My son managed to drop 10 kg in 12 weeks. He weighs 74 kg now.
He did it by portion control and a bit of exercise.
The first thing I did was to stop making snacks,cakes and tarts. Every time he felt like having a snack he had a fruit. ( Bananas or apples). He loves canned fruits, so once a week he had a small serve of mixed fruit in apple juice as a treat. Other than that he hasn’t had a slice of cake, serve of ice cream or a chocolate bar the last 12 weeks.
He stopped eating fast-food completely. Reduced the quantity of food he consumed which really worried me for I couldn’t bear to think that he would feel hungry. Mom, it is for the greater good, he said.
He went on the bike regularly every day the first 6 weeks and then he lost the motivation. I didn’t want to nag him because he already lost so much weight and I knew if I continued with portion control he would be fine. He walked the longest route from his school to the bus stop everyday. he played basketball twice a week.
My point is this. You can really lose weight, if you are determined. You do not need to consume any magic potions that claim to burn fat or follow some stupid diet. All you need to do is eat what you really want to, but in smaller portions and walk.
Walking is free, cheap and efficient way to burn calories.
