Dr. Jaiwant Rangi argues clinicians should test, not guess, when managing metabolic health. He recommends assessing diet for red flags like low dairy intake or vegetarian patterns, then measuring vitamin D, B12, magnesium, fasting insulin, and inflammatory markers to guide targeted treatment instead of relying on symptoms.

My approach is simple. We test, don't guess. I don't recommend supplements based on symptoms alone. I measure. And here's my framework. What do I do? First, I assess the dietary patterns. Look at person is vegetarian. They have risk for B12 deficiency. Are they low in dairy? Risk for vitamin D and calcium. Are they drinking too much alcohol? That might affect your vitamin B and folate. And sometimes these people end up getting more neuropathy and symptoms like that. So you definitely want the dietary pattern assessment. Second, I measure the key biomarkers. For metabolic patients, I routinely check their vitamin D. Vitamin B12, magnesium, their fasting insulin, their inflammatory markers, you know, things that help me understand what can I expect and what to replace.
