Approximately 20% of the weight lost during dieting can come from lean body mass, which includes muscle, rather than just fat. While the body prefers to burn fat for fuel, certain factors can force it to break down muscle tissue, hindering your progress and slowing your metabolism.

Did you know that carbohydrates are your body's main source of energy, fueling the brain, muscles, and organs? An insufficient supply of carbohydrates can disrupt these vital functions, leading to significant harm across your entire body.

Over half of the weight lost by dieters can be regained within two years, partly due to a decrease in metabolically active muscle mass. Therefore, it's critical to know how to tell if your body is burning muscle so you can adjust your strategy for sustainable, healthy weight loss.

According to research published in the American Journal of Clinical Nutrition, athletes on low-carb diets have significantly lower muscle glycogen stores, leading to a drop in performance. This critical energy deficit is precisely what happens if you workout without eating carbs, and it can have profound effects on your body and fitness goals.

Studies indicate that prolonged and severe calorie restriction can decrease your body's metabolic rate significantly, a process known as metabolic adaptation. But what happens when you eat below your RMR, the absolute minimum calories needed for basic functions? The effects can be far-reaching and detrimental to your health, impacting everything from your energy levels to your long-term metabolic health.

During the first 24 hours without food, your body breaks down stored glycogen for energy. But the process changes over time. So, does my body eat itself if I don't eat for longer periods? The answer is a complex breakdown of metabolic phases.

According to research published via the NIH, essential amino acid (EAA) deficiencies remain a significant nutritional problem, particularly among vulnerable populations like the elderly. So, what happens if you lack essential amino acids? The consequences can be systemic, affecting everything from your muscles and mood to immune function.

According to UNICEF, malnutrition, which includes severe protein deficiency, contributes to nearly half of all deaths in children under five worldwide. While severe protein deficiency is rare in developed countries, a consistently low intake can lead to serious health issues over time.

According to a systematic review published in PubMed Central, diets involving severe energy restriction over several weeks or months lead to clinically significant weight loss but also trigger substantial negative health and performance implications. This article delves into the profound effects that intentionally or unintentionally consuming insufficient calories can have on the body and mind.

According to research published by the National Institutes of Health (NIH), skeletal muscle is constantly undergoing a process of remodeling, with active individuals experiencing a protein turnover rate of around 1.2% per day. Protein is needed to sustain muscle mass, as it provides the essential building blocks for repair and maintenance.
