There have been 3 to 5 times in my life that I've been so angry that I have switched off. I see only red air around me . Anyone know what this is? I've been heading to the gym for the last 15 days and I workout rigorously for 2.5 hours and I have lost only one kg. I don't know what to eat to follow a strict diet. What can I do so that I can lose 4-5 kg per month?
