Plant-based and sustainable diet: A systematic review of its impact on obesity.

Abstract in brief

• The food system impacts the environment through practices like livestock farming and food waste, with animal products contributing more to greenhouse gases than plant-based foods, leading to a push for plant-focused diets such as the EAT-Lancet model that are both eco-friendly and promote health.
• Sustainable diets aim to reduce environmental damage while addressing health issues like obesity and chronic diseases, emphasizing a shift towards plant-based foods to lessen ecological pressure and improve public health.
• A systematic review shows that following a healthy plant-based diet is linked to lower obesity rates, especially measured by BMI and body fat, but more research is needed to confirm these findings and establish stronger conclusions.]
