Chia for Weight Loss

Can Chia Help You Lose Weight?

Chia (Salvia hispanica L.) is a flowering plant often marketed as a weight loss aid. Some proponents claim that chia can also protect against heart disease, stimulate the immune system, and improve nerve function.

Sold in whole-seed, oil, and capsule form, chia contains omega-3 fatty acids, fiber, and antioxidants. To date, however, there is little scientific evidence showing that chia can promote weight loss or offer any other health benefits.

The Science Behind Chia and Weight Loss

For a 2009 report from Reviews on Recent Clinical Trials, scientists gathered the available research on the health effects of chia. Although some studies showed "possible effectiveness" for several conditions (including high blood pressure, high cholesterol, and angina), the report's authors caution that there is limited evidence supporting the use of chia for any indication (including weight loss).

In a study published in Nutrition Research the same year, researchers assigned 90 overweight or obese adults to 12 weeks of treatment with chia seed or a placebo. Looking at study results, the researchers found no differences in body mass, inflammation, or blood pressure between the two treatment groups.

In 2007, another study published in Diabetes Care and involving 20 people with type 2 diabetes found that 12 weeks of treatment with chia helped reduce systolic blood pressure and inflammation but failed to produce changes in body weight.


There's some evidence that chia use may interfere with the effects of drugs taken for diabetes and high blood pressure. Consumption of chia may also lower your blood sugar levels.

It's important to keep in mind that supplements haven't been tested for safety and dietary supplements are largely unregulated.

In some cases, the product may deliver doses that differ from the specified amount for each herb. In other cases, the product may be contaminated with other substances such as metals. Also, the safety of supplements in pregnant women, nursing mothers, children, and those with medical conditions or who are taking medications has not been established.

Using Chia for Weight Loss

Due to the lack of supporting research, chia cannot be recommended as a weight loss aid. Adding whole chia seeds or chia oil to your diet may offer some health benefits, but it's important to consult your physician before taking chia capsules (or any other dietary supplement) in the effort to promote weight loss.
