MIND Diet vs Volumetrics
A side-by-side comparison — no verdict on which is "better," just how they differ.
MIND Diet
A hybrid of the Mediterranean and DASH diets, built specifically around brain health, scored on 15 food components with extra emphasis on berries and leafy greens.

Organizes eating around a food’s energy density (calories per gram) rather than restricting any food group — building meals around lower-density, water- and fiber-rich foods to feel full on fewer calories.
View full Volumetrics page →Key Differences
These two are close on paper, so the differences are smaller than in most pairs.
- Volumetrics lowers calories by favoring foods with fewer calories per bite, while MIND has no calorie target of its own.
- They differ a lot in strictness. Volumetrics sets few hard rules and bans nothing outright, while MIND works through targets and limits rather than food-group bans.
What They Share
Vegetables, whole grains, and beans and lentils are staples in both.
Typical Foods
MIND DietGreen leafy vegetables (six or more servings a week), other vegetables, nuts, berries (especially blueberries), beans and legumes, whole grains, fish, poultry, olive oil, and wine in moderation.
VolumetricsVery-low-density: broth-based soups, non-starchy vegetables, most fruit. Low-density: starchy vegetables, whole grains, legumes, low-fat dairy, lean protein — the everyday staples.
Foods to Avoid
MIND DietRed meat, butter and stick margarine, cheese, pastries and sweets, fried or fast food (the 5 components to limit).
VolumetricsNone eliminated — higher-density foods (nuts, seeds, dried fruit, oils and butter, chips, chocolate, cookies) are enjoyed in smaller amounts, not banned.
Eating Pattern
MIND DietNo specific eating window — scored on 15 food components, not timing.
VolumetricsNo specific eating window — organized around food energy density, not timing.
Primary Goal
MIND DietLong-term brain and cognitive health (Alzheimer’s disease risk).
VolumetricsWeight loss via increased fullness/satiety per calorie.
Best For
MIND DietPeople prioritizing long-term brain and cognitive health who want a sustainable, food-based pattern close to Mediterranean or DASH but with a sharper berries-and-greens focus.
VolumetricsPeople who find restriction-based dieting hard to sustain because they end up hungry, and who like understanding the “why” behind a recommendation.
Macro Emphasis
MIND DietNone specified.
VolumetricsNone — organized around energy density (calories per gram), not macro ratios.
Health Condition Relevance
MIND DietCognitive decline / Alzheimer’s disease risk — its primary, purpose-built focus.
VolumetricsNot tied to a specific health condition — a general weight-loss/satiety focus.
Evidence Strength
MIND DietMixed — the original 2015 cohort found 53% lower Alzheimer’s risk (top vs. bottom adherence tertile), but the one major randomized trial (NEJM 2023) found no significant cognitive advantage over a calorie-controlled control diet over 3 years, directly complicating the earlier finding.
VolumetricsModerate. A decades-long Penn State research program (Dr. Barbara Rolls) shows lower energy density reduces calorie intake, and a year-long trial in 97 women found adding fruit and vegetables to a reduced-fat diet led to more weight loss and less hunger. A 2022 meta-analysis found no significant weight effect, and long-term results are inconsistent.
Restrictiveness
MIND DietLow-to-moderate — food-component scoring rather than hard rules, similar structure to Mediterranean/DASH.
VolumetricsLow — no foods eliminated, just density-tier awareness; requires some ongoing attention to food composition rather than fixed rules.
Cost / Accessibility
MIND DietCosts more than a standard mixed diet given its reliance on berries, fish, olive oil, and nuts, similar in price to Mediterranean and DASH, and for households on a fixed or limited food budget, may exceed what's practical to sustain long-term.
VolumetricsBuilt on inexpensive, widely available staples (produce, whole grains, legumes, broth-based soups, lean protein) with no specialty products required, making it one of the more budget-friendly structured approaches.
Nutrients to Watch
MIND DietNot studied. No research has measured nutrient gaps on MIND. In its main trial, blood carotenoid levels rose, a sign of higher fruit and vegetable intake.
VolumetricsNo gaps are documented. Low-energy-density diets are linked with higher intake of vitamins A, C, and B6, folate, iron, calcium, and potassium.
Adjustment Period
MIND DietLittle is known. In a three-year trial, side effects were no more common than on the control diet. Beans more than three times a week may cause some gas at first.
VolumetricsLittle is known. In its main year-long trial, the group eating more fruit and vegetables reported less hunger, not more.
A Sample Day
MIND DietBreakfast: oatmeal with blueberries and walnuts. Lunch: leafy-green salad with chickpeas and tomatoes, dressed with olive oil. Dinner: baked salmon or chicken with brown rice and roasted vegetables. Snack: a small handful of almonds.
VolumetricsBreakfast: oatmeal with berries and a hard-boiled egg. Lunch: broth-based vegetable soup, then a turkey sandwich on whole-grain bread with lettuce and tomato. Dinner: big green salad, grilled fish, brown rice, and roasted vegetables. Snack: grapes with nonfat Greek yogurt.
Prep and Eating Out
MIND DietModerate prep, with daily vegetables, whole grains, and regular beans and fish. Eating out is fairly easy, since the diet sets limits rather than bans.
VolumetricsLow to moderate prep, since soups and salads can be made in batches and nothing is tracked. Easy to eat out: start with a broth-based soup or salad and fill up on vegetables.
Talk to a Clinician First If
MIND DietWine is part of the original scoring, but people who don’t drink are advised not to start. Warfarin users should keep leafy-green intake steady. The research was done in older adults, so there is no specific guidance for pregnancy or children.
VolumetricsNot studied. No specific cautions have been published for Volumetrics.
Sticking With It and Stopping
MIND DietIn a three-year trial, 93% of participants finished, and diet scores improved within six months and stayed there. Participants were given some foods and dietitian support, so real-world adherence is unknown. Nothing is known about what happens after people stop.
VolumetricsIn its year-long trial, about 73% of participants finished. In a small seven-month trial, a low-energy-density diet reduced weight regain after weight loss. Over the long term, lower-density diets have not consistently produced more weight loss than calorie restriction alone.
