Make it yourself. Make all of your food yourself. My regular gym routine, which was part of my life for years until a few months ago when I was forced to stop, involved lifting heavy weights followed shortly afterwards by a bowl of porridge. It's a big bowl of porridge and I would put about 2 tsp of sugar in it to sweeten it. I considered this sweet because it was, in fact, the only sugar I was consuming. Now since lockdown I've had to stop my porridge because my muscle was becoming replaced with fat. I've had to lose weight to stay lean. But I've replaced that small amount of sugar I had regularly with other sweet things and noticed that I'm consuming far more sugar now. I've decided to stop completely now. If you consume ready-made things with sugar, it very quickly becomes an addiction.
