This thread disturbs me. I studied clinical nutrition in college and I am the mother of a 15 year old who gained a large amount of weight very quickly beginning around age 10. We explained to his pediatrician that he does not overeat. He gets exercise. He does not drink sugary beverages. Ironically...he really doesn't show much interest in food. I shared with her his frustration at being judged as a lazy teenager who stuffs his face...when nothing could be further than the truth. His pediatrician explained that he most likely has insulin resistance (hyperinsulinemia). Insulin (a hormone) is highly involved in fat storage and the hormonal changes of oncoming puberty often cause a significant weight gain for those with this problem...and it continues through adulthood. She explained that she has two sons, one who eats a lot and is thin, the other eats less and struggles with his weight. They are both very active. She shared that within the next ten years there will be a big change in the way we understand why people are overweight. It is very likely that" hyperinsulinemia" is the genetic "cart" before the "horse" of obesity. The medical community's wheels are slow to turn when they find that what they have been recommending (low fat - lots of "good" carbohydrates) is actually contributing to the problem instead of helping solve it.
She validated my son...and the truth about what and how much he eats. My son is not the only person in my family that is insulin resistant. His doctor explained that there is almost certainly a genetic component. Before there was a stable food supply it was the people with this genetic make up that survived extensive periods of famine.
Two months ago my son went on a high fat (including saturated fat) - moderate protein - low carbohydrate
diet (all carbohydrates - even good ones - break down into glucose/sugar, which stimulates insulin secretion). This
diet has NO calorie restrictions but it does limit the carbs to 50 grams per day (fiber does not count toward daily total). In two months he has lost thirty pounds and his numbers are great. It should be noted that what he eats is pretty much opposite of what the federal government recommends he should eat. I am glad that his pediatrician does not work for the FDA.
We need to be careful about the spiritual conclusions we draw regarding people who are overweight.
Sincerely,
Cynthia
