Nutrient Ratio For Losing Weight

Fad diets often require people to reduce entire groups of nutrients, including fats or carbohydrates, to dangerous lows. However, losing weight without risking nutrient deficiencies requires a balance of carbohydrates, fats, proteins, minerals and vitamins. Base your weight-loss diet on moderate calorie consumption from a variety of nutrient-dense foods. Consult a physician or registered dietitian before making significant changes to your diet.

Recommendations

Carbohydrates, fats and proteins all play important and distinct roles in the body. A shortage of any of these macronutrients can create adverse health effects for the organs, blood sugar regulation and tissue and cell maintenance. The United States Department of Agriculture, which sets dietary guidelines for Americans, recommends adults obtain 45 percent to 65 percent of daily calories from carbohydrates, 20 percent to 35 percent from fat and about 10 percent to 15 percent from proteins. If you are on a 2,000-calorie daily diet to lose weight, this equates to 225 to 325 g of carbohydrates, 44 to 77 g of fat and 50 to 75 g of protein.

Energy Balance

Weight loss is an energy balance equation requiring 3,500 fewer calories consumed than expended. The key is to eat a total of 250 to 500 fewer total calories than you expend daily. Carbohydrates, fats and proteins all supply energy, with carbs and protein containing four calories per gram and fat supplying nine calories per gram. Keep daily fat intake on the lower end of the spectrum, at 20 percent of daily calories, and track your food consumption against calorie expenditure.

Approach

In the carbohydrate group, consume mostly whole grains like brown rice, whole wheat pasta, fruits and vegetables, which provide more fiber than refined grain products like white bread. Fiber helps create satiety and prevent the type of overeating that leads to weight gain; refined carbohydrates like cakes and donuts add a lot of calories without significant nutrition. From the protein group, choose mostly lean sources like legumes, white fish and poultry, which have fewer calories and aid in weight loss. Consume red meat and fatty cuts of meat sparingly. Choose heart-healthy fats such as nuts, seeds and seed oils.

Micronutrients

Cutting out entire food groups in order to lose weight can cause micronutrient deficiencies. Micronutrients, which include vitamins and minerals like calcium; iron; zinc; and vitamins C, A, D, and E do not supply calories but are still important for health. Choose nutrient-dense food sources like bell peppers, broccoli or oranges to obtain key vitamins and minerals for minimal calories to help with weight loss. Micronutrient needs vary due to age, sex and health status, but in general, most people can obtain adequate minerals and vitamins through a balanced diet.
