Ketchup
Although you might think that ketchup is a healthy topping, it's best to limit how much you are eating. According to Healthline, "The tomatoes in ketchup are so diluted by sugar and salt that they offer no nutritional value."
Barbecue Sauce
Barbecue sauce is another condiment you should limit, especially if you are trying to lose weight. According to the Food Network, "Popular sauces average anywhere from 45 to 70 calories for a two-tablespoon serving. You’ll also find a hefty amount of sugar, about 12 to 17 grams per serving, plus 200 to 350 milligrams of sodium; that’s as high as 14 percent of your daily allotment."
Mayonnaise
Mayonnaise is high in fat and calories, which makes it a bad choice of condiment if you are hoping to lose weight. Keeping your mayonnaise intake in moderation is definitely a good idea if you are hoping to keep an eye on how many calories and how much fat you are eating.
Soy Sauce
Soy sauce is full of salt, so you should definitely only have it in moderation. According to Health, "A single tablespoon contains over 900 mg, which is more than a third of the maximum recommended daily limit for healthy adults (2300 mg)."
