1-Daniel loves junk food. He is on the school soccer team.
2-Jack eats nutritious food most of the time but indulges in junk food once in a while.
3-Mark prefers nutritious food, helps his father in the garden, and walks his dog regularly.
4-Steve loves junk food and hates any kind of physical activity.
Type 2 diabetes is the result of poor diet and poor lifestyle. Steve loves junk food which will be high in sugar which is a leading contributing factor in developing diabetes. He also does no kind of physical activity so he will not be burning off the high calorie food he intakes putting extra pressure on his body and organs.
Okay well if none of them can get diabetes through genetics it would be the person with the worst eating and the one with a lack of physical activity witch would be Steve.
