Hi Beck813
There is a cheaper alternative but you have to be very organised, regimented and count calories like there is no tomorrow.
Basically the diet works by your body going into ketosis and so burns the stored fat down quickly. This is interrupted when you introduce carbohydrates, as your body will always want to burn the carbs first. For your body to stay in ketosis you have to consume less than 20g of carbs per day. And for the calories to be pretty much equal to the Alizonne diet you only consume 550-600kcals per day spread across 5 small meals at 2-4 hour intervals) - it is extreme which is why it is great to have a Dr as part of the Alizonne plan. So you could do something similar to the atkins diet or the palaeo diet (minus the carb stuff) and switch to using full fat everything (sounds counter intuitive - but the replacement for the good fats are carbs - so low fat alternative are not always that good for you). However the problem with going it alone is that you wouldn't have access to the Dr, or either of the treatments - ultrasound to empty the fat cells or the LPG to tighten any loose skin.
However you can make it slightly cheaper for your self on the vitamin front. I have found the quinton solution you are meant to take twice a day horrible and i didn't notice it was doing anything for my hair and nails, so i started to take perfectil - much better alternative (asda have them on offer at the moment) the multivits, magnesium, potassium and calcium tablets are also cheaper either purchased online or at the supermarket. the only ones i buy at the Dr are the salt tablets - as i haven't found them anywhere else. You need to make sure that the mg of the tablets are the equivalent of those from the Dr though and they have all the right stuff in (multivits in particular).
All in all, if you want to loose weight and want the support network to help you through I could not recommend Alizonne highly enough. It has taught me how to eat properly and even highlighted food which i am allergic to. I am on phase three at the moment with only 400g left to loose to achieve my target weight. In total I have lost just over 2 stones since July 3rd and I have never been happier or healthier (I haven't taken my inhaler since starting Alizonne and I have (had :-)) bad asthma). If you are still unsure about giving it a go after reading all these motivational and inspirational messages, just go along to your closest Alizonne clinic for a free consultation and talk to the Dr.
Hope this helps :-)
