Weight loss linked to healthy eating not genetics
The amount and quality of food and not a persons genetics will lead to weight loss, a study has found.
It has been suggested that variations in genetic makeup make it easier for some people to lose weight than others on certain diets.
To test this theory researchers at Stanford University conducted a randomised control trial involving 609 overweight adults, who all underwent genetic and insulin testing before being randomly assigned to either a low-fat or low-carb diet for 12 months.
Gene analyses identified variations linked with how the body processes fats or carbohydrates. But weight loss averaged around 5kg to 6kg at follow-up regardless of genes, insulin levels or diet type.
What seemed to make a difference was healthy eating, researchers said.
Participants who ate the most vegetables and consumed the fewest processed foods, sugary drinks and unhealthy fats lost the most weight.
Participants had 22 health education classes during the study and were encouraged to be physically active but the focus was on what they ate.
They were advised to choose high-quality foods but were not given suggested calorie limits nor were they provided with specific foods. Results are based on what they reported eating.
Fat intake in the low-fat group averaged 57 grams during the study versus 87 grams beforehand, while carb intake in the low-carb group averaged 132 grams versus 247 grams previously.
Both groups reduced their daily calorie intake by an average of about 500 calories.
