How it works
From a number on a lab report
to a daily action plan.
Cholesterol is shaped by hundreds of daily decisions - what you eat, how much you move, how well you sleep, whether you take your statin. Ziva tracks all of them between lab tests and shows Isabella exactly what's driving your numbers.
1
Submit your lab results
Enter your lipid panel - LDL-C, HDL-C, triglycerides, total cholesterol, and ApoB if available. Isabella plots your trend over time, contextualises each value, and shows what's changed since your last test.
2
Log your daily diet — you enter this
Nutrition logging tracks saturated fat, soluble fibre, omega-3, and dietary cholesterol daily - the four dietary levers with the most evidence for lipid improvement. Isabella shows your weekly averages and whether you're hitting targets.
3
Connect your wearable (optional)
Apple Watch or Oura adds daily steps, exercise minutes, Zone 2 time, sleep duration, and HRV - all of which independently affect your lipid profile. Isabella tracks your weekly exercise minutes toward the 150-min threshold that improves HDL and triglycerides.
4
Track your statin (if prescribed)
Daily statin and medication adherence tracked with timestamped logs. Isabella correlates adherence with your LDL trend - so your provider can see exactly what changed between tests.
5
Monthly report shared with your provider
Lab trends, dietary averages, medication adherence, exercise minutes, sleep quality, and Isabella's analysis - ready before every appointment. Supports RTM billing.

"Saturated fat is well controlled at 11g/day — below the 15g target. Your soluble fibre is the remaining gap: averaging 6g when the evidence-based target for LDL reduction is 10–15g. Adding oats, psyllium, or legumes daily would meaningfully accelerate your next LDL reading. Sleep is also short — 19 nights above 7 hours leaves room to improve HDL further."
Diet & nutrition
Saturated fat is the
lever most people miss.
The average Western diet contains 30–35g of saturated fat per day - more than double the evidence-based target for LDL reduction. Most of it is hidden in cheese, processed meats, baked goods, and full-fat dairy. Isabella's nutrition logging tracks your daily saturated fat, soluble fibre, and omega-3 - the three dietary factors with the most impact on your lipid panel.
✓Saturated fat target: <15g/day reduces LDL by 5–15% in most people — replacing sat fat with unsaturated fat (olive oil, nuts, avocado) is more effective than simply reducing fat overall
✓Soluble fibre target: 10–15g/day (oats, psyllium, legumes, apples) binds bile acids and reduces LDL reabsorption — lowers LDL by 5–10% with consistent intake
✓Omega-3 (EPA+DHA): 2–4g/day from oily fish or supplements reduces triglycerides by 20–30% — the most powerful single dietary intervention for high triglycerides
✓Plant sterols 2g/day (fortified foods or supplements) reduce LDL by 8–10% — additive with statin therapy
✓Reduce refined carbohydrates and added sugar — white bread, white rice, pastries, and sugary drinks drive triglyceride synthesis in the liver and promote small, dense LDL particles (more atherogenic than large LDL at the same LDL-C reading). Replacing refined carbs with whole grains, legumes, and vegetables improves both triglycerides and LDL particle quality
✓Eliminate trans fats (partially hydrogenated oils in processed foods) — directly raises LDL and lowers HDL; no safe intake level

Isabella · Dietary insight
"Saturated fat is on target. Your soluble fibre is the gap — at 6g/day you're getting about half the therapeutic dose. Adding a tablespoon of psyllium husk to breakfast and a daily portion of lentils or oats would bring you to the 10–15g range where the LDL benefit becomes clinically meaningful."

Isabella · 90-day attribution
"Your LDL dropped 48 points in 6 months. The main drivers: statin at 97% adherence (estimated −35 mg/dL), saturated fat reduction from 22g to 11g/day (estimated −12 mg/dL), and weight loss of 3.2kg (estimated −8 mg/dL). Exercise raised HDL from 48 to 58. Sleep is the remaining lever — improving from 19 to 24+ nights above 7h would further improve both HDL and triglycerides."
Exercise, sleep & weight
Three lifestyle levers
that move different markers.
Diet controls LDL - but exercise, sleep, and weight each target different parts of the lipid panel. Exercise is the most reliable way to raise HDL and reduce triglycerides. Sleep deprivation raises LDL through cortisol-driven hepatic synthesis. Weight loss reduces all markers, particularly triglycerides and small, dense LDL particles. Isabella tracks all three and shows which is moving which marker.
✓Exercise: 150+ min/week of aerobic activity raises HDL by 3–5 mg/dL and reduces triglycerides by 10–20% — tracked automatically from your wearable
✓Sleep: people sleeping <6h have significantly higher LDL and lower HDL — improving sleep quality is a measurable lipid intervention tracked via HRV and sleep duration
✓Weight: every 5kg of weight loss reduces triglycerides by 10–20 mg/dL and shifts LDL particles from small/dense to large/buoyant — less atherogenic at the same LDL-C level
✓Alcohol: raises triglycerides dose-dependently — each week above 14 units meaningfully elevates fasting triglycerides. Tracked in Ziva's alcohol log
✓Smoking cessation raises HDL by 5–10 mg/dL within weeks — the fastest single modifiable intervention for HDL improvement
How Ziva helps
Cholesterol improves in
the gaps between blood tests.
A lipid panel every 3 months tells you the result - Ziva tells you why it changed. Isabella tracks every daily input that determines your numbers and connects them to your labs so nothing is invisible.

Isabella · Attribution summary
"Your LDL-C dropped 48 points this quarter. The biggest driver was statin adherence at 97% — estimated −35 mg/dL. Saturated fat falling from 22g to 11g/day contributed an estimated −12 mg/dL, and weight loss added ~−8 mg/dL. Your next lever is soluble fibre — you're at 6g/day, half the therapeutic dose. Getting to 12g would likely add another −5 to −8 mg/dL by next test."

Questions
Common questions
LDL-C (low-density lipoprotein cholesterol) is the most commonly tracked and the primary target for cardiovascular risk reduction. ApoB (apolipoprotein B) is increasingly preferred by specialists - it directly measures the number of atherogenic particles and is more predictive than LDL-C, especially in people with metabolic syndrome or elevated triglycerides. If your lab offers ApoB, it's worth requesting. Lp(a) is a genetic marker worth checking once - it doesn't change with lifestyle and indicates inherited cardiovascular risk independent of LDL.
Yes - diet and lifestyle can reduce LDL by 10–30% in responsive individuals. The most evidence-backed interventions are: reducing saturated fat below 15g/day (replacing with unsaturated fats), increasing soluble fibre to 10–15g/day, adding omega-3 for triglycerides, exercising 150+ minutes per week, losing excess weight, and improving sleep. However, for people with familial hypercholesterolaemia or very high LDL (>190 mg/dL), lifestyle alone is typically insufficient - medication (usually a statin) is usually recommended alongside lifestyle changes.
Ziva doesn't connect directly to lab systems - you enter your results manually after each blood test. Isabella then plots your full panel history over time, calculates trends, and contextualises each value against optimal ranges and your personal targets. When you enter your next result, Isabella attributes the change to the habit data collected between tests - showing which interventions are working for your specific lipid profile.
Regular aerobic exercise (150+ min/week) raises HDL by 3–5 mg/dL on average and reduces triglycerides by 10–20%. Its direct effect on LDL is modest - but it shifts LDL particles from small, dense (more atherogenic) to large, buoyant (less atherogenic), improving cardiovascular risk even at the same LDL-C reading. Resistance training adds independent metabolic benefits. Ziva tracks your weekly exercise minutes from your wearable and shows how they correlate with your HDL and triglyceride trend between tests.
ApoB is increasingly the preferred marker in clinical practice. LDL-C measures the amount of cholesterol in LDL particles; ApoB measures the number of particles. Particle number is more directly predictive of cardiovascular events - two people with identical LDL-C can have very different particle counts. This discordance is common in people with insulin resistance, metabolic syndrome, or low HDL. If your lab offers ApoB, request it alongside your standard lipid panel. Ziva accepts ApoB as a tracked marker alongside the full lipid panel.
No. Ziva is a monitoring and adherence tool, not a clinical substitute. It helps you track your labs, habits, and medication between appointments - and share better information with your provider so every visit is more productive. Statin dosing, medication changes, and treatment decisions require a qualified clinician. Always follow your provider's guidance.
