I’m your height, also workout 5/6 days a week, and weigh 9 stone.
Today I ate:
Diced chicken, avocado, berries, coconut milk yoghurt, kombucha drink.
Mid morning: sweet potato crisps and a sachet of peanut butter
Lunch: Two tuna mayo wraps with cucumber and avocado
Dinner: Steak in butter, sweet potatoes and spinach.
Snack: four squares of dark chocolate, another coconut yoghurt and an apple
To be honest, I could probably stand to eat a bit more given how hard I work out, but I would want to down a giraffe and eat the thing raw on 1200-1500 calories.
You could either maintain your calorie intake and stick to just weights; or you could (and probably should) add in another five hundred calories of protein and good fats.
