With The Spurt In Healthtech, AI-powered apps Are Now All The Rage Offering Groundbreaking Interventions In Africa’s Battle against Rising Obesity Rates.
It’s an issue that affects a bulk of the continent’s population.
In Africa, where rising rates of obesity present a growing public health crisis, researchers and innovators are now turning to artificial intelligence (AI)-powered tools to combat the epi- demic. According to the World Health Organization (WHO), in 2022, 2.5 billion adults worldwide were classified as overweight, with over 890 million living with obesity. The problem is becoming especially urgent in low- and middle-income countries. In Africa alone, the number of overweight children under five has increased by nearly 23% since 2000, signaling a dramatic shift in public health needs across the continent.
One of the figures joining the battle against obesity through AI Richmond Essieku, a Ghanaian doctoral student at Texas Tech University. Essieku has reportedly identified 13 genes as potential biomarkers for obesity, with four of them already confirmed. His research is now being translated into a practical solution: an AI- powered mobile app, tentatively titled Generating Artificial Intel- ligence (AI) Based Algorithms to Model and Predict Genotype-by- Socioeconomic Status Interaction for Precision Obesity Detection. This app is designed to model the interaction between genetics and socioeconomic factors in order to provide a more accurate picture of obesity risk in individuals, particularly in Africa, where such nuances are often overlooked.
AI-powered tools like Essieku’s app are not the first examples of how AI can help address the complex factors contributing to obesity. Globally, AI has been used in various ways to combat obesity — from monitoring dietary habits to creating personalized fitness plans. In the United States (U.S.), platforms like Lark Health use AI to offer real-time health coaching, helping users monitor their eating habits and physical activity.

Similarly, Noom, a popular weight-loss app, uses AI to provide personalized advice and insights into user-behavior, which can lead to long-term lifestyle changes.
With the number of smartphone subscriptions in sub-Saharan Africa expected to reach 689 million by 2028, according to Statista, mobile technology offers a promising platform for AI-powered health interventions. AI-driven mobile apps can help individuals monitor their weight, track their food intake, and maintain healthy levels of physical activity. These apps can be tailored to include traditional African foods in dietary rec- ommendations, making them culturally relevant and easier for users to adopt.
The global applications point to the potential for similar systems tailored specifically to African contexts. Abideen Ola- supo, founder of MyAIFactchecker, an AI fact-checking platform based in Nigeria, highlights the importance of culturally-local- ized solutions. “We want to build people’s confidence in explor- ing how they can interact with AI to find safe and effective ways to combat obesity,” Olasupo tells FORBES AFRICA. “For a long time, many have turned to harmful concoctions that negatively impact their health. Africa’s unique challenges cannot be under- stood from the outside, which is why we’ve been researching the solutions people seek online. Obesity, in particular, is a sensitive issue that many feel ashamed to confront.”
MyAIFactChecker is one of several platforms working to ensure that AI solutions are tailored to Africa-specific chal- lenges. Olasupo explains that the platform sifts through different themes, including health and nutrition, to ensure that data is lo- calized and actionable. He notes that combating obesity in Africa requires integrating AI into the daily lives of Africans in ways that are culturally relevant and accessible.
AI’s ability to personalize interventions is especially critical when considering the unique challenges Africa faces in address- ing obesity. Many Africans live in ‘food deserts’ — areas where healthy food is difficult to find or too expensive to buy. Physical activity can also be limited by unsafe environments or long work- ing hours, making traditional approaches to weight-loss difficult to implement.
Africa’s healthcare infrastructure faces significant challeng- es, including a shortage of healthcare professionals and limited access to health facilities. AI is helping to alleviate these issues by offering remote monitoring and telehealth services for obesity management. In countries like Nigeria and Ghana, where access to healthcare is often limited, AI-powered remote health services could provide essential support to individuals looking to manage their weight.
AI-powered health apps are gaining popularity in Africa, also offering personalized recommendations for diet and exercise.
In Nigeria, the startup WellNewMe is using AI to provide us- ers with customized health assessments based on their lifestyle choices. The platform uses machine learning algorithms to ana- lyze users’ eating habits, physical activity, and medical history. It then generates recommendations to improve their health and reduce the risk of obesity-related conditions. For example, users can receive tailored meal plans, exercise routines, and lifestyle tips, all customized to their specific health profiles.
A similar initiative is underway in Ghana, where mPharma, a healthtech company, has developed the mymutti Mobile app. While primarily used to offer affordable medications, the app has recently integrated an AI-powered feature that tracks users’ body mass index (BMI) and offers recommendations for healthier liv- ing. Users receive customized tips on maintaining a balanced diet, increasing physical activity, and managing weight through simple lifestyle changes.
In Rwanda, AI is being used to improve access to healthcare in rural areas where obesity is on the rise. The Babyl Health plat- form, which uses AI to provide remote medical consultations, has been instrumental in helping individuals in rural communities access healthcare services. Through the app, users can consult with doctors about weight-related issues, receive prescriptions, and get referrals to local health facilities for further treatment.
Farming innovations to support the health sector
AI’s role in combating obesity extends beyond healthcare to the agricultural sector, where it is being used to improve the avail- ability of healthy, affordable food. In Nigeria, the startup Zenvus is leveraging AI to help farmers increase crop yields and reduce food waste. By using AI-powered sensors, Zenvus collects data on soil conditions, weather patterns, and crop health. This data helps farmers make informed decisions about when to plant, irri- gate, and harvest their crops, resulting in higher yields and more efficient food production.
Another example is FarmPin, a South African agritech com- pany that uses AI and satellite imagery to monitor crop health and predict food shortages. By analyzing data from farms across the country, FarmPin helps farmers optimize their production and ensure a steady supply of fresh produce to local markets. This, in turn, makes healthy food more accessible and affordable, reducing reliance on processed foods that are often linked to ris- ing obesity rates.
Public health experts are also optimistic about the potential of AI to offer scalable solutions for obesity prevention in Africa. Opeyemi Adam, a public health expert based in Lagos, explains that AI could help overcome some of the challenges of limited healthcare resources in many African countries. “Obesity is often thought of as a personal issue, but it’s deeply systemic,” Adam says. “AI offers a way to analyze large amounts of data and iden- tify trends that would otherwise go unnoticed, which is crucial in places where healthcare resources are stretched thin.”
Adam also points out that many Africans lack access to per- sonalized health advice, something AI could help bridge. “With AI, we could create more personalized health plans that take into account not just the individual’s body weight or fitness level, but also their lifestyle, environment, and even their genetic makeup,” he says.
