Gene-nutrient interactions and susceptibility to human obesity

Area of Science:

• Genetics
• Metabolic Diseases
• Nutritional Science

Background:

• Genome-wide association studies (GWAS) and candidate gene studies have identified numerous gene variants linked to common human obesity.
• Evidence indicates these obesity-associated gene variants interact with environmental factors, influencing susceptibility to this complex metabolic disease.

Purpose of the Study:

• To review current knowledge on energy balance, body weight heritability, gene variant origins, and gene-nutrient interactions relevant to human obesity.
• To provide insights for developing targeted nutritional and medicinal therapies for obesity prevention.

Main Methods:

• Review of existing literature from genome-wide association studies, transferability studies, and candidate gene studies.
• Synthesis of information on energy balance, heritability, gene variant origins, and gene-nutrient interactions.

Main Results:

• Identification of multiple gene variants associated with common human obesity across diverse populations.
• Recognition of the significant role of gene-environment interactions in obesity susceptibility.
• Highlighting the importance of gene-nutrient interactions in the context of obesity.

Conclusions:

• Understanding the genetic basis of obesity, including gene-environment and gene-nutrient interactions, is crucial.
• This knowledge can guide the development of personalized lifestyle interventions, nutritional strategies, and medicinal therapies for obesity management and prevention.
