People who eat whatever they want and stay slim have a slow metabolism, not fast. A skinny person tends to have less muscle mass than others, meaning their basal metabolic rate (BMR) is lower than those of a high muscle mass – this gives them a slow metabolism, not a fast one.
This sounds like a total "glitch in the matrix" fact because it’s the exact opposite of what we’ve been told for decades. We usually call slim people "fast burners," but biology tells a much more nuanced—and counterintuitive—story

The Science: Why "Slim" is "Slow"
The biggest factor in your metabolism is your body mass. Think of your body like a car engine:
A Large SUV (Larger Body): Requires a massive amount of fuel just to idle at a red light. A Small Scooter (Smaller Body): Requires very little fuel to keep the engine running.

Because a slim person has less tissue to maintain, fewer cells to oxygenate, and less weight to move around, their Basal Metabolic Rate (BMR)—the calories burned at rest—is actually lower (slower) than that of a larger person.

So why do they stay slim? It usually isn't a "magical" metabolism; it's often one of two things:
NEAT (Non-Exercise Activity Thermogenesis): Some people naturally fidget, pace, or stand more. These tiny movements can burn hundreds of extra calories a day without the person even realizing it. Appetite Regulation: Their brain is highly sensitive to "fullness" signals (leptin), causing them to naturally eat less at the next meal if they overate at the previous one.
