Obesity has become a major global public health concern, contributing to numerous chronic diseases and reduced quality of life. In addressing this epidemic, dietary interventions, particularly the inclusion of nutrient-dense foods such as nutri-cereals, have gained significant attention. Nutri-cereals, including whole grains like millets, quinoa, and amaranth, offer a promising strategy for obesity management due to their high fiber content, low glycemic index, and rich profile of essential nutrients and plant-based proteins. These properties enhance satiety, reduce appetite, and support improved metabolic regulation, all of which contribute to effective weight management. Additionally, nutri-cereals provide versatile culinary applications, offering gluten-free alternatives and a range of cooking options that promote adherence to healthier eating habits. Emerging evidence also suggests that their consumption may improve gut health by fostering a balanced microbiome, further reducing obesity risk. This chapter highlights the potential of nutri-cereals as valuable dietary components in obesity management, emphasizing their nutritional benefits, satiety-inducing effects, and positive impact on gut health. However, further research, including long-term studies and large-scale interventions, is needed to fully understand their role and support their integration into public health strategies for obesity prevention and treatment.
