Helps you lose weight: Brown sugar has fewer calories than white sugar. The molasses in brown sugar is known to stimulate metabolism. Therefore, it can be said that brown sugar helps you lose weight. Because it's low in calories, brown sugar doesn't cause you to gain weight like white sugar.
Therefore, you can consume dishes prepared with brown sugar. But, since this is also a type of sugar, it's best to limit your intake to stay healthy and fit. Marketing tricks, if done right, can make strange things catch on. Just because brown sugar is marketed to be healthy, don't think it really is.
Your purchase decisions should be based on scientific evidence and not on advertisements. If candies and desserts aren't a regular part of your day, you can eat brown or even white sugar. As long as your consumption remains moderate, it will help you live healthy and even support weight loss. There are few studies that demonstrate the benefits of brown sugar on its own.
However, as an additive, brown sugar offers several health benefits by providing energy to people and acting as a flavor enhancer to promote healthier eating. To improve weight loss, a food product must have a lower calorie density. Sorry to have burst your bubble, but both brown and white sugar have nearly the same caloric density. People make brown sugar by mixing white sugar with molasses, which gives it a different flavor and a different nutritional composition.
While brown sugar can help you sweeten healthy foods you wouldn't otherwise enjoy, keep in mind that a healthy serving of brown sugar is quite small. However, if you extract sugar from it, then it has (surprise surprise) the same caloric density as sugar.
