People want to eat what they want when they want it but think they can work it off with some exercise.
It’s a numbers game.
The truth, the uncomfortable truth, is that calorie restriction is the only practical way to lose weight. The average adult needs 1800-2000 calories to maintain their weight. Each 3500-calorie deficit can produce one pound of weight loss. One hour’s exercise burns 175 calories (cooking), 220 calories (bowling), 300 calories (push mowing) and 500 calories (high impact aerobics), while one cookie in many restaurants can amount to more than 400 calories and a scoop of ice cream 140-200 calories. You really are what you eat.
