Whether corn starch leads to weight gain mainly depends on the amount consumed and the individual's level of physical activity.

As a source of carbohydrates, corn starch is not low in calories, containing approximately 370 kilocalories per 100 grams. Excessive consumption in daily diet without corresponding physical activity to burn off the calories may lead to weight gain.

Consuming corn starch in moderate amounts combined with appropriate physical activity generally does not cause weight gain. However, if intake exceeds the body's needs and is not balanced with sufficient exercise to burn these calories, the excess energy may be converted into stored fat, resulting in weight gain. Corn starch itself is not a direct cause of obesity. The key factor leading to obesity is whether total caloric intake balances with energy expenditure. A reasonable diet structure, moderate intake of corn starch, and regular physical exercise can help prevent weight-related issues caused by excessive calorie consumption.

To avoid weight gain from corn starch, it is recommended to control intake levels and combine this with appropriate exercise to maintain weight balance.
