High Genetic Risk Score (GRS) Group
This group consists of individuals who are in the highest quartile of the genetic risk score (GRS) and will ingest one sugar drink (equal to 2 soft drinks) per day for 3 weeks. The GRS is computed by adding the number of alleles that increase the risk for liver lipogenesis or fatty liver. Sugar drink: A sugar drink made with 1.2 g/kg body weight of added sugar( 0.75g/kg body weight of fructose + 0.45g/kg body weight of glucose) and 24oz water
Low Genetic Risk Score (GRS) Group
This groups consists of individuals who are in the lowest quartile of the genetic risk score (GRS) and will ingest one sugar drink (equal to 2 soft drinks) per day for 3 weeks. The GRS is computed by adding the number of alleles that increase the risk for liver lipogenesis or fatty liver. Sugar drink: A sugar drink made with 1.2 g/kg body weight of added sugar( 0.75g/kg body weight of fructose + 0.45g/kg body weight of glucose) and 24oz water

Sugar drink: A sugar drink made with 1.2 g/kg body weight of added sugar( 0.75g/kg body weight of fructose + 0.45g/kg body weight of glucose) and 24oz water
Low GRS Group
n=7 Participants
This groups consists of individuals who are in the lowest quartile of the genetic risk score (GRS) and will ingest one sugar drink (equal to 2 soft drinks) per day for 3 weeks. The GRS is computed by adding the number of alleles that increase the risk for liver lipogenesis or fatty liver. Sugar drink: A sugar drink made with 1.2 g/kg body weight of added sugar( 0.75g/kg body weight of fructose + 0.45g/kg body weight of glucose) and 24oz water
Mean Change in Serum Concentrations of Liver Function Marker (Aspartate Transaminase-AST).
-1.91 IU/L
Standard Deviation 14.9
1.28 IU/L
Standard Deviation 2.8

SECONDARY outcome

Timeframe: between week 0 (Baseline) and week 3
