If so, why do some people do it only for 1 week or 2 weeks? Pls clarify. November 8, 2017 at 10:19 am #18070 Alyssa VicensParticipant Well, it depends on individuals undergoing the HCG diet. Some may carry it for 3 weeks while others may do it for 1 or 2 weeks. However, it depends on the weight loss results the person obtains.
