4 Keys to an Anabolic Diet for Ectomorphs

A commonly held opinion is that people would rather be skinny than fat, but people who have this opinion have never tried to build muscle!

While an overweight person just has to cut calories and exercise more, a skinny person has to drastically change their calorie intake while tailoring their exercise to suit bulking. We’ve covered this before in our “How to Build Muscle with a Fast Metabolism” guide.ectomomorphneck

In this article we are going to look at the four pillars of dietary success, follow them religiously and you will soon be huge!

Pillar #1. Track Everything

Calorie counting, getting on the scales, and working out your macros sound like something that only people who want to lose weight would need to bother with. But actually, all of the above are just as important (if not more) for skinny people who want to gain weight.

The first thing that you need to ascertain is how many calories you are burning each day. You can use a website calculator to give you a decent estimate.

Once you have found out your average calories burned per day, you can work out how many calories you need to create a surplus. How aggressive you go with this can depend on your personal circumstances and your goals.

track macros
You also need to start taking measurements of everything. Your weight, body fat estimations, tape measurements of your arms, legs, chest, waist, and anywhere else which you want to improve.

Throughout your bulk you should continue to take measurements, ideally doing so at the same time each week (Monday at 7am for example). This way you will know if you are gaining size, and by how much.

Next it’s calorie counting, there will be a temptation to throw caution to the wind and just eat everything in sight. This approach can fail you for two reasons:

  1. It may lead to overeating which can lead to increased body fat (more so than is necessary), and
  2. You might still be under eating, people find it very difficult to estimate the amount of calories in their food.

Pillar #2. Hit Your Protein Target

While creating a calorie surplus is incredibly important, you must ensure that those calories contain the right amount of protein.

While fat and carbohydrate numbers should also be followed, there are many different ratios (ketogenic or high carb for example). But protein should always be very high.

A 2012 study states that your protein intake should be around 2.3-3.1g per kg of lean body mass (in other words your body weight minus body fat).

If you currently weigh 60kg and have a body fat percentage of 10% then you have a lean body mass of 54kg (60kg minus 10%). You can then pick an amount of protein that suits you (between 2.3 and 3.1 x 54). If you picked the higher number (3.1) that would equal 167.4g of protein per day.


The added protein is necessary for repairing and rebuilding damaged muscle fiber. When you exercise, you are basically breaking down these muscle fiber. Then through a process called Muscle Protein Synthesis (MPS) the damaged fiber are repaired and rebuilt into stronger and larger muscle fiber.

You need to be consuming a large amount of protein for this to occur. If you don’t then your muscle fibers will not be maximally repaired/rebuilt which will prevent growth.

You can increase protein by purchasing a whey protein supplement, eating more lean meats and fish, heck you could also eat less lean meat (pork, steak, etc) as you’re trying to bulk!

Additionally, there are protein (whey/casein/blends) powders with extra added calories for adding mass as fast as humanly possible. These types of powders are most commonly known as “mass gainers” or just “gainers”. We reviewed the top performers in our Top 7 Mass Gainers guide.

Vegetarians and vegans can look at lentils, nuts, and higher protein vegetables to provide adequate protein, but it is obviously more difficult to achieve without meat and dairy.

Pillar #3. Become a Meal Prep Expert

Now, if you are incredibly rich or have a very understanding and helpful partner you do not need to worry about this step. Just decide what your calories are, find some meals that match it and pass it to someone else to sort out for you (personal chef, family member, partner).

For those of you who aren’t insanely lucky you’ll have to learn how to meal prep.

You’re going to be eating a lot of foods to hit your calorie target, and if you’re doing it right your macro targets are going to be mighty close. This means that you’ll need to eat a lot of high protein meals.

This cannot be easily achieved if you are eating in restaurants or fast food outlets. So you are going to have to cook a lot of meals. This can be difficult, particularly if your work takes up a lot of your time.

Because of this, you will have to learn how to meal prep like a pro. This involves finding meals that you can make in large batches. Curries, stews, chillis, bolognaise, or basic chicken and broccoli.

Cook lots of the same meal at the same time, place them in Tupperware, and freeze them. Then each day you’ll have all your meals ready for you.

Learning how to cook well is probably one of the most underrated aspects of bulking, so follow recipes and get creative.

There’s nothing worse on earth than unseasoned chicken, broccoli, and rice with no sauce, particularly if you’ve had it in the freezer for 6 months.

While making this write down the macros and calories (many recipes now contain them, alternatively you can use myfitnesspal to estimate them).

Write them on a sticky label and place it on the Tupperware. It will really help you in 4 weeks when you grab a meal and want to track its calories.

Pillar #4. Be Consistent

The reason why most skinny guys never gain any muscle? A lack of consistency.

Sure they may say that they can eat what they want and never gain weight, but when it comes down to tracking calories, many go for hours and hours without eating anything.

Don’t follow this advice if you’re only going to do so for 3 weeks before ditching it. You need to set aside 6-8 weeks of following this diet advice (and combine it with being a beast in the gym) before you will start to see good results. But after that you’ll never look back.

There are no lifehacks that can immediately change your physique, no shortcuts to success. It’s all about following the right advice and being consistent.

Turning up day in, day out, and doing the work required. Follow everything on this list, lift heavy weights, and don’t give up. If you could use a little motivation we have identified the single most motivating bodybuilding video in existence. Give it a shot before your next workout to get into the mentality of a warrior..

12 weeks from now you’ll have some serious results coming your way!
