We check in with the Packard Program

Juliana and I visited with the staff from the Packard Program yesterday.  They are doing great good in the world trying to help obese kids achieve a healthy weight, and they have good success.  Nonetheless, I believe that the calories in/calories out model that underlies the program is wrong.  So why does it work as well it as it does?

The Packard Program teaches kids to substitute lower-calorie yellow or green foods for higher-calorie red foods.  In many cases, those substitutions are from super-high-carb foods to less-high-carb foods.

From a glass of apple juice, for example, to an apple.  8 ounces of apple juice has about 29 grams of carbs; one medium apple has about 16 grams of carbs and it also has 4 grams of fiber, for only 12 grams of “net carbs.”  (When counting carbs, you subtract the fiber grams from the total carbohydrate grams, because fiber does not provoke the same insulin response).

Or from a high-sugar cereal to a low-sugar cereal.   Changing from raisin bran (36 grams of net carbs per cup) to cheerios (19 grams of net carbs per cup) cuts the carb load almost in half.

Both those substitutions are lower calorie changes, but they are also lower-carb changes.  So is it the carbs, or the calories?   I think it’s the carbs.  See chapters 19 and 20 of Gary Taubes‘ “Good Calories, Bad Calories” for a full discussion of this point.

The real power of the realization that carbohydrate restriction is the most important part of the eating plan is that your child will not be constantly hungry on a low carb plan, as they will be on a low calorie “balanced” plan.  At Packard yesterday I really emphasized this point:  Juliana complied perfectly with the program and did lose 6 pounds in 10 weeks.  But she was hungry all the time and I didn’t see how she could possibly keep it up.

A low carb eating plan doesn’t require superhuman restraint to follow.  That makes it a lot easier to coach your child on a low carb eating plan than a low calorie eating plan.

After losing a lot of weight in the beginning, Juliana’s weight loss rate has slowed on the low carb eating plan.  But even if she only loses an average of a 1/2 pound a week, as she did on the Packard Program, she will eventually get to her goal weight WITHOUT suffering constant hunger.  And in the meanwhile, her energy level is high, she has a completely new level of physical stamina, and her mood is consistently good.
