To keep your energy levels up, eat five or six small meals a day instead of three large meals. Avoid skipping meals. Try to snack healthily. Eat vegetable sticks, low-fat smoothies, fresh fruit, yogurt, dried fruit and nuts. Eat plenty of fruit and vegetables. Include lots of wholegrain breads and cereals in your diet - about six servings a day. Increase your intake of calcium by including low-fat dairy produce, nuts or wholegrain foods in two or three servings a day. An extra 16g of protein a day is needed during the first six months of lactation. Good sources are lean meats, chicken, oily fish, eggs, nuts and pulses. Avoid alcohol and coffee, as they can pass quickly into the breast milk. Drink about two litres a day of fluids, as this will help with milk production. Eastern promise How do Chinese delicacies traditionally taken postpartum affect your health and weightloss efforts? Daphne Wu, dietician-in-charge at Matilda International Hospital, gives her diagnosis. Korean or Changbaishan ginseng claims to improve blood circulation, but it may actually hinder the wound healing if taken too soon after delivery. Swallow's nest will depend on the preparation - after double steaming, rock sugar and chicken fat can add extra calories. If the portion of bird's nest is small, the energy level will be negligible, so don't overindulge. Sweet vinegar with pig's feet, boiled egg and aged ginger are traditionally served to friends and relatives 12 days after the birth. The ginger is said to improve the mother's circulation, while the trotter and eggs are good sources of protein. The skin of the trotter contains collagen which is good for wound-healing, and the sweet vinegar is energising.
