Prep Kitchen provides chef-prepared meals designed to support individuals in achieving their health and fitness goals. Prep Kitchen was founded by Mark Morley and William Fishenden, who had been on their own health and fitness journeys, losing a combined 50kg. The company provides a range of menu options that are designed specifically for either muscle gain or weight loss. They now produce over 130,000 meals per week and sales hit £33m in 2025. Increased demand has been supported by promotion from Prep Kitchen’s network of athlete ambassadors, including World Champion & Olympic Gold Medallist, Anthony Joshua.
