WebMD recommends managing weight loss at a rate of 3 to 5 pounds per week. Losing 30 pounds in 30 days is only slightly more aggressive than the recommended range and is likely possible for most people who are strongly committed to a consistent workout regimen and healthy diet. A healthy fitness regimen incorporates a balance of aerobic exercise and muscle building using a mixture of free weights, body weight and controlled movement machines.
WebMD warns that rapid weight loss may indicate unhealthy habits such as excessive exercise or extreme dietary restrictions. It is important to stick to healthy habits and allow weight to burn off at a rate that is most natural to the body. These rates vary according to each person's metabolism.
