If by "dieting" you mean a temporary regimen of eating measured portions of
raw veggies and expensive, funny-tasting "dietetic" foods, then the answer
is yes. Your goal should be to adopt healthy eating and exercise plans that
you can live with for the rest of your life; these two factors can
be enough to cause gradual weight loss in most overweight people, without
the need for regimented diets. And these plans will serve you well after
you've lost the weight, too--most of us who have successfully maintained our
weight losses find that we can eat whatever amounts of low-fat, nutritious
foods (whole grains, fresh fruits and vegetables, low-fat dairy products,
legumes, etc.) we need to satisfy our hunger, without regaining the weight.
There's no need to deny real hunger pangs, so long as you satisfy them with
healthy foods. Note that it is possible to lose weight (without changing
your eating habits) by increasing youractivity levels dramatically, although
this approach won't necessarily makeyou healthier.
