Bulking is a term typically used in the context of bodybuilding and refers to a phase of training where the goal is to build muscle mass. It involves eating a high-calorie, protein-rich diet to support muscle development and intense weight training. The duration of the bulking phase can vary from a minimum of 4-6 weeks to several months or even years. The key to effective bulking is to eat a calculated calorie surplus, focusing on nutrient-dense, whole foods while limiting processed foods, added sugars, and deep-fried options. It is also important to ensure adequate hydration and consider taking supplements to support muscle growth. While there are different approaches to bulking, such as clean bulks and dirty bulks, the traditional method has been proven effective over time and is a good starting point for those looking to increase muscle mass.
Characteristics of a Bulking Diet
| Characteristics | Values |
|---|---|
| Calorie Intake | A bulking diet involves a sustained calorie surplus, with an increase of about 15% in daily calorie intake. This can be achieved by adding 250-500 calories to your current intake or using a bulking calorie calculator. |
| Protein | Protein is essential for muscle growth and should be included in every meal. Aim for 2g of protein per kg of body weight per day or at least 20% of your daily food intake. |
| Carbohydrates | Carbohydrates are an important source of energy and should be included in your diet. Oats are a good source of carbohydrates and can be added to meals or post-workout shakes. |
| Fats | Include healthy fats such as nuts, peanut butter, avocado, coconut oil, and oily fish. Avoid saturated and trans fat. |
| Meal Frequency | Consume 6 meals a day to pack in plenty of calories. |
| Meal Examples | Breakfast: Granola with whole milk and banana, bagels with peanut butter, poached eggs with salmon and avocado. Lunch: Healthy omelette, boiled or scrambled eggs. |
| Supplements | Consider mass gainers like Progain or Progain Extreme, or creatine to support your diet. |
| Water Intake | Stay well-hydrated by drinking 1.5-2 litres of water per day. |
| Workout Routine | Combine your diet with high-intensity resistance training to promote muscle growth. |
| Duration | A minimum of 4-6 weeks is recommended for a bulking phase. Longer bulks of 3-6 months or even a year are also common, followed by a cutting phase. |
| Clean vs. Dirty Bulking | Clean bulking focuses on whole, unprocessed foods and tightly regulates calorie surplus to minimize fat gain. Dirty bulking involves eating whatever desired, often leading to excessive fat gain. |

Calorie surplus
Bulking is a term typically used in the context of bodybuilding and refers to a phase of training where the goal is to build muscle mass. A successful bulking transformation depends on two key factors: eating at a calculated calorie surplus and eating healthy food.
A calorie surplus means consuming more calories than you burn, which leads to weight gain in the form of muscle or fat. This strategy is combined with high-intensity resistance training to boost muscle and strength gains. It is important to note that the weight gain during the bulking phase should ideally be in the form of muscle mass rather than excessive fat gain. This can be achieved through a clean bulk, which prioritises healthy, whole foods and just enough of a calorie surplus to promote muscle growth while minimising fat gain.
There are several ways to achieve a calorie surplus:
- Add Calories to Your Diet: If you are already eating a healthy and balanced diet, a simple way to achieve a calorie surplus is by adding extra calories on top of your current intake. This could be in the form of a smoothie between meals or by including more calorie-dense foods such as nuts, oats, eggs, and fatty fish like salmon.
- Follow a Meal Plan: You can use a bulking calorie calculator to estimate your calorie needs and then follow a meal plan that includes classic bulking recipes. This approach gives you more control over your diet and ensures you are getting the right amount of calories and nutrients.
- Track Your Calories: Using a calorie-tracking app can help you monitor your calorie intake and ensure you are in a surplus. It is a good idea to weigh yourself regularly and adjust your calorie intake based on your weight gain progress.
It is important to remember that the specific calorie surplus will vary depending on individual factors such as activity level, body size, metabolism, and goals. Additionally, while increasing your calorie intake is crucial, it is equally important to ensure that your diet includes nutrient-dense and protein-rich foods to support muscle growth effectively.

Protein-rich foods
Bulking involves eating a high-calorie, protein-rich diet to build muscle mass. It is important to eat a variety of nutrient-rich foods across different food groups.
Protein is essential for muscle growth, with optimal protein intake being 1.6g/kg/d and 0.4g/kg per meal. Aim for protein intake to be between 20-25% of your total calories for the day.
Meat, Poultry, and Fish
- Sirloin steak
- Ground beef
- Pork tenderloin
- Venison
- Chicken breast
- Salmon
- Tilapia
- Cod
Dairy
- Yogurt
- Cottage cheese
- Milk
- Cheese
Plant-Based Sources
- Beans
- Legumes
- Tofu
- Tempeh
- Seitan
It is also important to note that while bulking, it is recommended to limit alcohol, added sugars, and deep-fried foods.

Whole foods
The bulk bins offer a wide range of options, including grains such as quinoa, brown rice, and forbidden black rice; legumes like beans and lentils; nuts and seeds, including pecans, golden flax seeds, and pine nuts; and other items such as unsweetened flaked coconut, nutritional yeast, and nut butters. You can also find healthy snack options in the bulk section, such as granola, popcorn trail mix, and oat date bars.
In addition to the bulk department, Whole Foods offers a salad bar where you can get plain grains and dress them up at home, as well as a variety of ready-to-eat meals and on-the-go options. The store also provides a 7-day keto-friendly meal plan with recipes for breakfast, lunch, and dinner, which can be scaled up or down depending on your needs. Some of the meals included in this plan are cauliflower sandwich thins with bacon, lettuce, and tomato; pizza with mushroom; rotisserie chicken with greens; and salmon with riced cauliflower and steamed broccoli.

Supplements
Protein Powder/Shakes
Protein is essential for muscle repair, maintenance, and growth. It is the key player in the process of muscle protein synthesis, where the body repairs and rebuilds muscle fibres damaged during intense workouts. While it is important to get protein from whole foods, it can be challenging to meet your heightened protein needs through diet alone when bulking. This is where protein supplements come in. Whey protein shakes, for example, offer a convenient and concentrated source of high-quality protein. They ensure your muscles are continually fed the building blocks they need to grow bigger and stronger.
Creatine
Creatine is a molecule that is naturally produced in the body and provides energy for your muscles and other tissues. Taking it as a supplement can increase muscle creatine content, improving anaerobic performance. This means you can train harder for longer and recover between sets more quickly. Creatine is often present in bulking supplements, but supplementing with pure micronized creatine monohydrate allows you to control your dosage.
Multivitamins
Even with a well-balanced diet, you may not be getting all the vitamins you need to support muscle growth. Multivitamin supplements can help bridge this gap and ensure you are getting all the necessary nutrients to make gains.
Glutamine
During intense training, the body's glutamine levels can be significantly depleted, impacting muscle recovery, immune function, and gut health. Glutamine supplementation can help replenish these levels, reduce muscle soreness, and improve nutrient absorption, which is crucial when trying to maximise muscle gains.
ZMA
If you feel your diet is lacking in zinc and magnesium, or you suffer from reduced testosterone levels, ZMA supplementation may help improve your muscle mass.
Remember, supplements should not replace a well-structured, nutrient-rich diet and proper training. They are meant to complement your diet and enhance your results. Always consult a healthcare professional before taking any supplements to get tailored recommendations and ensure your safety.

Workout routine
Bulking requires a well-planned workout program and diet to encourage muscle growth and healthy weight gain. It is a term from bodybuilding that refers to a phase of training intended to facilitate muscle growth.
- Train the major muscle groups (chest, back, legs, arms, shoulders, and core) at least three to four times per week. These can be done as full-body workouts or splits.
- It is recommended to do strength training and consume a protein-packed diet.
- It is important to eat a calorie surplus so that your body has the energy to grow.
- It is recommended to consume 25-40 grams of protein before bed to stimulate tissue repair and minimize tissue breakdown during sleep. Examples of high-protein snacks include hard-boiled eggs, cottage cheese, Greek yogurt, or a protein shake.
- It is beneficial to add some quad-specific exercises into your routine, such as hack squats, to target your quadriceps effectively.
- Consider incorporating weight training for your lower body and advanced bodyweight movements for your upper body. Starting your workouts with exercises such as squats, front squats, or deadlifts can be beneficial.
- It is important to progressively overload your muscles during your bulking phase to stimulate muscle growth. Additionally, incorporating HIIT training or specifically-fat-burning cardio can be beneficial.
- Remember to stay hydrated by drinking 1.5–2 litres of water per day or 6-8 glasses.
- Supplements like creatine and protein powder can aid in muscle growth and recovery.
- It is recommended to bulk for 3-6 months followed by a shorter cutting phase. A specific workout routine can last for 12 weeks, followed by a week of rest.
