When we think about fitness, we often picture sweating it out in the gym, pumping iron and working our muscles to achieve that perfect body. But did you know that hormones play a vital role in muscle building and fat burning, and if they are not kept in balance, your hard work could be sabotaged? In this blog, we'll explore some of the essential hormones for achieving your fitness goals and show you how to keep them in balance naturally.

Insulin Insulin is a hormone that regulates blood sugar levels. When we eat, glucose gets stored as glycogen in our muscles and liver until they reach full capacity. After this point, any excess glucose will be stored as fat. Therefore, it is crucial to control our insulin levels through diet. Carbohydrates produce the most significant release of insulin, while fat has a minimal effect on blood sugar. Protein releases less insulin, but if we eat too few carbs, our body will convert more of the protein into sugar, which is not ideal for muscle repair and growth. To make the most of insulin, it's best to consume carbs after a workout when your muscles and liver stores are low.

Testosterone Testosterone is a hormone that plays a vital role in protein synthesis, which is essential for building muscle. Men naturally produce more testosterone than women, which is why women won't become bulky by lifting weights. To increase testosterone levels, we need to ensure we're getting enough vitamins and minerals like B, C, zinc and manganese. Additionally, our diet should contain plenty of fat, including saturated fat, which provides the cholesterol needed to synthesize testosterone. Heavy resistance training with short rest periods also stimulates testosterone production. Stress levels should be kept low, and training shouldn't be done every day. Alcohol should be avoided as it lowers testosterone, and painkillers should only be taken when necessary. Finally, it's essential to lower levels of sex hormone binding globulin (SHBG), which stores testosterone, limiting the amount that is free to build muscle. This can be done through supplements of boron, magnesium and zinc, plenty of carbs, vitamin D, reducing fiber intake and limiting alcohol.

Human Growth Hormone Human growth hormone (HGH) is another hormone essential for muscle building, fat burning, and increased performance. It works alongside testosterone to build and strengthen muscles, regenerates bone and connective tissue to support increased muscle size, promotes a positive nitrogen balance, increases amino acid uptake, stimulates cartilage growth, enhances immune cell function and increases fat breakdown. To increase HGH levels, it's important to eat slow-releasing carbs, especially before sleep and exercise, go to bed on an empty stomach, get a good night's sleep, take naps when needed, carry out high-intensity resistance training, eat frequently, and use compound movements. Reducing sugar intake can also help.

DHEA Finally, DHEA is a steroid hormone that is naturally made in the adrenal glands but can also be taken as a supplement. It's converted into male and female sex hormones and is essential for building muscle, protecting against hormone imbalances, and age-related declines in hormone levels. It can also aid sporting performance, enhance libido, promote weight loss, and support the immune system. Supplements of DHEA may also be helpful with conditions such as Alzheimer's, depression, MS, Parkinson's, fatigue, menopausal symptoms and chronic fatigue syndrome.
