Jessica Simpson has battled with her weight for years but after giving birth to daughter Maxwell in May, she vowed to lose weight.

And now after sticking to a strict diet for four months, Jessica Simpson’s success is clear to see.

According to TMZ, Jessica Simpson, 32, has lost a staggering 60 pounds on a healthy eating plan filled with low-fat smoothies, protein and plenty of vegetables.

The nutritious plan, obtained by TMZ, was devised by her former private chef and adheres to the WeightWatchers point system where each food has a “points value” based on calories and fat content.

The plan, featuring dishes such as super low calorie egg white omelettes, chicken satays, whipped chick peas, soba noodles and shrimp skewers, has clearly worked wonders.

Jessica Simpson’s diet began in July with a 15-day smoothie diet consisting of five days of three smoothies a day, gradually working in snacks and meals over time.

She was spotted showcasing her trim new figure whilst helping her younger sister Ashlee promote her new clothing line in Tampa, Florida last week.

Jessica Simpson recently starred in a WeightWatchers commercial saying: “There is a lot of pressure to lose weight but I’m not a supermodel.

“I’m just Jessica trying to eat real food in the real world and I really just want to be healthy for my daughter so I knew WeightWatchers was the only way to go.

“It’s working, I’m on my way and it feels amazing. Really I just want to be a better version of myself.”
