I will be very honest: I have mixed feelings about this product. After going through all the reviews here on walmart.com, I decided to give this a go. I ordered, it got to me quickly, everything seemed good and I started off optimistic. Of course the 2 loading days were the best whereby you go along with your day worry free eating til your heart's content. My starting weight was 185. After the 2 loading days, I ballooned up to 189. Starting the 500 calorie diet, I made sure to space out my options during the day to leave no room for hunger. eg. Breakfast (9 am): Green tea and an apple, Lunch (12:30 pm): Spinach and turkey, Mid-afternoon snack (3:30 pm): 5 strawberries Dinner (7:00 pm) : Green salad and grilled chicken. (I try not to eat after 8 pm even when I am not on any diet) I kept only to the allowed options on the food list, using seasoning and herbs with juice from lemons as replacement salad dressing. I also drank 2.5 liters of water a day and tried to switch up the options on the list to not hit a stall. All was going well for about 8 days... in those 8 days I went from 189 to 175. This is because the first day I lost 4.5 lbs and went from 189 to 184.5 lbs to almost my original weight and after a good bathroom session (TMI I know but I said I would be honest). Over the next 7 days I proceeded to lose 9.5 lbs and was happy. I took measurements of my waist, hips, etc and they seemed to have gone down a bit so I was happy to be on my way to weight loss! That's until day 9, when my niece gave me a chicken nugget. I said no at first but temptation got the best of me and I ate it. BUT(!!) not without peeling off the fried part first, no dressing, no dipping sauce, nothing, only the chicken. On day 10, I do my standard routine whereby I weigh myself in the morning before I start my day, You will NOT believe it, I weighed 183. On day 10, after following this diet to protocol, except for that one piece of chicken nugget, my weight went from 175 to 183 OVERNIGHT! That was very discouraging. 8 lbs difference over a chicken nugget? I even went to step on my roommates scale and it said the same! I immediately called the hotline and they said that I need to follow EXACT protocol and make sure I am drinking enough water and perhaps don't eat the same food everyday to not have a stall...all things I was doing already (after proper research) but yet I somehow managed to go from 189 to 175 in 8 days but overnight I gained 8 of it back by half ounce of chicken. OBSURD. So the hotline attendant said to have an apple day, which I did on day 11. On day 12, I weighed 182.5. I continued for a couple more days and on day 15, I weighed 179. Diet had totally changed and slowed down. That's why I say I have mixed views about this. I changed nothing for 15 days except that one error, which seemed to throw everything off. Makes me even wonder if this really work or it was just my body in shock by only eating 500 calories a day. Needless to say, I came off it because I don't feel like its the right diet for me. All this anxiety of if as much as smell 'bad' food might make me change weight is not for me. Kudos to you guys who saw amazing results on this and extra kudos to those who even said they cheated and still lost weight. Also be careful because this product stays in your system long after you're off it. Hope this helps to someone who might want an unbiased review... Also, I'm 29 if you wanted to make an age relation.
