How to read these scores
Sustainability
Weighted heaviest. Adherence predicts outcome more reliably than macro split, so an approach nobody can keep scores low here even when the trial data looks good.
Short-term effect
A high number here alone means very little. Water and glycogen move fast, and almost every restrictive protocol looks impressive at week four.
Long-term effect
Where short-term and long-term diverge sharply, you are usually looking at a regain mechanism built into the design — not a willpower failure.
What it promises — and how it says it works
The claim
What it claims
The Mediterranean diet — olive oil, fish, vegetables, legumes, whole grains, nuts, fruit, modest wine, limited red meat and processed food — is consistently associated with lower cardiovascular events and longer healthspan in observational and trial data. It's the only diet pattern with robust evidence for hard cardiovascular endpoints (PREDIMED).
The mechanism
How it is supposed to work
The mechanism is dietary pattern, not single-nutrient. High polyphenol intake from olive oil, vegetables, and wine; high omega-3 from fish; high fibre from legumes and grains; minimal UPF and seed oils. The fatty-acid profile (high MUFA, moderate omega-3, low omega-6 industrial seed oils) supports endothelial function and reduces inflammation.
What the research actually shows
PREDIMED² (Estruch 2018 NEJM) showed Mediterranean + olive oil or nuts reduced major CV events by ~30% in high-risk adults. Lyon Diet Heart Study¹ (de Lorgeril 1999) showed ~70% reduction in cardiac events post-MI. Meta-analyses consistently support cardiovascular and metabolic benefit. For weight loss alone, Mediterranean is moderate — slower than keto in the first 6 months, but produces equivalent loss at 24 months with better cardiovascular biomarkers.¹²³⁴

Evidence rating
Strong evidence
Describes the quality and quantity of the peer-reviewed literature — trial count, duration, sample size and replication — not our opinion of the approach.
Early loss is not evidence. Glycogen carries roughly three grams of water per gram, so the first pounds on almost any restrictive protocol are largely water. What matters is what is still there at twelve and twenty-four months.
Right person, wrong person
Almost nothing on this site is universally good or universally useless. The useful question is which body, kitchen and calendar an approach was built for.
Worth a trial
Who it works for
Almost everyone. The Mediterranean pattern is the strongest evidence-based dietary pattern for general health. Especially good for adults with cardiovascular risk, metabolic syndrome, or family history of heart disease. Compatible with most cultures, religions, and budgets.
Look elsewhere
Who it fails
Adults with severe insulin resistance who do better with deeper carb restriction. Athletes optimising body composition who need higher protein. People who interpret 'Mediterranean' as 'pasta and bread' — the actual pattern emphasises vegetables, legumes, fish.
Mediterranean has the strongest evidence base of any dietary pattern for cardiovascular and longevity outcomes. It's not optimised for rapid weight loss — but for sustainable lifelong eating, it's the default we'd recommend if forced to pick one pattern. Pair with resistance training and adequate protein for body composition.
Written against the rubric, not against a sponsor. Individual response varies and no outcome is guaranteed.
What to do instead
Adopt Mediterranean as your long-term default. Modify for body composition by increasing protein toward 1.6 g/kg.

Straight answers
Mediterranean Diet, without the spin
We score Mediterranean Diet 9/10 for sustainability, 5/10 for short-term effect and 9/10 for long-term effect. A gap between the short-term and long-term numbers is the single most common pattern in this index — an approach can move the scale quickly and still leave almost nothing behind eighteen months later.
Sustainability is weighted heaviest for a reason: across head-to-head trials, adherence predicts outcome more reliably than which named diet you picked. A protocol you abandon in week six did nothing at all.
Can you still be doing this in month twelve?

Did Mediterranean Diet not work for you?
That is the rule rather than the exception, and it is usually a design problem in the protocol rather than a character problem in you. The assessment reads your situation and points you at the approach the research supports for that profile.
