Improve Metabolic Health

Proof required

Submit your three M1 baseline measurements: (1) waist circumference — average of two measurements with notes on technique (tape position, relaxed posture, end of exhalation); (2) resting heart rate — three consecutive morning readings and their average; (3) blood pressure — two readings and their average, with measurement source noted (pharmacy kiosk or home monitor). These are your metabolic baseline values for M3 comparison.

What gets checked

• All three metrics measured in the same week using the described technique — mismatching the measurement protocol between M1 and M3 invalidates the comparison (e.g. measuring waist with tape above the navel at M1 but at the midpoint at M3)
• Resting heart rate is the 3-day morning average, not a single reading — a single resting heart rate reading can vary by 10–20 bpm depending on sleep quality, hydration, and morning activity; the average is needed for a reliable baseline
• Blood pressure is measured seated and rested for 5 minutes before each reading — elevated readings from exercise, stress, or immediate activity inflate the baseline and make M3 comparisons misleading

Common mistakes

• Holding breath or pulling in the stomach during waist measurement — the waist circumference must be taken at relaxed exhalation; holding the measurement in reduces the reading by 2–4 cm and creates an inflation effect at M3 if relaxed measurement is used later
• Using a single-day resting heart rate measurement instead of a 3-day average — single readings are highly variable; the 3-day average is the minimum for a reliable resting heart rate baseline
• Substituting a standing blood pressure reading for a seated one — standing blood pressure readings are systematically different from seated readings; the same posture must be used at M1 and M3

Resources

What a verifier looks for

• All three metrics should be present in M1. If blood pressure is missing, ask whether the person had access to a pharmacy kiosk or home monitor — if not, waist and resting heart rate are required minimums
• Waist circumference should include a note on technique — tape position and whether the measurement was at end of exhalation. Without this, there is no way to verify that M1 and M3 used the same method
• Resting heart rate should show three individual morning readings, not just the average. If only an average is given without the underlying readings, ask for the three daily values

Proof required

Submit (1) weekly activity log for all 8 weeks showing minutes of moderate aerobic activity and strength sessions; (2) 3-day food diary from Weeks 1, 3, 5, and 7 showing the specific dietary substitutions made; (3) a brief note at each 4-week point on what specifically changed in your daily routine.

What gets checked

• Weekly activity log covers all 8 weeks with specific minutes recorded — the comparison to the 150-minute NHS target requires actual minutes, not estimated categories
• The dietary diary shows the specific substitution made each fortnight — a named change ('I replaced my daily Coke with water on weekdays') rather than a general improvement
• Both interventions are maintained across the full 8 weeks — starting strongly for 4 weeks then reverting does not constitute an 8-week programme

Common mistakes

• Counting slow walking as moderate activity — brisk walking that raises heart rate and breath rate to the point where conversation is still possible but singing is not is the NHS moderate intensity definition; slow walking does not qualify
• Focusing only on physical activity and making no dietary changes — metabolic health improvements are most durable when both activity and dietary quality change simultaneously; activity alone has limited impact on waist circumference
• Recording activity only in weeks when targets were met and omitting weeks when they were not — the 8-week log must include all weeks

Resources

What a verifier looks for

• The weekly activity log must cover all 8 weeks with specific minutes. If weeks are missing or show only categories, ask for specific minute totals
• The dietary substitutions should be specific and named. If the submission mentions 'eating healthier' without naming specific substitutions, ask what specifically changed
• Both activity and dietary interventions must be present. A log showing only activity without dietary change is missing one half of the programme

Proof required

Submit (1) M3 measurements — waist circumference (two readings and average, with technique note), resting heart rate (three consecutive morning readings and average), blood pressure (two readings and average); (2) a side-by-side comparison table showing M1 and M3 for all three metrics; (3) an attestation from a named person who observed the lifestyle changes across the 8 weeks.

What gets checked

• The same measurement technique is used at M3 as at M1 — same tape position for waist, same morning-lying-down protocol for resting heart rate, same seated-rested protocol for blood pressure
• The comparison table shows all three metrics at both M1 and M3
• The attestation describes at least one specific behavioural change observed across the 8 weeks

Common mistakes

• Measuring M3 waist late in the day — waist circumference is affected by bloating throughout the day; measure in the morning in the same conditions as M1
• Reporting M3 blood pressure from a GP or A&E setting — clinical environments systematically produce higher readings due to 'white coat effect'; use the same measurement setting as M1
• Providing an attestation from someone who only observed the final week — the attesting person should have seen the beginning and end of the 8-week programme

Resources

What a verifier looks for

• All three M3 metrics must match the M1 measurement technique. If the submission notes a different waist tape position or blood pressure setting, ask whether the difference was intentional
• The comparison table must show all three metrics at M1 and M3
• The attestation should describe observed changes, not just confirmation of programme participation
