This study is contradicted by a study by Oste which showed that meat heated for 10 minutes at 130 °C (266 °F), showed a 1.5% decrease in protein digestibility:-

Also this study showed that similiar heating of hake meat in the presence of potato starch, soy oil, and salt caused a 6% decrease in amino acid content:-

The above are referred to on the anti-raw beyondveg.com of all places, which shows a refreshing scientific honesty.
Also, whether people gain weight or not does not necessarily mean that they are digesting particular foods better. I , for example, gain weight rather rapidly(with a potbelly etc.) if I eat small amounts of cooked animal foods on a regular basis and my stools are then much larger than when I'm 100% raw, suggesting poorer absorption of food. By contrast, eating cooked plant foods or raw foods in general does not lead to me so quickly gaining weight.
