Should a Skinny Person Eat More Calories for Weight Gain?

6 min read

According to the World Health Organization, being underweight can lead to a weakened immune system, fragile bones, and fatigue. This is why addressing the question, "Should a skinny person eat more calories?" is so important for those looking to improve their health.

Quick Summary

This guide explains the caloric surplus principle for weight gain, explores why some people struggle to put on weight, and provides actionable strategies for increasing calorie intake safely and sustainably with nutrient-dense foods.

Key Points

  • Caloric Surplus is Key: For weight gain, a skinny person must consume more calories than they burn. This is the foundational principle for building mass.

  • Focus on Nutrient-Dense Foods: Instead of junk food, prioritize healthy, calorie-rich options like nuts, avocados, and whole grains to ensure healthy and sustainable weight gain.

  • Increase Eating Frequency: For those with small appetites, eating five to six smaller, more frequent meals is often easier than trying to consume three large ones.

  • Incorporate High-Calorie Liquids: Utilize smoothies and shakes with added protein powder, nut butter, and milk to boost calorie intake without feeling overly full.

  • Pair Diet with Resistance Training: To ensure weight gain is primarily muscle and not fat, combine a caloric surplus with a consistent weightlifting routine.

  • Monitor and Adjust: Pay close attention to weekly weight changes. If you are not gaining weight, increase your daily calorie target incrementally.

  • Overcome High Metabolism: A naturally high metabolism (common in 'hardgainers') requires a significantly higher caloric surplus, so consistency is paramount.

  • Understand Health Risks: Being underweight carries health risks, including a compromised immune system and fragile bones, making weight gain an important health goal.

Understanding the Caloric Surplus for Weight Gain

For a skinny person to gain weight, they must consume more calories than their body expends. This fundamental principle is known as a caloric surplus. When your body is consistently in a surplus, it has the excess energy it needs to build new tissue, primarily muscle and fat. The amount of extra calories required varies greatly based on individual factors like metabolism, activity level, and genetics. For a hardgainer, or someone with a naturally high metabolism, this surplus might need to be significantly higher than for an average person.

The Science Behind Calorie Needs

Your body uses calories for three main purposes: your basal metabolic rate (BMR), the thermic effect of food (TEF), and your activity level. Your BMR is the energy your body needs to function at rest. The TEF is the energy used to digest and process food, and your activity level accounts for the calories burned during exercise and daily movement. When you consistently eat more calories than this total daily energy expenditure (TDEE), your body will store the extra energy as weight.

Why Some People Struggle to Gain Weight

For many, simply eating more is easier said than done. Several factors contribute to the difficulty many skinny individuals face when trying to pack on pounds:

  • High Metabolism: Some people naturally have a higher metabolic rate, meaning their bodies burn calories at a faster pace. This requires a much larger caloric surplus to achieve weight gain.
  • Poor Appetite: A small appetite can make it difficult to consume the large volumes of food necessary for a caloric surplus. This is why focusing on calorie-dense foods is crucial.
  • Active Lifestyle: A highly active job or intense workout regimen increases calorie expenditure, making it harder to maintain a consistent surplus.
  • Forgetting Calories from Liquids: People often overlook the easy calories available in beverages like milkshakes, juices, and other high-calorie drinks, which can make a significant difference.
  • Lack of Consistency: Gaining weight requires dedication. Skipping meals or not hitting daily calorie targets consistently is a common pitfall that prevents progress.

Strategies for Healthy Weight Gain

Gaining weight doesn't mean eating junk food. Focusing on nutrient-dense, high-calorie options is the key to building healthy muscle and body mass.

Increase Meal Frequency and Size

Instead of three large meals, try eating five to six smaller, more frequent meals throughout the day. This can be less daunting for those with smaller appetites. Also, don't be afraid to increase your portion sizes slightly at each meal.

Incorporate Calorie-Dense Foods

  • Healthy Fats: Add nuts, seeds, nut butters, and avocados to your meals and snacks. These are incredibly calorie-dense and rich in healthy fats.
  • Complex Carbohydrates: Include grains like oats, brown rice, and quinoa. Potatoes and sweet potatoes are also excellent sources of energy.
  • Protein: Prioritize lean protein sources like chicken, fish, eggs, and legumes. Protein is essential for building muscle mass.
  • Dairy: Full-fat dairy products like milk, yogurt, and cheese can be added to increase calorie and protein intake.

Utilize High-Calorie Liquids

Adding smoothies and shakes to your diet is an easy way to consume extra calories without feeling overly full. Combine milk, protein powder, fruits, and nut butter for a powerful calorie boost.

Comparison Table: Calorie Sources

Source Pros Cons Best for Example Avg Calories (per 100g/ml)
Healthy Fats High calorie density, nutrient-rich Can be high in saturated fat if not chosen carefully Boosting overall calorie intake with minimal volume Almonds ~575-600 kcal
Complex Carbs Sustained energy release, rich in fiber Can be very filling, harder to consume large amounts Fueling workouts and sustained energy Oats ~370-390 kcal
Lean Protein Essential for muscle repair and growth Can feel very satiating, might suppress appetite Building muscle mass and recovery Chicken breast ~165 kcal
High-Calorie Shakes Easy to consume, convenient Can lead to over-reliance on liquids, potential for unhealthy sugars Quick, on-the-go calories Milkshake with protein ~300-600 kcal

The Role of Exercise in Healthy Weight Gain

When discussing whether a skinny person should eat more calories, it’s critical to mention the importance of exercise. Engaging in resistance training, such as weightlifting, helps direct the caloric surplus toward building muscle rather than simply accumulating body fat. A balanced routine will aid in building a lean, strong physique. Aim for consistency, just as you do with your diet.

Conclusion: Making the Right Choices

To conclude, a skinny person absolutely should eat more calories to gain weight, but it must be done strategically and healthily. Focusing on a consistent caloric surplus with nutrient-dense foods is the cornerstone of sustainable weight gain. Combining this dietary approach with a proper strength-training regimen ensures that the weight gained is muscle, not just fat. By understanding the underlying principles and making informed food choices, anyone can achieve their weight gain goals safely and effectively.
