Sweet Justification

26 Apr

I have a confession: I eat dessert for breakfast all the time. Especially cookies, but I occasionally go for pie, cake, or whatever sugar-loaded food happens to be around. When Girl Scout cookies are in season, I eat Tagalongs for breakfast every day, for weeks. (I figure they’re healthier than the other kinds because of all the protein in the peanut butter. Right?) Whenever I behave myself and eat “real” breakfast items, they’re just desserts in disguise: Fruity Pebbles, sugary granola bars, cheerios with chocolate chips mixed in. Ted’s family-size box of Grape Nuts almost can’t stand to share a pantry with my breakfast food.

But now, thanks to SCIENCE, I no longer have to be ashamed of my breakfast choices. A recent study by Jakubowicz, Froy, Wainstein, and Boaz (2012) randomly assigned obese, sedentary, non-diabetic participants (n=193) to one of two groups: a group instructed to eat a high-carbohydrate, high-protein breakfast that included a dessert, and a group that ate a low-carbohydrate breakfast that did not include a dessert. All participants were placed on an isocaloric diet, and the groups differed only in their breakfast assignment. While there were no significant differences in weight loss between the  two groups at the end of the diet intervention, participants in the group who had eaten a dessert as part of breakfast continued to lose weight weeks after the intervention ended, and weight regain was observed only in the group that did not eat a dessert in the morning. Participants who had a dessert at breakfast also reported significantly lower hunger and fewer cravings.

The authors suggested that this surprising finding may be attributable to reduced reinforcer value: that is, when you get a dessert every morning, it loses some of its “specialness,” and cravings don’t occur as often. As noted by Jakubowicz et al., “In many weight loss diets, energy is restricted concomitantly with the restricted intake of preferred foods, leading to an increase in the reinforcement value of the omitted or restricted food. This may be expressed as increased cravings for the desired food. In contrast, repeated reinforcer presentation leads to a reduction of reinforcer efficacy and reduced motivation to obtain the desired food. It is possible that the consumption of sweets at breakfast in the [dessert] diet group (chocolate bar, chocolate mousse, cake, or donut) represents repeated reinforcement leading to reduced cravings” (2012).

Take THAT, Grape Nuts! This study proves* that I’m making choices that support a healthy weight! Can’t wait for science to find support for all my other bad habits.

*SOME people might say that one study does not constitute a body of proof. But I can’t hear what they’re saying because this cookie I’m eating is very crunchy and it drowns out all sounds.

Proposed!

4 Dec

Knocked out another graduate milestone this Thursday and proposed my dissertation!

Here’s how proposals work in my program. You write up a lit review and research plan in the ballpark of 40-50 pages, get your adviser’s thumbs-up, distribute copies to your four-person committee, attempt to schedule a 1.5-hour block that works for all four committee members, weep because they have no 1.5-hour block in common in the next month and how will you ever herd these people into a room together?, and find a 1.5-hour block that everyone has in common. Then you treat your committee to a 10-minute PowerPoint presentation, desperately try to mask your limited understanding of bias-corrected bootstrap methods, fail to do so, and sheepishly write down your committee’s advice. That’s it. You don’t have to bring doughnuts. It’s basically impossible not to get your committee’s approval. But there are ample opportunities to sound stupid, which is what makes proposals so scary.

I celebrated the survival of mine with a How I Met Your Mother marathon. Aaaaand am still celebrating, thanks to the celebration-extending properties of Netflix. Also, I ate a cupcake for breakfast on Friday. I’m the kind of girl who knows how to party.

I guess now I actually have to write the dissertation.
