Some supplements contain ingredients that may help reduce appetite and cravings, making it easier to consume fewer calories and maintain portion control. Increased Metabolism: Certain supplements can boost your metabolism, potentially leading to increased calorie burn and, consequently, weight loss. Common ingredients for this purpose include caffeine and green tea extract. Enhanced Fat Burning: Fat burners are a subset of weight loss supplements designed to increase the body's ability to burn fat. These often contain ingredients like thermogenic compounds or L-carnitine. Energy Boost: Many weight loss supplements contain stimulants like caffeine, which can provide a temporary energy boost. This increased energy can help you stay more active and potentially burn more calories during exercise. Nutrient Support: Some weight loss supplements include essential nutrients or vitamins to ensure you're getting adequate nutrition while on a calorie-restricted diet. Reduced Water Retention: Certain supplements may help reduce water retention, leading to a temporary decrease in body weight. However, this is usually not indicative of actual fat loss. Improved Insulin Sensitivity: Some supplements, such as chromium and berberine, may help improve insulin sensitivity, which can be beneficial for individuals with insulin resistance or those at risk of type 2 diabetes. Mood Enhancement: Some weight loss supplements contain ingredients that can improve mood and reduce stress, potentially helping to prevent emotional eating.
