The one-size-fits-all approach which suggests that following the same health and diet plan could help everyone lose weight and lower chances of developing chronic diseases isn’t true, as per a new study.
The study offers proof that different people, in fact even identical twins, might respond back to same foods differently and suggests that we all need personalized diets.
For the study, the researchers had 1,100 UK and US adults, which included 240 twins for 2 weeks. They tracked the insulin, fat and blood sugar levels of every participant after they consumed pre-formulated meals such as glucose drinks and muffins. They also tested the microbes residing in their guts as well as monitored their exercise and sleep.
The findings showed that foods which increased the blood sugar levels of a participant or maintained his/her fat levels high for hours did not necessarily have similar effect on another participant eating next to him/her- even if it were twins. In fact, individuals showed varied responses to similar meals when they consumed them at different hours of the day. This shows that the nutrition facts solely can’t predict how a particular food would affect weight and health, said study co-investigator Tim Spector from King’s College London.
However, it does not mean that we should rely only on personalized dieting. For the time being, Spector says that we should continue following the nutrition facts which seem to be universal such as eating variety of plants and reducing processed food until further study.
The study was presented at the American Society of Nutrition conference on Monday.
