"I Don't Have Self-Control..."
One of the obsession with nutrition over the years has been the tenet of “self-control” or “willpower.” Similarly, most patients initially complain that their problem is, “I just don’t have any self control.” It leaves me wondering, what exactly IS this oh so elusive “self-control” we all desire? And how do we strengthen it?
We have many common names for willpower: determination, drive, resolve, self-discipline, self-control. But psychologists characterize willpower, or self-control, in more specific ways. According to most psychological scientists, willpower can be defined as:
- The ability to delay gratification, resisting short-term temptations in order to meet long-term goals.
- The capacity to override an unwanted thought, feeling or impulse.
- The ability to employ a “cool” cognitive system of behavior rather than a “hot” emotional system.
- Conscious, effortful regulation of the self by the self.
- A limited resource capable of being depleted.
The “marshmallow test” was my first formal introduction to the idea of willpower. It is a famous social science experiment conducted by Walter Mischel from Stanford in the 1960s. His team put a pre-school aged child alone in a room and gave them a marshmallow. The children were instructed if they went 15 minutes without eating it, they could have a 2nd marshmallow. Some kiddos could wait and others could not. The team tracked the ~90 children to see how their behaviors correlated with later successes in life.
They found that those who delayed gratification with the marshmallow were more successful later in life. Sounds like a neat little package, right? Believing that self-control is behavioral – you either have it or you don’t.
HOWEVER, Tyler Watts from NYU and UC Irvine researchers later repeated the experiment in the 1990s with >900 children and accounted for variables such as race, ethnicity, parental education, and financial status. They found that self control (and later success) was more-so shaped in large part to the child’s social and economic background and not necessarily a “behavior” to be controlled.
So in essence, the child’s ability to “control” themselves around food and delay gratification had more to do with whether or not food (or even opportunity) was scarce than it did with their inherent ability to control themselves.
When food is limited by choice, belief, or situation…it’s less of an issue of “self-control” or “will-power” and more about circumstance
Restriction by another name
“…choose the ‘right’ food…”
“…to stop eating when they’re ‘supposed to’…”
Consider another signal
Hunger is so fear and shame driven by our society, so let’s look at it from another physical signal such as the need to go to the bathroom. When your body sends a signal that you have to pee, sometimes it is reasonable and necessary to ignore / delay honoring the signal – perhaps you can’t step away, the bathroom isn’t accessible, and/or it’s not urgent “enough.” However, ultimately, you will end up in the bathroom and fully empty your bladder (or risk some ridiculous pain / soiling yourself).
But would you ever shame yourself or someone else by saying, “I have no self-control because I have to go to the bathroom”? Or “I have no self-control because I can’t stop mid-way through going to the bathroom”? Or “I shouldn’t completely empty my bladder because of my body size”? Or “There’s clearly something wrong with me because I have to pee and he doesn’t”?
Absolutely not. We recognize and accept that our body speaks to us and has individual needs to be honored. We don’t believe we should be able to control our behavior despite what our body needs.
People believe that self-control is
the ability to make a food choice REGARDLESS
of signals from the body and mind
Self-control vs Deprivation
Our body (and mind) doesn’t know the difference between circumstantial restriction (eg, famine, poverty) and intentional restriction (eg, dieting, good/bad food). Humans are a species designed to thrive. So in situations of starvation / restriction, its reaction is the same – increased fixation on food, increased appetite, increased portions, decreased energy expenditure. Ancel Keys is most notable for his work exploring how starvation affects the human body (and spirit). It also gives me concern about the pressure we put on patients who live or come from situations of poverty to “eat better.” Is it realistic (or even ethical) to restrict food when there isn’t much “choice” to begin with? This previous blog post explores how circumstance can affect the ability to make health “choice.”
Interestingly enough, restriction can affect people for generations to come – both metabolically and behaviorally. Metabolically, future generations are more likely to exhibit insulin resistance and increased weight (decent summary here). Behaviorally, those who have experienced restriction are conditioned to eat regardless of despite hunger/fullness signals and encourage others to do the same “just in case” the food might run out.
Most people in the United States and the world aren’t too far away from a state of starvation – wars, depressions, and famines aren’t far down the line in many families. When food / types of food are rationed, we are forced to stop eating before feeling satisfied. Then when food is available, we eat beyond the point of comfort because you never know when the next meal will be. Both circumstances make it hard to make “choices” about food. When our upbringing comes from a place of poor foundation, it’s helpful to recognize those circumstances don’t still exist. (side note: sounds a little like dieting, right?)
