Well sleep time for your body is "detox time". Body fat is one huge deposit of "toxines". This only gets burned when you "fast" / don't graze for a while and energy is obtained from those deposits. This alone would mean, more sleep = more burning. That's also why people doing one variation or another of "intermittent fasting" are getting great results, as they extend that phase well into daytime as well. I know I know, citation needed.

I've drastically reduced my carb intake and ramped up fat intake and I've lost weight and never feel tired.

  Sure! Dietary fat is pretty good for you and absolutely doesn't translate into body fat per se, that is influenced by many factors including carb intake.

    It seems to be metabolized (into glucose?) much more evenly than carbs.

      No, lipids are metabolized directly as lipids (via lipolysis). In the absence of sufficient dietary carbohydrate, some lipids may be transformed into ketone bodies via a process called ketosis, to provide an alternate fuel for the brain. This is what the Atkins and other very low carbohydrate (<~50-100g/day) diets seek to accomplish. Dietary carbohydrate (other than fructose) is directly metabolized by cells as glycogen. Two tissue types (brain and red blood cell) prefer glycogen, red blood cells require it. Your body can store about 200g of glycogen split between the liver (~100g) and skeletal muscle. Liver reserves can fuel any body function, muscle stores fuel just that muscle. Excess carbs are converted (by the liver) into fats, and stored as same via the insulin/glucagon endocrine balance. Look up the Krebs Cycle for more information. Dietary fats serve as long-term, low-rate fuel for skeletal muscle and organs (other than the brain and red blood cells), and is either metabolized directly or stored as adipose tissue. Dietary protein isn't metabolized directly. It's used for structural processes as its component amino acids, some of which can be synthesized by the body, but some (essential amino acids) cannot be, others are rate-limited to a degree that dietary supplementation is occasionally recommended. Protein (dietary or from body tissues) can be converted to glycogen through a process called gluconeogenesis. This occurs both in low-carb diets and during starvation.

To be clear, body fat itself is not an issue, but many toxic chemicals are fat-soluable and thus wind up sequestering in fat stores.
