I've been sugar free for a little over 2 months, and I've lost around 6.5 kgs. There have definitely been a few weeks where I haven't lost weight and it's seemed to go up a little, but overall it's going down.
I for one refuse to count calories, and ever since counting points on weight watchers approximately 14 years ago, I've refused to do any diet that includes weighing food or counting kilojoules or calories or whatever. That being said, I have noticed there are quite a large number of people on these forums who need to do this for them to work out what they're doing, and that's their choice.
Since going sugar free, breakfast for me can be anything from scrambled eggs, omelettes, to porridge (with some frozen berries instead of sugar), toast with sugar free peanut butter, or more recently some cereals that I found that were sugar free. Prior to going sugar free, I could never have started a morning with cereal because I would have been starving by 9am, but now I'm ok, and can definitely eat less for breakfast than I would have previously. I have a coffee made on full milk after I get to work.
Morning tea is 1 piece of fruit and a cup of tea.
Lunch can be some type of protein with salad with home-made dressing (white or malt vinegar, olive oil, salad herbs, optional wholegrain mustard, lime or lemon juice), leftovers or ham, cheese, tomato and onion toasted sandwich on wholegrain bread. If I know I'm having bread at lunch, I'll never have it in the morning.
I'm really bad at remembering afternoon tea, I did have mixed macadamia and cashew nuts on my desk for a while, but nothing currently. If I get time, or need a pick me up through the afternoon slump I may have a cup of tea.
I find that if I snack when I get home, I can't eat dinner, so I rarely do this anymore. Dinner is easy, because unless you live on premade sauces, most things can be made from scratch sugar free. I could do anything from basic meat and steamed vegies (with a homemade cheese sauce if I want to dress it up) to a homemade indian curry, casserole, goulash, texan chillie beef etc. Sometimes I'll get pizza for a treat, Pizza Capers have a nutritional guide online, and a lot of their pizzas are really low in sugar, I especially like their Alfunghi, but I do have to be careful because it can be easy to overeat on these. Once I've eaten, I find I don't want anything again at all.
If I want something to drink other than coffee, tea, milk or water, I buy some mineral water and either drink it as is, or add some fresh squeezed lemon or lime juice. I truly detest the aspartame flavour so diet softdrinks are definitely out for me, and research shows that it makes you crave carbs anyway.
I know my food isn't perfect, I should be squeezing 1 more piece of fruit in there somewhere, but I think overall it's pretty good. Don't ask me how many calories it is :P.
