Phase And Vertical Shift. Phase and vertical shift refer to the transfer of a function in the horizontal and vertical directions, respectively. For the function , where A, B, C, and D are constants, the phase shift is defined as C/B. If the phase shift is positive, the shift occurs to the left; if the phase shift is negative, the shift occurs to the right.
So it is possible that a whole food meal will have a different impact on the duration of protein synthesis than pure amino acids. Our lab has recently shown that the duration of protein synthesis in response to a complete meal containing protein, carbohydrates, and fats is approximately 3 hours long. Therefore, it appears that a complete meal slightly prolongs the duration of protein synthesis.
It takes only seconds for physical food to reach the physical stomach. However, the feeling of fullness is not determined by the filling of the stomach, but by an increase in blood sugar, which tells the brain you no longer need food. 20 minutes is the average time that this takes for a meal that includes some fat, some carbs and some proteins. If it is a protein only meal or one that is high in fat, it can take 40 minutes to an hour because the stomach must first digest the proteins into useable carbs before sending them to the bloodstream. Only then does the blood sugar rise and signal full to the brain.
