Dinner will be a salmon salad. Two of those thinner fillets of salmon, pan fried. Grilled tomatoes, ribbons of carrot, olives, beetroot, rocket, watercress, spinach, sweetcorn, cucumber, and some new potatoes.
No idea how much water I drink, but it's a lot. I must fill my bottle about 5 times a day. I workout about an hour and a half a day, yoga and cycling either outside or on a stationary bike.
