J8o8h8n:
Between eating my entire 3000 calorie breakfast and about 2500 calories of what is supposed to be my 3500 calorie lunch, I'm feeling pretty tired. Is this a normal feeling when you push yourself past feeling full? Gonna see if I can finish the rest of the meal off later today and, if it's not too much, I might do another smallish (1000 calorie or so) McDonald's meal tonight too. I feel like stuffing with 7500 calories in a day is a good start to a potential gaining journey (or at least a test gain lol).
Also keep an eye out for sugar crashes:
The alleged mechanism for the feeling of a crash is correlated with an abnormally rapid rise in blood glucose after eating. This normally leads to insulin secretion (known as an insulin spike), which in turn initiates rapid glucose uptake by tissues, either storing it as glycogen or fat, or using it for energy production. The consequent fall in blood glucose is indicated as the reason for the "sugar crash".[4] Another cause might be hysteresis effect of insulin action, i.e., the effect of insulin is still prominent even if both plasma glucose and insulin levels were already low, causing a plasma glucose level eventually much lower than the baseline level.[5]
Sugar crashes are not to be confused with the after-effects of consuming large amounts of protein, which produces fatigue akin to a sugar crash, but are instead the result of the body prioritising the digestion of ingested food.[6]
