In this closing lesson of Yale's Low-Cost, High-Nutrition Eating for Graduate and Professional Students course, Dr. Nate Wood addresses how to make healthy, budget-conscious eating habits durable over the long term rather than a short-lived effort. He shares strategies for maintaining a balanced diet as academic and financial pressures continue across a graduate or professional program. The lecture draws together the course's earlier lessons on nutrition basics, meal planning, grocery shopping, and cooking, framing sustainability as the final piece that keeps those practices in place season after season. It is aimed at students seeking lasting habits rather than a one-time fix.
