Patients with obesity generally also have elevated blood lipids, elevated blood uric acid, and slightly high blood sugar. Therefore, regarding diet, it is crucial to strictly adhere to a standard of low salt, low fat, and low purine. Avoid eating fried foods and animal offal, and do not consume carbohydrate-rich foods and sugary drinks. Additionally, for patients with high uric acid levels, it is advised not to consume excessive seafood and rich broths. It is recommended to avoid eating late-night meals, fried foods, and grilled items. The foods that should be avoided by patients with obesity are mainly determined based on the levels of blood sugar, blood lipids, blood pressure, and blood uric acid.
