Background:
Hyperinsulinemia (HI) is a common endocrine metabolic disorder in obesity and is closely associated with cardiovascular disease.
Aim:
This study aims to investigate the effects of progressive weight reduction on HI and cardiovascular risk factors.
Methods:
We enrolled 68 patients with overweight or obesity. Body composition assessments, clinical indicator sampling and a 75g-oral glucose tolerance test were conducted at baseline and after 12-month weight loss to assess HI and insulin sensitivity. And the people were divided into four groups based on the percent of weight loss (<10%, ~20%, ~30%, >30%) to study the remission of HI and changes in body composition and cardiovascular risk factors.
Results:
A total of 66 participants were studied at the end. Progressive weight loss significantly reduced plasma glucose and insulin (P<0.001, P <0.001) and did not progressively reduce cardiovascular risk factors (P <0.001). The greater the percentage of weight loss, the greater the remission rate of insulin resistance and hyperinsulinemia (P <0.001), which reaches 100% when weight loss exceeds 30%. After adjusting for factors such as age, gender, and medication usage, remission of HI was still associated with progressive weight loss.
Conclusion:
With progressive weight loss, people with overweight or obesity experienced further improvements in glycemic outcomes, body compositions, HI and insulin resistance.

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
