Navigating the world of diets can feel like a constant battle. Not too long ago, the Paleo diet seemed like just another fleeting trend, quickly dismissed as a fad. But then, fitness trends like CrossFit surged in popularity, and suddenly Paleo became a mainstream topic, even sparking debate in publications like the New Yorker. It dominated Google searches in 2013, proving its staying power in the ever-evolving landscape of food and nutrition.
About six years prior to this surge, I embarked on my own personal “Man Vs Food Food” experiment, a deep dive into the chaotic world of dieting. As a content creator for foods.edu.vn and a self-proclaimed food expert, I felt compelled to explore the maze of nutritional advice firsthand. I dedicated a year to rigorously testing six distinct dietary plans, spending two months on each. This wasn’t about weight loss; I was already lean from competitive cycling. My goal was far more ambitious: to uncover a healthier, sustainable way of eating that I could genuinely embrace long-term.
My journey wasn’t without its deviations. I allowed for occasional cheats, understanding that real-life eating isn’t always perfectly regimented. My detailed experiment, initially documented for Outside magazine, sought to cut through the noise and identify practical, lasting dietary habits. Much has transpired since that original exploration. Life changes – career shifts from Outside to Wired and back, personal transitions like divorce and remarriage, geographical moves from Santa Fe to Boulder to San Francisco and back to Boulder – have all occurred. Yet, throughout these changes, my weight has remained remarkably stable, fluctuating only slightly between 154 and 160 pounds. My doctor even lauded my blood work in a recent physical as “suitable for framing,” a testament to the enduring impact of the dietary principles I discovered.
My current eating habits largely mirror the Mediterranean diet, refined and personalized through the rigorous experimentation I detail below. My daily routine typically includes kale and berry smoothies for breakfast, sometimes swapped for spinach omelets with olive oil-dipped bread. Lunches are often veggie and turkey wraps or vibrant salads. Dinners lean towards pastas, salads, and fish. I’ve eliminated dairy and nightshades, minimize red meat to grass-fed or game options, and incorporate plenty of almonds, almond butter, and liberal amounts of olive oil. Crucially, I allow myself a “free” day every week or ten days, eating whatever I crave.
So, revisiting my findings from six years ago, which remain surprisingly relevant today, I present my dietary journey and the insights that shaped my enduring approach to eating.
The “Thin Equals Healthy” Myth: Challenging Food Assumptions
“But you’re so thin.” This was a common refrain when I announced my year-long diet experiment. It was August 2008, the tail end of a demanding cycling season. At 5’11” and 149 pounds, I was undeniably lean, bordering on scrawny. These comments, often laced with Olsen-twin jokes, highlighted a pervasive assumption: people only change their diets when they need to lose weight.
The flawed logic is that thinness equates to health. If you’re slim, your diet must be inherently “good.” This couldn’t be further from the truth. Thinness, especially in athletes, doesn’t automatically guarantee health. Many of us use our athletic achievements, like fast 10K times, to justify poor food choices. I recall Robin Williams, a known cycling enthusiast, humorously responding to an interviewer’s question about weight management: “I can eat pretty much anything. I ride bikes.” This attitude is widespread; sometimes, the allure of a long workout is precisely the promise of post-exercise indulgence in beer and burgers. A government survey even indicated that heavy drinkers tend to exercise more than abstainers, perhaps reflecting this compensatory behavior.
At 38, with a family history of heart disease and a personal history of late-night pizza cravings and inconsistent energy levels, I recognized the need for a better approach. I sought a dietary strategy that fostered healthier eating habits without demanding rigid adherence to overly restrictive or dogmatic programs. However, the diet industry largely catered to overweight individuals, for whom even basic exercise would be considered an improvement. Options for already trim, year-round athletes were scarce.
This gap in the market spurred me to undertake a radical experiment. I resolved to spend eight weeks on each of six distinct diets, representing a spectrum of popular and scientifically-backed nutritional approaches: the Abs Diet, the Paleo Diet for Athletes, the Mediterranean Prescription, the Okinawa Program, a personalized plan from a nutritionist, and the USDA’s nutritional pyramid. I meticulously tracked every meal, snack, caloric beverage, and workout, alongside detailed notes on my physical and mental state. Bi-monthly visits to my doctor and the lab provided data points – weight, cholesterol levels, and body composition analysis. I allowed for only two breaks: 19 days for my honeymoon post-Abs Diet, and 11 days around Christmas and New Year’s following the Paleo Diet for Athletes. It was, undeniably, a huge undertaking.
My hypothesis was clear: by applying the same discipline to nutrition that I applied to cycling, I could objectively evaluate these diets against their purported claims. I anticipated that each diet would offer valuable lessons, and equally, that each would likely fall short in some aspect. Through this rigorous process, I aimed to become, in essence, the world’s foremost expert on my own optimal dietary needs.
Diet Breakdown: Six Trials in the Food Arena
The Abs Diet (Weeks 1-8)
Creators: David Zinczenko and Ted Spiker
Core Concept: A six-pack is often indicative of overall health.
Dietary Approach: High protein, healthy fats, elimination of refined carbohydrates. Workouts designed to target abdominal muscles are integral.
Key Lesson: Healthy meals can be both delicious and effortlessly prepared.
David Zinczenko, editor-in-chief of Men’s Health and the mind behind the Eat This, Not That! book series, champions a practical approach to healthy eating. While some diet gurus rely on complex jargon and convoluted advice, Zinczenko excels at presenting sound nutritional principles in an accessible, user-friendly format. The Abs Diet emphasizes whole foods and a structured eating schedule of three smaller meals and three substantial snacks daily. Zinczenko promises weight loss and improved physique through this regimen, boosted by protein intake and a dedicated workout plan.
My shopping list for this phase was straightforward: peanut butter, chicken breasts, whole-grain bread, tomato sauce, spinach, milk, eggs. Recipes were designed for speed, rarely exceeding 20 minutes of prep time. Breakfasts were primarily smoothies, and lunch/dinner recipes yielded extra portions, ideal for freezing or refrigerating – a boon for time-constrained individuals. This diet effectively dispelled the common myth that healthy eating is overly complicated and time-consuming.
A crucial takeaway was the strategic use of snacks. Instead of reacting to hunger pangs, I used snacks proactively to prevent hunger. A handful of nuts, a slice of melon, or peanut butter toast consumed a couple of hours post-meal kept my energy levels stable throughout the day, ensuring I was adequately fueled for workouts.
The Paleo Diet for Athletes (Weeks 9-16)
Creators: Loren Cordain and Joe Friel
Core Concept: Eat like our Paleolithic ancestors.
Dietary Approach: Abundant game meats, raw produce, strict avoidance of refined foods, except for endurance sports fuel (bars, bagels, gels).
Key Lesson: Constant hunger can significantly hinder exercise performance and overall well-being.
The Paleo Diet, championed by Loren Cordain, and tailored for athletes by endurance coach Joe Friel, advocates mimicking the eating habits of Stone Age humans. I now understand the fervent dedication of Atkins diet followers to meat-centric lifestyles. On this plan, I lost six pounds, and my body fat decreased from six to five percent. However, I also empathize with the irritability often associated with low-carb diets. For most of the Paleo phase, I felt consistently underfueled, fatigued, mentally foggy, and perpetually hungry.
The permitted foods – elk, buffalo, salmon – were undeniably flavorful. However, the recipes often required advanced culinary skills and a tolerance for organ meats (which I largely avoided, skipping heart, tongue, and testicles). Carbohydrate intake was severely restricted unless I was actively exercising. The monotony and persistent hunger led to a diminished appetite, with meals often ending prematurely due to boredom or stomach discomfort. Exercise became something I looked forward to, not just for physical benefits, but as an excuse to consume a granola bar for much-needed carbohydrates.
Co-author Joe Friel acknowledged initial weakness in the first two weeks but reported adaptation by week three. For me, it took closer to six weeks to feel somewhat normalized. Midway through, I succumbed to an overwhelming craving and purchased a breakfast burrito loaded with eggs, cheese, and potatoes, confessing in my food diary: “Woke up with a hunger way beyond what the fruit and vegetables in my house could cover.”
Despite the challenging experience, there were positive outcomes. My ratio of good to bad cholesterol – a potentially more critical indicator than total cholesterol – was among the best recorded throughout the year. The Paleo approach clearly has merit. However, for an active individual not aiming for weight loss, a diet that induces constant hunger and fatigue is simply unsustainable.
The Mediterranean Prescription (Weeks 17-24)
Creators: Angelo Acquista with Laurie Anne Vandermole
Core Concept: Longevity and vitality through Sicilian eating habits.
Dietary Approach: Fresh produce, legumes, nuts, whole grains, fish, olive oil, and red wine.
Key Lesson: Healthy eating is about moderation, not deprivation.
This diet has become a lifelong nutritional cornerstone for me. The Mediterranean Prescription, focusing on the fish-and-produce-rich cuisine of Sicily and surrounding Mediterranean cultures, offered culinary delights like swordfish with capers, pasta fagioli, and poached pears in Chianti. Even with limited cooking experience, I found the recipes straightforward. As an endurance athlete, the pasta-centric approach resonated deeply; pasta has long been a staple fuel for runners and cyclists. I felt energized and performed exceptionally well on my bike.
The underlying principles are scientifically sound. A study comparing moods of low-carb versus low-fat dieters revealed that low-fat dieters reported significantly better emotional well-being after a year. The Mediterranean Prescription served as a potent reminder that while refined carbohydrates have negatively impacted American health, this is not a justification to eliminate all carbs. While white bread should be minimized, whole-grain options are beneficial. Dipping whole-grain bread in olive oil has become a regular, satisfying afternoon snack.
I also appreciated the book’s perspective on calories. Acquista explicitly states that calorie counting is counterproductive to long-term healthy lifestyle changes. His core message is simple yet profound: prioritize vegetables, embrace healthier versions of familiar foods, and engage in enjoyable physical activities. He also underscores the importance of festive meals and relaxation. If weight gain occurs, adjust by eating less and exercising more – a balanced, sensible approach I wholeheartedly endorse.
The Okinawa Program (Weeks 25-32)
Creators: Bradley J. Willcox, D. Craig Willcox, and Makoto Suzuki
Core Concept: Eating habits of the world’s longest-lived population.
Dietary Approach: Predominantly plant-based, with chicken, fish, unrefined carbohydrates, and ample soy products.
Key Lesson: Conventional dietary wisdom can sometimes be misleading.
The authors, scientists and clinicians with extensive research on Okinawan longevity and diet, present a slightly modified version of traditional Japanese cuisine. Having lived in Japan for six years, I was already a fan of Japanese food and had high expectations for this diet.
However, the results were surprising and somewhat alarming. Despite feeling healthy, energetic, and enjoying every meal, my total cholesterol surged by 43 points, good cholesterol (HDL) decreased, and body fat increased. My doctor cautioned that if the next diet didn’t improve my cholesterol levels, medical intervention would be necessary.
What went wrong? Soy might be a contributing factor. Research, summarized in The Whole Soy Story, suggests that excessive soy consumption can pose health risks, including hormonal imbalances. While my experiment was self-guided and anecdotal, my subsequent dietary phase suggested that while the Okinawa Program might be ideal for Okinawans who have evolved over generations to thrive on this diet, my European ancestry might be better suited to Western European dietary patterns.
Nutritionist (Weeks 33-40)
Creator: Laurent Bannock
Core Concept: Personalized diet based on ancestry.
Dietary Approach: Balanced protein, fats, and carbs, but from a food list tailored to individual DNA.
Key Lesson: A truly personalized diet can be transformative.
Working with nutritionist Laurent Bannock, who specializes in ethnicity-based dietary strategies, was a revelation. The premise is that as human populations migrated and evolved globally, their digestive systems adapted to local foods. Bannock tailors dietary recommendations based on ancestry, individual factors like weight, allergies, and activity levels. For individuals of East Asian descent, the diet closely resembles the Okinawa Program. For my Irish heritage, Bannock recommended limiting or eliminating chicken, tomatoes, coffee, soy products, and all dairy.
The results were undeniable. My blood profiles improved, body composition leaned out, sleep quality enhanced, and energy levels remained consistently high throughout the day. This echoed my positive experience with Bannock’s personalized plan two years prior.
The main challenge was eating out. The extensive list of restricted foods made restaurant dining difficult. Fortunately, Bannock advocates for occasional “cheats,” acknowledging the social and psychological benefits of enjoying forbidden foods in moderation.
MyPyramid.gov (Weeks 41-48)
Creator: USDA
Core Concept: Free, interactive online tools for personalized nutrition guidance.
Dietary Approach: The often-criticized USDA Food Pyramid.
Key Lesson: Detailed food tracking significantly enhances dietary awareness.
For the final phase, I opted for a more self-directed approach using the USDA’s MyPyramid.gov website (now ChooseMyPlate.gov). This platform offers interactive tools that, when used together, approximate a free virtual nutritionist. Users input age, weight, height, and activity level to generate daily caloric targets and recommended servings from five food groups: grains, vegetables, fruits, dairy, and meat/beans. Logging food intake and exercise allows users to track progress against these targets visually.
While the site effectively promotes dietary awareness, I had reservations about some of the USDA’s recommendations. The USDA must cater to diverse stakeholders, including medical organizations, government panels, and agricultural lobbies. While calorie targets seemed reasonable, some food recommendations appeared questionable. The recommendation of three or more cups of milk daily, for instance, seemed excessive and potentially problematic for many.
However, the site excelled at forcing mindful eating. It quickly highlighted the challenge of consuming sufficient produce and the rapid accumulation of calories, fats, sodium, and cholesterol. For someone starting their health journey, this site could be a valuable resource. For me, with a year of intensive dietary experimentation, the generalized guidelines felt like a step backward.
After a year immersed in the diet industry, I can’t definitively say how you’ll react to any single diet. However, I can offer a strategy for discovering what works best for you.
Finding Your Food Formula: The Elimination Diet Strategy
What were the ultimate learnings from this year-long “man vs food food” challenge? Lean protein, healthy fats, and wholesome carbohydrates are foundational. More specifically: moderately sized meals rich in produce, occasional lean meats, and minimally processed whole grains. Olive oil is beneficial, and nuts and dates make excellent snacks.
This broad framework is generally beneficial. However, individual nuances are critical. I discovered that wheat is not problematic for me, but dairy and tomatoes are. Your individual responses may differ drastically. The Okinawa Program might be life-changing for some; the Paleo Diet for Athletes could enhance athletic performance for others. Individual reactions to diets are highly variable.
My key takeaway, after a year navigating the diet landscape, is a personalized strategy rooted in what’s commonly known as an elimination diet. This involves keeping a food diary to track intake and corresponding physical and mental states. The process, while intensive, takes closer to two months, not a full year.
The initial two weeks are the most demanding. Eliminate all processed foods, coffee, dairy, nightshades, wheat, soy, alcohol, corn, eggs, processed grains, added sugar, and non-organic, non-free-range, non-grass-fed meats. Despite these restrictions, numerous options remain, primarily within the produce section. Incorporate fish, turkey, or buffalo occasionally, drink herbal tea, explore spelt bread, and learn to cook quinoa. This initial phase is manageable.
Subsequently, systematically reintroduce eliminated foods one at a time, observing reactions over the next 72 hours. Does an omelet induce nausea? Do tomatoes trigger skin issues? Does meat improve satiety? This methodical process reveals food sensitivities and beneficial foods. After two months, you’ll have a clearer understanding of your optimal dietary profile. Ideally, consult your doctor for blood tests before and after the two-month period to quantify the impact.
Finally, a crucial piece of advice: cheat strategically. Allow yourself occasional indulgences. Knowing you can enjoy your favorite treats occasionally makes adhering to a healthy diet more sustainable long-term.
This approach, while not rigorously scientific, is likely more personalized and effective than generic diet plans. I believe it can empower you to conquer your own “man vs food food” challenges and discover a truly sustainable and health-promoting way of eating.
