps causing damage, until that damage is irreparable and there's a bone hanging out of your useless leg. That's pretty easy to visualize, yeah? It's harder to imagine the same thing going on but mentally. It's hard to see the true damage that repeated exposure to stressful situations causes to your mind and psyche. Sure, sugar bombs do damage. So does working until you're in fact passing out on the floor.
Your rah-rah attitude might work for you, and I'm glad for that. But before you go all motivational speaker on everyone else, maybe consider that other people aren't as mentally strong as you seem to be. Some people can't carry a 50lb weight 24x7 for days on end. Likewise some people can't carry the mental weight of two jobs, a family, and bills still being unpaid plus the thought of working for hours when they get home to make a meal.
I just got here in passing, and I have to admit I'm kind on the side of ctdonath here. Currently, I'm working 3 jobs (one is 6 hours a day, the other two are two projects I'm working on that are 2-4 hours a day, total.) In addition to this, I'm finishing my PhD (or trying, time is scarce lately) but I still find the 10-15 minutes it takes to open the gas stove and prepare some sauteed vegetables, the 10 minutes it takes to prepare a lettuce and lots-o-more-things salad, or the 5 minutes it takes to prepare crispy bacon.
The "cooking for hours" mentality is bullshit. With the rest of your points I can agree (as well as I agree with ctdonath's points,) since there is no universal truth in what people are doing with their time, and how much they can endure. But with the waste of time cooking takes, I just can't. It's false. I've cooked 3 course meals for 8 people on special occasions (so it's more elaborate than usual) and only in this case it took me more than 30 minutes to do it. It was 1h30. Of course this may seem like a lot, but I don't do custard everyday and it takes quite a long time.
Well it's kind of a false equivalency to try to say that 30 minutes cooking dinner is the same as 30 minutes preparing convenience food. Cooking meat, cooking beans, cooking rice, sauteing veggies, preparing a salad, whatever, is not the same as putting a frozen lasagna in the oven for 30 minutes while you veg out on the couch and unwind.
Sure, it's 30 minutes, but what really counts is what you're doing in that 30 minutes. If you're watching your food, you're working. If you're watching TV while your food cooks to the tune of the prepared directions, that's completely different. That doesn't even take into account the time spent at the store picking out individual ingredients vs just grabbing a frozen meal and running out the door.
I'm not defending poor eating habits, at least I'm not trying to. The point of my post was to point out how self-righteous ctdonath is being in the majority of his posts in this topic. "You're not tired unless you're passing out standing up" is just bullshit. Mental stress is a real thing, and it cannot be discounted. I don't know you, but I can guess that if you're doing a PhD, you have what it takes to handle significant amounts of mental stress. You have to, or you wouldn't have even gotten through undergrad with the will to pursue two more difficult degrees. Your single parent dual factory worker who grew up in a blue collar family and sees no prospect for future success might not have that same level of motivation, which is why I called out ctdonath for being a motivational speaker.
What works for you will not work for everyone. It's difficult to see mental injury and duress. Stress is not as visible as a broken leg, nor as easy to treat. People should eat proper, yes, but telling them "it's not hard, you're just lazy" is by far not the proper way to get them motivated.
I don't think 30 minutes preparing a meal is the same as having it done. It's really completely different... I'm not perfect at this either, and sometimes the tradeoff of 30 minutes to prepare something is too big and I just do something quicker (rarely prepared food, but I love bread with olive oil and cheese, so it feels great for me when I'm not in the mood for cooking.)
It all depends on how you value those 30 minutes. If there's something in TV you want to watch and will make you happier/more energetic, it probably is worth the extra cost prepared food has. If you are just watching some nonsense to disconnect your brain... Well, stirring a pot is also quite a zen experience, far better than most TV programs :D
