No fat-burning supplement will help you directly burn fat, but they will give your body the nutrients it needs to ensure an effective and efficient natural fat-burning process. So while they do work, they aren’t a magic solution that burns fat without any effort on your part. Many people suggest that 80-90% of the fat-burning process is dependent on your diet and exercise routine, while fat-burning supplements help with the other 10-20%. When utilized properly and as-directed, supplements can certainly help — but there’s more to it than that.
