For starters, let's see, whereby degreasing products?

Usually animal fats in milk, yogurt, mayonnaise substitute for soy are soy protein isolate and soy flour. While the nutritional composition of product modified proteins becomes more and lipid-soluble acids less. Decreases the amount of cholesterol and saturated fatty acids. As due to reduction fat is suffering the consistency of the product composition appears additives: a variety of stabilizers and thickeners. Often they have no energy value and can be very useful for our organism, such as algae. But the course is and starch, which cannot be called useful (especially genetically modified), even though the calories and half the fat.

Often animal fat replaced by vegetable: the most common case is a "light" mayonnaise. Moreover, the TRANS fats they contain (as in kachestvennyh spreads), but there are useful polyunsaturated fatty acids.

All the attention - on the label!

If you are aiming to lose weight, amount of fat really need to limit (but within reason). Give preference to low fat products. Judge for yourself: let's say you drink 3 cups of milk a day. With fat content 3.5% is 22 (!) g of fat and if fat 0,5% - only 3 grams! Moreover, scientists have proved that the skim milk retained almost all the nutrients. Of course, a certain amount of vitamins will is lost, but the producers care about it enriching your product by them additionally. Evidence that they are digested worse, no. What is not true about calcium... unfortunately, calcium from the milk fat content of below 1.5% digested worse, so it is best to alternate products with low and optimal maintenance of fat.

And carefully read the labels! Very often low fat foods contain an excess of starches and sugars. It can also happen that the manufacturer specifies the wrong fat product, so trust only proven brands and farms. And remember an emotional moment: often people can sort out of calories for the reason that, say, "this is a diet product, and therefore you can eat a lot!".

How to get the best results from a diet low in fat?

In a diet low in fat decreases the level of "bad" cholesterol and increases level of "good". This reduces the risk of atherosclerosis. But it is important not only to reduce the fat content, but also to give preference to vegetable fats (oils) and cod-liver oil. It is these types of fats should be 25% of the daily energy needs! The lack of fat leads, paradoxically, to increase the level of "bad" cholesterol and triglycerides in plasma. Reduced tolerance to glucose. In addition, people instinctively becomes prone to overeating carbohydrates.

Take a sample of Scandinavian diet (and the variant Mediterranean), and also do not forget that without the active sports case will not succeed!
