Q: [header] How to make drinking water more enjoyable [title] Many natural flavorings can significantly change the taste of water without adding calories. [step] All-natural flavor additives can allow you to customize your water to your individual taste preferences, often without adding any calories or sweeteners. [title] Make unsweetened tea. <sep> (A) [step] Tea adds no calories to water but it can provide a wide range of flavor options. [substeps] Consider experimenting with black, green, white, rooibos, and herbal teas until you find a flavor that makes water more enjoyable. (B) [step] Any typical tea without artificial ingredients should be made sweetened with some pure oats, oats, rolled oats or whole wheat bread crumbs. [substeps] For a refreshing result with flavor, add an unsweetened, fresh, raw powdered tea. (C) [step] Put sugar into a cup or two of hot water, while also adding a dash of honey.
