Growth hormone, also known as GH or somatotropin, is a vital hormone produced by the pituitary gland located at the base of the brain. It plays a crucial role in various aspects of the body, including growth, body composition, cell repair, and metabolic processes.
Growth hormone also influences muscle growth, strength, exercise performance, and aids in recovery from injuries and illnesses. Having low levels of growth hormone can negatively impact the quality of life, increase the risk of illnesses, and contribute to fat accumulation. Maintaining appropriate levels of growth hormone is especially important during weight loss, recovery from injuries, and periods of intense physical training. Interestingly, our dietary choices and lifestyle patterns significantly affect growth hormone levels.
Here are 11 scientifically-backed ways to increase growth hormone levels:
(1) Reduce Body Fat:
The amount of body fat can influence the production of growth hormone. People with higher levels of body fat, particularly abdominal fat, tend to produce less growth hormone and may have an increased risk of illnesses. Research has shown that individuals with more significant amounts of body fat had significantly lower levels of growth hormone, up to 50% less, compared to those with lower body fat levels. In a study monitoring growth hormone secretion over 24 hours, it was observed that individuals with abdominal fat had a substantial reduction in growth hormone secretion.
It's important to note that while these factors can influence growth hormone levels, individual responses may vary, and other factors like genetics and overall health also play a role in hormone production. Consulting a healthcare professional for personalized advice on optimizing hormone levels is recommended
What's interesting is that research has found that fat can have a greater impact on the secretion of growth hormone (GH) in men compared to women. Nevertheless, reducing fat is a good solution for both men and women.
Research has uncovered that obese individuals tend to have lower levels of insulin-like growth factor-1 (IGF-1), which is a hormone associated with body growth, much like growth hormone. After volunteers managed to lose weight, their hormone levels returned to normal.
Belly fat is the most dangerous type of accumulated fat and is closely linked to various health risks. Reducing abdominal fat can help regulate growth hormone levels and other aspects related to our health
(2) Intermittent Fasting
Research has shown that intermittent fasting can significantly boost growth hormone (GH) levels. One study found that fasting for 3 days increased GH levels by 300%, and after a week of fasting, GH levels increased by up to 1,250%. Another study reported similar results, with GH levels increasing 2-3 times after just 2-3 days of fasting. However, it's important to note that continuous fasting may have unsustainable long-term effects.
Intermittent fasting is a popular eating pattern that involves stopping food consumption for short periods. There are various ways to practice intermittent fasting, but one of the most common methods is to have an 8-hour eating window and a 16-hour fasting period, during which no calories are consumed. Another approach is to have 2 days each week where you consume only 500-600 calories.
Fasting helps regulate GH levels for two main reasons:
1. It helps reduce body fat, which is directly related to GH levels.
2. It keeps insulin levels low for most of the day. Insulin is primarily released when we eat, and research has shown that high insulin levels can negatively impact GH production. The graph below illustrates a significant difference in GH levels on fasting days compared to regular eating days.
Indeed, fasting for shorter periods, such as 12-16 hours, can also yield beneficial results
(3) Arginine
Arginine may help increase growth hormone levels. While many individuals take arginine amino acid supplements to aid in exercise performance, research has shown mixed results regarding its impact on GH levels. Interestingly, for those who solely consume arginine supplements without engaging in exercise, there have been findings of significant increases in GH levels, supported by some studies.
There is also a study that examined the effects of receiving arginine in doses ranging from 45-114 milligrams per pound of body weight, equivalent to approximately 100-200 milligrams per kilogram (about 6-15 grams per day). This study found that individuals who received higher doses of arginine experienced an increase in GH levels of up to 60%.
(4) Reduce Sugar Intake
Increasing insulin levels can lead to a reduction in GH production. Refined carbohydrates and sugar are known to be the foods that most significantly elevate insulin levels. Therefore, reducing the consumption of these foods is essential for regulating GH hormone levels. One study conducted among healthy individuals found that those with high GH levels had 3-4 times the GH hormone levels compared to individuals with diabetes. It also indicated better tolerance to carbohydrate deprivation and improved insulin function.
In addition to impacting insulin levels, excessive sugar consumption can lead to obesity and weight gain, which in turn affects GH hormone levels. This means that occasional consumption of these foods may not have a long-term negative impact on GH hormone levels. It is crucial to have a balanced approach to food choices, as what we eat directly affects our health, hormones, and overall well-being.
(5) Avoid Large Meals Before Bed
Typically, the body releases growth hormone during the night. Consuming food, especially high-carbohydrate or high-protein meals, before bedtime can trigger insulin release, potentially inhibiting the production of GH. While there is limited research directly supporting this theory, insulin levels tend to decrease 2-3 hours after eating. Therefore, it is advisable to avoid high-carbohydrate and high-protein meals 2-3 hours before bedtime.
(6) GABA
GABA (Gamma-Aminobutyric Acid) is an amino acid that functions as a neurotransmitter in the brain and aids in sleep regulation. Interestingly, it has also been linked to an increase in growth hormone levels. One study found that GABA supplements helped increase GH levels by up to 400% during rest and 200% after exercise. GABA may promote GH secretion by improving sleep quality, as GH levels are closely associated with deep sleep. However, it's worth noting that the duration of increased GH secretion induced by GABA supplements is relatively short-term, and the long-term effects are less clear
(7) High-Intensity Exercise
Exercise is one of the most effective ways to significantly increase growth hormone levels. The quantity of growth hormone released depends on the type of exercise, the nutrition consumed during the exercise period, and individual body characteristics. When we look at the graph below, we can observe that weightlifting with short rest periods between sets results in a substantial increase in growth hormone secretion
Exactly, the process of metabolism and the release of lactic acid during high-intensity exercise contribute significantly to the substantial increase in growth hormone levels. However, it's worth emphasizing that all types of exercise can help boost growth hormone levels to some degree.
Whether you choose to engage in activities like sprinting, interval training, weightlifting, or circuit training, they all have the potential to increase growth hormone levels and enhance fat-burning rates. Exercise is the primary means by which we can actively and significantly elevate growth hormone levels in the short term.
Furthermore, in the long term, regular exercise not only helps with hormone regulation but also aids in reducing body fat, leading to an overall improvement in hormonal balance. Therefore, exercise remains a fundamental choice for enhancing growth hormone levels and promoting overall health.
(8) Beta-Alanine and Sports Drinks
Certain types of supplements can help increase growth hormone levels during exercise. Research has shown that consuming 4.8 grams of Beta-Alanine before exercise can increase exercise capacity by 22%, double energy levels, and raise growth hormone levels compared to a group that did not take Beta-Alanine before exercising. Additionally, there is research suggesting that sports drinks containing sugar can elevate growth hormone levels, particularly towards the end of a workout. However, it's important to note that if you're trying to reduce fat, you may not benefit significantly from increased growth hormone levels.
Studies have also found that both carbohydrate-containing and carbohydrate-free protein shakes can increase growth hormone levels during exercise.
(9) Improve Sleep Quality
Growth hormone is predominantly released during the sleep cycle, following our circadian rhythms. Circadian rhythms depend on our biological clock. When we look at the graph below, we can see that the circadian rhythm reaches its peak just before midnight and gradually decreases during the morning.
Therefore, it's crucial to prioritize high-quality sleep to maximize growth hormone production. Ensuring that you have a consistent sleep schedule, creating a conducive sleep environment, and engaging in relaxation techniques before bedtime can all contribute to better sleep quality and, consequently, more effective growth hormone secretion.
Research has found that poor-quality sleep can reduce growth hormone production, but getting deep, restful sleep can promote long-term growth hormone secretion. Here are some tips to help improve your sleep quality:
- Avoid using electronic devices emitting blue light before bedtime.
- Read a book in the evening to relax your mind.
- Maintain a comfortable temperature in your bedroom.
- Avoid consuming caffeine in the late afternoon and evening.
By following these sleep hygiene practices, you can enhance the quality of your sleep, which, in turn, can contribute to better growth hormone levels over the long term
(10) Melatonin
Melatonin is a hormone that plays a crucial role in regulating sleep and blood pressure. Melatonin supplements have become popular for aiding in easier sleep onset, improving sleep quality, and increasing sleep duration. While the quality of sleep has a positive impact on growth hormone levels, research has also found that melatonin directly helps boost growth hormone production. The use of melatonin is safe and non-toxic, but it can potentially alter brain chemicals, so it's advisable to consult a doctor before using this supplement.
To achieve the best results, it is recommended to take melatonin in doses ranging from 1-5 milligrams about 30 minutes before bedtime. Start with a lower dose and gradually increase it later if needed.
(11) Other
There are various supplements that can help increase growth hormone levels:
Glutamine: Taking 2 grams of glutamine can increase growth hormone levels by 78% in a short period.
Creatine: Consuming 20 grams of creatine can result in a noticeable increase in growth hormone levels that lasts for 2-6 hours.
Ornithine: Research has shown that taking ornithine supplements after exercise for 30 seconds can lead to higher growth hormone levels.
L-dopa: In individuals with Parkinson's disease, taking 500 milligrams of L-dopa can increase growth hormone levels within 2 hours.
Glycine: Studies have found that glycine can enhance exercise performance and boost growth hormone levels during short periods.
While these supplements can increase growth hormone levels, the effects are typically short-term
