Steve lost 40.5kg (6st 5lb) in 6 months

When research scientist Steve, 55, started his weight loss journey, he was feeling unhappy and uncomfortable in his body. Weighing 23.5st (148.5kg), he decided to try out The Fast 800 programme and achieved results he never thought possible. Steve lost 6.5st (40.5kg) in 6 months, and is feeling more energetic and positive than ever.

Where it all started

I was sick of being ‘big Steve’ [and] I was just not a happy person in the body I was in. It’s just uncomfortable being that big. Even simple things like sitting in an airline seat and getting in and out of the car was not easy.

Steve’s physical and mental health was very low, and he eventually reached a point where he felt a need to prove that he could set goals, stick to them and become his best self for himself and his family.

Due to work changes in 2023, he found himself ahead of a period of six months living apart from his wife and youngest daughter, and he decided to challenge himself to turn his health around.

“I was attracted to The Fast 800 programme because it’s based on science. I’m a scientist myself, so I had some knowledge of the stuff that was being spoken about and it made sense to me. I looked at all of the evidence on the website, and it really impressed me.” At that point, Steve signed up to The Very Fast 800 and committed to transforming his life.

Steve’s journey on The Very Fast 800

The Very Fast 800, one of the many approaches on The Fast 800 programme, involved Steve reducing his calorie intake to just 800 calories a day for up to 12 weeks to kickstart his weight loss. Unlike fad diets he’d tried in the past, he found the programme easy to stick to and approached it more as “an adjustment to a new healthier way to live.

Our signature, science-based 12-week Programme is now more affordable with monthly payments.

Get access to 900+ recipes, 250+ workouts and step-by-step education to help you change your life for the better.

“I can’t say I ever sort of suffered from hunger pangs or anything like that.”

“I love the recipes that are on [the programme]. I love the exercise routines, the daily workouts, and the variety of those. And through the app, it was all really easy to access, and that’s why I really liked it and why I’ve stuck with it. I love how you can set your meal plan for the following week and then a shopping list is created for you. It takes a lot of the hard work out of it and just leaves the good fun stuff to try.”

“Bending down to tie up shoelaces used to be such a chore, and balance was an issue, but that resolved itself really quickly. I felt more energetic and more inclined to do sport and go to the beach because I wasn’t self-conscious of my body shape.”

Steve’s daily diet pre-programme

Breakfast: Often skipped breakfast, or just had toast
Lunch: Leftovers from the previous night’s dinnerDinner: Lots of simple carbs like rice, pasta, and potatoes
Snacks: Habitual snacking on sweet foods, like chocolate, in the evening

Steve’s hard-earned results

Steve was surprised by the associated benefits that he experienced so quickly, like his blood pressure and heart rate which came down within weeks.

When I’ve tried anything like this in the past, it had taken at least 6 weeks before I started feeling any effect, but with The Fast 800, it was virtually immediate.

This quick change meant he could start enjoying bush walks and hikes without worrying about whether he’d manage it, and he’s found other unexpected health benefits: “donating blood is something I wouldn’t have been able to do at my previous weight and where my blood pressure was. That’s helped my mental health, feeling like I’m contributing.”

After following the 12-week programme, Steve transitioned to the Way of Life approach to keep up his hard-earned results. He finally reunited with his family 6.5st (40.5kg) lighter and they couldn’t believe the difference. “It was funny because… I didn’t tell them I was doing the programme. When I walked out of the airport they were all like, ‘my god, who is this guy?’ That was really satisfying. Everyone comments on the extra energy I have now, so it’s not just the weight loss, but the energy levels and the positive attitude as well.”
