使用替尔泊肽减肥，多久能看到疗效？

Core Viewpoint - The article discusses the effectiveness and factors influencing the weight loss effects of the drug Tirzepatide, emphasizing that while it can lead to significant weight loss, the results may vary based on individual circumstances and lifestyle choices [5][8]. Summary by Sections Weight Loss Efficacy - Tirzepatide has a half-life of 5 days, and it takes about 30 days to be eliminated from the body after discontinuation. A safe weight loss rate is suggested to be 1 to 2 pounds per week [5]. - Initial weight loss may not be noticeable in the first few weeks, but by week 12, participants in the SURMOUNT-1 trial showed an average weight reduction of about 8% from their initial weight [5]. - By week 24, weight loss percentage stabilizes around 12-15%, and with a combination of healthy diet and regular exercise, significant results can be achieved. By 72 weeks, average weight loss can range from 16% to 22.5% of initial weight [8]. Factors Affecting Efficacy - Metabolism: Conditions like fatty liver and diabetes complicate weight loss due to metabolic dysfunction, potentially delaying the drug's effectiveness [9]. - Age: Metabolism slows with age, affecting the drug's action speed. Research indicates a decline of less than 1% per year after age 60 [10]. - Gender: Women may experience better weight loss results with Tirzepatide compared to men, likely due to differences in body fat percentage and insulin resistance [12]. - Concurrent Medications: Certain medications, such as steroids and antidepressants, can lead to weight gain, potentially diminishing the weight loss effects of Tirzepatide [13]. - Dosage and Treatment Plan: Higher doses may enhance effects and side effects, but do not always guarantee better results. Finding the right dosage is crucial [14]. - Genetics: Genetic factors can influence individual responses to Tirzepatide, leading to variability in effectiveness [15]. - Lifestyle Factors: Combining Tirzepatide with lifestyle changes, such as exercise and a balanced diet, yields the best weight loss outcomes [16].
