MACHO is a holistic and innovative behavioral modification program designed to combat the childhood obesity epidemic at the grassroots level. The program partners with Public School 83 in East Harlem and aims to teach adolescents about nutrition and exercise through the lens of personal responsibility and practical tools for success in life. Although the immediate focus of our program is on healthy choices related to nutrition and exercise, MACHO's participants learn values and skills that can be applied to many other endeavors in life. By empowering our youth to lead healthy lives, we hope they can motivate and inspire others in their community to do the same.
