Hi Spycar,

From your response it appears that you misinterpreted my intent. I didn’t say fats are non essential, I said to remove non essential fats. A certain amount of fat is essential to meet essential fatty acids and allow for fat soluble vitamin absorption. After meeting those needs the balance just serves as a calorie source and as such can be trimmed for weight loss.

Are you referring to Reynolds and Taylor’s work? If so seems you are misapplying it here.
As you reported much of the work on metabolism has been funded by pet food companies. A clue that the results of this work doesn’t support a recommendation of preferentially removing carbs and for weight loss is that the weight loss diets made by the companies doing the research are low fat.

Have you read Borne’s paper on weight loss? Keeping the percentage of calories from protein the same and altering the fat and carb content, the dogs on the higher carb, lower fat diet lost more weight and a greater percentage of body fat then those on the lower carb, higher fat diet.
