Can someone help me with this please ASAP

What a self improvement for a busy person who had difficulty finding time to exercise/ dropping out of clubs and activities/ refusing social invitations from friends/ scheduling daily invitation activity/ sleeping fewer hours at night

(hope) unrealistic portrayals of slim bodies can encourage people to lose an unhealthy amount of weight. being underweight or malnourished can lead to a. liver abnormalities b. tendon rupture c. muscle damage d. heart issues

How could you find out if that advice is based in scientific evidence?
