Metabolically healthy obese individuals: Key protective factors

Area of Science:

• Endocrinology
• Metabolic Health
• Obesity Research

Background:

• Obesity is a major health issue impacting quality of life.
• Metabolically healthy obesity (MHO) describes obese individuals with normal metabolic profiles.
• The factors protecting MHO individuals remain poorly understood.

Purpose of the Study:

• To review factors associated with uncomplicated severe obesity.
• To identify mechanisms by which MHO individuals avoid metabolic complications.
• To explore the long-term prognosis of MHO.

Main Methods:

• PubMed database search.
• Keywords: Metabolically healthy obese, insulin resistance, uncomplicated obesity.
• Literature review of factors in MHO.

Main Results:

• Reviewed factors contributing to severe obesity without complications.
• Identified potential mechanisms for metabolic protection in MHO.
• Highlighted the lack of understanding regarding MHO's long-term outcomes.

Conclusions:

• Visceral fat is key to insulin resistance and cardiovascular risk.
• It is unknown if MHO has genetic factors or if it progresses to metabolic syndrome.
• Prophylactic bariatric surgery may be considered for MHO.
