but at the same time i lost weight and became really weak, i mean it was really hard to work out, cuz my limbs hurt…
my limbs used hurt in the morning as well, just after i got up…
but after i reduced the intake of fiber…i gained my weight back, my limbs stoped hurting
BUT BAD BREATH AND BAD SKIN HAVE COME BACK!!!

I am eating lots of fresh vegetables. And lean protein with complex carbs. I have all the essential vitamins and nutrients.
I think you are lacking some important group of food. It is important to eat a well balanced diet, so that you will not experience all these problems.
I am on low carb, low fat, high fibre, high protein and a hour brisk walk 5 times a week, and I have lost 31lbs/14kg and gained better health. I am now maintaining my 108lbs/49kg for more than a year, with more fruits and complex carbs.
Details such as my experience, meals, recipes, foods to buy, reading labels, walking as an exercise and to shape the body etc etc, are in my blog.

i think you have to consult a nutritionist about your diet. try vegetables and drink lots of water. if you are having difficulty on your workout try the simplest form…walking, or try this
