I heard this bit on Weekend Edition Sunday this morning about new studies about the science behind willpower. According to a new book, called Willpower, by Roy F. Baumeister and John Tierney, willpower is more than just a state of mind; it's an actual function of the brain. And interestingly enough, it's a function that depends on having enough glucose circulating in your blood stream.
In the interview, Tierney said a couple of interesting things about how willpower works that stood out to me. He described how it's much easier to exert willpower to resist the temptation to eat a cookie if the cookie is out of sight. You're more likely to eat some Oreos if they're sitting in front of you than if they are hidden away in a drawer across the room. When asked about willpower and dieting, Tierney explained that one reason dieting is so hard is because it usually involves taking in less food than one is used to eating, and less food means lower levels of glucose, which means willpower can't function the way it's supposed to. "In order to diet you need willpower," Tierney said, "but in order to have willpower, you need to eat."
These two points of Tierney's speak exactly to principles underlying my whole system of shopping and menu planning. To start with, don't buy things that you know you wouldn't be able to resist if they were in your house. Sometimes I crave ice cream, or something like that, but that craving is pretty easy to resist when I don't have it around. More importantly, though, you need to eat. Eating healthfully doesn't mean eating less. In my case, I've found it actually means eating more, but eating better. More protein, veggies, and fruit. Changing my diet turned out to be surprisingly easy, at least in terms of my enjoyment of food. When I have good food in the fridge that's ready to eat, I don't find myself wishing I had a quesadilla or a slice of pizza instead. The somewhat more challenging part was learning to plan ahead, and to get used to making time to cook things more complicated than burritos or tuna melts. I suspect that this is really the hardest part for most people. It's not the idea of changing what you eat, it's changing how you eat--that is, how you tend to shop during the week and what you usually do about making dinner after a long day--that's hard. Planning makes all the difference.
So how do you come up with a plan? Well, I think you have to let food be the motivating factor. You should think about the meals that you really enjoy, and that you know how to make. (Maybe you don't know how to make many things; that's a problem unto itself that I will need to address in a different post. I always say, however, that if you can read, you can cook. I think that a lot of cooking failures, my own included, are the result of not reading a recipe attentively. Just following the directions carefully is usually all good cooking takes.) Think about it this way, if it helps: if you were going to go out to eat all week, what kind of restaurants would you like to go to? Thai? Italian? Mexican? OK. So, is there anything you get at that kind of place you could make on your own? The answer is often "yes." A simple example is your basic taco, that you can get from any taqueria, which is just a corn tortilla, some spiced meat filling, topped with chopped onion, cilantro, salsa, and lime juice. This is one tasty meal that is about as easy to make at home as it is to go to a restaurant and order it. And you can dress it up or down as much as you want. Anyway. Can you come up with three or four things you wouldn't mind eating throughout the week? Alright, then, you've got a menu.
Once you've got a menu, it's fairly easy to come up with a shopping list to get the things you need. Even if you have a menu that's kind of complicated and disparate, and requires a weird mix of items, don't let this intimidate you. It's far better, I think, to spend more money in one go, knowing where that money is going, than to shop frequently and randomly--buying fruits or vegetables you have no clear plan for that end up going bad, buying bread that languishes until it's moldy or stale, buying staples haphazardly so you end up with dozens of cans of something you use infrequently while you never seem to have enough pasta or rice on hand, etc. Make a shopping list, get everything that is on it, and don't get anything that isn't on it.
Getting motivated to cook is the hardest part. You need to think of cooking as a necessary task that needs to be done regularly, just like laundry, or cleaning the bathroom. And just like laundry and cleaning the bathroom, cooking need not be something you do every day. If you want to make something complicated, make it on your day off, and on the nights when you have no energy for cooking you don't have to do anything but reheat it. In addition, having an arsenal of simple, quick, tasty recipes at your disposal, like the pesto pasta I made the other night, or the succotash, or those tacos I mentioned earlier, is great, because you can throw them together anytime without a lot of effort. The key is to make things in the proper quantity. Make enough of something that you can get some leftovers out of it, but not so much that it will go bad before you finish it. Most of the recipes you'll see on this blog will make about four servings, or enough for a person living alone to feed themselves four times throughout the week. If you live with someone, doubling the recipes for two may cost you a little more money, but the increase in time and effort will be negligible. I actually think shopping for two (assuming that you have two incomes) can be more economical, because buying things in bulk often means you pay less for something per ounce. That's why they call big packages of things "economy-sized."
So back to the willpower thing. A final thing John Tierney said about willpower is that you can build it up and train it, like muscle. With practice, you can develop stronger willpower over time. I have found this to be the case with me and cooking. It used to make me tired to even think about, but now I'm used to it and it doesn't seem like such a chore any more. In fact, I really enjoy it, to the extent that for me it can be a way of procrastinating from working on something else that needs to get done. Well, maybe it's not procrastinating. Maybe it's just my brain craving the food it needs in order to focus on my other work. Right?
