In order to improve the taste of yogurt, sucrose and jam will be added in the production process to increase the calories contained in yogurt. Therefore, it is best to choose sugar-free skim yogurt during weight loss. If you can't accept the taste of this yogurt, you may wish to choose skim yogurt or sugar-free yogurt, which will have lower calories than ordinary yogurt.
