A WOMAN dubbed the world's hottest grandmother has revealed the crazy diet she follows that she claims keeps her so fit.
Superfit Lesley Maxwell, 64, swears by fueling her body with "clean and nourishing" food to keep it in perfect shape.
The celebrity fitness coach from Melbourne, Australia, has wowed the world with her incredible physique after sharing her work outs online.
She kick-started her fitness journey in her 40s and hasn't looked back since, giving models decades her junior a run for their money.
Inevitably, Lesley is constantly bombarded with questions about how she maintains her rock-hard abs by her 119,000 Instagram followers.
The athletic gran works out five times a week, but revealed its not just her hard work in the gym that keeps her looking trim.

She credits her fitness levels to her strict diet that powers her through her incredible exercises.
Sharing a sexy snap of herself flexing her muscles in a figure-hugging yellow gym set, Lesley told her legion of followers to focus on what they are putting into their bodies.
She wrote: "I'm often asked when is the best time to train and my answer may surprise you.
"For me, as long as I have eaten properly... then I have energy to train. I always make sure I fuel my body with enough protein and fats."

The stunning gran, who is often mistaken for her 20-year-old granddaughter, also shared the bizarre ingredients of a concoction she guzzles each day on the go.
Lesley continued: "My favourite quick shake contains Collage Protein Power, goats yoghurt and a raw egg yolk which I have when I'm on the run.
"Usually, I eat protein and fats every two to three hours. No fasting for me."
She went on to recommend chowing down on the likes of porterhouse steak and whole eggs to stay fighting fit.
Despite trolls slamming her workout regimens, Lesley refuses to let the negativity bring her down.
One hater hit out at the gran, claiming her exercises were "easy peasy" and that they could do her pull-ups "with my pinky".
Another branded her latest vid "a good warm-up", belittling her efforts in the gym.
But the fitness guru brushes off any cyberbullying by simply uploading another post showing off her extraordinary abs.
The influencer regularly shares sexy snaps posing in teeny bikinis on social media to inspire others to embark on their own fitness journey.
Lesley believes you are "never too old to wear" revealing swimsuits and that exercise helps "reverse the aging process".
She says eating clean and working out also makes her stay confident in her love life - with the cougar confessing she is currently dating a younger man.
The glam gran added: "The man I’m seeing is younger than me but I never think about that. Confidence is a win for me.
"If a man is brave enough to walk straight up to me and stare me in the eyes and ask me out, he’s a pretty brave man.
