I wanted to reply to your post as I am currently calorie counting but feel like I am the only one who does it this "old-fashioned way" rather than some new-fangled diet way.
I had 8 stone to lose and have lost a little over a stone so far. So it is successful but I have to say I am currently feeling quite fed up as it is daunting to have to lose SO MUCH weight.
I worked out that my currently daily calories to maintain this weight is approx 2300 so I am limiting myself to around 1500 each day for a slow but steady weight loss.
I strictly weigh everything and basically keep a running total of calories on a bit of paper through the day.
I eat chocolate pretty much every day but make sure I allow for it in my calories. I eat sugar free jelly and have lots of coffee with sweetener and a splash of skimmed milk as they are basically no calorie options. I bulk out meals with plain steamed veg too.
I try and make sure that my lunch and dinner each have no more than 400 calories in them so this gives me plenty of calories for snacks through the day and in the evening when the kids are in bed.
Personally I think it is the best way to lose weight as you can eat anything and just make adjustments the rest of the day to factor in the calories of what you want. It is totally flexible. Some days I eat healthily all day and others I give in to temptation and have to save calories on the mean meals I have.
I am confident that I will lose the wieght eventually, and I wanted to do calorie counting as I think it is the most sustainable for the future. I have lost weight before and then put it all back on because the way I was eating wasn't a realistic way to live forever. But I can actually see myself counting calories forever as it gives me the freedom to chop and change, eat out, and do what i want as long as I think about the calories in everything. This feels less like "being on a diet" than juct changing how I eat and being careful, which is how I need to be forever.
Hope this helps, and good luck!
