Healthy lifestyle changes

Hey my name is Justine , and I am making lifestyle changes for better health . In my family on my moms side there is a history of diabetes , high blood pressure , strokes , and other things .I want to change this before I get married and have kids . I don't just want to be on a diet I want a healthy lifestyle that will last even after I lose weight . I am doing this for me , and the people that love me . Most of my family members are taking medicine for blood pressure , diabetes, IBS etc . and I don't want that for myself . I am ready for change I'm gonna do it .
