Phat - I have so been where you are! Have you spoken to your rheumatologist? I have destroyed my metabolism from going too low in calories, then going off a diet, eating normal or too many then back on a diet again. My metabolism is almost at shut down mode. I literally HAVE TO work out in order to get weight off. Not only that but I cannot go too low in calories.
I too have fibro and arthritis. Here is some information that may help. Your eating or lack of eating adds to your joint pain and being tired.
Your body needs a certain amount of calories to carry out vital functions. If it does not get those calories from the diet, it can start to break down its own tissues for energy. To figure out how many calories you need per day, multiply your ideal weight by 12 if you are not very active or 15 if you are active. To lose weight, aim to eat around 500 fewer calories per day than your body needs to maintain your weight. Eating less than that will lead to side effects.
Some side effects are minor in comparison to others and transitory. They can become more pronounced depending on how much you restrict your calories. Some symptoms of severe calorie restriction are weakness, fatigue, cold intolerance, irregular menstrual periods, dizziness, constipation and swelling of the hands and feet.
Gallstones are caused by going on a severe calorie-restricted diet and losing weight too quickly. Often, you will need to have surgery to remove your gallbladder if this happens. (Had mine removed) Gout, or a painful inflammation of the joints caused by high uric acid in the blood, can start or become worse from low-calorie dieting. Since you are not taking in the proper amounts of vitamins, proteins and electrolytes, you are at risk for malnutrition disorders and electrolyte imbalances. Sudden death is a very rare but possible side effect from extremely low-calorie dieting.
Low-calorie diets force your body to take energy from other sources. You are more likely to burn muscle than fat because your body needs protein. This lowers your metabolic rate and makes it more difficult to lose weight. You are also not likely to stay on this type of eating plan for long, and you will eventually go back to your normal eating patterns. All the weight will come back. Furthermore, the electrolyte imbalances will cause your body to leach calcium from your bones, potentially weakening them and leading to osteoporosis.
Hope this helps.
