Diet Pills Market Report 2025

The diet pills market size has grown rapidly in recent years. It will grow from $1.79 billion in 2024 to $1.99 billion in 2025 at a compound annual growth rate (CAGR) of 11.1%. The growth in the historic period can be attributed to increased awareness of health and fitness, rising obesity rates, changing lifestyles and dietary patterns, marketing and promotion strategies, medical endorsements and prescriptions.

The diet pills market size is expected to see rapid growth in the next few years. It will grow to $3.15 billion in 2029 at a compound annual growth rate (CAGR) of 12.2%. The growth in the forecast period can be attributed to continued focus on health and wellness, global increase in overweight population, expansion of weight management services, innovations in formulations and ingredients, growing e-commerce and direct-to-consumer channels. Major trends in the forecast period include technological innovations in formulations, emphasis on mental well-being, incorporation of appetite suppressants, digital health integration, expansion of online and e-commerce distribution.

The escalating issue of obesity is anticipated to drive the growth of the diet pill market in the future. Obesity, characterized by abnormal or excessive weight gain, typically with a body mass index (BMI) exceeding 30, poses significant health risks. It increases the likelihood of various cancers, including those affecting the esophagus, colon, rectum, liver, gallbladder, pancreas, and kidneys. Additionally, obesity is associated with the development of disorders such as type 2 diabetes (T2D) and cardiovascular diseases (CVD). Individuals struggling with obesity often turn to diet pills as a form of medication to aid in weight loss by reducing appetite and food cravings. For instance, as of May 2022, data from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) revealed that more than 2 in 5 adults (42.4%) have obesity, with approximately 1 in 11 adults (9.2%) experiencing severe obesity. Consequently, the increasing prevalence of obesity is a significant driver for the growth of the diet pill market.

The implementation of various initiatives is expected to contribute to the growth of the diet pills market. Initiatives involve specific actions, projects, or programs undertaken to achieve particular goals or address specific issues. One example is the initiative taken by Currax Pharmaceuticals LLC, a US-based specialty biopharmaceutical company and the manufacturer of the oral weight loss medication brand CONTRAVE (naltrexone HCl/bupropion HCl). In August 2022, the company launched a new campaign called "One Size Does Not Fit All," aiming to highlight the unique challenges faced by individuals dealing with overweight or obesity. The campaign emphasizes the necessity of a personalized approach to weight loss for long-term success. Therefore, the increasing adoption of initiatives is a driving force behind the growth of the diet pills market.

The increasing prevalence of chronic diseases is expected to drive the growth of the diet pills market. Chronic diseases, characterized by conditions or illnesses that last for more than a year and require ongoing medical treatment, necessitate comprehensive management approaches. These approaches often involve lifestyle modifications, such as adopting a balanced diet, engaging in regular physical activity, and making behavioral changes. As of January 2023, data from the National Library of Medicine, a US-based agency, suggests that the number of people in the US aged 50 and older with at least one chronic condition is projected to increase to 142.66 million by 2050. The rising prevalence of chronic diseases will consequently contribute to the growth of the diet pills market.

The popularity of plant-based supplements emerges as a key trend in the diet pill market, with companies developing plant-based diet pills to maintain their market positions. For instance, in April 2022, Wellbeing Nutrition, an India-based plant-based nutrition company, launched SLOW, a formulation consisting of 13 supplements catering to various health and wellness needs, including reproductive support, bone health, weight loss, and daily multivitamins. The SLOW technology employs continuous-release coated pellets in a capsule to ensure the timely digestion of vitamins and nutrients throughout the day. This new line is designed to meet consumer demands for increased energy, physical endurance, mental alertness, and functional health benefits for disease prevention.

In November 2022, Audax Private Equity, a US-based middle-market investment company, acquired Medi-Weightloss, Inc. for an undisclosed amount.
