Hey everyone.. around three weeks ago i finally decided to make some serious changes. I have never been an active person but decided to start walking/ jogging. I have been gradually running and i now feel much fitter, have been doing this 4 times a week for around 45- mins to an hour and i have changed my eating habits .. no junk food and eating much healthier .. i weighed myself three weeks ago before i started this and have weighed myself today and i have gained 7 lbs ?? i am really confused, i thought by starting to make exercise part of my daily routine and eating right weight would start to come off but its the exact the opposite.. i feel like i have lost motivation to keep it up .. please help ?
