Published on: 2026-07-27 | Written by: Dr. Marian Asaad, Clinical Nutrition Specialist


Healthy weight gain is an important goal for individuals who are underweight or have difficulty maintaining a healthy body weight. Being underweight can negatively affect the immune system, muscle mass, energy levels, and overall health. Therefore, achieving a healthy weight should be based on a balanced nutritional program and a personalized treatment plan rather than simply eating large amounts of food. The primary objective is to increase lean muscle mass and improve overall health instead of gaining excess body fat.


What Is Being Underweight and When Does It Require Treatment?

Dr. Marian Asaad explains that being underweight is defined as having a Body Mass Index (BMI) below the normal range. It may result from poor nutrition, a high metabolic rate, chronic illnesses, digestive disorders, genetic factors, or psychological stress. An accurate medical and nutritional evaluation helps identify the underlying cause and develop a safe and effective treatment plan tailored to each individual.


Why Is It Difficult for Some People to Gain Weight?

Dr. Marian Asaad emphasizes that difficulty with weight gain may be associated with several factors, including a fast metabolism, poor appetite, nutrient malabsorption, hyperthyroidism, certain chronic diseases, or deficiencies in essential vitamins and minerals. A comprehensive assessment is essential for determining the exact cause and selecting the most appropriate nutritional strategy.


The Best Healthy Ways to Gain Weight

Dr. Marian Asaad confirms that healthy weight gain depends on gradually increasing calorie intake through nutrient-dense foods, including high-quality proteins, complex carbohydrates, healthy fats, dairy products, nuts, legumes, and dried fruits. She also highlights the importance of resistance training, which promotes muscle growth and helps achieve balanced and sustainable weight gain.


A Nutritional Plan for Healthy Weight Gain

Dr. Marian Asaad points out that the success of a weight gain program relies on organizing daily meals, eating healthy snacks between meals, staying well hydrated, getting adequate sleep, and maintaining regular follow-up appointments with a clinical nutrition specialist. The dietary plan should be adjusted according to the body's response to ensure optimal and lasting results.


How to Maintain a Healthy Weight After Gaining It

Dr. Marian Asaad explains that maintaining a healthy body weight requires continuing a balanced diet, avoiding skipped meals, engaging in regular physical activity, and avoiding excessive dependence on fast food or foods high in unhealthy fats and refined sugars. The ultimate goal is to improve long-term health rather than simply increasing body weight.


The Importance of Follow-Up with a Clinical Nutrition Specialist

Regular follow-up with a clinical nutrition specialist helps monitor progress, evaluate changes in body weight and body composition, and adjust the nutritional program according to individual needs. This personalized approach supports achieving the target weight safely while preserving muscle mass and promoting overall health.


Tips for Healthy Weight Gain

To achieve healthy and sustainable weight gain, it is recommended to:

  • Eat balanced meals rich in healthy calories.

  • Include a high-quality source of protein in every meal to support muscle growth.

  • Perform resistance training on a regular basis.

  • Get enough sleep to promote muscle recovery and healthy metabolism.

  • Follow a personalized nutrition plan and attend regular consultations with a clinical nutrition specialist.


Healthy weight gain is a comprehensive process that depends on accurate diagnosis, identifying the underlying cause of being underweight, following a balanced nutritional plan, engaging in appropriate physical activity, and maintaining regular medical follow-up. These measures help individuals achieve an ideal body weight safely while improving overall health, energy levels, muscle mass, and quality of life.
