Kirsty lost 3 stone (19kg) in just 3 months

At 35 years old, Kirsty found that she had reached a weight far heavier than she was comfortable with. She felt sluggish, lethargic and generally unhappy in herself. However, after researching different weight loss approaches, she came across The Fast 800 and everything changed. 

The Fast 800’s approach resonated with Kirsty, and having had one of Dr Michael Mosley’s books left unread on her bookshelf for several years, it felt like it was time to delve in. She was finally in the right mindset, and knew she needed to make some significant changes to her lifestyle if she wanted to become healthier. 

Kirsty devoured the information in the book and read all the online articles and resources until she decided to sign up to The Fast 800 Programme for the extra support it offered. She set a start date, and committed herself fully.

The Fast 800 Keto

Kirsty dived straight in with The Fast 800 Keto plan, which reduced her carbohydrate intake and introduced intermittent fasting. Previously used to eating processed foods and a higher carb diet, the first couple of weeks of her new lifestyle were an adjustment. However, it wasn’t long before the results made it all worth it. 

Seeing the weight fall off rapidly made the keto programme easier for Kirsty to stick to, as she became excited and motivated to continue. After a short break during the routine-disrupting school holidays, and a holiday where she began to find herself snacking again, she found out firsthand how flexible the programme is. Despite the break in her efforts, she was easily able to pick it back up again to get back on track with her weight loss journey. 

Kirsty’s weight continued to drop quickly. By the time her son returned to school after the school holidays a few weeks later, she had lost three stone and her BMI had returned to normal.

Turning her health around

Not only did Kirsty see a positive change in her weight, but her annual trip to a private health-check revealed many more benefits of her new lifestyle. The report revealed that her likelihood of developing type 2 diabetes and heart disease in the next ten years had fallen from 50% to just 0.1%. Seeing her results on paper were irrefutable: her lifestyle change really had transformed her life and future.

Embracing a healthier lifestyle benefited her wider family as well. Although they’re not following the programme, her partner and young son are also eating much more healthy foods. They all now enjoy plenty of vegetables and proteins, with less processed foods and sugar, which is simply a win win!

 I tend to have a shake as one of my meals, either breakfast, lunch or dinner, but usually for me it’s for breakfast. They were such a help to me throughout the initial stages and allow me to stick to the programme when I’m away from home.

Utilising tools for success: The Fast 800 Shakes

As well as the Programme, another tool that Kirsty found invaluable during her journey was making use of The Fast 800 Shakes. 

Early on in her journey, she was partaking in her son’s scouts camping trip and realised that the only foods available would be hotdogs, marshmallows and crisps, so she quickly stocked up on The Fast 800 Protein Shakes, which allowed her to stay on track by keeping her full and satiated. She also recently tried The Fast 800 Clear Protein and loved it.

She now frequently reaches for The Fast 800 Chocolate Shake for breakfast (or lunch or dinner if she needs to), and finds them particularly helpful for days when she’s out with her son or has a busy morning at work. The shakes allow her to stick to the programme even when she’s away from home, knowing that if she went to a supermarket she’d find it difficult to find a convenient option that would be filling, while still adhering to her keto approach.

Where is Kirsty now?

Kirsty now feels lighter, in weight and in mood. She’s much happier and much more energetic, even now that she’s relaxed her approach to the programme. She still follows the principles of The Fast 800 Keto, but has slightly increased her portion sizes to bring her more into a maintenance phase. She’s still using The Fast 800 app for delicious, healthy recipes and reads the educational articles that are featured on there. However, her new lifestyle is now not an effort and has become second nature. 

We’re thrilled that Kirsty achieved the results she was looking for when she set out on her journey.
