Eat regular meals. An irregular eating schedule will lower your energy levels, could affect your milk production in the long run, and does nothing for weight loss. Avoid processed foods as they are less nutritious and often contain chemical preservatives, artificial colouring, saturated fats, sugar, etc. Banish cakes, biscuits, pastries, and processed, canned or frozen food from your diet. They all contain sugar in some form or the other.
Sugar is the enemy in the battle of the bulge.
Cut down on tea, coffee and alcoholic beverages. Remember that while you should eat enough to sustain your energy levels and to breastfeed, you should also be losing weight gradually. So weigh yourself regularly to monitor your weight loss. Small amounts - depending on ideal body weight. Cheese, whipped cream, whole milk, ice cream, red meat, french fries, biscuits and cakes.
