    Frequently asked questions

    Combining diabetes medications that target different aspects of glucose regulation—such as metformin to reduce liver glucose production and SGLT2 inhibitors to increase urinary glucose excretion—with tailored lifestyle strategies (a balanced, fiber-rich diet; at least 150 minutes of moderate aerobic exercise weekly; and weight management) stabilizes blood sugar, lowers HbA1c, and reduces long-term complications.

    Combination therapy integrates two or more glucose-lowering medications (for example, metformin plus a GLP-1 receptor agonist) alongside lifestyle interventions like diet and exercise to achieve synergistic effects on insulin sensitivity, post-meal glucose spikes, and weight control, optimizing glycemic management when monotherapy is insufficient.

    Adopting a whole-food, plant-predominant diet rich in nonstarchy vegetables, legumes, and whole grains improves insulin sensitivity and reduces postprandial glucose excursions; pairing this with daily moderate-intensity activities, strength training two to three times weekly, and stress-reduction techniques further lowers fasting and postprandial glucose, often leading to significant HbA1c improvements without increasing hypoglycemia risk.

    In early-stage type 2 diabetes, intensive lifestyle interventions emphasizing 7–10% weight loss and 150–300 minutes of moderate exercise weekly can match or exceed the glucose-lowering effects of first-line diabetes medications like metformin, though ongoing pharmacotherapy may become necessary as beta-cell function declines over time.

    Clinical trials such as the DiRECT study have shown that very low-calorie diets followed by sustained healthy eating can induce diabetes remission in nearly half of participants at one year; achieving and maintaining significant weight loss alongside continued lifestyle support is key to sustaining normoglycemia without medication. 

    It works best for diseases like type 2 diabetes, heart disease, and obesity. These conditions are strongly linked to daily habits. Lifestyle medicine targets root causes to promote long-term health improvements.

    The six core pillars include whole-food nutrition, regular physical activity, restorative sleep, stress management (such as mindfulness or relaxation techniques), avoidance of tobacco and excess alcohol, and fostering positive social connections.

    These encompass structured modifications in daily behaviors—adopting nutrient-dense diets, integrating aerobic and resistance exercise, prioritizing sleep hygiene, practicing mental well-being strategies, and eliminating harmful habits like smoking—to prevent or treat conditions such as diabetes, cardiovascular disease, and obesity.

    They enhance heart health, weight, blood pressure, and blood sugar. Additionally, they lessen the requirement for some drugs. These benefits contribute to a better quality of life and reduced healthcare costs.

    While pharmacotherapy is essential for achieving glycemic targets and managing acute fluctuations, lifestyle serves as the foundational pillar: without consistent healthy habits, medication alone cannot fully address insulin resistance, dyslipidemia, and associated comorbidities, making an integrated approach the standard of care for optimal outcomes.
