But he didn't stop there and reassured his nearly 3 million followers that he's on his way back to his "peak." He captioned a second throwback picture, "Last throwback of the night before I go play some fat boy ball !! MOTIVATION ...HELLO??? Aw s--- what time is it man?? Do you know what time it is ?! What's going on?! You alright ? Ahh what's wrong with you? "My baby mama kissed me but she glad I'm gone, she knew me and her sister had something going on,I reach my peak, I can't speak".

Kardashian shocked fans when he gained more than 75 lbs. in less than a year. It's not clear what caused the weight gain, but it got so bad that Kris Jenner had a breakdown over his struggles on Keeping Up With The Kardashians' previous season. She confessed she spent many nights crying herself to sleep.
