Re: Getting fatter but not gaining weight
It is very likely that you are indeed losing muscle and gaining fat. Muscle weighs more than fat so what you are experiencing is indicative of your muscle / fat ratio heading in the wrong direction.
In your situation, it is actually obvious to see what you need to do, although, most people do not really understand what is going on inside the body in similar scenarios. Believe it or not, your problem is directly related to insulin resistance, fat storage because of your diet, and your body metabolizing muscle for energy rather than fat.
To understand this, I recommend you read a book called "Protein Power". This explains the whole thing, although, it is pretty technical and will take some dedication to study and understand this fully.
To make a long complicated story super short: You have a broken metabolism and need to get your insulin working for you again. To do this, you need to cut carbohydrates out of your diet - bread, pretzels, pasta, potatoes, and other foods that spike your insulin. Calories do not make a bit of difference for you right now and won't until your body starts to function normally again. Eat lean protein and vegetables exclusively with plenty of water for four weeks and see what happens. I know that if you stick to this, you will be amazed by the results.
Be aware: if you suddenly stop eating carbs you will probably feel lousy for a few days with headaches. This is a sign that things are getting BETTER not that there is something WRONG happening. Quitting carbs is like quitting smoking - it is like breaking an addiction. You must get through this phase or continue down the path to Type II Diabetes and other degenerative diseases that will reduce the quality and length of your life.
Just my $0.02 - I wish you the best of luck and hope you get started turning this around for yourself immediately.
