The Logi method
The Logi method is a low carbohydrate diet reduced form , which is based on nutritional recommendations for overweight children and adolescents obesity clinic at Harvard University Children's Hospital . You should have a healthy diet that allows to starve a weight reduction without . Logi stood there for the abbreviation for LowGlycemic Index (English: low glycemic index). In Germany, it was adapted by the German nutritionist Nicolai Worm and published in late 2003 in book form. It imitates the proposals of David Ludwig (Director Obesity Program , Harvard University Children's Hospital ) under Evidence points of view. Since the Glycemic Index to Worms believes " only half the truth " is , it defines logistics as "Low Glycemic and insulinemic ", ie with low blood sugar and insulin levels . Worm will not be understood as a diet, but as a permanent diet , the Logi method.
The Logi - pyramid
In principle, the user of the Logi method allowed to eat anything. It should be based on the food selection at the 4-level Logi pyramid that illustrates graphically in the style of the usual diet pyramids , the weighting of the recommended food choices . Free or low- intensity strength fruit and vegetables and healthy oils form the basis of nutrition dar. From salads and vegetables , the user must eat plenty .
The focus should be on the starch and low-sugar , high fiber and water-rich representatives from this food group . Because of their high weight and volume they are best saturate , and because their glycemic index is also extremely low, they are intended to influence the metabolism in an ideal way , so Worm . Fruit may also be eaten . However, the sweeter the fruit , the greater the amounts of sugar and carbohydrates , it can contain and result in a relatively high glycemic load , so here restraint is displayed. For the vegetable and fruit consumption also applies to the logistics method, the well-known " Five a day " recommendation , ie five times a day fruit and vegetables should be consumed , three servings of vegetables and two servings of fruit . Which lies in the conventional food pyramid at the top oils also shift to the base . Preference will be given olive oil and oils with relatively high content of omega-3 fatty acids, ie rapeseed oil, walnut oil and linseed oil.
On the second level of the pyramid sources of protein such as lean meat, poultry and richer or leaner fish and dairy products, eggs, nuts and legumes are to be found. From these foods something should be built into every meal .
On the penultimate stage of the pyramid are the whole grains and brown rice and pasta. That is, they do not have to be completely removed from the diet , but should be eaten in limited quantities. The reason: They have a medium GI , but produce at the usual serving size because of their high carbohydrate content , a relatively high glycemic load . This position is in stark contrast to the current semi - official food pyramids , such as the German Society for Nutrition ( version 2005 ) , in which these carbohydrate carrier are at the base.
At the top of the pyramid grain products are made from refined flour ( white flour) , positioned floury potatoes and sweets, this should rarely or never consumed.
Basis of the Logi - pyramid is the Glycemic Load
Blood sugar levels should be kept by carbohydrate restriction at a constant low level to allow improved saturation effect and fat burning
Intended to achieve this , the energy needed to get about 45 percent from fat and 25 percent from protein-rich food
The increased intake of vegetables, salad, fruit , berries, mushrooms, legumes , etc. leads to a high fiber and water intake at low energy density.
The increased protein intake should be calorically advantageous addition to the long -lasting satiation in the course of specific dynamic action in digestion.
Thanks to an excess of base , there was no acidification risk
In principle, the logistics method is suitable according to Worm for all people. Benefited the most obese individuals with elevated blood fat and blood sugar levels, and especially those suffering from the metabolic syndrome, but also patients with type 2 diabetes (diabetes mellitus) .
After Worm applies: In the method of the blood sugar level remains constant during a diet that does not consider the glycemic load . Larger fluctuations in blood sugar and / or blood sugar spikes can be prevented so that the insulin level is always kept relatively low during the day. That brings health benefits : For example, this blood fat levels are lowered and prevented the formation of fat deposits. Also gout patients have advantages, since the uric acid values are expected to fall despite higher meat consumption . An exception is patients whose uric acid levels due to a kidney disease whose renal function is too high and restricted.
Studies on the effectiveness
In a study published in January 2006 study reports on the positive experience of type II diabetic patients in the rehab clinic Überruh three weeks after LOGI Kost (20-30 % carbohydrates, 20-30 % protein, 40-50 % fat ) have nourished. In addition to weight loss , a significant improvement was observed in the metabolic variables. In addition , more than half of patients stop taking drugs ( oral agents and insulin) and in the other a reduction of about half of it was possible. Meanwhile, three other clinical studies from Germany have verified the effectiveness of the LOGI method.
The 2010 published European Diogenes study, involving 772 families have participated with 938 overweight adults and 827 children , supports the theory of Logi method by showing that a protein-rich diet with kohlenhydratreduziertem proportion preventing overweight or facilitates the removal can be prevented the yo- yo effect and most easily implemented in everyday life permanently. The Study Group on a diet with a higher protein content (25 percent protein content) and low glycemic index had by all five study groups the best results.
Another 2010 published study supports the hypothesis that a low-fat , calorie -reduced diet with a high protein content (33%) compared to a diet with a normal protein content (19%) over a period of 16 weeks leads to the fact that body weight, body fat mass and best to reduce waist circumference with the reduced calorie high protein diet in conjunction with a strength training.
Contrast to similar diets
The Logi method is similar to the Montignac method and the low GI diet. However, in the Logi - less method of GI ( glycemic index) and more the GL ( glycemic load ) for the selection of food is used , which distinguishes them from those listed .
Logi can be classified as so-called low -carb diet. Unlike the Atkins diet but foods with carbohydrates in a much greater degree are allowed.
Logi is a further development of diet suggestions from David Ludwig of the Medical School of Harvard University . Nicolai Worm has its Logi - pyramid modified by mutual agreement.
The importance of the glycemic index or glycemic load is provided by some nutritionists in question , in Germany by the German Society for Nutrition, which represents a carbohydrate -heavy diet. For example, even the German Institute of Human Nutrition questioned in an opinion from the year 2004 to the importance of the glycemic index on the body weight gain .
For this diet similar criticism made of low-carb apply .
For people with impaired renal function -protein diets are recommended only with caution and under medical supervision .

Die Daten zum Einfluss des glykämischen Index auf die Körpergewichtsentwicklung sind nach wie vor inkonsistent und auch umstritten; es ist noch nicht gezeigt, dass eine Verringerung der glykämischen Last (durch Modifikation oder Reduktion des Kohlenhydratanteils der Diät) anderen diätetischen Interventionen (z.B. Reduktion des Fettanteils) eindeutig und nachhaltig überlegen ist.“
