Studies have also shown a link between high sugar intake and increased abdominal fat. But as Healthline.com points out, you should realize belly fat doesn't just come from refined sugars. Even natural or "healthier" sugars (such as honey) should be limited. Cutting back on your sugar intake is a simple way to lose belly fat without exercising or burning calories.
Salt, in moderation, is a good thing—the mineral is necessary for a healthy heart and brain. But too much salt and you’ll retain water, bloating up like a water balloon. Cutting salt is one of the primary ways to drop extra water weight (one reason you may see a big weight loss when starting a new diet!). Move the salt shaker off your table so you’ll get out of the habit of routinely salting all your food. Then if you taste your food and still really want salt you can still stand up and get some.
