EXCLUSIVE: Inside the 3556 kJ diet behind Beyonce’s 30kg weight loss

When Beyoncé hit the stage for the Grammys, it wasn't just her raunchy performance which had people talking but also her slim frame and that leg gap.

And after a bit of digging, TheFIX can exclusively reveal her new skinny shape is down to strict 3556 kilojoule diet.

Worryingly, that’s less than half of the recommended daily amount. So, what is she eating? Six teeny meals a day and of course, no carbs. Yawn!

Our insider tells us that breakfast is egg whites, with one spritz of oil, followed by elevenses of a protein bar.

Lunch is tabouli, with some hummus and fresh vegetables before an afternoon snack of a handful of kale chips.

For dinner, Bey has some steamed fish with vegetables before one spoonful of sorbet. (Not a whole spoon!)

Not a lot of energy for intense dance routines like her Grammys performance, check below.

Our source says: "Beyonce and Jay have been able to stick to their diet because they do it together. They clear out the entire kitchen, except for what is on their meal plans.

"Beyonce makes staying on the diet fun. She loves trying new recipes and experimenting with spices.

"If she's thinking about cheating, she'll go do something active. Sweating and physically exhausted, eating something unhealthy feels toxic!"

Since being on the diet, Bey, 32, has lost a shocking 30kg and is now wearing a teeny size six.

But we’re all asking….what’s so wrong with being bootylicious, Bey? Check out the slideshow below to see Bey’s body pre-diet. It looks smoking!
