What are the implications for practitioners and the public?

“The findings from this research open the door for the possibility of a more customized dietary care plan for diabetes treatment,” said Sheri Gaw, RDN, CDCES, a registered dietitian, certified diabetes care and education specialist, and owner of The Plant Strong Dietitian, who was not involved in the study.

Fung also emphasized that this study’s findings could hold significant importance for dietary choices.

“Insulin can cause weight gain, and for most people, cutting refined carbs is a very good method of reducing insulin and provoking weight loss. But for some people, a low fat diet may be more effective,” he explained.

The study authors, on the other hand, proposed that protein-rich diets could benefit individuals with type 2 diabetes based on their findings. However, they emphasized the need for further research.

Ultimately, “traditional diabetes diets focus on controlling carbs, based on the well-established link between glucose and insulin secretion, specifically refined grains and sugar,” but this study suggests the need for personalized approaches based on individual insulin responses to different macronutrients, said Holland.

“The difference is largely genetically determined, as pointed out by the study,” Fung agreed.

To this point, Gaw said, “In the future, there may be genetic tests that a practitioner can use to determine a macronutrient ratio that is best for an individual’s insulin response.”

In the meantime, Holland advises individuals to follow current dietary guidelinesTrusted Source with a willingness to make adjustments. Work closely with your primary care physician or registered dietitian to identify the dietary patterns and lifestyle changes that best support your unique needs for maintaining healthy blood sugar levels and optimal health.
