Emma Thompson drops two sizes in six weeksLondon, Jan 5 (AZINS) Actress Emma Thompson has dropped two sizes in six weeks with the help from Duchess of Cambridge Kate Middleton's personal trainer and dietician Louise Parker.

The actress even penned the forward to Parker's new book "The Louise Parker Method: Lean For Life: The Cookbook".

"Louise is the only one out there I trust. I love that her method is not a diet, and is genuinely sustainable. So, I can have my glass of wine and manage to avoid spending the rest of the week eating cheesy Wotsits," Thompson wrote.

Thompson says she has dropped two dress sizes, going down to a six from a 10, in only six weeks, reports eonline.com.

"She toughens me up without driving me round the bend with kale juice and the more depressing style of sprout," Thompson continued.

"She just gets it. We all use her, because she's discreet and funny and that's really important."

The 57-year-old signed up for The Method, which costs about $5,500 and includes an intensive weight loss course as well as a bespoke diet plan.
