每行一项食物：可以只写热量（如“米饭 200”），也可以写“名称, 蛋白质 g, 碳水 g, 脂肪 g”由宏量营养素换算热量（4/4/9 kcal/g）。加总整餐热量和三大营养素，给出供能比例，并与每日目标比较。也兼容用空格分隔的一串热量数字。本地处理。One food per line: either just calories (such as Rice 200) or Name, protein g, carbs g, fat g to work out calories from macros (4/4/9 kcal per gram). The meal total and macros are added up with the energy split and a comparison with your daily target. A plain list of calorie numbers separated by spaces still works. Processed locally.
