I did 5:2 for a few months a few years ago with success, and have not usually eaten breakfast since. I have often been low-carb. I did a home-made version of the 5 day Prolon fasting-mimicking diet in February 2018, which gave me much better appetite control, and reading the forum posts here, realised I could manage 5:2 with just one evening meal, and from that, have been trialling 19-5 giving me the opportunity to enjoy my food once a day and eat with the family at supper. I use myfitness pal to track my weight daily, and my food sometimes.
I do hope that the small amount of milk I have in one morning coffee and one lunch time cup of tea do not affect the fasting process too much. Currently 69 kg, 1.6 m, BMI 26.9. I'm aiming to lose 6 kg to reach normal BMI.
