Slim Diet 2 is also marketed as UDII and SDII

Using ketosis for weight loss has several advantages :

Rapid weight loss - 250g - 500g per day minimum (more in first week) which is comparable to that achieved during complete fasting.

Increased energy - Burning off 500g of fat will produce 3,600 calories of energy.

Increased mental capacity - Ketones when used as a fuel for the brain, can increase concentration and memory capacity.

Fluid balance - Ordinary low-calorie diets do not have the capacity to reduce fluid retention, particularly with very obese people. A Protein-Sparing Modified Fast diet balances body fluids.

From Day 2 of starting the Slim Diet, the urine should be checked with the Uriscan. The reading should be on pink (minor or small) for best results. This should be achieved within 48 hours. The urine should be checked first thing in the morning. Check the urine before the evening meal as well for the first week. If the Ketone reading is too high (large or major), then you are either not drinking enough water or need to increase carbohydrate intake. If the Ketone-reading is too low (nil) then you are having too much carbohydrate. If you are higher up on the scale, your body can tolerate a little more carbohydrate. Increase your intake slowly, testing your urine every day, until you find your personal Critical Carbohydrate Level (C.C.L.). For the first few days of the diet, keep your carbohydrate intake to a minimum so you will get into ketosis quickly. Once the body has been in ketosis for a week, you can afford to experiment and find your own critical carbohydrate level (C.C.L.).
