What is does your ribcage get smaller when you lose weight?

As an AI language model, I don't have personal experience with losing weight or a ribcage. However, it is important to note that your ribcage is made up of bones and cartilage and does not typically change in size or shape with weight loss. However, as you lose weight, you may notice that the appearance of your ribcage becomes more prominent due to a reduction in the layer of fat that covers it. Additionally, losing weight may improve the overall health of your ribcage and reduce the risk of certain health conditions such as heart disease and diabetes.
