Britney Spears says she has never been healthier.

The ‘Toxic’ singer, who recently showed off her toned body in a skimpy
bikini while on holiday in Mexico, revealed her fantastic new figure is down
to a strict high-protein diet.

She told OK! magazine: "I'm the healthiest I've been all my life.

My diet has a lot to do with my getting into shape. I have no sugar. I don't
eat fruit or even fruit juice because of the sugar. I eat chicken and salmon
and rice. I eat avocados. I'll have egg whites for breakfast and sometimes
turkey burgers for lunch.

“I try to do just 1,200 calories a day. It may sound like it's not much, but
it's actually a lot of food if you eat the right things."

Britney has also embarked on a new exercise regime and has been doing “lots
of cardio and weights” five times a week.

Meanwhile, it has been claimed the 26-year-old singer is going to try to
regain full custody of her two sons, Sean Preston, two and 23-month-old
Jayden James.

Britney is believed to have visited celebrity lawyer Barry Tarlow’s office
with her mother Lynne on Tuesday.

She is reportedly determined to get her sons back in the next six to nine
months.

Britney currently has two visits and one overnight stay with her children,
while her ex-husband Kevin Federline has primary custody.

A hearing has been scheduled for September 16.
