Caytra
The Caytra Metabolic Health Programme

Six months to improve your metabolic health and become measurably stronger.

A private programme for women experiencing changes in body composition, strength and health-screening results during the menopause transition. Caytra brings nutrition, training and recovery into one plan, while incorporating and coordinating appropriate clinical input where it is needed.

Speak with Caytra

Start with a private conversation. We’ll tell you honestly whether the programme is appropriate for you.

You know the basics. But the basics are no longer producing the same result.

Your waist or your weight has changed. A screening result, perhaps glucose, cholesterol or blood pressure, is moving in the wrong direction. You may feel weaker, recover differently or sleep less reliably than you used to.

You may already have a doctor, a personal trainer, a wearable and a reasonable understanding of healthy eating. Each gives you one part of the answer.

The real question is what has changed, what needs medical attention and which few actions will move the outcomes that matter.

You do not need more disconnected advice. You need one properly constructed programme.

What we work to change

Three connected areas. One programme.

Metabolic health

Relevant measures such as glucose, cholesterol, blood pressure or liver markers, selected and clinically managed with the appropriate practitioner.

Body composition and muscle

Changes in waist, weight and body composition considered alongside muscle, nutrition and the way the body is responding to training.

Strength, capacity and bone health

Progressive training designed to improve measurable strength and physical capacity while supporting muscle and long-term bone health.

These outcomes are connected. Muscle influences how the body uses energy and responds to glucose. Nutrition and progressive resistance training affect body composition, strength and long-term bone health. Sleep, recovery, hormones and medical factors can influence all of them. The programme considers them together rather than treating weight, exercise or nutrition as separate problems.

Measures are selected individually. Caytra does not promise a particular medical or physical result, but the programme is accountable for setting a clear baseline, monitoring progress and changing direction when necessary.

Who the programme is for

Designed for a specific kind of change

The programme tends to fit best when several of these are happening together.

  • Your waist or body composition has changed despite broadly healthy habits.
  • Your glucose, cholesterol, blood pressure or related markers are drifting.
  • You feel less strong, or you recover less reliably.
  • Perimenopause or menopause may be affecting the wider picture.
  • You are using or considering medical treatment and want nutrition and training handled properly alongside it.
  • You want nutrition, strength, recovery and the medical context brought together, not another programme focused on only one of them.

This programme is designed for women whose needs cross several areas. If what you need is only a meal plan, personal training or an answer to one clinical question, a focused practitioner is likely to be the better fit. Medical conditions requiring diagnosis or treatment remain with the appropriate clinician.

How the programme works

Five stages across six months.

01 · Build your metabolic picture

We review your relevant health results, medical history, medication, symptoms, sleep, nutrition, training, changes in body composition and muscle, and the real constraints of your week, then identify what belongs in the programme and what needs clinical clarification.

02 · Agree the outcomes that matter

We agree a small number of measurable priorities across metabolic health, body composition, muscle, strength and physical capacity, then put them in writing.

03 · Put one plan into practice

Nutrition, strength, recovery and behavioural coaching come together in one programme led by Arun. Where you already have clinicians or practitioners, their input is incorporated when relevant. Training is built to support muscle alongside measurable strength.

04 · Measure, adapt and keep it moving

Your Relationship Manager checks in formally each week, and Arun conducts a comprehensive review each month. During that review, Arun considers what has changed, what has been completed, what is not working, what the measurements show, what other practitioners have advised and where gaps remain. Together, you decide what to continue, what to change, what needs clarification and what should go back to another practitioner, then set the priorities for the next month.

The purpose is to shorten the time between trying something, learning from it and improving the plan. Instead of continuing for months with an approach that is impractical or producing little progress, the programme identifies friction early and changes direction. We also reassess formally at the midpoint.

05 · Finish with a plan that continues

The six months end with final measures, a review of what changed and a clear twelve-month continuation plan.

How measurement is scheduled
At the start
Metabolic review, relevant baseline measures and a written programme
First month
Nutrition, strength and recovery plan put into practice
Every month
Comprehensive progress review with Arun, and programme adjustment
At the midpoint
Selected measures repeated and the direction reconsidered
At six months
Final review, relevant repeat measures and a twelve-month continuation plan

Measures are chosen for you rather than applied as a standard panel. Where clinical testing would be useful, it is discussed with and arranged through the appropriate licensed provider, and paid for separately.

One accountable team

One team. One plan. One place that knows what is happening.

The programme is personally led by Dr Arun Jayaraj, who leads the nutrition, strength, recovery and behavioural work. Additional professional expertise is brought in where it would improve the plan. Your Relationship Manager stays close to the day-to-day work and keeps the whole programme moving.

Who you work with
Dr Arun Jayaraj
Health Adviser and Programme Lead
Arun establishes the priorities, constructs the programme and leads its implementation across the six months. He brings together the medical context, nutrition, strength, recovery and the practical realities of your life. He conducts a comprehensive monthly progress review and remains available through Caytra when questions requiring his judgement arise between reviews.
Relationship Manager
Your day-to-day programme lead
Your Relationship Manager stays closest to the programme from week to week. She conducts a formal weekly check-in, helps turn decisions into practical next steps, notices when something is slipping and follows through until the agreed next step is completed.
Additional practitioners
Doctors, personal trainers, nutrition professionals, physiotherapists and other specialists may be brought into the plan when their expertise is useful. Their fees are separate from the Caytra programme, and they remain responsible for the services they provide.
How support works
Every week
One formal check-in with your Relationship Manager
Between check-ins
Ongoing WhatsApp support from Caytra
Every month
One comprehensive progress review with Arun

You can message Caytra between formal check-ins when a question, difficulty or change arises.

Bringing in other practitioners

When another practitioner would help, Caytra researches realistic options and explains what each professional would contribute, how the service works, likely fees and relevant practical considerations. You decide whether to proceed and pay the practitioner directly.

Once someone is involved, Caytra incorporates their recommendations into the wider programme and, with your consent, keeps the appropriate people updated. You should not have to transfer every piece of information or work out how different recommendations fit together yourself.

What it looks like

Two illustrative examples of how the programme can be constructed around different starting points.

On a GLP-1, with cholesterol rising and perimenopause in the picture

What had changed

She had started a GLP-1 with her doctor and was responding well. Her cholesterol was elevated and perimenopause was adding another layer. She wanted the nutrition, strength and recovery around her treatment handled properly.

She already had a GP and a personal trainer. Nobody was looking across all of it.

What needed clarification

Her protein intake was low and her appetite was lowest in the days after each dose, which raised the question of whether she was losing muscle alongside fat. Her training had not changed since she started the medication, the relevant markers had not been reassessed since these changes began, and her sleep was short and variable.

Which of those belonged with her doctor and which belonged in the programme had to be separated before anything was changed.

What the programme prioritised
01A practical way of eating around the medication.Protein brought up gradually across the week, with simple options for the days when appetite was lowest. A way of eating she could keep up afterwards, not a temporary diet.
02Strength training as the priority in her week.Her programme was built around protecting muscle while her weight was changing, and progressed with her personal trainer working from the same plan.
03Sleep and recovery before adding anything more.Few changes at a time, using her own wearable data to see whether they were helping.
What was measured

Waist measurement and body composition at the start, midpoint and end. Selected strength and capacity measures on the same schedule. Updated bloodwork arranged through a participating provider and reviewed by her doctor, who remained responsible for her medication.

How the plan adapted

As her appetite settled, the eating strategy changed with it and the strength work progressed. At the midpoint, the repeat measures set the direction for the second half. The six months ended with a final review and a twelve-month continuation plan she could continue with her own doctor and personal trainer.

A changing waist, a screening result drifting and less reliable recovery

What had changed

Her waist had changed over two years without much change in her weight. A recent screening had shown glucose and cholesterol moving in the wrong direction. She wanted to understand what could be improved through the programme while discussing the screening results appropriately with her doctor.

She also felt weaker than she used to, and found she needed longer between harder sessions. Her habits were broadly good, which was the confusing part.

What needed clarification

Whether the screening results needed clinical follow-up, and on what timeframe, was a question for her doctor rather than for us. We set out what we had seen, what we thought needed a clinical view and what the programme would work on in the meantime.

Her training was largely cardiovascular, with little progressive loading, and her eating was light through the day and heavier in the evening around work.

What the programme prioritised
01Progressive strength work twice a week.Built for muscle and capacity rather than calorie burn, with hotel and home versions for travel weeks.
02Eating rebalanced across the day.Protein and fibre brought forward, and a workable approach to client dinners and restaurant meals rather than an instruction to avoid them.
03Recovery treated as part of the programme.Training load matched to sleep and travel, so the harder weeks were the ones she could absorb.
What was measured

Waist measurement and body composition, strength and capacity measures tied to what she wanted to be able to do, and repeat screening arranged through her own doctor on the timeframe agreed with her doctor.

How the plan adapted

A month of heavy travel was planned for rather than written off. At the midpoint the measures were repeated and the balance between strength and conditioning changed. The programme finished with a final review, her repeat results read alongside everything else that had changed, and a twelve-month plan.
