You may be doing too much exercise.
You also will find spot reductrion is nigh on impossible. Someone came on here about 3 years ago and said it is in a hormonal way and I've heard it supposedly works with giant sets, but to be honest if it is possible, it's hard and you probably will fail to do it.
Lack of protein could potentially cause weight gain. If you changed your diet and ate less Protein you could find you can't sustain your muscle mass, burning a bit off and as muscle burns calories, so losing some reduces caloric burning potential, meaning you could store more calories as fat.
Melatonin is a substance in the body that can help with natural skin tanning and the natural colour of hair, as opposed to having grey hair. I believe it is affected by Copper intake for one thing, so these things may be linked to pale skin if so, Copper is in things like Beans, Rice, Shellfish, (I think), Mushrooms, pork, nuts, green veggies etc, so consider some of your food choices and perhaps amend slightly, as you may possibly be undereating a bit, so if my supposition about the pale skin is right, you might need more copper in your diet.
