diabetics can lose weight with portion control. Robert Preidt of HealthDay News reports:New research claims that
Over six months, about half of 122 patients (average age 56) used the portion-control plates and bowls, while the rest of the patients received usual care consisting of dietary assessments and teaching by dietitians.This is all well and good, but, Dr. Fuhrman doesn’t think portion control is a great idea. Actually, he finds it kind of futile. Here’s an example why, from Bad News for Portion Control:
The patients who used the portion-control plates and bowls lost an average of 1.8 percent of their body weight, compared to an average of 0.1 percent among those who received usual care.
The University of Calgary researchers also found that 16.9 percent of the patients who used the portion-control plates and bowls, which were donated by a U.K. company called The Diet Plate, lost at least 5 percent of their body weight, compared with 4.6 percent of patients who received usual care.
It is meaningless to compare foods by weight or portion size. Let me provide an example to explain why this is the case. Take one teaspoon of melted butter, which gets 100 percent of its calories from fat. If I take that teaspoon of butter and mix it in a glass of hot water, I can now say that it is 98 percent fat-free, by weight. One hundred percent of its calories are still from fat. It didn’t matter how much water or weight was added, did it?
