Kristen Saban, daughter of legendary football coach Nick Saban, has been in the spotlight recently, addressing both rumors about her father's potential return to coaching and, indirectly, the topic of weight management through discussions of metabolism and healthy living. This article explores Kristen Saban's recent social media activity and connects it to broader discussions about metabolism, weight loss, and the challenges of maintaining a healthy lifestyle, drawing on insights from evolutionary anthropology.
Setting the Record Straight: Nick Saban's Retirement
Following Nick Saban's retirement from coaching at Alabama after 17 seasons, rumors began circulating about a possible return to the sidelines. These rumors gained traction when former Tide QB Greg McElroy cited "someone who would know" as suggesting Saban might not stay retired. The speculation became a major topic at SEC Media Days, prompting responses from coaches and fans alike.
Kristen Saban took to social media to dispel these rumors. According to her, you can officially close the book on the potential for her Dad to return. He's thrown away his whistle and cast aside his straw hat. Kristen's statement aimed to put an end to the speculation and confirm that her father is indeed enjoying his retirement.
Life After Coaching: Nick Saban's New Chapter
Since retiring, Nick Saban has transitioned into new roles, including joining ESPN as a weekly analyst on College GameDay and providing insights during NFL Draft coverage. Despite the persistent "itch to coach," Saban seems to be embracing his new chapter, which includes spending time with his grandchildren and pursuing other interests.
Kristen Saban's Social Media Activity: A Glimpse into Personal Life
Kristen Saban's social media presence has also drawn attention for other reasons. Some observers have noted changes in her online profiles, such as reverting to her maiden name, Kristen Saban, from her married name, Kristen Saban-Setas. Additionally, some posts have been described as "mysterious," leading to speculation about her personal life.

Metabolism, Weight Loss, and the Realities of Exercise
While Kristen Saban's direct involvement in discussions about weight loss is not explicitly documented in the provided text, her public profile and the broader context of health and wellness make it relevant to explore the science behind weight management.
The Economics of Life: Understanding Metabolism
Evolutionary biologist Herman Pontzer, PhD, uses the metaphor of "the economics of life" to describe metabolism. He explains that energy intake must match energy expenditure to power the body's systems. Pontzer's research challenges traditional assumptions about weight loss and exercise.
The Body's Defense Against Weight Loss
Pontzer argues that the human body is evolved to defend against weight loss. For half a billion years of evolution in animals, losing weight's been a really bad sign. Your body is built to be really good about defending its body weight. It doesn't want to change weight very easily. According to Pontzer, if you're losing weight, your economics are not sustainable. Your body works really hard to never lose weight and, if you do lose it, to sort of get back to where you were before.
The Hadza Study: Challenging Exercise Assumptions
One of Pontzer's most notable studies involved the Hadza, a hunter-gatherer tribe in Tanzania. The Hadza are much more physically active than the typical American. Despite their high levels of physical activity, the Hadza don't burn any more calories than we do. This finding challenges the assumption that increased physical activity automatically leads to increased calorie expenditure.
Energy Compensation: Re-juggling the Energy Budget
Pontzer's research suggests that the Hadza and other really physically active populations spend a bit less on those other processes to sort of make room for the physical activity. The laws of physics remain intact, undefeated. It's just that the way that they're spending their energy is different on other tasks. This "energy compensation" may be one reason why exercise alone is not always an effective tool for weight loss.

The Limited Impact of Exercise on Weight Loss
If we're strictly looking at weight loss, then this is just more evidence-and it's not the only line of evidence-but it's just more evidence that exercise alone is a pretty poor tool for weight loss. According to Pontzer, the long-term expected weight loss from exercise alone is something like 2 kilograms. Right? Less than five pounds. While exercise is beneficial for overall health, it may not significantly impact weight loss without dietary changes.
The Role of Diet: Calories In vs. Calories Out
Weight gain or weight loss, again, it's about that energy budget. Calories in versus calories out. Weight gain, obesity, overweight, these issues that we struggle with in the US, it is about the energy coming in. It's about the energy in part of the equation, so it is about diet. Pontzer emphasizes that weight management primarily depends on managing calorie intake.
Are All Calories Created Equal?
Yes, they are. So, whether you get your calories from carbohydrates or from fats or even from proteins, although you get a few of them from proteins in a typical diet, they all will have the same effect on your weight in terms of the calories that you store in your body is weight. While calories are equal in terms of weight gain and weight maintenance, different foods have different effects on overall health.
The Myth of Carbohydrates as the "Bad Guy"
I think that's really been oversold. So, simple sugars, added sugars in our processed foods that we eat are one way that we end up eating more calories than we planned to or we can trick our brains a bit into over consuming because your brain is pretty good at matching energy intake and expenditure. So, all those extra empty sugar calories are one way that you can push it over the edge. While added sugars can contribute to overconsumption, carbohydrates are not inherently detrimental to weight management.
The Dangers of Starvation Diets
The easiest way to slow down your metabolism is to starve yourself. Right? And a lot of what people recommend in terms of diets is essentially that. Right? I mean, you cut half of your calories out of your normal daily intake, your body will sense that as starvation. And so, again, you are an evolved organism. We all are. And humans and other animals will slow their metabolisms down to sort of try to get through this starvation period. Crash diets and severe calorie restriction can slow down metabolism as the body tries to conserve energy.

Aging and Metabolism: Separating Myth from Reality
When you look at energy expenditure per day, calories burned per day, from your 20s into your 60s, it's really steady. The big thing is driving how many calories you burn is your body size, basically, and how much of that is lean mass. Once you control for body size and fat percentage, there's no difference in metabolism. Metabolism remains relatively stable from your 20s into your 60s.
