I want cut down on my sugar intake but the problem is i like eating sweets a lot. how to control my sugar intake?

You already know: Don't buy it to have it in the house. Displace sugar-eating experiences with other ones. Recognize that achieving goals is not easy, and own the responsibility.

Seek true food: Many times humans develop cravings when their nutritional needs are not being met. In nature, foods that are sweet or rich are laden with vitamins, minerals and phytonutrients. However in Western society, sweet and rich foods are vastly empty calories, devoid of nutrition. By seeking to eat true foods as occur in nature, especially whole plant-based foods, you will be satisfying your body's need.
