What?!
Obesity is not a normal consequence of aging. Gaining some weight, yes. But obesity is not normal at any point in life.
I stand by my statement. The prevalence and degree of obesity have increased to epidemic levels, but the basic progression of obesity itself is an ancient process. Although life expectancy was short, those who did live longer decades in the past were much more likely to become obese. And age is still a measurable factor in the incidence of it, as is married status and whether one has children.
At almost every place, in almost every culture, the progression of age has increased the
likelihood of prosperity via social status, agricultural prowess, or economic power. Such progression, combined with the slowed metabolism and the previous inability to consume as much due to harder work for younger adults, leads to a pattern of adults growing obese as their metabolism slows, but their access to better and more food increases. This is true in pre-industrial societies as well as post-industrial societies.
Obese is defined as a BMI of 30 or above. A BMI of 30 roughly equates to 30 pounds overweight. Average weight gain during adulthood isn't unusual to be between 1-2 pounds per year. That doesn't mean everyone does, but it is a common enough pattern, and certainly preceded the modern problem.
Health consciousness and fat fighting diets and exercise regimens are relatively recent trends in the world for most cultures.

Sure, but both contain lactose right?
Could a lactose intolerant person drink human milk?
My understanding is that because, theoretically, we don't need lactase after infancy the body stops producing it. Ordinarily we'd stop consuming food sources with lactose in it so it wouldn't be problem. But because we consume other animal's milk we become aware of the lack of lactase in our digestive system because our bodies react so poorly to the unprocessed lactose.
Lactose intolerant people can drink any type of milk, but they will experience the same reaction because lactose is a type of sugar, just like sucrose, or any other sugar molecule.
A lactose molecule is particularly large, and the problem is that without the lactase enzyme, that sugar molecule arrives in the lower gut undigested and therefore unabsorbed. The flora in the lower gut then do the job that the upper GI tract failed to do, and the bacteria go to town on the sugar that they can and do break down. When they flourish and overpopulate, their byproduct is gas which results in the flatulence and diarrhea and cramping.
Human milk may have other virtues, but it has no more ability to be fully digested than cow's milk.
