How large a calorie surplus do you need to build muscle?

A moderate surplus of around 300–500 calories above your daily needs gives the body what it needs to replenish energy stores, support protein synthesis and build muscle, while keeping body fat percentage stable.

How much protein should you eat during a clean bulk?

Around 1.8–2.2 grams of protein per kilogram of body weight per day, from sources such as chicken, turkey, beef, eggs, fish, low-fat dairy and plant sources like beans and lentils.

How do you calculate your daily calorie needs?

First calculate your basal metabolic rate (BMR) with Mifflin's formula: for women (10 x weight in kg) + (6.25 x height in cm) − (5 x age) − 161, and for men the same calculation + 5. Then multiply the BMR by the activity factor (PAL) that matches your daily activity level.

How many calories does each gram of protein, carbohydrate and fat contain?

Carbohydrates and proteins contain 4 calories per gram, while fat contains 9 calories per gram.

How much fish is recommended per week, and what if you eat little fish?

It is recommended to eat 300–450 g of lean fish per week, of which 200 g should be fatty fish. If you eat little fish, an omega-3 supplement is wise, with at least 250 mg EPA/DHA daily.

Build Muscle This Winter – Nutrition Plan for Clean Bulk | Hardworkout Magazine

Key takeaways

- A clean bulk means eating in a moderate surplus of 300–500 calories above daily needs, not eating as much as possible.

- Protein intake of 1.8–2.2 grams per kilogram of body weight per day supports muscle building during a bulk.

- Carbohydrates should make up 45–55 per cent of total calorie intake and fat 25–30 per cent.

- Daily calorie needs are found by calculating BMR with the Mifflin formula and multiplying it by an activity factor (PAL) of 1.2 to 2.4.

What is a clean bulk, and why does winter suit it?

Winter is the best time to build muscle and get stronger – a period where you can eat a bit more, train heavier, and focus on progress rather than form. This plan follows the principle of a clean bulk – a moderate calorie surplus with nutrient-rich food that provides steady and measurable progress over time.

When you eat enough and the right food, your body gets enough energy to recover, build, and perform better in training. The goal is to increase muscle mass without the body fat percentage rising more than necessary.

The Purpose of the Plan

The goal of this nutrition plan is to provide the body with enough and the right fuel to build muscle and increase strength in a controlled manner.

Many train hard and purposefully, but eat too little to make progress. When you are in a slight calorie surplus, the body gets the energy it needs to recover after training, replenish glycogen stores, and build more muscle over time.

The point is not to eat as much as possible, but to eat smart – enough to grow, without compromising your shape.

How many calories should you eat in a surplus?

When the goal is to build muscle or increase strength, the body requires more energy than normal.

Heavy strength training depletes glycogen stores and initiates an extensive recovery process that both costs energy and requires sufficient nutrition.

For the body to adapt to the training – that is, to build larger and stronger muscles – energy intake must exceed expenditure. Without a surplus, the body will primarily use food to meet basic needs, not to build new muscle mass.

A moderate caloric surplus of around 300–500 calories above your daily needs provides ideal conditions for progress.

It gives the body the surplus it needs to replenish energy stores, support protein synthesis, and build muscle effectively – while keeping body fat percentage stable.

It is this balance that distinguishes a targeted clean bulk from uncontrolled weight gain.

Choose foods with high protein quality for optimal muscle growth. Foods You Should Focus on to Build Muscle

How much protein, carbohydrate and fat do you need?

A caloric surplus is not just about eating more – it’s about eating right.

The goal is to provide the body with energy and high-quality building blocks so that the muscles get what they need to grow, while you maintain balance.

Choose foods that provide stable energy, good digestion, and nutritional value that you actually benefit from:

Protein: Chicken, turkey, beef, ground beef, eggs, fish, low-fat dairy products, and plant-based sources like beans and lentils.

Proteins are necessary for building and maintaining muscle mass and should make up around 1.8–2.2 grams per kilogram of body weight per day. Carbohydrates: Oats, potatoes, sweet potatoes, rice, whole grain pasta, quinoa, and whole grain bread.

Carbohydrates replenish glycogen stores, provide energy for heavy sessions, and support recovery. They should account for 45–55 % of total caloric intake. Fat: Avocado, nuts, seeds, olive oil, and fatty fish.

Healthy fats contribute to hormonal balance, energy, and the absorption of fat-soluble vitamins, and should be 25–30 % of total intake. - Vegetables and berries: Should be a natural part of all main meals to ensure enough micronutrients and antioxidants that support the immune system and recovery.

A balanced clean bulk is not about eating as much as possible, but about hitting the right amount and quality of food so that the body gets enough nutrition to build more muscle.

Combined with structured strength training and sufficient sleep, it creates optimal conditions for muscle growth and increased strength over time.

How many meals a day does the plan contain?

This meal plan consists of 5 meals and 2600-2700 calories per day. The menu can easily be adjusted to your needs as the nutritional content is provided for all recipes, as well as for each food item.

For simplicity, breakfast and lunch are the same from day to day, while dinner and snacks vary – to provide flexibility, different flavors, and the right macro distribution.

Lunch is designed to be split into two smaller meals, so that there are a total of 5 meals throughout the day. The snack is well-suited to be consumed right after training, for quick replenishment of energy and nutrients.

Monday

For breakfast, there will be a warm and filling porridge with oats, eggs, and raspberries – a perfect start to the day with a good balance of protein, carbohydrates, and healthy fats.

Lunch will be a fresh and filling barley salad with chicken, avocado, and vegetables – easy to make, but nutritious and full of flavor.

For dinner, there will be juicy salmon with sweet potato mash and crispy kale chips – a dish that combines protein, omega-3, and slow carbohydrates.

Snack will be an energy-rich shake that provides a quick replenishment of protein and carbohydrates after training.
