At fifty-nine years old, Thomas had developed a habit he never questioned. Every night after dinner, he searched the kitchen for something sweet or salty to enjoy before going to bed. Chips, cookies, and processed snacks had become part of his routine, even though he often woke up feeling tired and uncomfortable. One evening, while looking at his usual snacks, he decided he wanted a simple change. Instead of reaching for another bag of unhealthy food, he placed two bananas beside his bed.

Thomas did not expect much from the small decision. He only wanted a better option for his late-night cravings. However, after several weeks, he began noticing differences. He was no longer waking up feeling as heavy after midnight snacking, and he wondered if the simple fruit he had chosen was responsible. Then, after months of continuing the habit, he discovered a change that surprised him even more.
