A May 2021 study by the University of Cambridge said, 

"These findings help us to better understand the experiences of autistic adults, and have wider implications for quality of life. We need to understand the reasons for restricted diet, limited exercise, and lack of sleep, to provide better support. This may include programmes for health education, and additional mental health support or supported living and working schemes."

"The challenges we see among autistic children regarding lifestyle behaviours extend into adulthood. Given the implications for risk of chronic disease and length of life, it is critical that we work to identify effective strategies for supporting health choices by autistic people of all ages."

"The wider picture suggests that autistic adults experience vulnerability in a variety of contexts, and this is just one new area that we should consider. Seeing that autistic adults are having such a hard time comparatively with healthy lifestyle habits has clear healthcare and policy implications: we need to create new and better support systems tailored to the specific needs of autistic people."
