How to Gain Weight on the Paleo Diet: A Comprehensive Guide

Introducing the Paleo diet: A throwback to the eating habits of our ancestors, promoting natural and unprocessed foods. Yet, it’s often linked with weight loss – which might make you wonder, “Can I use it to gain weight?”

Absolutely. You can still bulk up while keeping to the Paleo principles. But how? Let’s delve in.

Understanding the Paleo Diet

The Paleo diet takes us back to the Stone Age, focusing on what our forebears might have hunted or gathered. It’s a menu of lean meats, fish, fruits, vegetables, nuts, and seeds.

This dietary plan discards processed foods, sugar, dairy, and grains. While this often leads to weight loss, adjusting portions and macronutrient ratios can turn it into a weight-gain diet.

Increasing Calorie Intake

Gaining weight requires consuming more calories than your body burns. In the context of the Paleo diet, that means:

  • Eating larger portions: Gradually increase the size of your meals, ensuring that you get more calories from each serving.
  • Consuming more meals: Adding another meal or two in your daily routine could make a substantial difference. Think of a second lunch or an additional hefty snack.
  • Opting for calorie-dense foods: Not all Paleo foods are created equal. Choosing calorie-rich options will promote weight gain more effectively.

Choosing Calorie-Dense Paleo Foods

Not sure which foods pack the most calories? Here are some Paleo-friendly choices:

  • Avocados: Loaded with healthy fats and fiber, avocados are an excellent choice. A single avocado contains around 320 calories.
  • Nuts and seeds: They are not only nutrient-dense but also high in calories. Almonds, for instance, have about 160 calories per ounce.
  • Fatty meats: Select cuts of meat that are higher in fat. For instance, rib-eye steak is not only delicious but also calorie-rich.

Sample Paleo Meal Plan for Weight Gain

Creating a meal plan can make it easier to meet your calorie and nutrient goals. Here’s a sample 7-day meal plan that aligns with the Paleo diet and is designed to help you gain weight:

Remember to adjust portion sizes and the number of meals based on your individual calorie needs and hunger levels. This table should serve as a starting point for you to build a plan that best suits your preferences and goals.

Incorporating Regular Exercise

Exercise is not only about shedding pounds. When done right, it can aid in gaining weight too. Here’s how:

  • Strength training: By lifting weights and building muscle, you can gain weight in a healthy way. Stronger muscles require more calories for maintenance, boosting your overall calorie consumption.
  • Eating post-workout meals: Consuming protein and carbs after workouts can help replenish energy stores and repair muscle tissues, promoting weight gain.

Overcoming Common Challenges

Adapting to any new diet can come with its fair share of hurdles. Here are common challenges you may face when trying to gain weight on the Paleo diet, and how to overcome them:

  • Feeling full too quickly: Paleo foods, being rich in fiber and protein, can make you feel full quickly. Try consuming smaller, more frequent meals throughout the day instead of three large ones.
  • Lack of variety: Sticking to Paleo guidelines might feel restrictive. Experiment with different recipes and flavors to keep your meals exciting.
  • Digestive issues: A sudden shift to a high-fiber diet can cause digestive discomfort. Start slowly and give your body time to adjust.

Understanding the Difficulty of Gaining Weight on the Paleo Diet

The Paleo diet can make gaining weight challenging because it emphasizes whole, unprocessed foods that are naturally low in calories but high in nutrients. It’s also high in protein and fiber, both of which can suppress appetite, making it hard to consume enough calories to gain weight.

Think of it as trying to fill a gas tank with high-octane fuel. It burns cleaner and more efficiently, leaving you needing less to get more done. But if your goal is to add mass, you’ll need to find ways to get more of this “fuel” into your diet.

Supplements for Weight Gain on the Paleo Diet

If you find it difficult to meet your calorie requirements through food alone, supplements might help. Here are a few options:

  • Protein Powders: Opt for Paleo-friendly protein powders, such as egg protein or beef protein isolates. They can help increase your protein intake and support muscle growth.
  • Meal Replacement Shakes: These are high in calories and nutrients, making them a good option for adding extra meals to your day without feeling overly full.
  • Fish Oil: High in omega-3 fatty acids, fish oil supplements can provide healthy fats and extra calories.

Always remember to consult a healthcare provider before adding any supplements to your diet.

Tracking Your Progress

Without keeping tabs on your progress, you won’t know if your plan is working. Thus, track your weight and adjust your diet and exercise routine accordingly.

Remember, healthy weight gain is a gradual process. Patience and consistency are key.


Gaining weight on the Paleo diet is a walk in the park, once you understand how. Just as our ancestors adapted to their environment, you can adjust your Paleo diet to meet your weight goals. By increasing your calorie intake, choosing calorie-dense foods, exercising regularly, and tracking your progress, you’ll be well on your way to a healthier, stronger you.

Frequently Asked Questions

Q1: Can I eat grains if I’m trying to gain weight on the Paleo diet?

No, grains are typically avoided in a Paleo diet due to their high phytic acid content, which can interfere with mineral absorption in the body. Instead, try to consume more calorie-dense fruits, vegetables, nuts, seeds, and meats.

Q2: Is dairy allowed on the Paleo diet?

Most versions of the Paleo diet exclude dairy. However, some people choose to include full-fat, organic dairy products, particularly if their main goal is to gain weight. Always opt for dairy that’s free from additives and artificial sweeteners if you decide to include it in your diet.

Q3: Can I eat processed foods if they help me gain weight?

The Paleo diet primarily focuses on whole, unprocessed foods, so processed foods should ideally be avoided even if they help you gain weight. Remember, the goal is not just to gain weight but to do so in a healthy way.

Q4: What if I’m allergic to nuts?

If you’re allergic to nuts, focus on other calorie-dense foods like avocado, fatty meats, and seeds. Always consult with a healthcare provider or a dietitian for personalized advice based on your specific dietary needs.

Q5: How fast can I expect to gain weight on the Paleo diet?

Weight gain, like weight loss, is a gradual process. Healthy weight gain is typically around 0.5-1 pound per week. This rate might be faster in the initial weeks and then slow down.

Q6: Is it necessary to exercise while trying to gain weight on the Paleo diet?

Yes, exercising, especially strength training, is beneficial as it helps to ensure that the weight you gain is muscle and not fat.

Q7: Can I follow a vegetarian or vegan Paleo diet to gain weight?

While the traditional Paleo diet is heavy on animal products, it’s possible to follow a vegetarian or even vegan Paleo diet with some modifications. You’ll need to rely on plant sources of protein and fats, such as nuts, seeds, and avocados, to ensure you’re getting enough calories.

Q8: Can I drink alcohol on the Paleo diet?

Most alcoholic beverages are not considered Paleo-friendly due to their high sugar content and the processing they undergo. Opt for water, herbal tea, and fresh fruit juices instead.

Remember, individual results can vary. Always consult with a healthcare provider or a dietitian to understand what will work best for you.
