The meal planning for white-collar women shall match their physical conditions and office work demands. As their work relies heavily on mental labor, the classic dietary principle applies: eat a full breakfast, a hearty lunch and a light dinner.

In terms of calorie distribution across three meals, breakfast should account for 30% of total daily food intake, lunch 40% and dinner 30%. Special attention should be paid to breakfast and dinner. Breakfast must contain sufficient high-quality protein such as milk, soybean milk or eggs. Protein replenishes nutrients consumed during brain cell metabolism and regulates excitability and inhibition of the cerebral cortex.

Most hours between dinner and the next morning are spent sleeping, with minimal energy consumption. Therefore, dinner should limit high-calorie foods including rice, noodles and greasy dishes. In contrast, more vegetables and fruits are recommended to supply adequate vitamins and minerals, which help white-collar women maintain a slim figure, stay mentally alert and think sharply.

Furthermore, regular mealtimes and balanced eating habits are essential. Medical experts suggest a 4–5 hour interval between two meals. Excessively long intervals trigger hunger and reduce stamina and work efficiency; overly short intervals deny digestive organs adequate rest, impairing appetite and gastrointestinal function. Never skip or delay meals due to heavy workload or weight-loss pursuits.

Women under high work pressure and chronic fatigue may take DHA supplements (commonly known as "brain gold"). DHA significantly boosts brain activity, improves memory and thinking capacity, and relieves fatigue. Overseas studies show that DHA intake by pregnant white-collar women helps enhance their children’s intelligence.

In addition, many white-collar women attend business banquets involving alcohol, which calls for extra attention to nutritional intake. Avoid selective eating or insufficient food at banquets. Moderate drinking is acceptable for social purposes, but excessive alcohol consumption should be avoided.
