Paleo Diet vs Whole30

Paleo DietGrass-fed beef, chicken, wild-caught salmon, eggs, almonds, walnuts, pumpkin seeds, berries, apples, leafy greens, broccoli, sweet potatoes, olive oil, avocado.

Whole30Chicken, beef, pork, fish, shellfish, eggs; all vegetables and fruit; compliant fats (olive oil, coconut oil, avocado, ghee); some nuts and seeds (not peanuts).

Paleo DietWheat bread and pasta, rice, oats, beans and lentils, peanuts, milk, cheese and yogurt, table sugar, chips, and packaged snacks.

Whole30Added sugar (real and artificial), alcohol, grains, legumes (including peanuts and soy), dairy (ghee is an exception); also “SWYPO” compliant-ingredient treat mimics like paleo pancakes.

Paleo DietNo specific eating window — restricts food categories, not calories, macros, or timing.

Whole30Strictly time-boxed: 30 days of elimination, then foods reintroduced one group at a time over a minimum 10-day period.

Paleo DietGeneral health by cutting processed foods, added sugar, and refined carbs, modeled on ancestral eating.

Whole30Self-experiment/reset to identify personal food sensitivities, not weight loss or long-term eating.

Paleo DietPeople who feel or perform better cutting out processed foods, added sugar, and refined carbs generally, regardless of whether the ancestral framing itself holds up.

Whole30People who want a short, structured reset with a built-in process for identifying personal food sensitivities.

Paleo DietNone specified — restricts food categories, not macro ratios.

Whole30None — no macro or calorie structure, only an exclusion list.

Paleo DietModest improvements in glucose tolerance (small RCT in people with ischemic heart disease), weight, waist circumference, blood pressure, and lipids in a meta-analysis — evidence the study authors themselves call “not conclusive.”

Whole30None specific — framed around identifying personal food sensitivities generally, not any named condition.

Paleo DietLimited/thinner — real but noticeably thinner and shorter-term than Mediterranean or DASH; a supporting meta-analysis had published calculation-error concerns, and the “one ancestral diet” premise has been directly challenged in the scientific literature.

Whole30Limited: no independent clinical trials — only an unpublished, non-peer-reviewed company pilot cohort (~45 participants) plus self-reported alumni surveys. Cleveland Clinic calls it “an experiment,” not an evidence-backed treatment.

Paleo DietHigh — restricts entire food categories (grains, legumes, dairy) rather than counting anything.

Whole30High — strict, time-limited elimination of multiple food groups at once.

Paleo DietPaleo-compliant meat, fish, nuts, and produce typically cost more than the grain, legume, and dairy staples it excludes.

Whole30Relies heavily on compliant packaged condiments, dressings, and marinades that typically cost noticeably more than standard equivalents, though cutting alcohol, takeout, and processed snacks for the 30 days can offset some of that premium.
