Hi Sandie
I use My Fitness Pal – free – on my laptop, many here use apps on their phones. MFP is great as you can play around with possible foods you might eat on a day, before you actually eat them – you can check balance of carbs/cals/protein are ok, and alter if needed.
I also spend some time making a recipe, weighing everything, noting it all down including number of portions etc, and entering it under My Foods on MFP. Time consuming when you first do it, but very handy after. I even do this with my breakfast Greek Yogurt, chopped nuts, seeds, chia seeds, flax and berry fruits.
Some people on here count calories, but most importantly most keep the carbs at a max of 50 to 60. Some just count carbs, and some only have 20/30 carbs per day. You’ve already cut down on your carbs which is a great idea to do it gradually. Not such a shock to the system. You will gradually find what’s best for you. The most important thing is you ave chosen to start this new way of life.
Good luck, you’ll get lots of support here x
