I still do Keto, I started in November 2016, by June 2017, I lost 5 stone, I did a strict version of it, my only fats for energy were cheese, butter, nuts and avocado.
It was really hard at for the first 3 months, suffered from sleepless nights and headaches.
I ate, fish, white meat and once a fortnight a big juicy steak.
I cut out bread, rice, pasta, potatoes, all fruit and certain vegetables.
One cup of tea a day and then only water.
I take multi vitamins, plus vitamin C & D.
I walked 5 miles a day as my daily exercise.
I have kept the weight off, still do Keto 5 days a week, the other 2 days days I have carbs but only a small amount and they are wholemeal apart from the potatoes.
I still walk five miles a day and feel good about myself.
