The Suddenly Slim diet is safe if the consumer follows the guidelines and doesn't have any blood sugar or heart problems, according to LoveToKnow Diet. Individuals should consult their doctors before starting the Suddenly Slim diet.
The Suddenly Slim diet includes a 10-day period of light eating, so consumers with diabetes are advised against this diet, according to LoveToKnow Diet. Those with cardiac problems are also advised to avoid this diet because Suddenly Slim uses Ephedra, which is a stimulant that increases heart rate and blood pressure. The FDA does not endorse the use of Ephedra for these reasons. Before starting Suddenly Slim, individuals should have the diet approved by their doctors.
