If you are trying to lose weight but still you are gaining then you should check whether you are doing these four acts or not, because they may be the reason for your gain in weight.
1) Snacks at night should be avoided completely, or skip the dinner and just eat some snacks. Combining both is disastrous because it gives you extra calories which converts into fat.
2) Eating while watching TV is another dangerous thing to do, those who watch TV for long hours prefer to eat something while watching TV. This adds extra calorie which are not needed by your body.
3) Using smart phones on bed is another reason for your increasing weight, we need proper sleep for our body and digestive system to work properly.
4) You should wake up early and do some exercise for going to your office or school. It will help in burning calories and will also make you healthier.
