Do you generally eat well but indulge sparingly? yep, exactly this! Do tend to cook from fresh and avoid processed food/low fat stuff as much as possible, but really your sentence nails it. Plenty of time on your feet/moving your body helps too, I think.
My BMI is 19. I’m breastfeeding so eating extra. Today I ate...
Breakfast: Small croissant with homemade marmalade, banana, coffee with whole milk. (Would normally have muesli, yoghurt and fruit but was staying with friends so pastries for a treat)
Mid morning: 2 pyclets with yoghurt and raspberries, latte
Lunch: slice of toast, 2 scrambled eggs, handful of cherry tomatoes, apple
Mid afternoon: herbal tea, Portuguese custard tart
Late afternoon: small glass of wine and packet of scampi fries in the pub
Dinner: aubergine gratin, boiled new potatoes, steamed chard.
