To bulk up and build muscle, you need to be in a caloric surplus. The recommended daily allowance (RDA) is 2500 kcal for men and 2000 kcal for women, but to bulk, you need to eat more than this. The exact number of calories you need to add depends on your goals and current weight. For example, to build lean muscle mass, you need to eat 2000 to 2500 additional calories per pound gained. However, it's important to focus on healthy sources of fat, like extra-virgin olive oil, canola oil, nuts, avocados and fatty fish.

Caloric surplus: You need to be in a caloric surplus to build muscle
To build muscle, you need to be in a caloric surplus. This means eating more calories than you burn. For men, the recommended daily allowance (RDA) is 2500 calories, and for women, it's 2000 calories. However, if you're looking to bulk up, you'll need to consume more than this.
The number of extra calories you need to eat will depend on your goals and current maintenance calories. For example, if your maintenance calories are 3000, you should eat between 3150 and 3300 calories per day to lean bulk. Eating more than this, say 4000 calories, won't provide any additional muscle-building benefits and will simply result in more fat gain.
To build lean muscle mass, it's recommended to eat 2000 to 2500 additional calories per pound gained. However, it's important to focus on healthy sources of fat, such as unsaturated fats like extra-virgin olive oil, canola oil, nuts, avocados, and fatty fish. On the other hand, saturated fat should make up less than 10% of your daily calories, according to the Academy of Nutrition and Dietetics.

Macros: Macros are important when bulking, not just calories
To bulk up, you need to be in a caloric surplus. For example, if your maintenance calories are 3,000, to lean bulk, you should eat between 3,150 and 3,300 calories per day. Eating more than this will not help you gain more muscle, but will simply result in you putting on more fat.
To build lean muscle mass instead of fat, you need to eat 2,000 to 2,500 additional calories per pound gained. However, it's not just about calories. Macros are important, too. For example, you should focus on healthy sources of fat, like extra-virgin olive oil, canola oil, nuts, avocados and fatty fish. These are known as unsaturated fats. On the other end of the spectrum, saturated fat should make up less than 10% of your daily calories.
You also need to calculate your carb intake. For example, if you're eating 640 calories of protein and 990 of fat, you'll have 1,630 calories left to fill with carbs. Carbs are 4 calories per gram, so this equals 417.5 grams.

Healthy fats are an important part of a bulking diet. Focus on healthy sources of fat, like extra-virgin olive oil, avocados, canola oil, nuts and fatty fish. These are known as unsaturated fats. According to the Academy of Nutrition and Dietetics, saturated fat should make up less than 10% of your daily calories — that is, less than between 237 and 244 calories, or between 26 and 27 grams of saturated fat.
Avocados are a great source of healthy fats, as well as vitamins and minerals. They are high in monounsaturated fatty acids, which can help to reduce cholesterol and improve heart health. Avocados are also a good source of fibre, which can aid digestion and help you feel full for longer.
Extra-virgin olive oil is another excellent source of healthy fats. It is rich in antioxidants, which can help to protect your body from disease and improve overall health. Olive oil is also a good source of vitamin E, which is important for healthy skin and hair.
