Passive income: NO

Earning passive income solely from an AI personalized nutrition and meal planning service is challenging due to the ongoing need for updating algorithms, customer support, and adapting to changing dietary trends. While automation tools can help streamline some processes, such as meal plan generation, ongoing monitoring and adjustments are typically required to maintain customer satisfaction. Most individuals in this industry do not achieve true passive income without branching into related income streams like affiliate marketing or selling related products. Setting up systems like automated emails and customer support can reduce time commitment, but significant ongoing effort is still needed to keep the service running smoothly. It's realistic for a few outliers to achieve passive income, but for the majority, active involvement is necessary to sustain the business.
