Healthy Living

Empowering and enabling people to make life choices that benefit their health—including nutrition, sleep, engagement with technology, physical activity, and social connections—while addressing the systems and structures that can significantly impact one’s ability to make those choices

The global disease burden is strongly related to behavioral factors including dietary choices, sedentary lifestyles, smoking, alcohol, and poor medication adherence. Creating awareness about and changing these behaviors also represents a major opportunity to improve health and well-being. A balanced and healthy diet, sufficient and regular sleep, and moderate physical activity are just a few of the elements that enable healthier living. Social connectedness and living a purposeful life also promote better health outcomes, suggesting that the way we live our lives—our actions, decisions, and relationships—has a substantial impact on our health and life spans.

The communities of which we are a part are an important enabler of healthy lives. They provide and maintain structures that further support health, promote healthy behaviors, and foster consciousness around the importance of health as an asset. Governments and healthcare providers, as well as employers, schools, and other institutions play a central role in promoting healthy lifestyles by providing health education, better access to infrastructure, and a higher investment in preventive care.

As science increasingly grasps the behavioral determinants of health and society grows more health conscious, it becomes essential to address the main barriers preventing people from adopting healthier lifestyles. These include the socio-economic context, cognitive biases about health, misaligned incentives to adopt healthy habits, and insufficient information about the health consequences of certain behaviors.

The path toward healthier lives also requires a significant reallocation of health spending: governments, employers, and communities will need to disproportionately invest in disease prevention and health promotion, in addition to curative care.

Lastly, enabling healthier lives globally requires accounting for the different challenges countries and regions face. Low-income areas might benefit most from access to sanitary infrastructure and food security, while high-income may need to consider sedentary lifestyles.

Topics to explore

In collaboration with relevant stakeholders, the McKinsey Health Institute (MHI) is interested in exploring long-term questions such as:

  • How can we work across the many silos to drive meaningful and sustainable improvements in healthy living?
  • How best can we equip and enable individuals to live their best possible lives?
  • What if everyone got enough regular sleep? What would it take to change attitude toward sleep and turn its reputation from “lost time” into “active recovery”?

How the world could better fight obesity

– If the prevalence of obesity continues on its rising trend, almost half of the world’s adult population could be overweight or obese by 2030, imposing even greater personal, social, and economic costs. Effectively combating obesity around the world may require a comprehensive strategy of 44 interventions as part of a potential Obesity Abatement Program.
