Now the rising junior from England has been on coach Raphael Chillious' three-plate-a-meal "diet" and is now 6-9 and 215 pounds.
``He was skinny," said teammate Justin Robertson, a fellow London native who has known Amaning since he was about 10.
The added weight isn't the only change in his game. He's also much more comfortable nearly a year removed from coming over from London.
``There's been a huge difference in my game," Amaning said. "Before I was more of a 1-on-1 streetball player. Now I know how to play basketball."
"He plays different now," Robertson added. "He plays with more anger and aggression."
Amaning will go from a supporting guy who averaged about a half-dozen points per game a year ago to one who should turn into one of the leaders – both on and off the court – for Chillious this season.
``He's going to be put in a position where he can succeed," Chillious said. "It's going to be up to him, though."
Amaning will still need to work on his lateral quickness in order to be able to play on the wing, but his body will likely mean he plays more at the power forward spot in college.
``He's a combo forward," Chillious said. "But when he decides to use his jump hook, he can be a five."
While Amaning listens to his new teammate, Serbian Dragoslav Papic, and his intentions to go directly to the NBA after spending two seasons at South Kent, Amaning has no illusions.
College is the priority for Amaning – although he's still in the early stages of which schools he likes.
``I'm really not thinking about it right now," Amaning said. "But when I do, I want to go somewhere that's the best fit for me."
