Exercisers who want to work on bodybuilding, put on weight, and become stronger typically make up a sizable population, even though weight loss is more often the motivation for people who are working out.

This can be made achievable by means of appropriate instruction, rest, and an accurate diet plan – the bulking diet in this situation.

The title of this diet gives us an indication of what it entails; a bulking diet is one in which the person exercising consumes enough food for their body to expand rapidly.

This is generally divided into two types of dieting; unclean and clean – and each is distinguished by the number of extra calories consumed throughout the diet. One point to remember is that the kind of food has no bearing on how tidy a bulk is.

What is Bulking?

In technical language, “bulking” is a dietary practice employed by those working out in which they create an energy surplus by consuming additional sustenance, thus ensuring the necessary elements and power for growing their muscle mass in a consistent fashion.

In order to maximize muscular growth, it is necessary to consume more calories than are being expended during higher levels of physical activity; otherwise, it would be impossible to achieve muscle growth.

It is important to understand that bulking usually causes an increase in both fat and muscle, which is an unavoidable aspect of human biology. Whether the bulking process is clean or messy, this outcome is inevitable.

Why Do Gym-goers Bulk?

Individuals who go to the gym, as well as those who are doing physical exercise, adhere to a bulking diet to promote and maintain the growth of their muscles.

The body needs more nourishment and energy to create new muscle fibers, and this is particularly essential as someone increases their training and consequently needs more energy.

Basic Principles of Bulking

Eating an excess of calories is not sufficient to have an effective bulking diet, thus it is important to abide by certain rules when deciding to follow this specific kind of dieting strategy, regardless of if it is a clean or dirty bulking diet.

The exerciser must make sure that their eating habits and the extra calories they are consuming can be kept up for a significant period of time. Eating a lot of food which is lacking specific vitamins or minerals can quickly result in malnourishment.

In addition, the individual doing exercise should also make sure to get an adequate amount of protein to support their muscle building. This is of extreme significance, and we will go into more detail about it.

Lastly, one must make sure the intensity of their exercise and the extra calories they are consuming are proportional.

Not working out enough or exercising the wrong way can lead to weight gain and lagging muscle growth. On the other hand, doing too much can use up the extra calories that you gain instead of having them become stored fat.

What is Dirty Bulking?

Dirty bulking is a rapid bulking diet plan in which people eat as much as they can while keeping an eye on the amount of protein they are consuming, in effort to build up as much muscle as they can with their exercise regimen.

It is regrettable that the abundance of food ingested will likely lead to the exercise enthusiast acquiring more fat than desired.

Once the dirty bulk is through, this may lead to an extended dieting phase, or potentially lead to medical complications in certain cases.

Dirty bulking usually occurs in the cases of elite athletes who are monitored by specialized coaches, people who are just starting their workout routines and experiencing the advantages of “newbie gains”, and individuals who need to put on weight in a quick amount of time.

Advantages of Dirty Bulking

The primary benefit of doing a dirty bulk is that it can help the exerciser quickly develop their muscles and maximize their muscle growth. It does this by boosting the rate of muscle protein synthesis and generating an optimal environment for gaining as much muscle fiber as possible.

In addition to this, there is the issue of convenience.

No need for calorie counting when practicing “dirty bulking”, making it simpler to consume foods that are high in calories, which can help make adding calories for the desired surplus easier.

In addition, eating too much and not being careful about nutrition is a definite way to add bulk, no matter if it is fat or muscle mass. There is no question that when a clean bulk diet is followed correctly, a healthy individual’s weight will increase.

The small number of calories contained in diets like clean bulking or weight gain diets might not be enough to cause any changes in body composition, as a variety of external factors could end up decreasing the likelihood of these calorie surpluses having a positive impact.

What is Clean Bulking?

Clean bulking is an alternate, more controlled, and more beneficial form of bulking in comparison to what is known as ‘dirty bulking’. It emphasizes the regulation of one’s macro and caloric intake, as well as making sure to keep a limited caloric surplus so as to not cause the formation of considerable fat deposits.

Many serious exercisers favor a diet for “clean bulking” because it enables them to keep their body fat and health levels the same while supplying the body with the necessary nutrients to build muscle.

Certain forms of a tidy weight gain diet plan go one more action, eliminating processed foods or other types of dishes considered to be not healthy – where the individual just consumes organic or locally-sourced meals.

Whilst this form of clean bulking is much more beneficial for health, it is also more tricky and usually has little effect on muscle growth.

Advantages of Clean Bulking

The primary benefit of a clean bulk is its productivity, as there are no additional fat deposits that must be burned off down the line.

A clean bulk’s purpose is to give the body enough nutrition to build muscle, thus making it cost and time effective.

When performing a clean bulk, it should be easy to maintain the same amount and type of meals as normal – this saves both time and money that would be used if focusing on a dirty bulk approach.

Dirty Bulk vs. Clean Bulk

Rate of Muscle Growth

If you want to put on weight quickly, you must eat a lot of calories – leading to the dirty bulk lifestyle. Let’s look at how quickly muscle growth can happen with either diet. What is the maximum rate of muscle growth you are able to sustain?

In one investigation assessing the rate at which trained sportspersons build muscle, a group subject to nutritional control and another allowed to eat at will were both observed. The nutrition-controlled group observed a dietary plan regulated by macros, aiming to grow total bodyweight by 0.7% weekly, or about an additional 500 calories daily. This diet prescribed that people get 1.4 to 2 grams of protein for every kg of body weight, and no more than 30% of their caloric intake to come from fat sources. Additionally, individuals were instructed to eat 5 to 7 nutritionally-dense meals in the course of a day. Post-workout nutrition was also included.

The ad libitum group had no nutritional mentoring and were asked to voluntarily increase their eating with a weight gain target of 0.7% body weight per week.

The protein intake between the two groups had no significant differences, yet the group that was under nutritional control consumed more calories, leading to a 0.4 percent body weight gain in a week whereas the other group had a 0.2 percent gain. Approximately 72% of the weight gained in the group that was carefully monitored nutritionally was muscle mass.

The results of this study demonstrate that consuming more calories helps to increase mass, but it is also essential to look at the amount of protein being taken in. Proteins are essential for attaining lean muscle mass, as they contain amino acids which form the foundation of every muscle.Without enough protein, it is hard to make any significant muscle growth.

It has been shown in another research that took a small collection of participants and gave each of them 1,000 extra calories per day to increase their weight. The participants were being fed different amounts of protein, ranging from 5%, 15%, or 25%, in relationship to their calories. All of the protein categories increased in weight, but the lower protein group had a much smaller increase.

The Winner

The conclusion of the scientific study is that a greater calorie intake will lead to weight gain at a quicker rate – to put on one pound of muscle demands an extra intake of 2,800 calories. A bulk diet with higher calorie intake, combined with the adequate amount of protein, can possibly result in enhanced muscle growth in a shorter amount of time.

Potential Fat Gain

The body composition should be taken into consideration when formulating a meal plan for bulking, as gaining weight will include both fat and muscle. Though you might be able to promote fast muscle growth, if you accumulate considerable fat along with it, you might have to consume a calorie restricted diet right after to reach your intended result.

In the aforementioned research, consuming more calories resulted in an expansion of lean body mass, yet it also provoked a noteworthy gain in weight due to body fat.

The second investigation mentioned above that focused on different levels of protein suggests that protein consumption is also essential in avoiding fat accumulation. If not enough protein is consumed, there won’t be enough amino acids to create muscle tissue, causing excess calories to result in extra fat. Some research indicates that if too many calories are consumed, proteins may be better at creating lean mass than fat accumulation. After someone has consumed enough protein, about 25 percent of their total calories, the effects of it stop increasing.

The amount of fat you gain could depend on your level of physical fitness, with beginners more likely to gain lean mass than individuals who have been lifting weights for a while and have built up their muscle mass already. This provides the explanation for why in one study, 2,000 additional calories in untrained people could bring about almost all of the weight increase to be muscle.

The Winner

Given the limited research on the comparison between bulk diets, it appears that taking a gradual and more nutrient oriented approach to weight gain, like lean bulking, will provide more muscle mass and keep off fatty deposits more than a fast method. No matter what physical shape you are in when you begin, as well as your body composition, it can heavily impact the kind of weight that can be put on and the pace at which it can be gained.


We are aware that developing muscle requires a boost in both protein intake and caloric consumption. While we can still debate whether a “clean bulk” or a “dirty bulk” diet offers the most nutritional benefit, it’s important to also consider the entire dietary aspect.

It is essential to have certain vitamins and minerals to help build muscle. Eating right plays an essential role in the healing process, lessening the chances of catching an illness, greater vigor, attitude, and all-around health. You could get further benefits by having more nutrient-rich food options in your bulking diet.

Lean bulking involves a diet that emphasizes whole, nutrient-rich foods, which has the potential to give you more nutrients than a bulk that consists mostly of processed foods full of calories but low in nutrition. Research suggests that vitamins A, C, and E may be instrumental in the development of muscle mass, and that these vitamins are predominantly found in plant-based, fruits and vegetables. Furthermore, it is believed that a good amount of B vitamins, zinc, vitamin D, and calcium is imperative, with dairy products and meat as the best sources.

It is not the quantity of food you intake that is important, but rather the kinds of food you consume. Even at higher calorie levels, nutrition deficiencies occur – a large number of people in this country are overfed and undernourished. If your diet consists mostly of foods that are high in fat, sugar, or are heavily processed, you may not be getting the essential nourishment you need to increase your muscle mass.

Eating a lot of ingredients that are not good for you such as added sugar, trans fats, saturated fat, cholesterol and sodium has been linked to various health risks and greater inflammation. Although these worries may not have an immediate impact on your capability to gain muscle, badly chosen food can gradually become a problem and have an adverse effect on your life. Eating healthy while in a bulk will set you up for more success when you attempt to maintain your weight afterwards, since you will already have a foundation of good nutritional habits.

The Winner

Getting the right amounts of nutrients in your diet, not just macronutrients and protein, could be beneficial for your overall health and ability to build muscle. A lean bulk is probably the preferable option when it comes to bulking, but it is essential to have an understanding of good nutrition with a focus on nutrient-rich foods.

The Verdict

Both bulking approaches have distinct advantages, and more often than not, the right diet for one person might not be worthwhile for another. Nevertheless, due to the existing studies, slim bulks are likely the ideal choice for getting more lean muscle and positioning yourself for more achievements and improved outcomes in the long term.
