Pointing in the same direction, the consumption of DAG together with alpha linoleic acid (ALA), a fatty acid undergoing easier beta oxidation as opposed to palmitic, stearic, oleic, or linoleic acid 207,208,209, resulted in excellent outcomes on body weight and visceral fat loss 203,210,211. The use of supplements claimed to “burn” fat is widespread, but only some of these have been proven to effectively and safely play a beneficial role on fat metabolism in preclinical studies. On the other hand, two different metanalyses showed that L-C supplementation can significantly decrease body weight and fat mass, although a decreased effect over time was reported 193,194.

Adding fiber supplements to meals can support weight loss efforts by improving digestion and preventing overeating. Study arms consisted of 5 to 105 participants, with a follow-up range of 3-24 weeks. Acupuncture is a traditional Chinese practice that involves placing small needles, with or without electrical stimulation, at various points in the body in order to adjust physiological functions and address numerous ailments (40). The most common reason for full-text exclusion was study type (i.e., commentary, editorial, non-randomized study).

A successive placebo controlled RCT evaluating the effects of consumption of 4.5 mg/day of spirulina extract in addition to a physical exercise program for six weeks on 45 overweight and obese men did not find any significant changes in anthropometric parameters, whereas it confirmed the lipid lowering effects . A recent metanalysis investigated the effects of spirulina supplementation on body weight reduction, including only five RCTs, published between 1996 and 2018, and 278 patients overall, consuming doses of spirulina between one and 4.5 g/day, for a duration from six to 12 weeks. A preclinical study investigating the anti-obesogenic effect of caralluma showed that rats supplemented with it reported a significant reduction in food intake, an inhibition of body weight, liver weight and fat mass gain . These results suggest that, although guar gum can lower cholesterol levels and improve insulin sensitivity compared with placebo , it seems not to be effective in lowering body weight and it should therefore be administered together with appropriate dietary manipulation. Another trial conducted in patients with T2D confirmed that a much smaller supplementation of KRG (100–200 mg/day) had a positive impact on glucose levels, despite failing to induce significantly more weight loss compared to placebo . Decreased intracellular calcium concentrations, in turn, might increase fat breakdown and discourage fat accumulation in these cells . First, high calcium intakes might reduce calcium concentrations in fat cells by decreasing the production of parathyroid hormone and the active form of vitamin D. The Recommended Dietary Allowance (average daily level of intake sufficient to meet the nutrient needs of 97%–98% of healthy individuals) for calcium ranges from 1,000 to 1,300 mg/day for children and adults age 4 years and older.

They work by increasing your body’s temperature to support thermogenesis, or your body’s ability to burn fat for fuel. We recommend analyzing all of the ingredients to get an idea of how the product can support your weight loss goals.

They recommend taking one capsule with breakfast and one capsule with lunch for the first 3–4 days to see how your body will react. Lastly, ALA metabolism products, eicosapentaenoic acid and docosahexaenoic acid, were able to induce adipocytes apoptosis, suppress appetite and enhance fat oxidation and energy expenditure in animal models, while human studies confirmed its potential benefit only in combination with exercise and hypocaloric diets . Further studies are needed to confirm the results seen in animal studies and to elucidate the mechanisms supporting weight loss in humans. The daily caloric intake, calculated from 24-h food recalls, decreased at four weeks in both groups and increased to baseline levels at week 8, suggesting an effect on weight loss independent of caloric intake. If its anti-obesity properties have been extensively demonstrated in animal models, only few human studies showed positive results regarding weight reduction .

Unfortunately, no over-the-counter weight loss vitamin or supplement is going to magically help you slim down. Losing body fat, including on the abdomen, requires a caloric deficit. In addition to their role in weight management, probiotics offer numerous other health benefits. In addition to its weight management benefits, fiber offers several other health advantages. By enhancing satiety and improving digestive health, fiber aids in weight management. There is considerable heterogeneity in trial design, bias, efficacy, and duration, suggesting a need to develop trials accounting for methodological flaws. The importance of an academic partnership with industry to conduct well-designed, randomized, double-blinded controlled trials of sufficient duration to demonstrate efficacy of each category would be helpful. Studies were heterogeneous and participants may not necessarily be representative of the typical patient presenting for weight loss. However, navigating the world of dietary supplements can be daunting, given the overwhelming amount of information and the promises made by manufacturers. Among the myriad of options available, natural supplements have gained traction as potential aids in the weight loss journey. While weight loss supplements may offer some benefits, they should be considered a complementary tool, not a primary solution. If you decide to explore weight loss supplements, proceed with caution and do your research. Whey protein, in particular, has been shown to help with weight loss and improve body composition. The above is just a sampling of available research on how protein can assist with weight loss. Again, I want to point out that a probiotic is much more than a weight loss aid. In a 2010 trial14, researchers concluded that probiotic supplementation reduced abdominal fat by an average of 4.6% from baseline across all participants. Fiber is important for more than weight loss, though, so it’s not a bad idea to supplement regardless if you are not currently meeting the recommended intake. Glucomannan is in many popular weight loss pills, including Leanbean and Trimtone. If it’s warranted to take a supplement, we have a guide to the best B12 supplements. According to the Cleveland Clinic27, deficiency in vitamin B12 can bring about symptoms such as intense fatigue, feeling very weak, feelings of depression and irritability, and gastrointestinal problems like nausea and diarrhea. Magnesium supplements are generally recognized as safe, so it’s worth a shot (first talk to your doctor if you have any health conditions). So we know that poor sleep can mean poor food choices; magnesium may help improve sleep; and magnesium is important for many other body functions. Additionally, the review reports data from intervention studies that suggests sleep deprivation can lead to more snacking behavior, especially if sleep restriction is recurrent (multiple nights in a row). Further, green tea is proven to be safe, with few inconsistent side effects or adverse events 26,27. Commercially available obesity medication orlistat exerts its weight lowering effect through the intestinal inhibition of fat absorption. So, herein, we aimed at summarizing available evidence regarding supplements most likely to be effective in aiding weight loss, classifying them by their purported mechanism of action.

Vitamin D from both foods and dietary supplements is safe at recommended intakes of 600–800 IU/day for adults .

The efficacy of green tea or GTE has been extensively researched, and for the most part, the results are favorable. EFSA assessed the amount of EGCG delivered in green tea infusions and found a wide range, from 2.3 to 203 mg/100 g (~3.3 fl oz) infusion . A review of the Mintel GNPD indicates products with GTE or EGCG, when consumed under the manufacturers’ recommended servings ranged from 100–1200 mg/day and 27–350 mg/day, respectively. FDA “When formulated and marketed appropriately, caffeine can be an ingredient in a dietary supplement that does not present a significant or unreasonable risk of illness or injury” . The evidence on the effect of caffeine on weight management is mixed, with some data suggesting caffeine might have benefits in supporting healthy blood glucose levels. Unlike pharmaceutical drugs, manufacturers of dietary supplements are not required to provide evidence of efficacy or safety before bringing products to market. Although some small studies have suggested a weight loss benefit, the overall body of evidence is inconclusive. Rich in antioxidants known as catechins, green tea extract is believed to enhance metabolic processes and promote fat oxidation. Thus, while caffeine can support weight loss efforts, it should be part of a broader strategy that includes dietary changes and physical exercise. While supplements like fat burners to enhance weight loss may offer modest benefits, they should never replace a healthy lifestyle. Each serving of Leanbean is filled with garcinia cambogia, green tea, green coffee, turmeric, cayenne pepper, konjac, and chromium. LeanBean is the trendiest natural weight loss supplement for women. When you are faced with the decision to choose the right weight loss supplement, it’s important to note that this depends on your specific goals. A review of published and unpublished studies concluded that bitter orange extract and p-synephrine increase metabolism and energy expenditure, but there is a need for long-term efficacy studies in humans. Several studies have examined multi-ingredient products containing bitter orange. Due to its sympathomimetic properties, bitter orange gained popularity as a weight-loss supplement after ephedra was banned because of adverse cardiovascular effects. In addition, caffeinated green tea may worsen symptoms in patients with anxiety, diarrhea, and dysrhythmias and increase intraocular pressure in glaucoma. Overall, moderate-quality evidence suggests that DAG at a dosage of 1.1–1.2 g/day is effective in reducing body weight in both healthy and diabetic subjects compared to TAG, leading to a reduction in cardiovascular risk, with no adverse events being reported, and its use as a weight loss supplement could therefore be recommended. For instance, Mohammadi et al. did not find a statistically significant difference in anthropometric parameters such as BMI, weight and total body fat of obese patients receiving a supplementation of curcumin at a dosage of 1 g/day compared to placebo . A double-blind, randomized, placebo-controlled trial reported that curcumin administration is well-tolerated and can positively influence weight management in overweight people by increasing weight loss (from 1.88% to 4.91%), and reducing body fat percentage (from 0.70% to 8.43%) . Several studies have evaluated how green coffee extracts, rich in both CGA and caffeine, have proven effective in inducing weight loss . Consider berberine an option for you to lose some weight and reduce your blood sugar levels. One approach may be to start by taking berberine for three months, then have your blood tested to see if your A1C went down and check your weight again. That’s true of other supplements as well, which is why some practitioners recommend taking periodic breaks from supplements. Side effects of berberine aren’t common, and the benefits of the supplement typically outweigh side effects. In 2016, FDA issued 36 public notifications warning consumers not to purchase specific weight-loss products because they contained a hidden drug ingredient—often sibutramine, a weight-loss medication that was withdrawn from the U.S. market in 2010 because of safety concerns . Furthermore, many weight-loss supplements contain multiple ingredients that have not been adequately tested in combination with one another. In some cases, the active constituents of botanical or other ingredients promoted for weight loss are unknown or uncharacterized .
