Let this sink in. The obesity crisis since 1976 has occurred even though we ate about 450 calories MORE in 1976 than now. That is, we’ve cut calories by 450/day and increased obesity.

So here’s the first big surprise: we ate more in 1976. According to government figures, we currently consume an average of 2,130 kilocalories a day, a figure that appears to include sweets and alcohol. But in 1976, we consumed 2,280 kcal excluding alcohol and sweets, or 2,590 kcal when they’re included. I have found no reason to disbelieve the figures.
“Today, we buy half as much fresh milk per person, but five times more yoghurt, three times more ice cream and – wait for it – 39 times as many dairy desserts. We buy half as many eggs as in 1976, but a third more breakfast cereals and twice the cereal snacks; half the total potatoes, but three times the crisps. While our direct purchases of sugar have sharply declined, the sugar we consume in drinks and confectionery is likely to have rocketed (there are purchase numbers only from 1992, at which point they were rising rapidly.”
Further reading brings clarity.
More Kcals were consumed because the sources were higher protein and fat, which have a higher calorie density while having a lower glycemic impact. Less glucose = less insulin = less obesity.

It’s all tied to insulin, and the thing that has the biggest impact on insulin is stress (cortisol). The biggest impact on cortisol comes from sleep or lack thereof.
So of course between 1976 until now people have endured more and more stress. Also what has a big impact on stress is diet (obviously), and a diet that facilitates proper hormone function (meat and eggs) will help with stress.
