I quit sugar after a stint volunteering in a homeless shelter, where I saw how people were with sugar. I was horrified, so I went cold turkey! Some say that going to an abattoir means becoming an instant vegan, seeing zombies with sugar at three in the morning had a similar effect on me.

I don't see sugar as the root of all evil, the master of all addictions. However, it is easy to quit and, if you can do that, you can quit anything else, including addictive substances. The reason is that, if you are avoiding all added sugar, then you have to cook. It means no more processed food and an improvement to the metabolism.

However, the quit sugar idea does attract people that want to lose weight, which is a noble goal, but not the same thing as wanting to live an active life at a healthy weight.

This means that most people drawn to no sugar are on a keto diet with all that this entails. For the keto diet person all carbohydrates are the enemy, with fat and protein as the allowed macronutrients.

I was open to completely changing my diet as, until the eye-opening experience, I had always put employers or others first and not really thought a great deal about nutrition. My 'intellect' was more concerned with programming languages than what I should be stuffing my face with!

Knowing nothing about the subject, I did want to know why I felt so much better from giving up sugar. So I investigated diet and nutrition. I developed new habits including when shopping. I mostly buy vegetables and supplement vitamin B12. The experiment is going very well. I quit coffee and much else, to arrive independently at a 'whole food, plant based' diet, which is 'closet vegan'. I clung on to butter for quite a while, but cut that cord to reject a lot of the 'anti-carb' thinking that goes with the keto diet.

I don't eat a lot of 'evil carbs', as viewed by the fat eating keto people. This is because I usually have so many leafy greens, legumes and other vegetables that I just don't have the need for a plate full of rice, pasta or whatever else is 'evil carbs'.

The thing is that every calorie has to have nutrition, so sugar is 'empty calories' with no nutritional value. I seem to be fine without it, I can go cycling for all the daylight hours in the day and not need anything more than a few pieces of fruit and a sandwich made with the help of a bread machine.

I don't think that not eating sugar is that big a deal, but it can be a very useful stepping stone towards arriving at a sustainable lifestyle that is not a 'diet'.

Much of the 'science' regarding why sugar is allegedly bad is not as clear cut as it should be. I have heard all about 'fructose' and 'ketosis'. I have also learned a little bit about history and how we came to be living a pastoral life in the UK before the Romans arrived. There has always been conflict between the people that farm grains and the people that eat animal products, with an overlap between the two camps. This is why we have people insisting that full keto, whale blubber only, is the way to go, then we have people insistent on vegan as the way to go, with the majority being okay with 'everything in moderation'.

In conversation I have mentioned that I 'quit all processed food' and that does not seem to trigger anyone. I really did manage to quit everything I was addicted to, but I don't see sugar as an addiction, even though I ate it every day for decades.

I did take sugar for granted and I would eat things in front of the TV without truly savouring the taste. I can't quite remember what those sticky toffee puddings tasted like, or some chocolate bars that I had thousands of times. I would recommend quitting sugar, however, you must be open to the possibility that you really will want to quit for good, to be eating fruit out of choice, and to want herbs and spices rather than biscuits and chips in the supermarket. If you get a figure that you enjoy living in and see cancerous moles vanish on your skin, then it can be hard to want to go back to a diet that includes sugar. There are no upsides to it once you get the health gains.

Hence, before you quit sugar, compile a list of your favourite things and spend a solid month savouring them, as a farewell tour. Enjoy with the TV off, in that way, when you have gone past the point of turning back, you can remember what these things tasted like, to not miss them or wonder.

I always keep my receipts for my grocery shopping. I would not be full of shame if someone were to read them and try to mock my food choices. Everything is healthy.

I have not used my fridge or freezer with this experiment, so they are turned off at the wall. My food is always fresh. It turned out that everything in my fridge was just trying to kill me and vegetables prefer being outside the morgue that is the fridge. My food waste is almost zero, although I did throw half a turnip out recently. Even my recycling bin is getting to zero, that has not seen plastic in a very long time, glass jars are rare and even tins are getting rare.

Sometimes I think about quitting my peculiar lifestyle, to turn the fridge and freezer back on, to stock them with sticky toffee puddings, vast slabs of cheese and everything else laced with fat and sugar. I could toss the vegetables out and put ready made meals in the microwave, or frozen pizza in the oven.

I found that we put the horse before the cart with 'exercise'. I found that, get the nutrition right, and the physical activity comes naturally. But, playing devil's advocate, I think about going to fizzy drinks, sticky toffee puddings and beer. I could get man boobs and a beer gut, maybe with an extra chin or two. I would never need to spend twenty minutes chopping vegetables ever again, oh, it could be so easy!

But no, I am staying off the sugar. However, it is no big deal, I just live in a parallel universe of vegetables with no processed sugar or silly science about the evils of fructose. Sugar is not evil, I just prefer the whole food, plant based life as a 'closet vegan'.
