I'm 17 now and over the last few years (since I was 14 or so) I've gradually been putting on a bit of extra weight. I was in the overweight category of the BMI scale but I'm almost back to my ideal weight now. The highest weight I reached was about 70kg, so at the start of the overweight category but I'm now working my way back down to around 60kg (I'm 5'5). I'd say I only became in the overweight category during the last year, but between ages of 14/15 I was in the healthy weight bracket, but still at a higher percentile. I didn't exercise enough and the main thing wrong with my diet was probably sugar consumption, and eating too many sweets. Do you think this will have a significant negative affect on my health as I get older? Because I wasn't the ideal weight for around 3 years as a child/young adult, has this increased my chances of getting cancer or diabetes in the future? Or is it unlikely to make much difference seeing as I've nipped it in the bud while I'm still young? Thank you for your help, please don't say anything drastic because as you can see, I'm quite concerned.
