Average meal types (breakfast, lunch, dinner) were assessed using life cycle assessment. Retail consumer wastes, weight losses gains through cooking, used adjust quantities production quantities. On average, had more than a 40% reduction for any indicators (carbon footprint, water use, resource consumption, health pollution, ecosystem quality). At maximum minimum carbon dinners associated with 5 kgCO2e lunches 1 kg CO2e. Results indicate that, on average US, lessen comparison meals; however, animal products (i.e., dairy) also substantial impact. Findings suggest that industrial interventions focusing low-impact meat substitutes thereafter lunches, dairy breakfasts, offer large improving performance diet.
