Because they have evolved a nutritional strategy that means that they can survive by eating most of whole carcasses - they do not just eat muscle, which is what your question may be implying.
Lions are strictly carnivores (meat eaters).

No. Lions are carnivors so they eat meat, not omnivours who eat meat and veg. Lions are big because of the amount of meat of other animals they eat. You don't see lions eating bananas, do you?
While lions are primarily carnivorous and rely heavily on meat, they may occasionally consume other items out of necessity. They have been observed eating grass or plants, which may aid in digestion or help purge their systems. Additionally, lions might ingest fruits or berries when prey is scarce, although these are not a significant part of their diet. Overall, meat remains their main source of nutrition.
Animals which feed on other animals i.e., purely eating their raw flesh are called carnivores.
Lions can move. It'd be quite difficult for a meat-eating, predatory animal to survive without being able to move.
'Carnivorous' animals are those that eat meat.
Some common meat-eating animals include lions, tigers, wolves, and crocodiles.
Carnivores are the animals that eat only meats, like lions. Omnivores are animals that eat both plants and animals, like humans. I hope that is the answer you were looking for, as apposed to you wanting someone to name every meat eating animal on the planet, because that won't happen.
The lion has a rough tongue, and use it to rasp meat off the bone when eating.
Lions do not typically eat grass as a primary food source. However, some lions have been observed chewing on grass, which can help with digestion or induce vomiting to expel unwanted materials from their stomachs.
Both carnivores and omnivores eat meat. Omnivores also eat plants.
