I am glad he can do it, unlike that one guy from the Pelicans.
Kidding. I think this change is a sign that he will be pursuing that championship again, and with weight loss, he can move faster and probably jump higher now. Even Draymond Green has something to say about it.
It’s manageable for Luka to this since he is not that fat and huge frame body. He is this same skinny when he is a rookie so this is expected once he is motivated especially that he was traded due to being fat already.
Unlike Zion, He is a natural huge frame which his body needs food in able to maintain that massive body. I think what he needs is a proper diet rather than eating unli burritos and burger.
