Iron is commonly underconsumed especially for girls as they lose blood during menstration. A consequence of not getting enough iron can lead to developing anemia.
An unhealthy lifestyle can lead to obesity as excercise goes helps to burn off the kilocalories from your food but when you are not excercising regularly this can lead to an energy imbalance which is when you take in more kilocalories then you use the energy from your food is stored in your body in the form of fat. Another consequence is if you take in too much sugar the hormone in your body called insulin which helps maintain a regular blood sugar level will not be able to control your bloood sugar level and this can lead to you developing type two diabetes and therefore you will need to inject insulin into your body and you will have to keep a check on your blood sugar levels constantly.
hope this helps you and if you have any questions let me know also if you could mark this as brainliest i would really appreciate it!
