How to Eat 3,000 Calories a Day

Many adults will gain weight eating 3,000 calories per day, which is beneficial, if you're underweight or trying to increase lean muscle mass. However, active adult men ages 19 to 35 require 3,000 calories daily just to maintain current healthy body weights, according to the Dietary Guidelines for Americans 2010. If a 3,000-calorie diet is appropriate for you, then following a meal plan will help you meet your daily caloric needs.

Breakdown of Calories

To achieve a 3,000-calorie daily allotment, eat often -- every few hours -- and choose nutritious, calorie-dense foods. Examples include nuts, seeds, nut butters, legumes, avocados, plant-based oils and dried fruits. The Dietary Guidelines for Americans 2010 sample 3,000-calorie meal plan contains 4 cups of veggies, 2.5 cups of fruits, 7 ounces from the protein foods group such as eggs, lean meat, poultry, seafood and soy products,10 ounces of grains, 3 cups of dairy foods, 10 teaspoons of oils and 459 extra calories from foods of your choice.

Protein and Dairy Portions

To eat 3,000 calories and meet your daily nutrient needs, choose a variety of healthy, protein-rich foods, including dairy products. A 1-ounce portion from the protein group equals one egg, 1.5 egg whites, 1 ounce of meat, fish or poultry, one-half ounce of nuts or seeds, 1 tablespoon of nut butter, one-fourth cup of legumes, one-half of a veggie burger or one-fourth cup of tofu. A portion from the dairy group equals 1 cup of milk, yogurt or soy milk, 2 cups of cottage cheese or 1.5 ounce of hard cheese.

Grains, Fruits, Veggies and Oils

To balance out your 3,000-calorie meal plan and add additional vitamins, minerals and fiber, choose nutrient-rich fruits, veggies, grains and oils. A 1-ounce portion from the grains group equals one slice of bread, 1 cup of ready-to-eat cereal or 1/2 cup of cooked rice, pasta or oatmeal. A cup of fruits equals 1 cup of fruit juice, 1 cup of fresh fruit or 1/2 cup of dried fruit.

A 1-teaspoon portion from the oils group equals 1 teaspoon of plant-based oil, 1 tablespoon of Italian salad dressing, 1.5 teaspoons of nut butter or 1/3 ounce of nuts or seeds.
