Tanya lost an incredible 31.1kg (4st 13lb) in 14 months

By the time teacher Tanya turned 57, she was experiencing arthritic pain, vitamin deficiencies and high blood pressure. On Christmas day 2022, she signed up to The Fast 800 Programme to turn her life around. Over the following 14 months, Tanya lost an incredible 4st 13lb (31.1kg), no longer suffers with arthritis and high blood pressure, and is now taking on a new challenge of hiking in Peru!

Where it all started

Before starting her weight-loss journey, Tanya’s physical health was at an all time low. “My whole body was in pain and everything hurt. I was also going into menopause and had put on a lot of weight. Even walking the dogs was so hard and I just couldn’t believe I was only 57 years old and I felt like I was in doom.”

After my birthday on Christmas Eve 2022, my weight was 13st 14 lb (88.9kg) and I felt like I was dying. My health wasn’t good and my blood tests showed significant vitamin deficiencies. Something had to change and there was nothing to lose, so I signed up for the online programme.

On Christmas day, Tanya threw herself into The Fast 800 Keto meal plan, on the 12-week programme, to kickstart her weight loss, and she’s never looked back.

What is The Fast 800 Programme?

Along with many other members, Tanya was surprised with how holistic the programme was, far more beyond a diet with menus and recipes. Within the 12-week course, members get full access to:

  • Plus, so much more!

The journey

After just a few weeks, Tanya started noticing results and watched as the weight fell off quickly and her eating habits began to change.

Before, food ran my life and I always wanted to eat. However, since starting the programme, I’m never hungry, and that’s why I think I was dropping weight so quickly. Once I started following the programme, my brain just switched.

Tanya found the programme invaluable for keeping on track with her new lifestyle at each stage, from following The Fast 800 Keto initially, to eventually moving to The New 5:2 and the Way of Life to maintain her weight loss.

“The programme was a game changer. Your meals are all set up for you and it’s much more motivating. It’s like having a coach that says, ‘this is what you’re eating and this is what you’ve got to buy’. I like that you can swap out recipes you don’t like too. The graph showing my weight change was also really motivating.”

Tanya’s typical day on a plate before The Fast 800

  • Breakfast: “I always ate before work, and it was often high in carbs. If I was feeling healthy, then I’d have porridge with yogurt and berries.”
  • Lunch: “I’d probably take a salad but then I’d end up grazing on all of the junk food left on the table in the staff room.”
  • Dinner: “I was usually exhausted and hungry, so it wasn’t uncommon for me to have biscuits, cheese and a few glasses of wine.”
  • Snacks: “Lots of staff room treats, and if I’d meet a friend it would always be cake and coffee.”

Tanya’s typical day on a plate now

  • Breakfast: “I have lemon water first thing in the morning. I don’t eat breakfast as I do 16:8 intermittent fasting, which fits with my lifestyle as a teacher. I usually break my fast at around 10:30am at recess with some yogurt and berries.”
  • Lunch: “I follow the principles of the programme and make a big salad with everything in it. Usually with chicken, boiled eggs and feta.”
  • Dinner: “My favourite is the Pizza Zucchini, which uses zucchini as the base with tomato paste, olives and halloumi. I also really like the Beef Bolognese with Zoodles, and Gado Gado. I like to batch cook on Sunday and freeze meals.”
  • Extras: “I use [The Fast 800] Keto Hot Chocolate with protein and collagen, Pineapple Fibre Blend which tastes really nice and has pre and probiotics, and Sleep Blend daily which is good for my sleep and cramps with all the exercise I’m doing.”

The results

Since starting her weight loss journey in December 2022, Tanya has managed to lose almost 5st [31.75kg], and has transformed her energy and physical fitness levels.

“It was a big shock even to lose a few kilos in the first month. I never dreamed I’d lose over 30kg! My life has changed in so many ways: I haven’t been this weight since I was a teenager, and regardless of the chronic injuries I’ve had along the way, I feel really healthy and fit. I don’t get that afternoon slump ever and feel energetic and have clear thinking.”

Tanya’s arthritic pain has now gone, and her new energy has led her to finding new joys in daily 5km walks, hilly 10km hikes, five-hour bike rides with her grandchildren and even 200 hours of Yoga Teacher Training.

My grandkids don’t copy my groans when they get up, and my son-in-law can’t believe it when he sees me running. My daughter has watched my successes and life changes and has started the diet as well. She is looking fantastic already!

Tanya has a new found confidence, enabling her to travel and learn new skills. She uses the yoga and pilates videos on the programme most mornings to help her combat the everyday stresses that she says she found are a “huge obstacle with losing weight and health”.

“All these fabulous things in my life are because I did The Fast 800 Keto. The programme is the best thing that I did. When your body feels good, your mind follows, and you feel more in control. Follow the science, trust the programme, prep your food, and don’t second-guess it.”
