I'm 5'3 and around 8 stone, so around 20 for BMI. Typical day's calories would range from 1750-2000 depending on how much I have exercised.
Usually something like:
B: Toast and marmite, then full-fat greek yoghurt with berries, oats and flax seed
L: usually leftovers, if not it's something like smoked salmon, scrambled egg and salady bits like beetroot, avocado, cucumber etc.
D: varies lots but lots of vegetables and pulses. I don't eat meat but do eat fish. Stuff like chickpea curry, bean and sweet potato enchiladas, salmon with roasted potatoes and vegetables, falafel and salad, shrimp stir fry.
Snacks- nuts, dried fruit, dark chocolate. Sometimes I have a banana and peanut butter milkshake after I workout.
Drinks- no alcohol, black coffee, herbal tea, water and sparkling water.
