Even when subjects did not lose weight, their overall health improved considerably just by eating less sugar

A simple 10-day study of obese children showed that cutting sugar had significant impacts on their overall health, even without weight loss.

Obese children — currently an estimated third of the youth population in the United States — who reduce their sugar intake see improvements to their health after just 10 days, a new study says.

The research, published in the Obesity journal, found that children who cut back on sugar saw better results on their blood pressure and cholesterol, and other health markers — despite the fact that they barely lost weight or reduced their calorie intake.

During the study, 43 participants had their dietary sugar intake reduced from 28 percent to 10 percent and substituted with starch for nine days.

By the 10^{th} day, participants were noted as having improved metabolic health, even in those subjects that lost no weight at all. Among the most significant changes, researchers noted an average decrease of LDL cholesterol by 10 points, and blood pressure by five points. Triglycerides, which are fats that contribute to heart disease, fell an average of 33 points.

## Obesity and overweight

Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health.

Body mass index (BMI) is a simple index of weight-for-height that is commonly used to classify overweight and obesity in adults. It is defined as a person's weight in kilograms divided by the square of his height in meters (kg/m 2 ).

### Adults

For adults, WHO defines overweight and obesity as follows:

- overweight is a BMI greater than or equal to 25 and
- obesity is a BMI greater than or equal to 30.

BMI provides the most useful population-level measure of overweight and obesity as it is the same for both sexes and for all ages of adults. However, it should be considered a rough guide because it may not correspond to the same degree of fatness in different individuals.

For children, age needs to be considered when defining overweight and obesity.

### Children under 5 years of age

For children under 5 years of age:

- overweight is weight-for-height greater than 2 standard deviations above WHO Child Growth Standards median and
- obesity is weight-for-height greater than 3 standard deviations above the WHO Child Growth Standards median.

### Children aged between 5&ndash19 years

Overweight and obesity are defined as follows for children aged between 5&ndash19 years:

- overweight is BMI-for-age greater than 1 standard deviation above the WHO Growth Reference median and
- obesity is greater than 2 standard deviations above the WHO Growth Reference median.
