Researchers decided to do an experiment in which 4 men and an equal number of women, average age 29, exchanged their standard diet for a low-carb high protein diet for a week. The figures: the subjects’ diet before starting consisted of 60 percent carbs, 30 percent fat and 10 percent protein [Before diet]. They replaced this with a diet consisting of 35 percent protein, 60 percent fat and only 5 percent carbohydrates.
The insulin level peaked after the 3 main meals in the ‘Before diet’, but that on the low-carb protein diet the peaks have almost disappeared.
You’d expect muscle mass to decline, but this didn’t happen. The researchers extracted cells from the vastus lateralis leg muscle and recorded the muscle tissue growth. This actually increased after the subjects went over to the low-carb diet.
The protein diet had increased the activity of anabolic signal molecules in the muscle cells. The most noticeable effect was that the muscle cells started to produce more IGF-1. This is different IGF-1 to that found in the bloodstream.
"Increasing dietary protein content during a carbohydrate restricted diet may be important for preventing or attenuating a net loss of body protein", the researchers conclude.
