"Reduce intake of ultra-processed foods that are produced using high-fructose-containing sweeteners like high fructose corn syrup," sports dietitian Rachel Fine, MS, RD, CDN, told POPSUGAR. "These processed sugars are concentrated in fructose, which in high amounts has been shown to promote visceral fat accumulation in the liver, leading to weight gain, inflammation, and related diseases like metabolic syndrome."
Although processed sugars are found in the typical culprits: cookies, candy, canned fruit, and soda, it's also found in frozen packaged food like frozen pizzas and frozen dinners. It best to avoid these types of packaged food altogether, but if you indulge, be sure to check the labels.
