A small Swedish study suggests that a 5 weeks diet Paleo is enough to relieve the burden of liver fat, while losing weight and improving many health parameters.
The accumulation of fat in the liver (steatosis), but also in the muscles is a very common phenomenon in modern society. It increases with age, and promotes insulin resistance, diabetes and of course overweight.
But this is not inevitable. It is known that these are diets high in carbohydrates (bread, pasta, potatoes, pizza, sweet products, etc …), low in fiber, which, combined with a sedentary lifestyle, are at the origin.
Hence the idea of Swedish researchers to explore the effects of a Paleo-type diet of these adverse events. The Paleo diet theory excludes food from agriculture, introduced in Neolithic cereals, dairy products, salt, sugar, pulses, oils.
For this study, 10 healthy postmenopausal women with an index greater than 27 body mass were instructed to follow a modified Paleo diet without calorie restriction. This system, less strict than the Paleo reference model, brought about 30% of calories as protein, 40% as fat (mostly monounsaturated as found in olive oil, avocado ) and 30% in the form of carbohydrates.
Results: While the women could eat at will, depending on their hunger, they actually reduced their calorie intake by 25%.
The average weight loss was 4.5 kg. The body mass index, waist circumference, waist hip, waist / hip ratio, the sagittal abdominal diameter (between spine and tip of the abdomen) were significantly reduced. It was the same in blood pressure, total cholesterol, triglycerides, LDL-cholestérol/HDL-cholestérol ratio, apolipoprotein B (ApoB) and apolipoprotein A1 (ApoA1), urinary C-peptide ( a marker of insulin secretion) and HOMA index (marker of peripheral insulin resistance). The insulin sensitivity of whole body (which combines hepatic and peripheral sensitivity) has not changed.
The fat content of the liver decreased by almost half (49%). The fat content of muscle cells did not change significantly.
