High fat diet does not increase calorie intake provided calorie density the same

High fat diets tend to increase calorie intake according to a lot of research. However, a high fat diet may not increase calorie intake more than a low fat or medium fat diet provided the calorie density of the foods are similar.
This is according to a study of six normal-weight healthy men who were allowed to eat diets that were low fat (20 percent), medium fat (40 percent) and high fat (60 percent).
The daily calorie intakes were 2554 for those on the low fat diet, 2633 for those on the medium fat diet, and 2604 for those on the high fat diet.
All diets contained 12 percent protein.
It would be interesting to see this study repeated with obese subjects.
Calorie density is the amount of calories for a given amount of food.
