Names, a packet of sweets is not the end of the world, slip ups will happen. It’s what you do after.
When my PT guided me ditching sugar it was a slow process, took several months. If your body is used to sugar fixes, it will crave them, it will drive you to gorge on sweet stuff. But you can trick it. Still have something sweet, but instead of bad bad refined sugar, it can be dried raisins and other dried fruit. Can be nuts, can be a piece of fruit. It will still be something sweet for you.
Unfortunately, it is impossible to be free from sugar cravings as long as you still consume refined sugar. It will soon spiral back.
What I found was I had to completely cut out rubbish, and I had a lot of dried fruit with my tea at first. But then I needed it less and less. To the point I can have a cup of tea on its own now and enjoy it.
Sugar is in every manufactured foodstuff, any shop bought sauces, bread, even things which supposedly are not sweet. It drives appetite to unnatural levels and makes us tired once the initial buzz is over. It sends insulin into overdrive and as long insulin is high, the body will not burn an ounce of fat.
Play it as a long game, it is an addiction, it will take persistence and time to conquer. But it will be so so worth it.
I do not enjoy shop bought cake/chocolates now and will happily pass them over. If I bake, I put a lot less sugar as I can’t stomach the ‘normal’ allowance. Best of all, hunger does not rule my life. Needs be, I will happily wait 2-3 hours even when hungry. It is not the same desperate hunger, it is tolerable.
It is liberating!
