How to shrink the dangerous fat linked to heart disease and cancer in 12 weeks | Prof Jimmy Bell

Visceral fat, stored around vital organs, functions as a metabolically active organ rather than a passive energy reserve. This tissue significantly influences systemic inflammation, insulin sensitivity, and long-term health, often independently of total body weight. Individuals with a "thin on the outside, fat on the inside" (TOFI) profile may carry dangerous levels of visceral fat despite a normal BMI. Because fat composition directly reflects dietary intake—with saturated fats promoting worse metabolic outcomes than unsaturated ones—improving diet quality is essential. Furthermore, visceral fat is highly responsive to lifestyle changes; combining resistance training with a nutrient-dense diet can significantly reduce visceral fat and improve metabolic health within 12 weeks. Professor Jimmy Bell, an expert in molecular imaging and metabolism, emphasizes that building high-quality muscle through resistance exercise acts as a crucial counter-balance to the inflammatory risks posed by excess visceral fat.
