Restriction leads to another restart
Cutting food harder may create short-term progress, but it often increases hunger, guilt and the urge to overeat when the routine slips.
Personalised one-to-one online coaching for women
Lose weight with a plan built around your life.
SUSTAIN helps women lose weight, improve their relationship with food and build habits they can maintain, through a customised meal strategy, a personalised workout plan, regular progress check-ins and ongoing one-to-one support from Oli.

Why you keep ending up back at the start
Many women who join SUSTAIN have already tried slimming clubs, restrictive diets, generic meal plans or weight-loss medication. Weight may come down at first, but the underlying eating habits, emotional triggers and routines often stay the same. When life gets busy, the same yo-yo cycle starts again.

Cutting food harder may create short-term progress, but it often increases hunger, guilt and the urge to overeat when the routine slips.
02
A generic plan cannot account for your work, family, food preferences, emotional triggers or the way you currently live.
03
When motivation drops, most plans leave you alone with the same decisions and habits that were difficult before.
You probably do not need more willpower. You need structure, accountability and an approach designed around you.
The SUSTAIN approach
No more guessing, no more starting from scratch every Monday. Three phases that take you from where you are now to habits you can keep for good.
Phase one
Oli reviews your eating patterns, routines, emotional triggers, previous attempts, lifestyle and current ability. This shows what actually needs to change, instead of assuming you need another stricter diet.
Phase two
Your customised meal strategy, workout plan and goals are shaped around your starting point, preferences and schedule. The approach has to work during normal weeks, not only when life is quiet.
Phase three
Regular check-ins and progress data show what is working and what needs to change. You also learn how to handle weekends, meals out, holidays, emotional eating and low motivation without abandoning the process.
Personalised support at every stage
Your plan, your check-ins and your coach, all in one simple app on your phone.

A personalised approach to meals and nutrition built around your weight-loss goal, preferences, routine and relationship with food.

Tailored training suited to your goals, current ability, available equipment, schedule and confidence.

Structured reviews that pick out your wins, spot problems early and set the next priority.

Changes based on your progress, adherence and real feedback, rather than guesswork or panic.

Ongoing access to guidance when a difficult week, a setback or a tricky decision could otherwise knock you off track.

Support with emotional eating, all-or-nothing thinking, confidence and the routines that need to last beyond the programme.






Coaching without judgment
Oli works with women at every starting point, including women beginning at 18 or 20 stone who may feel embarrassed, judged or unsure where to start. SUSTAIN gives you a private, supportive space without lowering the standard of commitment it takes to change.

Your coach
I'm Oli McCann, and I created SUSTAIN for women who feel stuck with their weight and their relationship with food.
Many of the women I coach have spent years feeling as though they have failed every plan they tried. My job is to understand what is really happening, make the process clear and give you the support and accountability you need to change it.
I will not judge your starting point or tell you what you want to hear. I will give you an honest plan, clear feedback and a high standard of support, but you must be prepared to do the work.
