No planet gives fat. Fat is a type of nutrient that is found in food, not on planets.
The concept of planets giving fat is a misconception. Planets are celestial bodies that orbit stars. They are made up of different elements and compounds, but they do not contain or produce fat.
Fat is a type of lipid, which is an essential nutrient that provides energy and helps our bodies function properly. We get fat from the food we eat, such as meat, dairy products, and oils.
