Using this method, it is possible to determine the somatotype of your physique. It measures the shape and composition of your body. The result is a three-digit number, each number designating endomorphic, mesomorphic and ectomorphic elements. The element values range from 1 (low) to 7 (high). A value sheet is used for getting results. From the finite number, we can then determine if our physique is more endomorphic (e.g. 6-2-2), mesomorphic (e.g. 3-5-2), or ectomorphic (e.g. 3-3-5). The result can also be used to determine which sport your physique is more suitable for. <span style=\"color: #ff6600;\">[18]<\/span><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>For a better idea, we present a Heath-Carter graph with values<span style=\"color: #ff6600;\"> [19]<\/span>:<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><img decoding=\"async\" src=\"https:\/\/wpstatic.gymbeam.com\/blog\/wp-content\/uploads\/mageblog\/Somatotype-chart-Heath-Carter-390x355.jpg\" alt=\"Genetics and its impact on muscle growth and weight loss\" title=\"Genetics and its impact on muscle growth and weight loss\"\/><\/figure><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">What causes someone to be born as an ectomorph and other as an endomorph?<\/h3>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>The most important genetically <strong>congenital traits<\/strong> that influence the physique&#8217;s somatotype are <span style=\"color: #ff6600;\">[9]<\/span>:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Physical features &#8211; height, length, width, muscle mass, fatty tissue<\/li><li>Personality traits &#8211; emotionality, sociability<\/li><li>Sexual orientation<\/li><li>Mental disorders<\/li><\/ul>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Fat_distribution_and_genetics\"><\/span>Fat distribution and genetics<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><em>&#8220;I gain weight even if I drink a glass of water.&#8221;<\/em> The notorious <strong>sentence<\/strong>, which of course is a <strong>myth<\/strong>.

It is the result of research conducted on children and adults in the UK and Europe. As a result, some variation of the <strong>FTO gene<\/strong> was associated with excessive body fat, obesity, and type 2 diabetes.<span style=\"color: #ff6600;\"> [11]<\/span><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>However, this discovery cannot be taken as an <strong>&#8220;overweight judgment&#8221;<\/strong> Just because you have this variant of the FTO gene does not mean you will surely suffer from obesity. This variant rather causes <strong>a susceptibility to obesity<\/strong>. Research carried out on schoolchildren in Scotland shows a link between higher-weight children and the FTO variant of the gene. Tests showed that the FTO variant <strong>did not cause slow metabolism<\/strong>. The problem was the <strong>amount of high-calorie food<\/strong>. <span style=\"color: #ff6600;\">[12]<\/span><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>If you are not careful about your diet and sufficient movement, the FTO gene will be responsible for your weight gain. <strong>But there is no need to worry about excessive weight gain in a balanced diet and sport activity.<\/strong><\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/wpstatic.gymbeam.com\/blog\/wp-content\/uploads\/mageblog\/DSC08666.jpg\" alt=\"Genetics and its impact on muscle growth and weight loss\" title=\"Genetics and its impact on muscle growth and weight loss\"\/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_fats_vary\"><\/span>The fats vary<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>It should not be forgotten that fat is beneficial in our body. It depends on the amount of fat and its type. Our body contains three types of fat <span style=\"color: #ff6600;\">[10]<\/span>:<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Subcutaneous<\/strong> &#8211; located directly under the skin and on the muscle surface.

It cannot be felt or caught. However, its lack or surplus may cause health problems.<\/li><li><strong>Brown<\/strong> &#8211; the type of fat that <strong>maintains our body temperature<\/strong>.

Some directly and some only indirectly. <strong>Testosterone, growth hormone and insulin-like growth hormone<\/strong> are responsible for muscle strength and growth. <strong>Cortisol, adrenaline, norepinephrine and glucagon<\/strong> are responsible for fuel supply (glucose). <span style=\"color: #ff6600;\">[13]<\/span><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>The level of testosterone in a man&#8217;s body changes <strong>in the course of life<\/strong>. In addition, two men of the same age may not have exactly the same testosterone level.<\/p>\n<\/div>\n<\/div>\n\n\n\n<p>However, in 2011, researchers found that low testosterone levels may be caused by <strong>genetic predisposition<\/strong>. The genetic variants of SHBG (<em>sex hormone-binding globulin<\/em>) and the 10th chromosome are associated with low testosterone levels. Its low levels can cause cardiovascular disease, type 2 diabetes and others. However, why every man does not have the same testosterone level is a mystery to scientists so far. <span style=\"color: #ff6600;\">[14]<\/span><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>No less important hormone for muscle growth is <strong>growth hormone<\/strong>. However, it also affects the growth of the child. Its deficit is <strong>rather unusual<\/strong>, affecting 1 in 5,000 people.<span style=\"color: #ff6600;\"> [15]<\/span> The fact that you will probably gain fat more easily in old age must not be a reason for resignation. <strong>The more we know <\/strong>about our body, metabolism, or genes, the better we can direct our organism <strong>towards a healthy path.<\/strong><\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>All the combinations of information in our DNA <strong>make us original<\/strong>.

Still, whatever the proportion of cross-striated tissue types, <strong>motivation is more important<\/strong>. Genetics seems relentless, but the <strong>result is up to you<\/strong>. Remember, our body needs fat but only the right amount.
