Benefits, Weight Gain, and Meal Plan


A 2,000-calorie diet is considered standard and meets the nutritional needs of most people.

However, depending on your activity level, body size, and goals, you may need more.

This article discusses everything you need to know about a 3,000-calorie diet, including reasons for following one, what foods to eat and limit, and a sample meal plan.

Your daily calorie needs are based on several factors, including:

  • Gender. Women generally burn 5–10% fewer calories at rest than men of the same height (1).
  • Age. The number of calories you burn at rest declines with age (2).
  • Height. The taller you are, the more calories you need to maintain your weight.
  • Activity. Exercise and activities like yard work and fidgeting increase calorie needs (3).

Daily calorie needs range from 1,600–2,400 calories per day for adult women and 2,000–3,000 calories for adult men, with the low ends of the ranges being for sedentary people and the high ends for those who are active (4).

These estimates are based on equations using an average height and healthy weight for adult women and men. The reference woman is 5’4” (163 cm) tall and weighs 126 pounds (57.3 kg), whereas the reference man is 5’10” (178 cm) and weighs 154 pounds (70 kg).

Depending on your body size and activity level, you could require 3,000 calories or more per day to maintain your body weight.

Though athletes generally have higher calorie needs than the general public, people with physically demanding jobs, such as farm laborers and construction workers, may also need a high number of calories to maintain their weight.

Conversely, if you perform moderate exercise a few days per week with little activity in between, you probably don’t need that many calories, as exercise burns far fewer calories than most people assume (5, 6, 7)

summary

Factors like gender, age, height, and activity level influence whether you should follow a 3,000-calorie diet.

While many people are aiming to lose weight, others are looking to gain it.

Weight gain occurs when you consistently consume more calories than you burn each day. Depending on your activity level and body size, 3,000 calories may be greater than your current calorie needs, causing you to gain weight (8).

Why you may want to gain weight

There are several reasons for wanting to gain weight.

If you’re classified as underweight according to your body mass index (BMI), your healthcare provider or registered dietitian may recommend that you gain weight.

Alternatively, if you’re an athlete, you may want to gain weight — ideally in the form of muscle mass — to perform better at your sport.

Similarly, if you’re a bodybuilder or into powerlifting, you may desire to gain weight for increased muscle size and strength.

In other circumstances, you may have a health condition that increases your calorie needs, such as cancer or infection, or be recovering from major surgery (9, 10).

Safe rate of weight gain

While studies on the topic are scarce, an acceptable rate of weight gain is 0.5–2 pounds (0.2–0.9 kg) per week (11).

However, in people with severe undernutrition, weight gain of about 4.4 pounds (2 kg) per week has been accomplished safely (12).

Rapid weight gain may lead to uncomfortable side effects, such as bloating, stomach distress, and fluid retention. If you’re an athlete, these side effects can hinder your performance by negatively affecting your workouts or practices (13).

What’s more, rapid weight gain can increase your triglyceride levels, which may raise your risk of heart disease (14, 15).

How fast you gain weight depends on how many calories you need to maintain your weight.

If you maintain your weight on 2,000 calories per day, you will gain weight much quicker on a 3,000-calorie diet than someone who maintains their weight on 2,500 calories per day.

For example, one 8-week study showed that when 25 healthy people ate an additional 950 calories over their weight-maintenance calorie needs, they gained an average of 11.7 pounds (5.3 kg) — 7.7 pounds (3.5 kg) of which was fat (16).

If those same participants ate only 500 calories above their maintenance calorie needs for the same duration, they would likely gain much less weight.

summary

For some people, a 3,000-calorie may help you gain weight. An acceptable, safe rate of weight gain is 0.5–2 pounds (0.2–0.9 kg) per week.

The calories in your diet come from three macronutrients — carbs, fat, and protein.

Protein and carbs provide four calories per gram, compared with nine for fat.

The Acceptable Macronutrient Distribution Ranges (AMDRs) set forth by the Institute of Medicine of the National Academies recommend that people get (17):

  • 45–65% of their calories from carbs
  • 20–35% of their calories from fat
  • 10–35% of their calories from protein

The chart below applies these percentages to a 3,000-calorie diet:

When combined with resistance training, protein intakes on the higher end of the AMDR have been shown to reduce body fat gain due to excess calorie intake and increase muscle mass (18, 19, 20).

Resistance training can promote muscle gain instead of fat gain on a high-calorie diet (21).

Consume protein around your workouts, as well as equally spaced throughout your day to enhance muscle recovery and growth (22, 23).

summary

Higher protein intakes combined with resistance training can help optimize your body composition.

Consuming 3,000 calories per day from whole, unprocessed or minimally processed foods, such as fruits, vegetables, whole grains, healthy fats, and lean proteins, can be challenging.

That’s because these foods contain many nutrients but relatively few calories, requiring you to eat a much larger volume of food.

Conversely, it would be relatively easy to consume 3,000 calories from highly processed refined foods, such as bacon, potato chips, candies, cookies, sweetened cereals, and sugary drinks, as they’re highly palatable and packed with calories.

Yet, because these junk foods lack important nutrients for health, it’s vital to get most of your calories from nutritious whole foods, including:

  • Animal-based proteins: salmon, chicken, turkey, bison, whole eggs, and lean cuts of beef, such as flank or sirloin steak
  • Plant-based proteins: tofu, edamame, tempeh, peas, and chickpeas
  • Grains: oats, rice, breads, pastas, and quinoa
  • Dairy: milk, cottage cheese, kefir, and Greek yogurt.
  • Fats and oils: almonds, walnuts, flax seeds, olive oil, and nut butters like natural peanut or almond butter
  • Fruits: avocados, berries, apples, bananas, pears, oranges, grapes, etc.
  • Vegetables: squash, sweet potatoes, peas, kale, peppers, zucchini, broccoli, tomatoes, cauliflower, etc.

Plus, protein powders, including whey, casein, and plant-based powders like rice, soy, or pea, can be added to smoothies for a nutrient- and calorie-packed snack.

Lastly, mass gainer supplements, which often provide 1,000 calories per serving, are a convenient option, but it’s best to meet your calorie and nutrient needs through diet first.

Highly-processed, nutrient-poor foods to avoid or limit on a 3,000-calorie diet include:

  • Fried foods: French fries, onion rings, doughnuts, chicken strips, cheese sticks, etc.
  • Fast food: tacos, burgers, pizza, hot dogs, etc.
  • Sugary foods and drinks: soda, candy, sports drinks, sugary baked goods, sweetened tea, ice cream, sweet coffee drinks, etc.
  • Refined carbs: cookies, chips, sugary cereals, pastries, etc.

If most of your diet consists of whole, nutrient-dense foods, you can enjoy your favorite treats in moderation.

summary

Make sure most of your calories come from minimally-processed, nutrient-dense foods and reserve sweets and junk foods for the occasional treat.
