De-novo lipogenisis from sugar in practice does not happen humans. If you do something goofy like keep dietary fat under 5 grams and eat hundreds of grams of carbohydrate some monounsaturated fats can be synthesized, but it's fair to say that it basically doesn't happen.
Any fat on your body came directly from fats you ate. Sugar and carbohydrate only matter with regard to weight loss to the extent they displace fat metabolism.

In terms of fattening macro-nutrients, the rank would be fat > sugars > protein.
People keep ignoring this simple fact (that fat is already fat after all), yet argue endlessly about physiological stuff and ancestor mumbo jumbo.
