Many of us have tried, at one point or the other, a particular diet or exercise plan (if not several) that promised us the body that we desire. But what if someone were to tell you that maybe weight-loss is not as simple as that? At least not anymore.

Researchers have discovered that weight control may not be as simple for our generation as it used to be in the olden days.

According to Daily Mail, studies claim that teenagers simply do need to eat lesser and exercise more than their parents did to get the exact same results. So pay attention.

Diet comparisons across generations revealed that people who consumed the same number of calories were still 10 per cent heavier in 2008 than they were in 1971.

What's more, people who underwent the same amount of physical activity in 2006 were 5 per cent heavier than in 1988.

A thorough analysis of the diets of 36,400 people and exercise and lifestyles of 14,419 people across different periods, has placed a pretty solid question mark on the world's long-held beliefs about weight management.

Turns out maintaining a healthy Body Mass Index (BMI) is in fact not solely about controlled eating and more exercise.

Not only do these results explain the consistent rise of obesity, but they may also indicate that there are several other factors at play in the processes of weight-loss in the evolved human body.

These factors include but aren't limited to medication use, environmental pollutants, genetics, timing of food intake, stress, gut bacteria and even night-time light exposure. These elements of our lifestyle heavily affect the complex processes that the human body undergoes when attempting to shed mass.

And diet and exercise can really only do so much.
