Interpreting the results Clinically proven weight loss supplements these studies is complicated by the fact that bitter orange is almost always combined with other ingredients in weight-loss supplements. Much of the research on probiotics and its influence on the gut microbiota and obesity has been in mice, and the results have been promising. Dairy products, in particular, might contain additional components that have even greater effects on body weight than their calcium content alone would suggest [ 60].

Clinically proven weight loss supplements -

How it works: Conjugated Linoleic Acid CLA , a type of fat found in meat and dairy products, may reduce appetite, boost metabolism , and help with fat burning, says Sopczak. What the research says: A review of 18 studies found taking CLA was associated with losing 0.

Overall effectiveness: According to the NIH, CLA might help you lose a "very small amount" of weight as well as body fat. Side effects: CLA can cause some digestive side effects like constipation and diarrhea, and if taken over the long-term, Sopczak says it may increase your risk of fatty liver disease and insulin resistance.

How it works: Guar gum, a type of fiber extracted from guar beans, may help you feel fuller longer, thereby reducing how much you eat, says Sopczak. What the research says: A review of 20 trials found taking a guar gum supplement resulted in less than 1 pound of weight loss — and that the risk of adverse events like abdominal pain, diarrhea, gas, and cramps outweighed any potential benefits.

Overall effectiveness: The NIH has concluded that taking guar gum "probably doesn't" help you lose weight. Guar gum may help to control appetite, but this same effect could potentially be achieved without unpleasant side effects simply by eating more foods high in soluble fiber such as oats, barley, apples, and oranges.

Side effects: Guar gum may cause gastrointestinal symptoms or trigger an allergic reaction in some people, says Sopczak. How it works: Extract from the bitter orange fruit contains synephrine, a compound with stimulant effects believed to reduce appetite and increase fat burning.

What the research says: A review of 23 studies totaling about participants found nine of the studies showed that synephrine may cause an increase in metabolic rate, suggesting it may be beneficial in weight management.

However, researchers said well-controlled, longer-term studies involving only bitter orange extract are needed since about two-thirds of subjects also consumed caffeine, which may have impacted results.

Overall effectiveness: While bitter orange extract may slightly suppress appetite and increase how many calories you burn, the NIH says the word is still out on whether it can actually help you lose weight. Research on the potentially harmful effects of bitter orange is inconclusive — some studies found bitter orange raised heart rate and blood pressure , while others found it didn't have cardiovascular effects at common doses up to milligrams.

How it works: The active ingredient in ephedra, an herb that comes from an evergreen shrub, is a known stimulant that may increase your metabolic rate, thus helping you to burn more calories and ultimately lose weight.

What the research says: A review of nine studies totaling overweight or obese participants found products containing ephedrine were associated with around 4. Overall effectiveness: Researchers have struggled to discern the effectiveness of ephedra since there aren't any long-term studies and most studies have also included caffeine , which is known to support weight loss.

Ultimately, the risks of these supplements seem to far outweigh the potential benefits. Side effects: The FDA banned this highly controversial supplement in because it can increase heart rate and blood pressure , and in rare cases, cause heart attack , stroke , or even death.

How it works: Chitosan is a sugar mainly derived from the outer skeletons of crustaceans. According to Sopczak, it is said to turn into a gel-like substance in the stomach which then binds to fat in the intestines , but evidence of this is inconclusive.

What the research says: A review of 14 trials totaling 1, overweight or obese subjects found chitosan supplements slightly reduced body weight — by about 2.

Overall effectiveness: According to the NIH , chitosan does not bind to nearly enough fat to result in significant weight loss. Side effects: Chitosan is generally considered safe , but Sopczak says possible side effects include upset stomach, nausea, bloating, and constipation.

How it works: The mineral chromium is believed to increase lean muscle mass while reducing body fat. It also helps insulin perform properly , which Sopczak says helps the body process carbs, fat, and protein more effectively. What the research says: A review of nine trials with a total of participants found overweight and obese adults who took chromium picolinate a supplemental form of chromium lost an average of about 2.

Researchers determined this amount of weight loss was of "debatable clinical relevance" and that more "reliable evidence" is needed to verify the efficacy of these supplements.

Overall effectiveness: The NIH says chromium may help you lose a "very small amount" of body weight and fat. Less than 2. Side effects: In supplement form, high doses of chromium can interfere with insulin and other diabetes medications.

This supplement should also be avoided by those with kidney or liver problems , or with anemia. Kidney damage, worsened depression or anxiety, and irregular heartbeat have been reported in rare cases.

People with liver or kidney problems , or people with anemia, should not take chromium without first talking to their doctor. While there's a chance some of these supplements — like green coffee extract, CLA, and chromium — may help support your weight loss efforts, Kumar says there still aren't enough randomized controlled trials to prove they result in significant, sustained weight loss on their own.

Experts agree none of these products will work miracles without healthy changes to your diet and exercise habits. Because of the potential for interactions with medications and side effects, you should always talk to your health care provider before trying any of these supplements.
