A 53‑year‑old woman from the UK lost six stone—84 pounds—by following Dr. Michael Mosley’s Fast 800 diet after a trip to the Greek island of Symi in June 2024. Inspired by Mosley’s recent death, she committed to a very low‑calorie Mediterranean plan, paired with home‑based HIIT and resistance training, and reached her goal weight of eight stone by summer 2025.

June 2024 : A Greek vacation sparked a health turning point

While vacationing on Symi, the woman realized she could barely walk up a hill,a stark contrast to her lifelong struggle with emotional eating that had pushed her to 14 stone 7 lb (≈ 202 lb). The trip coincided with the news of Dr. michael Mosley’s death, a figure she followed through his podcasts. "I felt a deep connection to him and wanted his legacy to affect me," she recalled, prompting her enrollment in the Fast 800 program.

The Very Fast 800 regimen delivered a stone in 12 weeks

According to the report, she signed up for the Very Fast 800 plan, which restricts daily intake to 800‑900 calories across two to three Mediterranean‑style meals for a 12‑week period. She adhered strictly to the diet and performed the app‑prescribed HIIT and resistance workouts five days a week. By the end of the phase, she had lost one stone (≈ 14 lb) and transitioned to the New 5:2 plan, eating 800 calories only two days a week thereafter.

One year later: reaching eight stone and reversing health issues

By summer 2025, the woman hit her target weight of eight stone (≈ 112 lb) and a size 8 clothing label, a full 84‑pound drop from her peak. She also reported that IBS symptoms vanished within three days of starting the diet, borderline diabetes resolved within a year, and menopausal hot flushes disappeared after a few months. She attributes the IBS relief to eliminating artificial sweeteners, which re‑triggered symptoms when re‑introduced.

Daily routine now centers on Mediterranean foods and varied exercise

The Fast 800 app’s recipes and shopping lists helped her adopt vegetables she once disliked, such as broccoli,kale, and chickpeas. Her typical day now includes Greek yogurt with fruit for breakfast, chickpea curry or broccoli soup for lunch, and herb‑crusted fish or beef hotpot for dinner. Exercise has evolved from beginner HIIT to advanced sessions , plus yoga and sea swimming five mornings a week, making a 15‑minute steep beach walk effortless.

Who remains silent? Gaps in the evidence

While the personal account is compelling, the source does not provide independent medical verification of the claimed reversal of diabetes or the long‑term sustainability of a sub‑1000‑calorie diet. It also lacks comparative data on how many Fast 800 participants achieve similar results, leaving open questions about broader efficacy.

According to the report, the woman’s transformation also reshaped her lifestyle: she now works part‑time in local government, pursues fine‑art photography, and focuses on life goals beyond the scale. Her story underscores the psychological shift from weight‑centric goals to holistic well‑being.
