Your diet isn't optimal for fat loss, it is better suited for a lean, active person maintaining his weight. Your body is likely very resistant to fat loss if you've been overweight most of your life. If this is the case, you have to eat a much more nutrient-dense diet (and I would recommend you read "Eat To Live" by Fuhrman).
Eat more leafy greens and non-starchy vegetables.
Eat only low-sugar fruit, especially if you eat as many servings as you claim. No watermelon, raisins, dates, or bananas.
Eat beans instead of animal products and grains.
I will leave the rest of the issues, including hypoglycemia, to Dr Fuhrman. Read these two pages:
