One thing to keep in mind, is if you don't eat enough calories, your body will go into starvation mode....and the weight will not come off.
some of the rules to try and follow:
Eat breakfast, with a protein.
Eat 5 or 6 times a day.
Drink 6 to 8 glasses of water each day.
The high protein, low carb diet is supposed to be good for weight loss but for me, I would have a very hard time giving up the carbs...only you know if you can be so restricted and be successful.
Good luck to you, it is a tough, but rewarding journey. Remember, everytime you put food in your mouth you are eating to live!!
