Spycar,
I don’t see anything “scientifically” wrong with saying that not all fat is essential, just as not all protein being fed is essential. Once protein needs are met, the rest will be burned for energy. We need to meet the dog’s essential needs for protein and fat and energy.
Energy can come from protein, fat or carbohydrate.
Dogs don’t have an essential need for carbohydrate. People don’t either. Perhaps you don’t incorporate vegetables, fruits or whole grains in your diet, I do. You may think I will suffer from that choice as carbohydrates are not essential to humans.
In regards to optimal calories from fat I don’t think you’ll find any agreement on that topic. I’ve read that veterinary nutritionists prefer not to go above 40% calories fed as fat. I can confidently say if I had fed my fat intolerant dog the 50-60% calories as fat as you feel is optimal she would have died an untimely death.
You seem to be ignoring the data on this topic : Body composition studies, fat fed dog model, weight loss studies, satiety studies… why is that??
