but most people who are single digit bf% are bodybuilders who are eating mostly protein, so pretty much the opposite of your diet.
Those bodybuilders are on steroids, AND they're abstaining from fats. So half of what you stated (abstaining from fats) supports my argument that a low fat diet helps keep body fat percentage low, and the other (flawed) half of your posit is their illicit practice of steroids in order to build muscle and burn more fat. That's not an affirmation of efficacy of a high animal protein diet. High testosterone burns body fat. If high animal protein, alone, was enough to build the type of muscle they wanted, they wouldn't need steroids. You lose, again.
Therefore the idea that your diet is the only way to achieve single digit bf% isn't very accurate.
It's the best way.
There are people with an abnormally high metabolism who can eat fats, oils, and excess animal protein all day long, but still keep a lean body. It's very rare. I'm not one of those persons as my opponents would like to wish because that wouldn't lend support to my promulgation of a high carb/sugar and low fat/oil/animal protein diet. The fact is I've strayed away from a high carb/sugar diet on several occasions while eating a lot more fats & animal protein, and I gained 30-35 pounds of mostly fat, all while mostly still being engaged in the same physical activities. But it wasn't a problem because each time I soon went back to a high carb/sugar and low fat/oils/animal protein diet, and I lost all of that body fat. It wasn't until I learned about the sugar studies that such diets resonated with me, although I instinctively knew about it.
If there's no such thing as a sugar addiction then what do people get addicted to in Coke? It's pretty much all sugar.
It's called addiction to caffeine. Also, there is high fructose corn syrup in soda, not regular corn syrup. The former is a destroyer. The latter is completely fine (barring any adverse effects from GMOs). You lose, again.
I'm interested in seeing your studies on calorie restriction not mattering for high carb diets though. People often say that weight loss/gain is just a matter of calorie in vs calorie out, and I've often distrusted that, but I've never actually seen a paper on it.
You and Ladislaus have already demonstrated that you don't want to know the truth. You still reject it in spite of the evidence brought to you. I've already posted vid of a doctor who cited scientists and another doctor. I've, also, posted a number of studies on a different thread that support my argument. Go look for it.
Bottom line, ANY fat that you eat, you wear that same fat. No matter how little or large the consumption. That fat is immediately stored as fat in the body. The argument that you burn fat for energy if the person restricts carbs/sugar is flawed because sugar is a far more efficient fuel for the body and brain. The physical and mental performance gains and endurance is far more from burning carbs/sugar than burning fats. The fact is it takes a lot longer to burn the fat. Example: a person on keto (high fat, low carb/sugar) diet runs at less speed and distance than a person on a high carb/sugar diet, and that person on a high fat and low carb/sugar diet will bonk ("hit the wall") much sooner than a person on a high carb/sugar and low fat diet, all while the person using the sugar as fuel isn't storing much body fat because his diet is low in it. To replenish fuel, the person simply eats more carbs/sugar. Try eating fats when you're nearing the threshold of exhaustion, and see where it gets you. Nowhere. You'll still bonk, and you'll still have body fat because the remaining fat in the body didn't get burned as fuel.
