I concentrated on calories, but as I wanted to eat a reasonable amount it sorted itself out into lower carb anyway. Typical day:
Breakfast, porridge with semi skimmed milk, 80 gm frozen fruit stirred in, cinnamon on top. Coffee
Lunch, sandwich, wholemeal bread, low(er) fat cheese or lean meat, salad veg from the garden - tomatoes, various leafy greens. Coffee.
Dinner. Baked fish, variety of veg from garden, new potatoes, runners, tomatoes, broad beans, onion. Whatever's in season, potatoes, tomatoes, onions baked alongside fish.
If I'm really knackered, a couple of eggs on toast. Poached.
No snacks really, maybe an apple or a couple of oatcakes.
I usually walk 4-5 miles a night with the dog. Use Endomondo app on my phone to track distance and calories burned. I'm walking in the woods and it's a great de-stresser after work.
It's worked for me. 20lb off and it just feels like normal life, not depriving myself. My fitness pal is good because it helps you get your portion sizes down. You realise just how much you were eating and how much exercise it will take to burn it off.
So although I'm mid fifties and peri menopausal in feel and look better than I have in years.
