Skinny man kick vs fat man kick

They can be a huge determining factor- but not the determining factor by far in my experience. Mass is a powerful tool- but the composition of that weight determines things like speed. In general, someone who has to carry around more weight all day- fat or not- will have an advantage in untrained strength against a smaller untrained opponent of similar activity levels. They’ll have natural advantages in things like grapples and pins, inertia will be on their side and even without muscle they can hit like a freight train if they leverage their mass. They have more padding against internal injuries. Untrained though and at high BF they are often slower, less precise, and often tire faster. The joints, especially knees and ankles will be weak points. #1 advantage is always hunger, who wants or needs the win more. Next up will be experience, skill, and physical factors come last. But I will agree that in untrained fighters and unskilled fighting, the bigger one usually has the advantage.

If they can slim down without losing muscle yes. Catabolism occurs as the weight is lost but not replaced with resistance. Loss of fat requires a caloric deficit, which coupled with the above makes the body shed muscle it feels it doesn’t need anymore. A strict regiment is used by athletes who want to minimize muscle loss while cutting, and one of the major uses of steroids is to keep an anabolic state while cutting weight to achieve a sigh muscle content and low body fat which are impossible or very difficult naturally. Genetics plays a roll, but muscle requires extra calories to build and keep naturally. As a fun fact: people with shorter limbs tend to have stronger grip muscles even if they have weaker grips! The length of tendons and bones acts as a lever, so longer limbed people can exert less force to produce the same end grip strength as someone with shorter limbs who lacks mechanical advantage, so must produce the end grip strength using more muscular force. Wow. The human body
