Kate Middleton came across as somewhat thin to some who saw our new video of her from this past weekend — but she’s got one fitness guru in her corner … one Jillian Michaels.

On the subject of speculating on Kate — be it her health, her weight or anything else — Jillian tells us folks need to piss off and leave her alone … ’cause it’s not their business.

She reminds us someone’s health journey is very personal — and considering the type of microscope Kate’s been under lately … Jillian says everyone needs perspective.

Sage advice from Jillian — but something tells us the public will continue picking apart every little detail. Remember, prior to the video TMZ published Monday … we hadn’t seen her on her own two feet since December, which is quite a long time.

Of course, she underwent abdominal surgery — for a condition that hasn’t been made public — and Kensington Palace said she wouldn’t be resuming her duties until at least after Easter.
