Hello doctor Samuel , I wanted to ask you a question that nobody in my country probably wont know how to answer since theres nobody that takes care for fitness and diets. Well I lived in america for a year and i gained like 10 kg , and now that I m back home i lost those kg, but I still have a big apetite and I m so afraid I will be gaining weight.It is very bad because I m always thinking about food and that I should not eat ,and keep with my strict diet that I ve been keeping since 3 months .Please help , its becoming very bad habit in my brain to think so much about food ,and then sometimes eat like crazy ! thank you very much , hope you reply soon.
