In this straightforward video from Chef Caleb, he breaks down BMI categories and their actual health implications beyond the standard labels: under 18.5 (underweight risks like weak immunity, low bone density, hormonal issues, and "skinny fat"); 18.5–24.9 ("normal" but can hide poor body composition or skinny-fat problems—muscle and lifestyle matter more); 25–29.9 (overweight label that often misflags muscular people while flagging real fat-related risks like rising blood pressure); 30–34.9 (Class 1 obesity with elevated diabetes, heart disease, and joint strain, but highly responsive to modest weight loss); 35–39.9 (Class 2 with daily function impacts and sharper risks); and 40+ (severe obesity straining the body across systems, often needing structured medical support). He stresses BMI is a rough tool—body composition, strength, waist size, and habits reveal the true picture—and encourages practical changes for better outcomes at any level.
