Atkins Frozen Meals are designed for the requirements of the Atkins Diet which limits net carbohydrates. When dieters eat less than 50 net carbohydrates as is recommended, it has a diuretic effect on the kidneys and speeds up the amount of salt and water your kidneys get rid of. We recommend supplementing with additional sodium in the early stages of the diet to make up for this diuretic effect on your kidneys. There is a range of sodium values in our meals. If you have specific health related issues, we recommend consulting with your physician about whether or not our Frozen Meals are appropriate for you.
