Jessica Simpson's smoothie diet

Jessica Simpson - who welcomed daughter Maxwell Drew into the world in May - had 60lbs to lose so to give her body the boost it needed, she followed a strict plan of consuming just healthy and nutritious smoothies for 15 days before slowly introducing snacks and meals.

She then spent five days having three smoothies a day with two healthy snacks, five days of two smoothies a day plus two healthy snacks and one meal and then five days of one smoothie a day with 2 snacks and 2 meals.

The plan, crafted by Jessica's former private chef, was part of the diet company Weight Watchers. Jessica - who is now back to her pre-pregnancy weight - signed a $4 million deal with Weight Watchers to become their spokesperson and follow their weight loss plan religiously

According to website TMZ, items on the menu included foods like egg white omelettes, chicken satay, whipped chick peas, soba noodles and shrimp skewers.
