This sounds radical, I know. But the truth is, most of us eat too much, albeit unwittingly. At a recent conference I attended–with an audience full of food service providers–most people had no idea how many calories an average person needed in a day (the answer is 2,000). And when we don't know how much we should be eating, we'll often just eat what's put in front of us . . . even if it's more than we need.
So for the next week, if you usually eat a bagel in the morning, bag half for the next day. If you eat a tuna sandwich for lunch, split it with a friend instead. Note both your weight and how you feel throughout the week–both physically and emotionally. Note, too, what you tend to compensate with if you do get hungry . . . but remember, whether it's a bag of chips or an apple, only eat half of what you normally do!
