QUESTION: I am 57 and have fasting glucose of 165.9 mg/dL, post-meal glucose of 207.7 mg/dL, and HbA1c of 7.8%. My triglycerides are 190.9 mg/dL and HDL is 36.7 mg/dL. I take metformin SR 500 mg, losartan with hydrochlorothiazide, atorvastatin, aspirin, and vitamins. I follow a vegetarian diet. What is an ideal diabetes diet, and are there safe natural remedies?
Your fasting glucose, post-meal glucose, and HbA1c are above the usual targets for many adults with type 2 diabetes. A vegetarian diet can be very healthy, but it can still raise glucose if portions of rice, roti, potatoes, sweets, juice, or refined flour are too large. Arrange a medication and nutrition review rather than relying on herbs. Cinnamon, bitter melon, fenugreek, gymnema, and supplements are not proven substitutes for diabetes treatment and may cause side effects or interactions.

Hello Dr. Jani,
Your results suggest that diabetes control needs improvement, although they are not an emergency by themselves. The safest plan combines structured meals, activity, monitoring, and medication adjustment when needed.
Using the standard conversion, HbA1c of 7.8% corresponds to estimated average glucose of about 177 mg/dL. Ask how the laboratory calculated the reported 200.38 mg/dL. Our guide to HbA1c and estimated average glucose explains the difference.
For most main meals, aim for:
Being vegetarian does not automatically mean that a meal is low in carbohydrate. Large portions of rice, roti, naan, idli, dosa, potatoes, sweets, sweetened tea, fruit juice, and fried snacks can raise glucose. Our guide to carbohydrates and glycemic index can help you compare portions and food quality.
Choose whole fruit rather than juice, drink water or unsweetened beverages, and use nuts, seeds, avocado, and vegetable oils in modest portions. Limit sweets, sugary drinks, refined grains, trans fat, and frequent fried foods. A dietitian familiar with Indian vegetarian meals can tailor portions to your weight, activity, kidney function, and treatment.
No herb has been proven to replace metformin or other prescribed treatment. Bitter melon, cinnamon, fenugreek, garlic, and gymnema may produce inconsistent effects, interact with medicines, or cause an unwanted fall in glucose. Product strength and purity also vary.
Normal culinary amounts may be used as foods or spices unless your clinician has advised otherwise, but concentrated powders, extracts, teas, or capsules should not be started as diabetes therapy. Read more about supplement safety in diabetes.
If your doctor considers exercise safe, gradually work toward at least 150 minutes of moderate aerobic activity each week, spread over at least three days. Brisk walking is a suitable starting point. Add resistance exercise two or three times weekly and break up long periods of sitting.
A short walk after meals may help reduce post-meal glucose. Start gradually rather than doing occasional intense exercise. Our exercise and diabetes guide explains practical precautions.
Because HbA1c remains 7.8% while taking metformin, arrange a review with your prescribing doctor. Your clinician should assess adherence, meals, kidney and liver function, side effects, and whether treatment should change. Do not increase metformin or add another medicine yourself.
Also ask for a full cardiovascular review, including blood pressure, fasting lipid profile, smoking status, weight, and the reason for aspirin treatment. Do not stop losartan, hydrochlorothiazide, atorvastatin, aspirin, or any other prescribed medicine without medical advice.
No. Urine glucose mainly indicates that blood glucose exceeded the kidney’s glucose threshold at some point; it does not measure kidney damage. Diabetes kidney screening should include a serum creatinine-based estimated GFR and a spot urine albumin-to-creatinine ratio. Learn more about diabetes and kidney screening.
Seek prompt medical advice if glucose remains around 300 mg/dL or higher, especially with excessive thirst, frequent urination, weakness, dehydration, or weight loss. Seek emergency care for readings above 400 mg/dL, confusion, repeated vomiting, abdominal pain, difficult breathing, fainting, or inability to keep fluids down.
Your main priorities are improving glucose control, lowering triglycerides, protecting cardiovascular and kidney health, and making the vegetarian diet more structured. Medication adjustment may be necessary even when diet and exercise are excellent. Ask about vitamin B12 monitoring because both long-term metformin use and a strict vegetarian diet can increase the risk of deficiency.
