A lot of you may not take this seriously, but hear me out. Using smaller dishes will actually help you eat less - and you will never notice the difference.
It's true. How do I know? Two sources: science and my own experience.
The Science
Cornell researchers demonstrated that people "given larger bowls served and consumed 16% more cereal than those given smaller bowls." Worse, despite this, the people given the larger bowls actually thought they had eaten less than those with the smaller ones. (Follow the link; the wine glass demonstration at the end of the second video will convince you.)
Even experts fall for this optical illusion. A study published in the American Journal of Preventative Medicine conducted on 85 nutrition experts at an ice cream social showed that when these experts "were given a larger bowl, they served themselves 31.0% more without being aware of it."
Now you might be thinking, "Well, I have normal-sized dishes so how does this apply to me?" Not so fast. A study published in the Journal of the American Medical Association found that portion sizes in American homes and fast food restaurants have "increased markedly" since the 1970s. (By 22% since 1960, according to Brian Wansink at Cornell.) If you didn't inherit all of your dishware from your grandmother, it's probably not helping you maintain a healthy weight.
My Own Experience
A single brownie, one spoon of chocolate sauce and 2-3 spoons of vanilla ice cream fill this small salsa dish and satisfy my cravings without busting my waistlineOne of my biggest vulnerabilities is desserts like ice cream and sweet snacks like chocolate-covered nuts and dried fruits. I know enough to portion them out into a dish so I don't just keep eating and eating, but I know I tend to dish out more than I really need.
Over time, I've used smaller and smaller dishes and this has helped me reduce the amount I eat in a serving. For ice cream, I've gone from a cereal bowl (almost 6" across) to what they actually call an "ice cream dish" (4.5") to a salsa dish (3.5"). And for chocolate-covered snacks, I've gone from the salsa dish to a custard dish (beveled 3.5").
When I'm done, I rarely look back. I've found that the satisfaction from food comes in the first few bites when I am really experiencing the flavor and the texture in my mouth. After that, I am really just finishing what's in the dish. It's hard to anticipate that when I am scooping out the ice cream, though, and it looks so good. That's where the small dish comes in. It actually looks like more if it's filling the container so it makes it easier for me to serve myself less and feel like I am going to be satisfied.
And lo and behold, my expectations are almost always met. A mini brownie sundae consisting of one homemade brownie with a single spoonful of chocolate sauce (heated together in the microwave for 20 seconds) and topped with a 2-3 spoonfuls of vanilla ice cream (yeah, the real stuff) feels like a real indulgence to me, at least partly because it fills my salsa dish to near overflowing.
This fits with my strategies of more, smaller meals and of planning for indulgences. Oh, and man that vanilla creaminess melting into that hot dark chocolate is fantastic - for about the 5 bites it takes me to finish this snack. After that, it's just calories.
