Core Viewpoint - The claim that consuming more alkaline foods leads to faster weight loss is misleading, as the body's acid-base balance is primarily regulated by its own buffering systems rather than dietary intake [1][2] Group 1: Food Classification - Foods are classified as acidic or alkaline based on the residues they produce after metabolism, not their taste or pH value [1] - High-protein foods (meat, eggs) and high-starch foods (rice, wheat) tend to produce acidic residues, while fruits, vegetables, and dairy produce alkaline residues [1] Group 2: Weight Loss Principles - The fundamental principle of weight loss is energy balance, where energy intake must be less than energy expenditure [1] - Although many alkaline foods are low in calories, improper consumption methods (e.g., frying or excessive starch intake) can lead to excessive calorie intake, hindering weight loss [1][2] Group 3: Nutritional Advice - Long-term reliance on alkaline foods alone may result in nutritional deficiencies; a balanced diet including animal products is essential for comprehensive nutrition [2] - The 2022 Dietary Guidelines for Chinese Residents emphasize the importance of energy balance through food intake and physical activity, recommending diverse food consumption and mindful eating practices [2]
