I did this - have lost 3 stone so far since around April. Will be happy with one stone more off.
I don't weigh or calorie count my food.
Also I don't weigh myself every day/week....maybe once every 6-8 weeks. For me it's less focus on the whole weight loss and more on the 'feel good factor' , that works.
Stopped eating anything with obvious sugar in it such as cakes, biscuits, chocolate etc. Don't keep ANY sweet food in the house.
Any sugar urges - I drank a glass of water.
Potatoes/rice/flour based items such as pies/bread - maybe once or twice a week at the most - and just small amounts.
I eat lots of veggies, meat, full fat cheese.
Do a fast 1-2 mile walk 3 times a week - with a long uphill section that i dreaded to start with, but can now run up it with ease.
Have dropped 3 clothes sizes. Am a lot fitter
Allow myself one sweet treat a week IF I want it - but now most things are too sweet for me, so rarely bother.
I never crave food and barely ever feel hungry now - whereas before I was forever nibbling/munching away.
Sample menu :
Breakfast - Home made meusli - oats/sunflower seeds/pumpkin seeds/ flaked almonds/sultanas/grated apple/ soya milk.
Lunch - toasted pitta with peanut butter/cherry tomatoes/cucumber
dinner - Chicken/cheesy mash carrots and turnip/ small baked potato.
