If its any help in 6ft 5 and weight just over 90kg which I believe is a little over 23bmi but now I'm 20 I'm concerned that I'll no longer burn fat as quick and start to become fatter and eventually overweight. So is this diet of mixed food maintainable or not. Again if its any relevance, my life style is mostly sat in a car traveling the country (England) but idk if that's relevant or not. To sum up, can I maintain a healthy weight or am I at risk of piling on the pounds?
Thankd for your help.
