I started a few weeks ago with a new diet and exercise routine and am getting very fustrated. I am very overweight(237lbs- 5'2") and I should be losing weight a little faster in the beginning versus someone thinner, but I am not. I am eating very well, lean protein, veggies....lots of water. I am also exercising by doing my stationary bike 30 mins. 4 times a week, Walking 1 hour everyday, and also doing some lunges/squats and arm exercises with weights. I lost a couple pounds at first within the first week which was probably mostly water weight. But now I'm going the opposite weight. I started out at 241, went to 236.5 and then now I'm back to 239lbs. I weigh myself at the same time (first thing in the morning). What is going on? I know most people are going to say that its muscle, but is that true, could I be gaining that much muscle in just what im doing? I also haven't noticed any inches lost either. Should I be taking a day off, I haven't taken a day off since I started and wonder if that could have an effect. Please let me know your advice and what i can do. It's fustrating because you see people my weight and there dropping weight like nothing, why am I not.
