Overeating is wasteful. Most people only require between 1200 and 2000 calories per day to maintain a healthy weight. If you consume more calories than you require for weight maintenance, you are wasting money, time, and resources (both the food you eat and the packaging it comes in).
Think about it. I have. And no matter how you look at it, this statement is fundamentally true. If I splurge and "treat" myself with junk food, I am wasting the money I spent to buy the ice cream, for example, the ice cream itself (which is serving no useful purpose other than to make me fat), and the resources used to produce the packaging and the product, and all for something that I ultimately don't want: extra weight. And, that extra weight causes me to need to purchase larger clothes. Again, a waste, considering all the clothes that I have that fit me when I am at my healthy weight.
By consuming only enough calories to maintain health and weight, I am also going to be choosing fewer packaged items, saving money and resources. By not having seconds at dinner, even if we have plenty, means I both stay within my calorie range and have enough for lunch the next day.
There are probably more examples of this, but this entry should be enough to get you all thinking. I've been pondering and planning this blog entry for a while, but wanted to wait until I was ready to walk the walk as well as talk the talk. Today is that day: I am recommitting myself to correct eating principles (can't say it's a "diet," because it is how I am going to eat forever) and exercise. And I am making sure that all of you know it. Please feel free to ask how it's going.
