Weight loss is a common goal for people looking to optimize their nutritional status and help to prevent or treat chronic disease, however it is also a goal that is not in alignment with everyone. In fact, certain population groups may be looking for the exact opposite of this and are seeking to gain weight in an effective way.

What is a Good Meal Plan to Gain Weight?

Prepared meals high in protein

Thankfully, there are nutrition-driven approaches to help with weight gain, whether that is to help with malnutrition or an occurrence of unintentional weight loss, or to help build muscle mass, shifting of body composition, or a sport performance focus.

These evidence-based approaches to weight gain may include the addition of plant-based or lean protein food sources, healthy snacks throughout the day, and the addition of heart healthy fats as a source of additional calories to an already well-balanced diet. Just like any other dietary pattern, a focus on weight gain meal planning should incorporate balance and variety.

How to Gain Weight in a Healthy Way

Calculating Your Caloric Surplus

In order to understand the number of calories one’s body will require to achieve the weight gain desired, it is ultimately recommended to begin the process by first speaking with a professional. A Registered Dietitian Nutritionist (RDN) can help to calculate more precise measurements of an individual’s resting metabolic rate (RMR), utilizing evidence-based calculations and approaches. This typically takes into consideration height, weight, age, and activity levels.

Understand Your Resting Metabolic Rate

To help achieve weight gain, a caloric surplus would be necessary on top of the estimated RMR. Usually, individuals who are more active will require more calories to support weight gain as compared to sedentary individuals. Once your RMR is estimated with the help of an RDN and with consideration of activity levels, it may then be decided to increase calories by an additional 5-10% above the RMR. One other approach that is commonly utilized is to add an additional 500 calories per day to one’s RMR.

Balance Macronutrients

As with any other balanced dietary approach, for weight gain it is important to incorporate all of the macronutrients (carbohydrates, proteins, fats) without exclusion or severe restriction of one or the other. An RDN can help with determining specific percentages of each as based on an individual’s requirements since weight gain for sport performance is different from weight gain that is needed due to previous unintentional weight loss. There is not a one size fits all approach for macronutrient distribution. What can, however, be generalized is that carbohydrates should mostly be sourced from complex sources such as whole grains, fruits, vegetables, and nuts. Proteins sourced from mostly lean meats and poultry, fish, and other plant-based protein sources. And fats sourced from plant-based food sources such as olive oil, avocados, and nuts and seeds. 

Why Am I Not Gaining Weight?

Metabolism:

Your metabolism plays a crucial role in your ability to gain weight. A fast metabolism means your body burns calories quickly, making it harder to gain weight, while a slow metabolism burns calories at a slower rate, potentially leading to weight gain if calorie intake exceeds expenditure.

The Correct Caloric Intake:

One of the biggest factors influencing successful weight gain is the consistency of a caloric surplus. This surplus can be estimated in percentages (10-15% above RMR) or the addition of 500 calories above RMR.

Medical Conditions:

Another factor which can influence the pace of weight gain could be the presence of certain medical conditions. An example here would be individuals living with cancer who have unintentionally lost weight and are seeking a return to their usual body weight. Sometimes the disease process of cancer (and dependent on tumor type) produces what is called cancer cachexia, whereby the metabolic rate of an individual drastically increases, requiring more and more calories to sustain weight and prevent further loss. Sometimes, with disease states such as this, the initial focus may be weight maintenance or stabilization and then eventually weight gain.

How Do I Gain Weight If I Am Skinny?

Adding High Protein Foods to Your Meal Plan

In addition to creating a caloric surplus above the estimated RMR, the addition of foods high in protein may be required to achieve weight gain. This should be individualized based on the discussion with an RDN. Examples of calorically-dense and high protein foods include the below:

  • Fish rich in healthy fats (omega-3 fatty acids)- tuna or salmon are great choices here!
  • Plant based protein sources such as beans and legumes, chickpeas, black beans, lentils, and hummus
  • Meats and poultry like turkey, chicken, lean beef, pork and lamb
  • Eggs
  • Tofu
  • Any type of nut butter sourced from nuts such as peanuts, almonds, or cashews as examples
  • Whole grains like whole-wheat bread, whole-wheat pasta, brown rice, and quinoa
  • Higher-calorie fruits and vegetables like avocados, coconuts, bananas, apples,  mangoes, and any kind of dried fruits
  • Full-fat dairy products which may include cheese, yogurt, and whole milk

Adding Healthy Fats to Your Meals

From a macronutrient standpoint, fat is the most calorically dense macronutrient per gram therefore including higher fat food items may help you to gain weight sooner. It is important to source fats from mostly plant-based sources like olive oil and avocados because these sources will not contain saturated fats- which we know are correlated with increased risk of heart disease and inflammation.

Sometimes despite the increase in calories and protein from food sources, it can be challenging to meet the nutritional requirements needed for weight gain. Oral nutrition supplements are an additional option, ideally used between meals, to help increase calorie intake. These are usually pre-mixed shakes in bottles or they can be made at home using protein powders- there are many different ways to make different varieties of homemade protein shakes!
