These foods—notably vegetables, fruits, legumes, and whole grains—should supply about 20 to 35 grams of dietary fiber a day, depending on your calorie needs. (Aim for 14 grams of fiber for every 1,000 calories, as advised by the Dietary Guidelines for Americans.) Fiber slows the absorption of carbohydrates, so they have less effect on insulin and blood sugar, and it provides other health benefits. Try to fill three-quarters of your plate with produce, legumes, and whole grains—leaving only one-quarter for meat, poultry, or other protein sources.
Another condiment worth utilizing in place of sugary dressings and marinades is apple cider vinegar. According to a study published in Bioscience, Biotechnology, & Biochemistry, consuming apple cider vinegar each day can lead to weight loss, reduced belly fat, waist circumference, and lower blood triglycerides. More specifically, the study of obese Japanese participants found that those who consumed 1 tablespoon of ACV over a three month period lost 2.6 pounds, and those who consumed 2 tablespoons lost 3.7 pounds in the same time frame. Go ahead and toss a tablespoon or two of this calorie, fat, and sugar-free stuff in your next salad dressing, sauce, or smoothie.
For a 2,000-calorie daily diet, aim for 2½ cups of vegetables and 2 cups of fruit a day. If you consume more calories, aim for more produce; if you consume fewer calories, you can eat less. Include green, orange, red, blue/purple, and yellow vegetables and fruits. In addition to the fiber, the nutrients and phytochemicals in these foods may help protect against certain types of cancer and other diseases. Legumes, rich in fiber, can count as vegetables (though they have more calories than most vegetables). For more fiber, choose whole fruits over juice.
