A 32-year-old man, after receiving health check results revealing high BMI, triglycerides, and cholesterol, embarked on a weight loss journey. He diligently exercised and reduced his intake of refined carbohydrates. Despite losing 7kg in a year, his cholesterol and triglyceride levels remained elevated. A physician discovered that his high consumption of fatty red meat was the culprit. Adjusting his protein sources by incorporating seafood, white meat, and plant-based options helped him achieve normal levels within three months.
