+# Model description
+
+This model is a decision tree classifier trained to predict obesity levels based on demographic, lifestyle, and diet-related features. The dataset includes variables including age, height, weight, caloric food intake, physical activity, water consumption, smoking behavior, and transportation habits. The target label is the obesity category, which includes seven classes ranging from Insufficient_Weight to Obesity_Type_III. The decision tree originally had 12 layers which was cut down (pruned) to improve interpretability and reduce overfitting.

+
+# Intended uses & limitations
+
+**Intended use:** Educational use, possible tool for exploring health data, research, and classification and interpretability techniques. The model performs very well for higher risk categories.
+
+**Not intended for:** Actual medical diagnosis or treatment decisions.
+
+**Limitations:** Normal-weight and neighboring overweight classes overlap, making them harder to classify. The data is also self-reported, whichmay lead to bias or inaccuracies.
+
+# Evaluation Results
+
+The model achieves approximately 87% accuracy. Its performance is strongest on more distinct obesity categories and weaker on categories that are closer together. A more complex model could lead to higher accuracy, but it would be less interpretable and harder to present to medical professionals.
