Rapid Slim it sucks but it's good for you and afterwards you'll feel great plus out of the 8 people that I know personally doing the diet only one has gotten keto flu and she cheated on her diet twice in the first week so no wonder my mom is very silly but I love you mom but now no longer running on sugar you will enter ketosis and produce ketones which take fat and convert it into energy so basically at this point you are always burning fat for energy even when you are sleeping you will also help starve off most cancers from happening or progressing you will slow and reduce insulin.
