Little evidence supports that chia seeds help anyone lose weight. In a 12-week study at Appalachian State University, participants consumed 50 grams of chia seeds daily. Researcher David Nieman, who has a doctorate in public health, found no change in appetite or body weight, WebMD explains.
Similar results were found in a review of scientific evidence. In two clinical trials, one showed a heart benefit, but neither showed any effect on weight loss, states WebMD.
However, chia seeds are concentrated food that can supplement the diet. They are unprocessed, whole-grained and contain omega-3 fatty acids, carbohydrates, protein, fiber, antioxidants and calcium. In the book "You Staying Young," Michael Roizen, M.D. and Mehmet Oz, M.D. state that chia seeds have higher antioxidant activity than any whole food, including blueberries, and recommend taking 20 gram daily doses twice a day, says WebMD.
