To be fair, we don’t need infinite years/generations to select for favorable traits. Such a selection process might already be underway - obesity lowers fertility, so there is pressure towards not being obese. IMO the next generation will already be either slightly reducing their intake, or increase their expenditure of calories. There‘s many ways to do that - becoming taller, more restless, less hungry, decreasing intestinal uptake, reduced enjoyment of food (loss of taste/smell) etc
