How It Works
Each diet gets a baseline health index (0-100) summarizing its typical effects across blood pressure, cholesterol, blood sugar, and weight, drawn from broad population research: DASH 85, Mediterranean 82, low-carb 78, vegetarian 76. DASH leads because it was built specifically to lower blood pressure. The Mediterranean pattern scores strongly on cardiovascular and longevity markers, low-carb on glycemic control and short-term weight, and vegetarian on LDL cholesterol. The index is then scaled by a duration factor (weeks divided by 12, capped at 1.5) because benefits generally accumulate over time, and a small weight factor if you start above 200 pounds, since higher starting weight allows more measurable change. The chart ranks the four for your timeframe. Scores are relative reference summaries, not clinical predictions.
What Should You Do?
Pick the pattern you can follow for years, not weeks. DASH and Mediterranean are the most evidence-backed for heart health and are flexible enough to suit most people; low-carb can help short-term glucose and weight but needs care for saturated-fat quality; vegetarian supports cholesterol but watch protein and B12. None requires perfection, and small consistent shifts beat strict adherence that collapses. Use the comparison to set expectations over your planned weeks, then track real metrics like blood pressure and weight with your clinician. This is educational reference, not a prescription, and medication should never be changed from it.
Frequently Asked Questions
Which diet is healthiest overall?
On this index DASH ranks highest, with Mediterranean close behind, both strongly evidence-backed for cardiovascular health. The best is the one you sustain.
Why does low-carb score lower?
It scores well on glucose and weight but less consistently on long-term heart markers, so its combined index lands a bit lower here.
Do benefits really grow with weeks?
Generally yes, improvements in blood pressure, lipids, and weight accumulate over months, which the duration factor reflects, capped at 1.5.
Are these scores clinical?
No. They are relative reference summaries of population studies, meant to compare patterns, not to predict your result.
Can I mix patterns?
Yes. A Mediterranean-style plan with lower carbs or more plants is common and often sustainable. The scores are per single pattern.
Should I stop my meds if a diet helps?
Never. This is educational reference. Any medication change must be guided by your clinician using real measured readings.

Diet patterns differ from diets: they are sustainable ways of eating, not short fixes, and their health effects show up across many metrics at once. The DASH pattern was designed and tested to lower blood pressure and does so reliably. The Mediterranean pattern, built around olive oil, fish, vegetables, and whole grains, is consistently linked to lower cardiovascular risk and longer life. Vegetarian patterns tend to improve LDL cholesterol and weight. Lower-carbohydrate patterns often produce faster short-term drops in blood sugar and weight, useful for some goals. Comparing them on a single health index clarifies that no pattern is universally best; the right one matches your health targets, food preferences, and ability to keep it up, ideally with a clinician's input.
