While many focus on weight loss, a significant portion of gym-goers aim to gain weight, specifically to increase muscle size and strength. While various methods exist, some can lead to unwanted fat gain. Clean bulking offers a sustainable and healthy strategy to achieve this goal. This article provides a comprehensive guide on clean bulking, covering its effectiveness, potential drawbacks, and ideal foods to eat and avoid.
Understanding Bulking: The Basics
Bulking, in essence, is a sustained calorie surplus. This means consistently consuming more calories than your body burns, resulting in weight gain primarily in the form of muscle or fat. This dietary approach is typically combined with high-intensity resistance training to maximize muscle and strength development.
Clean Bulking: A Controlled Approach
Clean bulking, also known as lean bulking, involves carefully managing your calorie surplus to minimize excessive fat gain. This approach emphasizes minimally processed, whole foods, while limiting high-calorie junk foods to promote a leaner body composition.
Clean bulking is often favored by athletes who need to maintain a relatively lean physique during the off-season, such as mixed martial arts (MMA) fighters, boxers, gymnasts, strength athletes, and physique competitors. However, it's important to note that clean bulking may not be suitable for everyone, as the associated weight gain usually occurs at a slower pace compared to other bulking methods.
Clean vs. Dirty Bulking: A Comparison
In contrast to the measured and gradual approach of clean bulking, dirty bulking takes a more liberal stance. With dirty bulking, no foods are off-limits, and the goal is to gain as much weight as possible, regardless of any accompanying fat gain.

While dirty bulking can be highly effective for rapid muscle and strength gains, it often comes with side effects like excess fat accumulation, sluggishness, and elevated cholesterol and blood sugar levels.
How to Start a Clean Bulk
The first step in embarking on a clean bulk is determining your maintenance calories - the number of calories required to maintain your current weight. Numerous online calculators can help you estimate this value.
Once you've established your maintenance calories, add a 10-20% calorie surplus. For example, a 175-pound (79-kg) man might add approximately 250-500 calories, while a 135-pound (61-kg) woman would add about 200-400 calories.
To support muscle growth, ensure a daily protein intake of 0.7-1 gram per pound of body weight (1.6-2.2 grams per kg). The remaining calories should come from carbohydrates and fats, depending on your individual preferences.
Tracking your intake using a smartphone app can be beneficial.

Monitor your progress by weighing yourself regularly, aiming for a weight gain of 0.25-0.5% of your body weight per week. For the 175-pound (79-kg) man and 135-pound (61-kg) woman, this translates to 0.4-0.8 pounds (0.2-0.4 kg) and 0.3-0.6 pounds (0.14-0.28 kg) of weight gain per week, respectively. If you're not seeing movement on the scale, gradually increase your weekly calorie intake by 100-200 calories.
Foods to Eat and Avoid on a Clean Bulk
Unlike dirty bulking, clean bulking primarily revolves around whole, unprocessed foods, although it allows for small indulgences of high-calorie, processed items. While moderation is key, certain foods can make it challenging to maintain a controlled calorie surplus and should be limited or avoided.
Foods to Emphasize
- Lean proteins: chicken, fish, turkey, beef, pork, Greek yogurt, cottage cheese, reduced-fat cheese, protein powders, tofu and tempeh, eggs, and egg whites
- Healthy fats: olive oil, avocado, nuts, nut butters, fatty fish, and seeds like chia, hemp, and flax seeds
- Legumes: all beans, including chickpeas, kidney beans, navy beans, black beans, and great northern beans
- High-quality carbs: oats, quinoa, whole-grain pasta, white and sweet potatoes, white and brown rice
- Fruits: apples, oranges, bananas, pineapple, grapefruit, and all types of berries
- Non-starchy vegetables: peppers, asparagus, green beans, mushrooms, onions, tomatoes, zucchini, carrots, and celery
- Cruciferous veggies: broccoli, cauliflower, Brussels sprouts, and cabbage
- Dark leafy greens: spinach, Swiss chard, collard greens, and kale
- Beverages: water, seltzer, diet soda, tea, coffee, and kombucha
Foods to Limit or Avoid
- Highly processed foods: fried foods, canned soups and stews, sugary cereals, chips, fast food, full-fat ice cream, packaged pastries, cakes, cookies, and processed meats like bacon, sausage, ham, salami, and pâté
- Proteins: fatty cuts of beef or pork and processed pork or beef sausage
- Saturated fats: margarine, butter, and certain oils
- Beverages: soft drinks, sweetened coffee, sweet tea, lemonade, and other sugary drinks
Advantages of Clean Bulking
Clean bulking offers several advantages over dirty bulking:
- May limit excess fat gain: Clean bulking's calorie-controlled approach helps prevent excessive fat accumulation. A conservative surplus of 350-500 calories per day is generally effective for promoting muscle growth while minimizing fat storage.
- May prevent negative health effects: The careful and gradual nature of clean bulking may reduce the risk of negative health consequences associated with excessive calorie intake, such as elevated cholesterol and blood sugar levels.
- Excellent nutrition content: Clean bulking emphasizes whole foods, resulting in a higher intake of vitamins, minerals, phytonutrients, and fiber. Phytonutrients have anti-inflammatory properties, while high-fiber diets are linked to improved digestive health and a reduced risk of various ailments.
Potential Downsides of Clean Bulking
Despite its advantages, clean bulking also has some potential drawbacks:
- Your progress may stall: The tightly controlled calorie surplus in clean bulking can lead to slow or stagnant progress. Underestimating the calories needed for muscle growth can hinder gains.
- May lack flexibility: Clean bulking promotes a fairly rigid eating pattern, limiting food choices to prevent excess fat gain and maintain good health. This can be challenging to sustain long-term or during social events.
Striking a Balance: A More Flexible Approach
If the limitations of clean bulking are too restrictive, consider a more flexible approach. Aim to dedicate about 90% of your calorie intake to whole, unprocessed foods and the remaining 10% to discretionary calories from high-fat or high-sugar foods. This can provide a balance between lean muscle growth, limited fat gain, and greater dietary flexibility.

Bulking and Cutting: Potential Risks to Consider
Kyle T. Ganson, PhD, an assistant professor at the University of Toronto specializing in eating disorders and muscle-building behaviors, cautions that improper bulking can lead to excess fat gain and body dissatisfaction. Similarly, improper cutting can result in muscle loss, nutrient deficiencies, and increased preoccupation with food and body image.
Ganson notes that bulking and cutting can promote disordered eating patterns, obsessive body monitoring, and unhealthy weight cycling. Rapid shifts in caloric intake and weight can also negatively impact cardiovascular health, hormonal balance, and psychological well-being, especially among adolescents and young adults.
Key Risks Associated with Bulking and Cutting:
- Excess Fat Gain or Muscle Loss: Balancing weight gain during bulking and muscle retention during cutting requires careful management.
- Digestion Issues: High food intake during bulking can cause digestive discomfort, while cutting may disrupt the body's natural rhythms.
- Eating Disorders: Bulking and cutting can contribute to restrictive or compulsive eating patterns.
- Mental Health Problems: This fitness approach can lead to an excessive focus on exercise and diet, potentially leading to obsessive behavior or muscle dysmorphia.
- Poor Energy Levels: An imbalanced diet can affect daily performance and concentration.
- Negative Impact on Heart Health: Extra weight from bulking, poor food choices, and rapid weight loss can strain the heart.
- Hormonal Imbalance: Extreme calorie intake or weight loss can disrupt hormone levels.
Individuals with a history of disordered eating or those who are pregnant, underweight, or have certain medical conditions should avoid bulking and cutting without professional guidance.
Key Elements of a Muscle-Building Diet
To effectively fuel muscle growth, consider these key elements:
- Sufficient Protein Intake: Aim for 0.7-1 gram of protein per pound of body weight per day to support muscle repair and growth.
- Caloric Surplus: Consume more calories than you burn daily to provide the energy needed for muscle growth.
- Carbohydrates for Energy: Prioritize carbohydrates from sources like fruits, vegetables, and whole grains to fuel workouts and support recovery.
Macronutrient Ratios for Muscle Gain
A balanced macronutrient ratio can help optimize muscle growth. A general guideline is:
- 25% protein
- 50% carbohydrates
- 25% fat
Supplements to Support a Bulking Diet
While a well-planned diet should be the foundation of your bulking strategy, certain supplements can provide additional support:
- Protein powder: Helps ensure you meet your daily protein goals.
- Creatine monohydrate: Improves workout intensity, power, strength, and overall output.
The Importance of Meal Timing
In addition to food choices, meal timing plays a role in muscle growth:
- Meal frequency: Eating protein every two to four hours supports consistent muscle protein synthesis.
- Distribution: Aim to consume 25-40 grams of protein per meal, including post-workout.
- Carb timing: Prioritize carbs before and after workouts to support performance and recovery.
