Sticking to the ultimate New Year's resolution: carbs are good and fat can be our friend if we would just learn to make nice with these vital macronutrients.

THERE HAVE BEEN the cabbage soup, grapefruit, low fat/no fat, and high-protein diets, as well as calorie-counting and no-calorie-counting programs--and let us not forget the do-note-at-late-at-night regimen and ... well, you get the idea. Americans always are looking for the magic bullet to weight loss. After being a clinical nutritionist for more than 20 years and having worked with thousands of clients, I can tell you that no magic bullet exists.

Although the U.S. is one of the richest and most technologically advanced countries in the world, there is a serious problem. Since the early 1980s, Americans increasingly have grown larger. We are eight pounds heavier, on average, than we were 15 years ago and consume 15% more calories today than in 1984. Adult obesity has doubled since 1980, increasing in every region of the U.S. in males, females, and across all age, race, and socioeconomic groups.

As the best-selling dress size for women grew from an 8 in the 1970s to a size 14 today, so have our risk factors for Type II diabetes, cardiovascular disease, stroke, high blood pressure, gall bladder disease, elevated cholesterol levels, osteoporosis, kidney failure, and certain cancers. Proper weight is not just a matter of looking good; it is about health. One study even suggests that obese adults have more chronic health problems than smokers, heavy drinkers, and the poor.

What are we doing wrong that allows for so many Americans to be either overweight or obese? Frankly, we simply are eating too much. Just ask the French, who are known for their rich, continental cuisine. Yet, the obesity epidemic is here in the U.S. In France, the croissants, glasses of wine, even portions served at McDonald's, are smaller than ours. Americans literally are killing themselves with their forks. In fact, funeral homes are selling larger caskets than they did in the 1970s.

It is the old bigger-is-better mindset and it is being ground into us on a daily basis. There is one advertisement that shows an overweight man getting blown across the room because he did not eat enough. The not-so-subtle message is that overeating is good and gorging yourself is acceptable.

The National Institutes of Health considers an individual with a body mass index of 25-29.9 to be overweight and a BMI of 30 or greater to be obese. Other accepted mathematical methods to determine if an individual is overweight or obese are weight-for-height charts, body fat proportions, and waist measurements. A much simpler approach is to accept the fact that an individual is obese when he or she weighs 20% or more than his or her ideal body weight as set by the weight-for-height charts. Regardless of the definitions and methods used to...
