At Doctor Sacher & Co. we're constantly reviewing and assimilating the latest evidence for the application of AI in behaviour change, coaching and weight management.



Given that most systematic reviews include studies conducted before the launch of Gen AI chatbots like ChatGPT, the present research landscape understandably presents a growing yet still emerging perspective on this dynamic field.

Key Insights:


AI Agents for Weight Management:
Chew's review (2022) emphasises AI chatbots ability to provide personalised, engaging, and 24/7 support for people aiming for weight loss. By integrating user data, including health metrics and personal preferences, AI chatbots offer tailored advice and motivational support, potentially enhancing weight loss outcomes.

AI Chatbots for Behaviour Change:
A review by Aggarwal et al. (2023) assessed AI chatbots' feasibility, efficacy, and intervention characteristics in promoting health behaviour change. Their findings underscored success of chatbots in encouraging healthy lifestyles. However, they also pointed out the need for more rigorous studies to confirm these preliminary results conclusively.

Personalised Approach:
Studies, such as those by Terblanche et al. (2022) and Chew (2022), demonstrate AI's capability to offer personalised coaching. AI chatbots have have shown efficacy in goal attainment, providing users with tailored support and guidance.

Accessibility and Scalability:
One of AI's most significant advantages is its potential to make coaching more accessible and affordable. By leveraging AI, coaching services can reach a broader audience, overcoming traditional barriers like cost and availability.

Evidence of Effectiveness:
While initial findings on goal attainment are encouraging, results in areas such as psychological well-being and resilience are still inconclusive. This highlights the infancy of AI in weight management and the need for further research to understand its full impact.

Looking Ahead:
This body of research highlights the nuanced capabilities and challenges of AI in health coaching and weight management. As we advance, there's a clear horizon where AI chatbots could democratise access to personalised health coaching, making significant strides in public health and individual wellness.
As health professionals and innovators, we must continue exploring these technologies, ensuring they're leveraged to their fullest potential, ethically and effectively. The journey towards integrating AI into health and wellness is just beginning, and its future looks promising.

At Doctor Sacher & Co., we are committed to staying informed about the latest research and integrating evidence-based AI solutions into our practice.
