Know Your Genes: TFAP2B “Protein Gene”

The Transcription factor AP 2 beta (TFAP2B) gene is associated with the synthesis of transcription factor AP 2 beta, which is associated with the stimulation of cell proliferation and in the destruction of cells (apoptosis).

Our ancestors consumed a diet that is believed to have been 35% high in fats, 35% from carbohydrates and 30% from proteins. People with certain variations of the TFAP2B are associated with a better response to high protein in the diet.

Association of Protein Intake and Weight Gain Tendency:

In a study conducted to identify a suitable diet for weight loss, a trial was conducted among 932 obese families. People with the A variant of the gene were shown to be associated with lower weight regain on a high protein diet (>5.4 points higher protein intake than the normal protein intake group) and low G.I carbohydrates group.

In another study, people with the G variant on a high protein diet gained 1.84 kg per risk allele, when compared to people with the AA genotype.

GG [Limitation] More likely to have higher weight regain on a high protein diet
  • Eat a balanced meal
AG Moderate weight regain on a high protein diet
AA [Advantage] More likely to have lower weight regain on a high protein diet
  • A high protein diet helps curb hunger
  • Protein rich food sources are seafood, cheese, soy, eggs, beans, nuts, seeds and meat
  • Choose protein sources that have nutritive value like salmon which is rich in omega 3 or beans which is rich in fibre.
