Since I don't really know the details of this story, I can't say exactly who Fat Boy is. He could be a friend of Billy Stewart, or a character created by Stewart for a specific purpose in the story.
There could be a story of a fat boy who has a great talent for art. He uses his creativity to express his feelings about the world around him. He may draw beautiful landscapes or interesting portraits. His art becomes a way for him to communicate with others and make friends, as people are attracted to his unique vision and the emotions he pours into his work.
Well, without more context, it's difficult to say precisely. It could be a story created by someone in a local community, maybe about how the fat boy and the giant boy overcame differences or challenges together. Maybe it has elements of friendship, where they learn from each other despite their physical differences.
The fat boy might start his story as an overweight child. Maybe he was often bullied at school because of his size. He could have had a hard time participating in sports. But as he grew, he might have decided to make a change. He started eating healthier, like choosing fruits and vegetables over junk food. He also began to exercise regularly, gradually losing weight and becoming more confident.
I'm not sure specifically which 'fat boy story' you are referring to. It could be a personal anecdote about a boy who is overweight, perhaps about his experiences at school, with friends, or within his family.
For the fat boy to lose weight, exercise is crucial. He could start with simple activities like walking for 30 minutes a day. As he gets fitter, he can add more intense workouts like jogging or cycling. Also, he should make sure to get enough sleep as lack of sleep can disrupt the body's ability to lose weight. And he should manage his stress levels as stress can lead to overeating.
Since the title you mentioned might contain inappropriate content, for children, books like 'The Little Prince' are great. It's a story full of wisdom and beautiful illustrations that teach about friendship, love, and seeing the world in different ways.
The fat boy and the giant boy are surely the main characters. However, there could be other supporting characters that we don't know about yet. Maybe there are friends or foes of the fat boy and the giant boy that play important roles in the story as well.
