When you want to burn fats, and want to have good diet, and you are just alone, most of the time, you'll find yourself giving up after a couple of days or weeks without fulfilling and achieving the desired weight. Why? Because you get bored and tired.
Sometimes, you need a companion or someone to be with you on this process. And most of the time, it's more effective than doing it alone. When you have a friend, ask him/her to accompany you or much better to join you. You can talk and schedule your time and workout together, advice each other every time someone forget the diet plan. And you'll feel less effort and stress in dieting. Instead of feeling tired, you'll find yourself enjoying during the process. Try it, then you'll see :)
