Intra-abdominal fat (fat around abdomen) appears to have a genetic link in the majority of cases. As many as 25-40 percent of cases of obesity may be due to genetic influence. Genes may affect the type of Basal Metabolic Rate we have. A lower-than-average BMR will lead to a tendency to gain weight. |
Appetite can be affected by hereditary factors.
Genes can affect the amount of fat and muscle in our body. This fat-muscle ratio has a direct effect on our BMR and thus on our weight.
Thermogenesis - the amount of energy we need to metabolize food - may be affected by our genes. This, too, is likely to affect our weight.
Thyroid function, which is responsible for hypothyroidism and hyperthyroidism - both of which influence our weight, may be affected by genetic factors.
