Weight loss and weight management diet products comprise structured nutritional offerings, including meal replacements, low-calorie foods and beverages, and dietary supplements designed to support healthy body weight and reduce chronic disease risk. The market was valued at USD 206.15 Billion in 2025 and is poised to grow at a CAGR of 8.30%. As per Phelps et al., 2024, more than 1 billion people worldwide were living with obesity in 2022, including approximately 880 million adults and 159 million children and adolescents, sustaining strong demand for diet-based weight management.
Rising Global Obesity and Overweight Burden is Set to Boost Weight Loss and Weight Management Diet Market Expansion
Rising demand within the market is increasingly linked to the escalating global burden of obesity and overweight, creating a stronger need for structured diet products that support healthy weight reduction. As per the World Health Organization fact sheet released in 2024, approximately 43% of adults aged 18 years and older were overweight in 2022 and 16% were living with obesity, more than doubling worldwide obesity prevalence since 1990. This surge has pushed consumers and providers to embrace meal replacements, high-protein foods, and clinically supported supplements, accelerating demand for weight management diet products globally.
A notable trend in the market is the rapid integration of artificial intelligence (AI) and digital health platforms into personalised diet planning, enabling tailored meal recommendations, real-time tracking, and improved adherence among weight management consumers.
Adoption of AI-Driven Personalized Nutrition is Likely to Boost the Market Demand
Manufacturers and digital health providers are increasingly adopting AI-driven personalised nutrition platforms that integrate biomarker data, dietary preferences, and behavioural insights to generate tailored weight management plans. As per Kim et al., 2024, published in Frontiers in Nutrition, large language model platforms such as ChatGPT can generate clinically applicable weight-loss diet plans for personalised use, supporting scalable adoption across weight management clinics. Companies are pairing AI tools with meal replacement, supplement, and digital coaching offerings, reinforcing sustained demand for weight management diet products globally.
