Sports food for weight loss: side effects

Chapter 1: Understanding of sports nutrition for weight loss: Fundamentals and mechanisms of action

Sports nutrition for weight loss is a wide range of food additives designed to optimize metabolism, increase energy consumption, suppression of appetite and maintaining muscle mass in the process of weight loss. It is important to understand that these products are not a magic tablet, but only an effective tool that should be used in combination with a balanced diet and regular physical exercises. Understanding the mechanisms of action of these additives is critical of assessing potential side effects and minimizing risks.

1.1. Sports diet categories for weight loss:

The sports nutrition market offers many products that can be classified according to their main action and composition:

• Fat -burners (Thermogens): These products are aimed at accelerating metabolism and increasing thermogenesis – the process of heat generation by the body, which leads to the burning of calories.
• L-Carnitin: An amino acid that plays a key role in transporting fatty acids to mitochondria, where they are used to obtain energy.
• Appetite suppressors (Appetite Suppressants): These additives help control the feeling of hunger, reducing calorie intake.
• Carbohydrates and fat blockers (Carb & Fat Blockers): Designed to reduce the absorption of carbohydrates and fats in the intestines.
• Protein supplements (Protein Supplements): Serum protein, casein, soy protein and other forms of protein help to maintain muscle mass during the diet and contribute to saturation.
• CLA (Conjugated Linoleic Acid): Fatal acid, which is believed to reduce the fat mass and increase muscle mass.
• BCAA (Branched-Chain Amino Acids): Amino acids with an extensive chain that support muscle tissue and help restoration after training.
• Vitamin-mineral complexes (Vitamin & Mineral Supplements): Provide the body with the necessary trace elements that can be missed when calories are limited.
• Diuretics: Diuretics: They help to remove excess fluid from the body, which can temporarily reduce weight.

1.2. Action mechanisms:

Each sports nutrition category works in its unique mechanism:

• Fat -burners (Thermogens):
  • Nervous system stimulation: Components, such as caffeine, synephrine and green tea extract, stimulate the central nervous system, increasing the release of adrenaline and norepinephrine. This leads to an increase in heart rate, blood pressure and metabolism.
  • Thermogenes: Increasing heat production by activating brown adipose tissue and enhancing fat oxidation processes.
• L-Carnitin:
  • Transportation of fatty acids: L-carnitin transfers long-chain fatty acids through the mitochondrial membrane, where they are oxidized and turn into energy.
• Appetite suppressors (Appetite Suppressants):
  • Increase in a sense of saturation: Soluble fibers, such as glucomannan and psillium, absorb water in the stomach, creating a feeling of satiety and reducing the desire to eat.
  • Influence on hormones of hunger: Some additives, such as 5-HTP, can affect the level of serotonin, a neurotransmitter that regulates mood and appetite.
• Carbohydrates and fat blockers (Carb & Fat Blockers):
  • Inhibition of enzymes: Some ingredients, such as phaseolamine (white beans extract), inhibit the enzyme alpha amylase, which is responsible for the breakdown of carbohydrates. Orlistat blocks lipaza, an enzyme that breaks down fats.
  • Binding with fats and carbohydrates: Some additives contain substances that are associated with fats and carbohydrates in the digestive tract, preventing their absorption.
• Protein supplements (Protein Supplements):
  • Saving muscle mass: High protein consumption helps to prevent muscle loss during a calorie diet.
  • Increase in a sense of saturation: Protein has a high saturation index, which helps to control the appetite.
  • The thermal effect of food: Squirrel digestion requires more energy than digestion of carbohydrates or fats, which can slightly increase calorie consumption.
• CLA (Conjugated Linoleic Acid):
  • Influence on fat metabolism: It is believed that CLA can increase lipolysis (splitting of fats) and reduce lipogenesis (fat formation).
  • Improving the composition of the body: Some studies show that CLA can help reduce fat mass and increase muscle mass.
• BCAA (Branched-Chain Amino Acids):
  • Muscle tissue support: BCAA, especially leucine, play an important role in the synthesis of protein and prevent the decay of muscle tissue.
  • Reducing muscle fatigue: BCAA can reduce fatigue during training and speed up recovery after them.
• Vitamin-mineral complexes (Vitamin & Mineral Supplements):
  • Filling up deficits: Provide the body with the necessary trace elements that can be limited in a diet.
  • Maintenance of health: Vitamins and minerals play an important role in many body functions, including energy metabolism, immunity and bone health.
• Diuretics: Diuretics:
  • Front elimination: They contribute to an increase in diuresis (urine discharge), which leads to a temporary reduction in weight due to fluid loss.

1.3. Factors affecting effectiveness:

The effectiveness of sports nutrition for weight loss depends on many factors, including:

• Individual characteristics of the body: Genetics, age, gender, state of health and metabolism affect how the body reacts to additives.
• Diet: A balanced calorie deficit is a key factor in success.
• Physical activity: Regular training enhance the effect of additives and promote fat burning.
• Dosage and reception mode: The correct dosage and the time of receiving additives are important for achieving optimal results.
• Quality product: It is important to choose products from trusted manufacturers to guarantee their quality and safety.
• Combination of additives: Some additives can synergically enhance each other’s effect, while others can conflict.
