When aiming to lose weight during menstruation, adhere to these principles:
1. Eat oatmeal for breakfast—either instant or cooked—paired with soy milk. You may also add an apple.
2. Eat a satisfying lunch: Focus on vegetables, consuming at least three types daily, and include moderate amounts of meat.Don't believe claims that eating less will make you hungry—you'll inevitably snack, rendering your efforts futile.
3. Eat lightly at dinner: Whole grains are ideal, as experts note they aid stomach motility and digestion (e.g., sweet potatoes, corn). Finish dinner by 4-5 PM.

Special Notes:
1. Increase intake of iron- and fiber-rich foods like spinach, kelp, dried small fish, raisins, cherries, apples, red dates, honey dates, red amaranth, whole wheat bread, brown rice, oats, and milk.
2. Avoid raw, cold foods, ice cream, or iced beverages.
4. Limit sweets like beverages, cakes, and candies. This prevents blood sugar fluctuations and alleviates menstrual discomfort.
5. Avoid caffeinated drinks: Coffee, tea, and similar beverages may heighten anxiety and restlessness.
