Sensible and sustainable
A sustainable approach to nutrition rather than a restrictive crash diet you abandon within a fortnight.
Eat and live in a way that actually changes your body, built around a demanding week.
Eat and live in a way that actually changes your body composition, with sustainable nutrition and lifestyle support at UNTIL Liverpool Street, London, backed by a Precision Nutrition Level 1 certification.
The short answer
Nutrition and lifestyle support with Jasper MacDermot is sensible, sustainable guidance at UNTIL Liverpool Street, backed by a Precision Nutrition Level 1 certification, that covers how you eat for body composition, how you fuel your training, and the sleep, stress, and routine that quietly decide your results. Training builds the stimulus, and nutrition and lifestyle decide how much of it you keep: this is the part that turns good sessions into a body that looks, feels, and performs the way you want.
Jasper coaches this alongside your training, not as a separate plan to ignore. The approach is sensible and sustainable, built around your real life rather than a crash diet you abandon in a fortnight, because the habits that last are the ones that actually change your shape. It is guidance you can hold around a demanding schedule.
It starts with how you actually eat and live now, not an idealised version, then builds a small number of sustainable habits matched to your goal, whether that is fat loss, lean gain, or simply eating to support hard training. This is general nutrition coaching for healthy adults, not clinical dietetics: a medical condition, an eating-disorder history, or a complex dietary need is referred to a registered dietitian or your GP.

Jasper starts with how you actually eat and live now, not an idealised version. Your typical week, your schedule, your sleep, and your relationship with food all shape the plan, so the guidance fits your real life rather than fighting it.
Rather than a rigid meal plan to follow perfectly or fail, you build a small number of sustainable habits that move your nutrition in the right direction, matched to your goal, whether that is fat loss, lean gain, or fuelling hard training.
Your body composition is reviewed over weeks as the real marker, not daily scale weight. As your training and life change, the guidance is adjusted, so the nutrition keeps working with the programme rather than drifting out of step.

FAQ
No. Jasper, a Precision Nutrition Level 1 coach, favours sustainable habits over rigid meal plans or crash diets. The aim is guidance you can actually live with around a busy schedule, because the eating patterns that last are the ones that change your body composition for good, not the ones you abandon within a fortnight.
No. This is general nutrition and lifestyle coaching for healthy adults pursuing fitness and body-composition goals, not medical or clinical dietetics. If you have a medical condition, an eating-disorder history, or a complex dietary requirement, Jasper will recommend you work with a registered dietitian or your GP rather than offering advice outside his scope.
Nutrition and lifestyle support works best alongside training, because the two are designed to pull in the same direction. It is usually folded into 1-2-1 or online coaching rather than sold as a standalone plan. If you are unsure what fits, get in touch and Jasper will talk through the right combination for your goal.
Meaningful changes in body composition are realistic over a twelve-week block of consistent training and nutrition, which is the minimum commitment for the coaching. The exact pace depends on your starting point and consistency. The focus stays on a sustainable rate you can hold beyond the programme, rather than a fast result that does not last.
