with atkins you are in ketosis but as previously said the calorie deficit is not as huge.. also I would think it unhealthy to try to stay in ketosis for long periods of time.. the body will fight as hard as it can to get out of it.. the atkins diet does work.. but at one point you will have to eat healthily ie; not removing a whole food type from your diet, such as carbs.. carbs are nessecary to function and without them long term you could have a number of health problems... a high protien diet is the way forward, high protien, low fat, high fibre, with slow release carbohydrates such as wholemeal rice/pasta/bread.... with the atkins you are consuming foods that will lift your choloestorol and cause fatty deposits in your organs.. the ideas you can eat copious amounts of steak bacon eggs etc. and loose weight is not sustainable.. you may well loose weight but you will not be healthy.. thats why on lipotrim small amounts of carbs are introduced as we need these carbs to function in the long term... you canget bowel problems, digestive disorders etc. if you remove any food group from your diet for long periods of time... and you dont want to be dieting forever, as it isnt healthy... hth x
