I recently quit drinking cokes and switched to diet coke. I gained 4 pounds. I switched back to regular cokes and lost the 4 pounds. So I know I need to quit the cokes... but I am not sure that alone will do the trick. I know I need to lose 20 more pounds. The problem is I already exercise almost every day. I go to the gym or I run or I do and hourly long hike at a high cadence that is has some very good hills. I sort of feel my body is too use to my exercise routine. Should I try fasting? A juice fast? Ten years ago or whenever had the thread here I had success with atkins. Should I do that again. In short what is the best way to lost 20 pounds and keep it off. if you feel like answering... thanks in advance.
