Hi, I'm Mary one of the FitDay dietitians. If you eat 1800 calories per day, 200grams of carbohydrate is about 45% of your calories. As someone said earlier, it's different for everyone, but most recommendations say to keep your carbohydrates between 45 to 65% of your calories. Also, alcoholic beverages can get metabolized like a fat.
It's a good idea to limit sugar as much as you can. Sugar can sneak into some foods - look on labels for maltose or sucrose or other ingredients ending in "ose", high fructose corn syrup, honey, molasses, fruit juice concentrate. Food labels can be tricky when you look at the grams of sugar, as it can include the sugars from fruit (fructose) and milk (lactose). Ingredients are listed in descending order by weight so look at the list of ingredients and see sugars are one of the first few ingredients. Also, get as much fiber as you can - 14 grams per 1000 calories.
