Hi dear,  I understand your concern about your health. I  agree with Dr. Jain in terms of your queries. I would like to add on few points like if you are having large intestine ulcers then you need to be very careful about you bowel movements. When you are on high protein diet, body has a tendency to increase constipation. Hence there should be optimum balance between intake of fluids, fibers and proteins. If you can, then please consult a diet consultant n tell your condition to customize your diet pattern carefully. It is recommended for your well being. You can consult me online or any one near your location.

Hello there.  I can understand your concern.  You can take a high protein diet and that will be enough for workouts unless you want to build muscles and go for body building competitions.  Power will come gradually. Dont expect power soon. Yes you can take green tea with honey or even sugar free. It will surely give its benefits. You must avoid oily, spicy and tea/coffeeand other carbonated drinks. Consult a general physician in person for further evaluation and management.  Best regards. Dr. Anil kumar jain. Bangalore.
