According to WikiPedia, amino acids are biological compounds that contains amine and carboxylic acid functional groups. The key elements of every amino acids are carbon, hydrogen, oxygen and nitrogen.

As of this writing, there are over 500 known amino acids that are classified in three classes – essential, non-essential and conditional amino acids.

In layman’s term, amino acids are organic compounds that combine to form proteins. Both amino acids and proteins are the building blocks of life.

When protein is digested, it is once again broken down into amino acids, that are selectively combined together to do various uses.

These new proteins formed in your body are what make up most of the solid matter in your body such skin, heart, intestines, bones, and of course muscles.

Aside from being an important compound in the body, amino acids are beneficial for your weight loss as it can help boost your metabolism, energy levels and some amino acids even help promote craving reduction. Aside from that, amino acids also promotes muscle growth.

8 Essential Amino Acids for Weight Loss

As mentioned above, there are hundreds of amino acids available in the body. But I will only discuss only just a few of the most important amino acids that are truly beneficial for your weight loss program.

Well, depending on who you talk, there are probably around 30 to 50 known and popular amino acids that you might already know by now. Most of these amino acids are classified as essential, which means that you can only acquire them from your diet.

So are some of the free form of amino acids that I am going to discuss later in this article are the main compounds that are often associated to either weight loss or muscle building.

  • Branched chain amino acids (BCAA)
  • Leucine
  • Lysine
  • Isoleucine
  • Histidine
  • Phenylalanine
  • Threonine
  • Glutamine
  • Valine
  • Arginine
  • HMB

So How does Amino Acids Work?

To learn how amino acids can help you lose weight, we have to dig deep into detail on how each of the aforementioned compounds above work inside your body. Only then we can get clear insight if amino acids are truly beneficial for your fitness program.

Branched Chain Amino Acids

BCAA’s are commonly used in most bodybuilding and weight loss supplements because of their ability to maintain and repair muscle tissues, while promote fat loss.

BCAA’s include valine, isoleucine, and leucine. All these compounds are used to help treat dizziness, headache, fatigue, depression, irritability and many others.

Valine helps maintain nitrogen balance and helps preserve glucose. Isoleucine on the other hand promotes muscle growth, recovery, regulates blood sugar levels and stimulates HGH release.

Lastly, leucine helps regulates blood sugar levels, growth and repair of tissues and skeletal muscles. Like isoleucine, leucine is a powerful potentiator of human growth hormone (HGH), which is the reason why many experts believe that leucine is the strongest amino acids in BCAAs.

One perfect supplement that can provide high amounts of BCAA’s is Amino Slim.


Sourced from animal meats and dairy products, threonine is commonly found in the heart, skeletal muscle and nerve tissue in the central nervous system.

This amino acid is essential in maintaining proper protein balance as it is used to form two important active substances – collagen and elastin. This means that threonine can help produce antibodies that will help strengthen your health.

Plus, threonine helps in the absorption of protein, muscle maintenance and is essential for brain health.


A non-essential amino acid, glutamine is present in the body in large amounts (about 60% of your body’s total amino acid).

Glutamine is known to help improve brain function, increases GABA, and is used for muscle tissue synthesis. This means that glutamine is one of the best supplements that you can get in the market for your weight loss program.

Dieters and bodybuilders use glutamine to help preserve muscle mass and boost energy levels and physical performance.


If you want an amino acid that can actually help you lose weight, then arginine is the right one for you.

This compound is known for its surprising nitrogen retention properties and is one of the key elements in muscle protein synthesis. Arginine helps strengthen your immune system, stimulate the size and function of the thymus gland, and is known as a sexual stimulant.

For weight loss, arginine works by regulating muscle mass gain while limiting fat storage and production. Arginine keeps your fat alive in the system and uses it for energy, this is the key in weight maintenance ability of arginine.


A popular amino acid due to its alleged fat burning properties, carnitine contains two components that are said to provide weight loss effects – L-Carnitine and Acetyl-L-Carnitine.

Experts suggest that carnitine’s main function is to transport long-chain fatty acids, which leads to significant reduction in body-fat percentage, while boosting energy.

Carnitine is also beneficial to your health as it helps increase the efficacy of vitamins C and E, both of which are known antioxidants. Carnitine is also used by athletes and bodybuilders.


HMB or Beta-Hydroxy Beta-Methyl Butyrate, is an amino acid that came from leucine. It triggers other functions of leucine and plays a great role in muscle synthesis by doubling the rate of protein being used by your body, which leads to more muscle mass but less fat storage.

Another worthy supplement, HMB helps improve the use of free amino acids and prevents them from minimizing protein breakdown. It also helps protect muscle protein, metabolizing fat and increasing the use of free amino acids as your body’s primary source of energy.



So can amino acids help you lose weight? Well, of course yes!

Amino acids are truly beneficial to your health as it can help improve your cardiovascular health, sexual health, mental health, elevates physical performance, boosts energy levels, supports fat loss and promotes anabolic effects.

You can get amino acids from your diet such as meat, dairy products and many others. But if you want to get a high dose of amino acids especially BCAA’s to propel your weight loss, then I suggest that you take a supplement is high on amino acids.
