Obesity Epidemic
The prevalence of obesity has reached epidemic proportions, with over 20% of the global population affected. It is projected that by 2030, one billion people will be classified as obese. Obesity is associated with a myriad of complications, including type 2 diabetes, dyslipidemia, hypertension, and cardiovascular diseases. To combat this growing health concern, various approaches to obesity management have been explored, including lifestyle modifications and pharmacological interventions.
One potential intervention that has gained attention is the use of Acetyl L-Carnitine (ALC) or L-Carnitine Tartrate. ALC is a compound that plays a crucial role in lipid metabolism by facilitating the transport of long-chain fatty acids to the mitochondria for beta-oxidation. Additionally, ALC has been reported to improve insulin resistance and potentially decrease appetite and food intake through its effects on the hypothalamus. (6)
Clinical studies investigating the effects of ALC supplementation on obesity-related indices have yielded mixed results. Some studies have reported weight-reducing effects, while others have shown no significant impact. A previous meta-analysis conducted by Pooyandjoo et al. included six studies and demonstrated that ALC supplementation significantly decreased body weight and BMI compared to controls. However, this analysis may be considered insufficient due to the limited number of studies included.
To address these limitations and provide a more comprehensive understanding of the efficacy of ALC, we performed a systematic review and meta-analysis of 35 articles that had not been previously considered. Additionally, a dose-response analysis was conducted to explore potential non-linear associations between ALC dose and obesity-related indices. The findings of this study aim to provide clearer evidence regarding the therapeutic potential of ALC in the management of obesity.
Methods
Our meta-analysis followed the recommended guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The PICOS model was applied to define the study’s criteria: Population (adult subjects), Intervention (ALC supplementation), Comparison (matched control group), and outcomes (weight, BMI, waist circumference, body fat percentage, and body fat mass). Randomized controlled trials (RCTs) that reported these outcomes were included in the analysis. (7)
The search strategy involved an electronic search of online literature databases, including Medline (PubMed), Scopus, and Google Scholar, up until November 2018. After initial screening, 6607 unduplicated studies were considered for further evaluation. Unrelated papers were eliminated based on title and abstract analysis, resulting in the exclusion of 6535 studies. After a full-text review, an additional 29 studies were excluded. The final analysis included a total of seven eligible RCTs.
Results
The pooled data from the seven included studies demonstrated that ALC supplementation resulted in significant improvements in muscle soreness (MS) at multiple follow-up time points (0, 24, 48, 72, and 96 hours) compared to placebo. Additionally, ALC significantly reduced levels of creatine kinase (CK), myoglobin (Mb), and lactate dehydrogenase (LDH) at the 24-hour follow-up period. However, no significant effects were observed beyond this time frame. These results suggest that ALC supplementation can effectively alleviate delayed-onset muscle soreness (DOMS) and reduce markers of muscle damage.
In terms of weight-related outcomes, ALC supplementation showed significant effects on weight, BMI, waist circumference (WC), and fat mass. However, no significant impact was observed on body fat percentage. These findings indicate that ALC has the potential to be used therapeutically for weight management in obese and overweight adults.
Discussion
The results of this meta-analysis support the notion that ALC supplementation can lead to improvements in weight-related outcomes and muscle soreness. The mechanisms underlying these effects may be attributed to ALC’s role in lipid metabolism and its potential impact on insulin resistance and appetite regulation. However, it is important to note that the observed effects were primarily seen in resistance training groups and untrained populations. Further research is needed to explore the effects of ALC supplementation in different populations and in response to different types of mechanical or chemical damage.
It is worth mentioning that the dose-response analysis conducted in this study did not reveal any significant non-linear associations between ALC dose and obesity-related indices. This suggests that the efficacy of ALC supplementation may not be strongly influenced by the dosage administered.
Overall, the findings of this comprehensive meta-analysis support the potential therapeutic use of ALC in the management of obesity. However, further research is warranted to elucidate the optimal dosage, long-term effects, and potential side effects of ALC supplementation. A pivotal phase III trial is needed to validate these findings and provide more precise recommendations for its therapeutic use.
Supplementation
In conclusion, this systematic review and meta-analysis provide substantial evidence supporting the efficacy of ALC supplementation in improving weight-related outcomes and alleviating muscle soreness. The findings suggest that ALC has the potential to be used as a therapeutic compound in the management of obesity. However, further research is required to fully understand the optimal dosage, long-term effects, and potential side effects of ALC supplementation. These findings contribute to the growing body of literature on complementary therapies for weight loss and provide health workers with more precise recommendations for the therapeutic use of ALC.
