So you want to be scared into giving them up. My weight increase was due to a) sitting at computers for hours every day and b) eating too much chocolate.
As a result I have high blood pressure and an enlarged heart (larger than 97% of other people my age, apparently, and that was determined by an MRI scan). This is not as I tried to suggest because I am a kind, generous person, but because my heart is working overtime to force the blood through my arteries. I am not diabetic yet, but would have been soon if I had not done something about it.
I have recently given up all sweet things - ice creams, biscuits, chocolate, cake, fizzy drinks etc and instead I am eating much more healthy food. When I get hungry I have a drop of milk and a small handful of raisins, which takes away the hunger pangs.
By sticking to this regime and doing more walking and work in the garden, I have lost 12.5 kg and counting over the last few months.
So, yes, you could have a heart attack. You could have high blood pressure. You could have high cholesterol. You could have an enlarged heart. And you could soon be diabetic.
Is that scary enough????
By the way, I see you give your measurements in imperial units. Don't do that. Instead, convert these to metric (60 kg and and 1.68 m in your case) and then you can work out your Body Mass Index (BMI) by dividing your body mass in kg by your height in metres and again by your height in metres (in your case, that is 60/1.68/1.68 = 21.25). Your BMI should be between 20 and 25, so you are well inside that range - at the moment. Go over 25 and you are officially fat (you may prefer to say 'overweight') and over 30 you are officially obese.
At the moment, you are okay, but the danger comes, of course, if you continue this habit and your BMI slowly increases. Obesity creeps up on us in unexpected ways.
By the way, I am not medically qualified so if you are worried about anything medical, seek the advice of a professional. (That last bit is just to cover myself, but I guess you knew that already!).
