Impact of a Short-Term Mediterranean-Style Diet on Health Indices (MEDWELL)
15. juli 2026 opdateret af: DR ADELE COSTABILE, University of Roehampton
Exploring the Effects of a Short-term Mediterranean-style Dietary Intervention on Indices of Mood and Wellbeing in UK Adults
Emerging evidence suggests protective properties of a Mediterranean diet (MD) in relation to prevention and management of mood disorders.
However, there is paucity of dietary interventions investigating adherence to MD and effects on mood and wellbeing in individuals without a clinical diagnosis.
The present study aimed to investigate the effects of adherence to a short-term MD on mood and wellbeing in healthy adults

Aktiv komparator: A Mediterranean style diet
At baseline, participants attended an Educational Group Session (EGS) introducing the principles of the Mediterranean Diet (MD), including recommended foods, foods to limit, cooking methods, and shopping tips.
Participants then followed a Mediterranean-style diet for 7 days, replacing typical Western foods with MD alternatives without restricting energy intake.
Practical examples and take-home materials with simple food swaps were provided to support adherence.

At baseline, an Educational Group Session (EGS) introduced participants to the Mediterranean Diet (MD) principles to support adherence.
The interactive EGS covered MD typical foods to consume and avoid, cooking methods, and practical shopping guidance.
Following the EGS, participants adopted a Mediterranean-style diet for a period of 7 days.
Participants were encouraged to follow the MD guidelines (replacing typical western foods with MD foods) without restricting energy intake; examples were provided during the EGS and with take-home resource materials which detailed 'simple swaps' or alternative MD food items to replace western food items.

Mood
Tidsramme: Baseline and 7 days (final day of each condition) espressed in questionnaire scores
|
Change in mood measured using the Bond-Lader Visual Analogue Scale (VAS).
The scale ranges from 0 to 100, with higher scores indicating a more positive mood state (better outcome).

Body weight
Tidsramme: Baseline and 7 days (final day of each condition) expressed in Kg
|
Change in body weight, measured in kilograms (kg) Change in waist circumference, measured in centimetres (cm). Lower waist circumference indicates a better outcome where reduction in central adiposity is a study objective. |

Physical activity
Tidsramme: Baseline and 7 days (final day of each condition) espressed in questionnaire scores
|
Change in physical activity measured using the International Physical Activity Questionnaire (IPAQ), expressed as total metabolic equivalent (MET)-minutes per week.
Higher scores indicate greater physical activity levels (better outcome).
The IPAQ does not have a fixed minimum or maximum score.

Dietary intake
Tidsramme: During the 7 days intervention/condition using DietPlan software
|
Change in dietary intake assessed using 7-day weighted food records collected during each 7-day intervention period.
Dietary intake was quantified as daily energy and nutrient intake.
There is no fixed minimum or maximum score; values are reported in their respective units (e.g., kcal/day, g/day).
The direction of a better outcome depends on the specific dietary component being evaluated.
