In this solo YouTube explanation, Eric Roberts clarifies how the body disposes of fat during weight loss. He debunks common myths that fat leaves the body primarily through sweat or urine, explaining instead that roughly 85% of the mass of lost fat is converted to carbon dioxide and expelled via the lungs. He notes that this metabolic process can cause a metallic or odd taste, texture, or smell in the breath, which he attributes to the by‑product of fat oxidation. Finally, he mentions that the fat being metabolized is mobilized from the stomach area, linking the biochemical pathway to the physical location of stored fat.

Do you know how your body burns fat and what it does with the fat when you burn it? Most people guess you might sweat it out, pee it out. All of those are mostly wrong because for every 10 pounds of fat that you lose, 8.5 pounds leaves your body as carbon dioxide, AKA you breathe it out. This is why if your breath has been a little raunchy, almost has like a metallic slightly weird taste, texture, or smell to it, that's the byproduct of fat leaving your body, and eventually, that fat will be pulled from your stomach.
