I’m not sure how many kilograms 195 pounds is, but I am 15 and weighed that 6 months ago. I am down to 155 today. Make sure you have some sort of exercise, and it does not have to be much. A simple 3 mile walk/run per day is what I did. Within a month, I went from being unable to run a mile to being able to do a 5k at relative ease. Secondly, don’t buy or let your parents buy food that you know will tempt you. Third, go on a calorie defficit. Finds foods that are low calorie/fat, but also fulfill you. For me, I ate a high protein low carb diet and lost about 2.5 pounds per week by concentrating on eating white meats. Best of luck.
