More in news
- Results of different studies: The results of early studies from Harvard, Stanford and elsewhere were compelling: genetic differences seemed to predispose individuals to lose different amounts of weight on different types of diets.
- Lack of further research on studies: Subsequent research has failed to show any statistically significant difference in weight loss between overweight people who “eat right for their genotype” and those who do not.
- Individual metabolism:(1) The effect of genes on obesity has been hard to tease out; various studies put the figure at anywhere from 35% to 85%.(2) Nutritionists have long observed that no one weight-loss strategy works for everyone, and that individuals show striking differences in their responses to different diets.
