Get Fit at Any Age

Whereas my previous blog outlined ten general principles for healthy living, this article provides a comprehensive overview of the diet plans and workout routines I have used to stay in great shape at 40 years old.

Please understand that this article is long - twice as long as most pieces I have written. However, I am so convinced of the positive correlation between physical fitness and professional success that I felt compelled to empty my entire playbook.

“But what do you know?” you might be thinking. “You’re not a trained professional!”

You’re right. I’m not a trained professional. Nor do I claim to have everything figured out.

However, I have spent the better part of two decades reading, writing, listening, and learning about fitness. I enjoy experimenting with new ideas, tracking how my body responds, and adjusting for optimal performance.

Whereas I may not have the “personal trainer” title, very few people have given physical fitness as much attention as myself.

Given my profession, I decided a shirtless pic would not be wise.


Getting ripped begins - and ends - with a healthy diet. No matter how hard you work out, if your intensity toward dieting does not match your intensity toward exercise, it is impossible to get shredded.

"Dieting is so overwhelming," you may be thinking. "I don't even know where to start!"

I don't blame you.

Every time we look, a new fad diet is sweeping the country. Atkins, South Beach, Vegan, Keto, Paleo … there are too many to choose from! And now with Instagram "models" and TikTok "influencers" constantly shoving diet ideas down our throats, it's impossible to know who to believe.

Do not get suckered into buying these products and plans. Instead, understand that weight loss is simply calories consumed versus calories burned. In fact, every weight-loss study conducted over the past century has concluded if you consistently consume fewer calories than you burn, you’ll lose weight.

Consuming fewer calories than are burned is commonly referred to as a calorie deficit diet. The first step in a calorie deficit diet is determining your daily calorie target - the number of calories you must stay under to lose weight. While there are several methods for calculating your daily calorie target, the most accurate is the Harris-Benedict Formula.

Several online calculators for the Harris-Benedict Formula exist. My current favorite can be found at When using this calculator, you will be asked to enter your age, gender, height, weight, and activity level. Below were my numbers at 40 years old:

I want to highlight two things about this table: the Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE).

BMR is the number of calories naturally burned each day based on age, gender, height, and weight. My BMR is 1,869 ... meaning if I never left the house and lived a sedentary lifestyle, I would need to consume less than 1,869 calories per day to lose weight. While this number is realistic, I would not recommend a life of inactivity (more on this later).

TDEE is the number of calories naturally burned (BMR) plus the calories that are burned as a result of physical activity throughout the day. My TDEE is 3,225 calories, meaning I can consume nearly 1,400 more calories per day and still maintain or lose weight thanks to having an active lifestyle.

When using the Harris-Benedict Formula, keep in mind the following:

Eat less calories than your TDEE = lose weight

Eat the same calories as your TDEE = maintain weight

Eat more calories than your TDEE = gain weight

One important rule of thumb to know is there are roughly 3,500 calories in a pound of fat. This means if you cut 3,500 calories from your diet (or burn 3,500 calories through exercise), you can expect to lose a pound of fat.

For example, say your TDEE is 3,000 calories and you only eat 2,000 calories a day. Given our rule (3,500 calories = 1 pound of fat), how much weight can you expect to lose in a week?

3,000 TDEE – 2,000 calories consumed = 1,000 daily calorie deficit

1,000 daily calorie deficit x 7 days = 7,000 calories “under” TDEE

7,000 calories / 3,500 (one pound of fat) = 2 pounds burned in one week

Once a daily calorie target has been determined, you must develop a system for tracking the number of calories consumed throughout the day.

“But Jared, isn’t calorie counting bad?"

I get it. The words “calorie deficit” and “calorie counting” have endured plenty of criticism, especially as the number of mental health issues related to dieting continues to climb. However, most people have no idea how many calories they consume during the day. In fact, most adults dramatically underestimate their calorie intake – often by as much as 2,000 calories per day.

So, how does one calorie count? One of the best places to start is the MyFitnessPal app. MyFitnessPal has a massive database containing the calorie and nutrient data for thousands of foods. Whenever you consume any food or drink, simply enter your items and the app does the math for you.

At first, I didn’t think I needed to count calories. "This is a waste of time," I thought as I reluctantly tracked calories using MyFitnessPal for the first time. However – at the end of the first day – I couldn’t believe my eyes. I had consumed well over 4,000 calories! No wonder I wasn’t losing weight.

From that that day forward, I used the MyFitnessPal app to track every meal, snack, drink, and dessert for several months. At first, it was hard to take 1,000-plus calories out of my daily diet. "What do you mean I can't have a bowl of ice cream after dinner?" I pouted. However - over time - my appetite got used to the new normal.

After several months of tracking hundreds of meals and individual food items, I no longer needed the MyFitnessPal app because I had memorized the calories for the handful of foods I ate regularly. And for the foods I didn't eat regularly, I developed a ballpark idea of their calorie amounts.

This brings me to a key idea for this chapter: having a general understanding of the calorie counts for most common foods is a valuable skill to learn. Those who follow a calorie deficit diet don’t always have the time to track calories. Therefore, it is important to learn how to do quick mental math to ensure your daily calorie target is not exceeded.


One common calorie-counting question has to do with food quality: Does nutrition matter? Or, is it all about the calories?

Mixed opinions exist on this topic. Some people maintain that calories are all that matter. This means you could eat 13 S’mores Pop Tarts (2,405 calories) or 4 Big Macs and a medium Coke (2,462 calories) and still lose weight assuming the daily calorie target is preserved.

While I haven’t tried living off of Pop Tarts or Big Macs, I have read enough to know that people who want optimal results should eat a well-balanced diet full of foods that are rich in vitamins, minerals, and other nutrients.

This is where a personal rule of thumb comes into play called The 80% rule.

The 80% rule suggests people who are serious about weight control should eat “clean” foods 80% of the time. Eating clean means choosing foods that are close to their natural state and not overly processed. Clean foods are typically found around the perimeter of a grocery store and include fresh fruits, vegetables, lean meats, whole grains, and dairy products.

For the other 20% of the time, people are allowed to eat “non-clean” food. Non-clean foods are typically found in the center of the grocery store and include heavily processed and pre-packaged foods such as chips, cookies, cereals, breads, frozen dinners, soda, and alcohol.

In a moment I will propose that unhealthy eating is limited to one “cheat” day per week. People who follow this model eat clean six out of seven days a week – or 86% of the time. No matter if you use the “cheat day” approach or a different system, eating clean 80% of the time is a great rule of thumb to follow.


Are you ready for a sample meal plan?

Recall my numbers from earlier in the chapter: 40 years old, male, 75 inches tall, 180 pounds and a TDEE of roughly 3,200 calories per day. Given that I am still trying to lose that last bit of fat - plus I have a built-in cheat day (more on this later) - my current daily calorie target is 2,500 calories.

The following is the meal plan I have used for the last couple years. I usually follow this meal plan Monday through Friday, with a “Cheat Day” on Saturday, and a slightly modified - yet healthy - day on Sunday.

This diet plan often raises questions. Here are a few of the most common:

“You eat the same meals Monday through Friday? That is way too scripted for me!”

I realize that most people do not want to eat the same foods every day. However, consider the foods you currently eat on a daily basis. I’m willing to bet you eat a lot of the same foods regularly - especially for breakfast and lunch. Fact is, most people tend to rotate through a number of “staple” meals throughout the week. Once you find meals that are tasty and healthy, I would suggest that you rotate through those meals for the sake of convenience and to prevent overeating.

“My spouse will never go for this!”

I agree, most spouses will not appreciate the rigidity of this plan. When I was married, my wife loved to cook for us. Of course, I knew better than to turn down her homemade meals! To compromise, I would eat my “typical” breakfast (500 calories) and lunch (700 calories), but then at dinner I would eat whatever my wife had made. Knowing that I had roughly 1,000 calories to play with gave me plenty of options, yet helped prevent overeating (and resist dessert!).

“Wait, you make omelets for lunch? Aren’t you supposed to be at work?”

When I moved into my first superintendent role, I bought a house within walking distance of my office. While initially hesitant about the location, I loved being so close because I could go home for lunch. I’ll be honest … my head is spinning by the time the noon hour rolls around. Rather than continue to scramble my mind by eating lunch at my desk, I run home to decompress and eat a healthy meal. Any time lost by taking a lunch break is more than made up for thanks to increased afternoon productivity. School leaders wanting to perform at the highest levels would be wise to schedule daily mental health breaks.

“How did you choose those foods?”

I have spent years researching the best foods to eat. Depending on the study, you can make a case that any food is good for you (“Drink red wine and eat dark chocolate and you’ll live to be 110!”). Most foods on my meal plan are selected not only because I like the taste, but also because they are proven to burn fat.

Consider the following:

Why Almonds? While nuts contain more calories per gram than most foods, they are natural dietary fats that also boost metabolism. Studies indicate that participants who eat almonds with meals lose more body fat and more stomach fat compared to groups who don't eat almonds.

Why Blueberries? Blueberries have been shown to speed up the fat burning process and are protective against weight gain. Furthermore, eating three servings of blueberries per week has proven to reduce heart attacks by as much as 34%.

Why Eggs? Few foods contain proper nutrients while also managing hunger like eggs. Regardless of how you like yours cooked (I’ll take mine over hard, please), eggs have been proven to speed up fat loss and reduce food cravings throughout the day.

Why Mushrooms? Mushrooms are an excellent source of fiber, which enhances weight loss. Other nutrients like potassium, copper, and B vitamins support cognitive functioning. Adding two to four servings of mushrooms per week helps improve memory and reduce cognitive impairment by nearly 50%.

Why Spinach? Just like Popeye the Sailor Man, humans gain incredible powers from this low-calorie, leafy vegetable loaded with nutrients. Not only is spinach great for weight loss, this superfood also strengthens bones, improves eyesight, and improves skin quality.

Why Water? Drinking large amounts of water increases metabolism and triggers the release of stored body fat. Drinking 20 ounces of water within a couple minutes temporarily boosts metabolism rates by 30% and burns around 25 calories. While 25 calories may not seem significant - when done three times a day over the course of a year – 27,000 calories (more than seven pounds of fat) are burned.

“I'm strong to the finish 'cause I eats me spinach.”


“Ok, so tell me about your cheat days."

Before we discuss my cheat day, let’s be clear that eating disorders are nothing to mess with. Many people who participate in strict diets have problems with bulimia and anorexia. If you experience mental health issues related to dieting, please contact a health professional.

To combat potential mental health issues, it is important to build in diet breaks. A cheat day is when you have one opportunity each week to splurge on all your favorite foods. By giving yourself permission to eat pizza, French fries, donuts, cookies, ice cream, and all of your guilty pleasures, bottled-up cravings are removed from your system so you can focus on eating healthy for the remainder of the week.

Psychologists and nutritionists agree that cheat meals allow individuals to eat better throughout the week. This planned calorie splurge allows people to forgo other unplanned and binge-inducing meals – meals that take much longer to recover from and could throw you off the wagon altogether. Furthermore, research shows cheat meals increase metabolism, causing you to burn calories faster.

“But I gain five pounds on cheat days! Aren't I ruining my diet?”
