Kim Kardashian’s personal trainer maintains the reality star lost 16 pounds in three weeks the “healthy way.”

“I think one of the misconceptions is — she works really hard. I was there through the process and it wasn’t like a starving yourself type of thing,” Don-A-Matrix told TMZ.

“She’s been on a real balanced diet and at times she wouldn’t eat as much, but then the second thing was she went to the gym and put the work in.”

Don-A-Matrix, who also has worked with Khloé Kardashian over the years, maintained that the Skims founder was “sometimes” working out “twice a day.”

“It’s possible to lose 20 pounds in a healthy way,” he added, providing no specific timeline.

Kardashian, 41, came under fire for admitting she followed a “strict” diet for three weeks in order to fit into Marilyn Monroe’s iconic dress for the Met Gala.

“To walk on a red carpet and do an interview where you say how starving you are… because you haven’t eaten carbs in the last month…all to fit in a f–king dress?” “Riverdale” star Lili Reinhart, 25, wrote on her Instagram Story Tuesday. “So wrong. So f–ked on 100s of levels.”
