Diet is restricted but analyze: am I creating nutrient deficiencies? Map diet for potential deficiencies: iron, B12, vitamin D, omega-3. Calculate: if deficiencies affect energy and metabolism, what's the weight loss impact? Show me the nutrient gaps: these might be deficient in my diet. Give me the supplementation strategy: test these, supplement if needed. Include: whether deficiencies are causing fatigue affecting activity, what to test, and how deficiencies affect weight loss.
