Dear friend ..
Welcome to Health care magic ..
There is nothing to be worried about your protien diet .. Protein will cause you gain weight but it is not the cause for your weight gain .
I would suggest you some information to lose weight .
Avoid carbohydrates as it contains much calories that get stored in liver
and causes weight gain .
Avoid fatty foods / oil food stuffs as fats are not digested properly and it will make cholestrol
to go up and will lead to fat deposition in body .
Eat good food in morning and minimal at night .
Exercise regularly to burn extra calories that are stored in our body .
Drink plenty of fluids than solids .
This will help you to reduce weight without any side effects to body .
Calcium is good for bone strength .
Hope this information is useful to you .
Thanks & Take care .
