I recommend changing to a keto diet I had been on a keto diet years before it became popular. One of my clients had terminal cancer and at the time I knew nothing about cancer. I am not a scientist but a nearly 70 years old retired psychotherapist. So I started reading about what cancer was and I read a question that asked "What does cancer eat?" Unknown to me at the time, cancer cells need sugar to survive. So it got me thinking about my diet and the ever increasing weight of people in the western world. The world is getting fatter. My mum says she did not see fat people prior to, during and after world war 2. I started off with the atkins diet which was far too strict for me then I changed to keto and I felt great. However, In December 2021 I had a left side hemicolectomy, the left side of my bowel removed, old age strikes again. The surgeon recommended that I change from my keto diet to a vegetarian diet for two years until my bowel had repaired and settled back to normal. If having half a bowel removed can ever be normal. Since being on the vegetarian diet my weight has sky rocketed to 90kg. I have put on 9kg of weight in 20 months. Incredible what carbohydrates can do to your weight. After all Carbohydrates are sugar. I have never been over weight so weight for me was not the issue. My exercise regime has not changed in that time. I still walk 30 miles each week. I cannot wait to go bck on my keto diet. I maintained a weight of 81kg on keto for over 12 years and now I'm 90kg after changing to a vegetarian diet, that is not good.
