Programmes
At BTX, nutrition isn’t an add on. It’s half the programme. Because you cannot out train a poor diet, and you cannot achieve your best body composition without fuelling it correctly.
The BTX method
BTX nutrition coaching is evidence based, individualised, and built around your life, not some idealised lifestyle that doesn’t exist for you. We don’t give you a meal plan and expect you to follow it perfectly. We build habits, understanding, and flexibility so that nutrition becomes a sustainable part of who you are.
Every nutrition protocol at BTX starts with data. We use InBody 770 body composition scanning to establish your baseline, understanding your muscle mass, fat mass, and metabolic rate before prescribing anything. We rescan every 4 to 6 weeks to track what’s working and adjust accordingly.

Why BTX?
Lasting change needs a programme, not drop in workouts. Everything at BTX is built around your data, your schedule and a coach who is with you for every rep.
How it works
15 minutes with a BTX coach to talk through your training history, health, goals and schedule. No sales pressure.
Your InBody 770 scan measures body fat, skeletal muscle and metabolic rate, alongside a full movement assessment.
Periodised training and realistic nutrition, with a rescan every 4 weeks, so progress is measured, not guessed.

Training at BTX is priced as a membership, not per session, because lasting results need a programme rather than drop in workouts. We match the plan to your goals on your free strategy call. Most clients train 2 to 4 sessions a week.
Most clients see measurable changes in body composition within 4 to 6 weeks of following their programme consistently. We check it with an InBody 770 rescan every 4 weeks.
No. We don’t prescribe restrictive meal plans. Your nutrition is built around your lifestyle, food preferences and schedule, so it lasts beyond the 12 weeks.
We regularly work with clients managing type 2 diabetes, hypothyroidism, osteoporosis, high blood pressure and recovery after surgery, following NHS physical activity guidance. We liaise with your GP or specialist where appropriate.
