Metabolism and TEF<\/strong> (Thermic Effect of Food)<\/h3>\n\n<p>The belief that frequent, small meals &#8220;boost metabolism&#8221; is a myth. <strong>The Thermic Effect of Food (TEF)<\/strong> \u2014 the energy expended on digestion \u2014 depends on total calorie intake.<\/p>\n\n<ul class=\"wp-block-list\">\n<li>TEF accounts for approximately 10% of total calories. Regardless of whether you consume 2000 kcal in one meal (200 kcal burned) or ten (10 x 20 kcal), the total for the entire day remains the same [1].  <\/li>\n\n\n\n<li>The International Society of Sports Nutrition (ISSN) states that increased meal frequency does not significantly increase thermogenesis or basal\/resting metabolic rate [2].<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\"><strong>2.

During fasting, despite high GH, IGF-1 levels often <strong>decrease or remain unchanged<\/strong> because the body is in an energy deficit. Thus, this increase in GH has, at best, an anti-catabolic effect, which is something, but promoting fasting as a magical way to gain muscle is false. <\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\"><strong>3.
