If you are on our Man/Woman plan (TFRD) simply follow the guidelines for our Man/Woman with meal plan (VLCD diet) for the evening.
Choose foods that are high in protein and low in carbs, such as chicken or fish, and try and choose meals that you know have been baked or grilled rather than fried. Again, eating plenty of green vegetables is key to keeping calories down.
Ask to have any sauces replaced with low-calorie varieties if they have them, or ask to have them removed entirely. Resist the urge to have a glass of alcohol and choose water instead!
