from what i've read, calorie restriction can help you live longer.
i also find it economical vs. "exercise"... because i simply eat less food. i don't overconsume food, and then have to "burn it off" via exercise. i don't spend extra time working out, running, going to the gym, etc. i don't obsess over counting calories or measuring my heart rate while exercising.
one of my cardinal rules is that i simply don't eat after 5 pm. it works to lose weight, and i also think it's more natural... b/ in all previous generations, before advent of electricity, people simply went to sleep when it got dark. i think our bodies are geared for NOT eating at night. so for overweight people in our modern world, this is an awesome time to burn calories and drop pounds -- fasting in the evening hours.
assuming that one lives a normal active life, including caring for young children, cleaning one's own house, going for walks, etc. --
what are the virtues of losing weight via exercise, instead of calorie restriction? am i missing something?
