Brief Summary

Two randomized control trials examining human food choice (i.e. selection of high energy 'unhealthy' foods vs. selection of healthier foods). Interventions: In a between-subjects design, participants (recruitment stratified by socioeconomic position) made food choices (main dish, plus optional sides and desserts) in the absence vs. presence of menu energy labelling and from menus with baseline (10%) vs. increased availability (50%) of lower energy main dishes. Main outcome measures: Average energy content (kcal) of main dish chosen and average total energy content of all food ordered, including optional sides and desserts.

Outcome Measures

Primary Outcomes (1)

  • Energy ordered from main menu

    Total kcal content of main menu order

    15-20 minutes (the time frame denotes time taken to make the menu order and there is no follow up

Secondary Outcomes (1)

  • Total energy ordered

    15-20 minutes (the time frame denotes time taken to make the menu order and there is no follow up

Study Arms (4)

Energy labelling

EXPERIMENTAL

Energy labelling provided on restaurant menus

Other: Menu configuration (presence of energy labelling)

No energy labelling

NO INTERVENTION

No energy labelling provided on restaurant menus

Increased availability of lower energy meals

EXPERIMENTAL

Higher proportion of meals are 600kcals or less

Other: Menu configuration (presence of energy labelling)Other: Menu configuration (more lower energy options added)

Baseline availability of lower energy meals

NO INTERVENTION

Proportion of meals that are 600kcals or less at baseline level

Interventions

Restaurant menus are altered to accommodate energy labelling intervention

Energy labellingIncreased availability of lower energy meals

Restaurant menus are altered to include more lower energy options

Increased availability of lower energy meals
