High-performing women across the UK are increasingly turning to a new approach to fat loss that requires no calorie counting, restrictive food rules or dieting — with a fresh round of the programme scheduled to begin in January 2026.
The SMART RESET™, created by multi award-winning Eating Behaviour Expert Hanna Longstaff, is a structured 21-day programme created specifically for busy, career-driven women who want results without complex nutrition plans or willpower battles.
To preserve the supportive nature of the experience, the next programme cycle will be limited to 30 places.
Hanna developed the framework after resolving over 35 years of personal struggles with binge eating and dieting. With more than 12 years’ training across nutrition, behavioural psychology and metabolism, she discovered one key biological principle: a single hormone dictates whether fat is stored or burned. Through timing and structure rather than restriction, the programme teaches women how to regulate it.
So far, the programme has supported hundreds of women — from senior leaders and founders to working parents — helping them experience reduced cravings, better sleep, heightened energy, improved hormones and consistent fat loss. Many report the most significant change is finally feeling in control around food.
One recent participant shared: “Not only have I lost weight, but mentally and emotionally I feel so much better about myself. It was simple and it worked; I noticed the change almost instantly.”
A major feature of the programme is its adaptability. Every participant receives a personalised structure that fits around real life — travel, hybrid working, childcare, leadership roles and shifting schedules.
Hanna believes The SMART RESET™ provides a long-awaited alternative to the diet cycle. She said: “You don’t need more willpower, you need the right system. When you understand how to regulate this hormone by following this system, everything becomes easier, and you feel so much better. You can eat more without any bloating, feel satisfied and still see your body change.”
With more women prioritising sustainability over strict dieting, The SMART RESET™ is gaining recognition as a behavioural and biological solution that transforms both habits and confidence.
