Why do we have an obesity epidemic in the US? Portion size is a big part of it.
Whenever I travel to Europe or Australia, portions are smaller. Smaller portions are good for those of us leading mostly sedentary lifestyles, and they are good for the environment. Food waste, as I discuss in the book, is a huge target if we want to reduce greenhouse gas production, water use, and preserve natural landscapes. But you could similarly argue that eating more than is needed is a form of waste as well.
Why do we eat so much? Partly a function of plate size and serving size. We eat more if our servings are bigger. We eat more if our plates are bigger. We eat and drink more if plates and glasses are constantly re-filled. Ironically, it's the first few bites of any food that are the most enjoyable. That's why I suggest serving lots of small 'tapas' at a dinner party.
By eating mindfully, and therefore eating less, we're doing something good for us, and also something good for the environment.
Discussion questions: How could you eat more mindfully? How far does this extend? Should we be concerned about what we're eating in addition to how much we're eating?
