i am currently on the “don’t diet” plan suggested by john berard. i am also using a thermogenic (xenadrine efx)and doing cardio for 45 min. 2-3 times a week. i am also working out four days a week. what is an acceptable amount of fat to burn each week without sacrificing even an ounce of muscle. i am also using 4ADEC to help with keeping muscle mass. i am at about 19% bf and trying to get down to 9-10. any info is greatly appreciated.
