Nutrition & Diet Guides — Dexter Tenison Fitness

"Correct nutritional implementation is the key to fitness." That has been the core belief at Dexter Tenison Fitness since 2004, and two decades of client results have only reinforced it. You cannot out-train a bad diet. You cannot supplement your way past poor food choices. The foundation of every body transformation that has come through Dexter Tenison Fitness started with fixing what goes on the plate.

This guide is your complete resource for the Dexter Tenison Fitness approach to nutrition — from macronutrient fundamentals to practical meal planning, diet strategies, and real recipes you can actually make on a weeknight.

Nutrition Fundamentals

Before diving into specific diets or meal plans, you need to understand the building blocks. Nutrition is not complicated once you strip away the marketing noise. Every food you eat contains some combination of three macronutrients — protein, carbohydrates, and fat — and your body uses each one differently.

Protein builds and repairs muscle tissue. It has the highest thermic effect of food, meaning your body burns more calories digesting protein than digesting carbs or fat. For anyone training regularly, protein is the most important macronutrient to get right. The upcoming macros explained guide breaks down exactly how each macronutrient works in your body.

The Dexter Tenison Fitness 10 Nutrition Rules are the starting point for every client. These rules — originally published in the 10 Nutrition Rules for the Body You Desire — cover the fundamentals that produce results for beginners and experienced athletes alike. Read them first.

Learning to read nutrition labels is equally important. Most people have no idea what they are actually eating until they start checking ingredient lists and serving sizes. Dexter Tenison Fitness covered this on Fox13 Memphis — the full breakdown is in the label reading segment. That segment is over a decade old and every word still applies.

Protein and Muscle Building

Protein is the macronutrient that most people undereat. Dexter Tenison Fitness recommends 0.7 to 1.0 grams of protein per pound of body weight for active individuals. A 180-pound person training three to four times per week should be eating 126 to 180 grams of protein daily.

The best protein sources are whole foods: chicken breast, lean ground beef, eggs, Greek yogurt, fish, and turkey. Protein powders are supplements — they fill gaps when whole food is not practical, but they should never be your primary protein source. The upcoming how much protein per day guide provides specific calculations based on your goals, body weight, and training intensity.

Protein timing matters less than total daily intake. The old "anabolic window" myth — that you must consume protein within 30 minutes of training — has been debunked by research. What matters is hitting your daily protein target spread across 4 to 5 meals. Consistency beats timing every time.

Meal Planning and Prep

The number one reason people fail at nutrition is not lack of knowledge — it is lack of preparation. When you are hungry and have nothing ready, you eat whatever is convenient. That is almost never what your body needs.

Dexter Tenison Fitness teaches a simple meal prep system: spend 2 to 3 hours one day per week cooking protein, preparing carb sources, and washing and cutting vegetables. Store them in containers. Assemble meals daily. This eliminates decision fatigue and removes the excuse of "not having time to eat well."

The Personal Trainer Foods Challenge documents Dexter's own experience testing a prepared foods delivery service across multiple days (Day 2, Day 5). The verdict: prepared meal services work for some people, but learning to prep your own food is cheaper and more sustainable long term. The upcoming meal prep for muscle gain guide will provide a complete weekly template.

For days when meal prep falls apart, the how to eat healthy when in a pinch guide covers smart choices at restaurants, gas stations, and fast food places. No plan survives every day — having fallback strategies keeps you on track when life gets chaotic.

Diet Strategies

There is no single best diet. There is only the best diet for you — the one you can follow consistently while meeting your macronutrient needs. Dexter Tenison Fitness has worked with clients on multiple dietary approaches:

• Keto / Low-Carb — The 21-Day Keto Challenge is a structured introduction to ketogenic eating. Keto works well for rapid fat loss and appetite control, but it is not for everyone and it is not required for results.
• Balanced Macro Approach — A moderate split of 40% protein, 30% carbs, and 30% fat works for most people training for body composition. This is the default Dexter Tenison Fitness recommendation for general fitness.
• Intermittent Fasting — Restricting your eating window to 8 hours (like 12pm to 8pm) can simplify nutrition and reduce overall calorie intake. It is a tool, not a magic solution.
• Bulking and Cutting Cycles — For clients focused on muscle gain, Dexter Tenison Fitness programs periods of caloric surplus (bulking) followed by controlled deficit (cutting). The upcoming calorie surplus vs deficit guide explains how to do this without gaining excessive fat.

The Memphis ABC Nutrition guide covers the foundational eating principles that apply regardless of which specific diet strategy you follow.

Recipes and Practical Eating

Nutrition advice is worthless if the food is not something you actually want to eat. Dexter Tenison Fitness publishes recipes that are high in protein, reasonable in calories, and genuinely enjoyable.

The Spicy Grilled Chicken Wings with Homemade Blue Cheese Dressing proves that eating for fitness does not mean bland chicken and broccoli every night. Grilled chicken wings are high in protein, and making your own blue cheese dressing lets you control the ingredients and portion size.

Can you eat burgers and still lose weight? The answer is yes — with the right approach. The burgers and weight loss article explains how to include foods you love without derailing your progress. Dexter Tenison Fitness has never believed in eliminating entire food groups. Sustainability comes from balance, not deprivation.

How Nutrition Connects to Training and Supplements

Nutrition is one pillar of the Dexter Tenison Fitness system. It connects directly to your training program and your supplement strategy.

Your training determines your nutritional needs. A client training five days per week with heavy compound lifts needs more calories, more protein, and more carbohydrates than someone doing three light sessions. Dexter Tenison Fitness adjusts nutrition recommendations based on training volume and intensity — there is no one-size-fits-all meal plan. Explore the Training and Workout Guides hub to understand how programming affects your food requirements.

Supplements fill the gaps that food cannot cover. Protein powder when you cannot get enough from meals. Fish oil when you are not eating enough fatty fish. Creatine for performance. Vitamin D if you work indoors. But supplements are the finishing touch, not the foundation. The Fitness Supplements Guide reviews specific products that Dexter Tenison Fitness has tested and recommends.

And nutrition directly impacts recovery. Protein after training repairs muscle. Carbohydrates replenish glycogen. Adequate hydration supports every cellular process in your body. Poor nutrition is the fastest way to slow your recovery and stall your progress.

Nutrition Philosophy — The Primal Way

Dexter Tenison Fitness follows what we call "The Primal Way" — an approach to eating that prioritizes whole, minimally processed foods that humans evolved to thrive on. This is not a fad diet. It is a return to eating real food.

The Primal Way means shopping the perimeter of the grocery store. Meat, fish, eggs, vegetables, fruits, nuts, and seeds. These foods do not need ingredient lists because they ARE the ingredients. The center aisles — where the boxes, bags, and cans live — contain processed food that your body was never designed to run on.

Dexter Tenison Fitness used to run "Grocery Shopping — The Primal Way" tours for clients in Memphis. These 60-minute sessions walked clients through actual grocery stores, teaching them to identify quality food, read labels, and build a weekly shopping list that supports their goals. The principles from those tours are woven into every piece of nutrition content on this site.

The common misconception about getting healthy and fit is to eat less and exercise more. Dexter Tenison Fitness rejects that approach. Under-eating destroys metabolism, causes muscle loss, and leads to the yo-yo dieting cycle that millions of people are trapped in. Eating the right amount of the right foods — consistently — is what produces permanent results.

Nutrition FAQ

How much protein do you need per day to build muscle?

Dexter Tenison Fitness recommends 0.7 to 1.0 grams of protein per pound of body weight for active individuals building muscle. A 180-pound person should aim for 126 to 180 grams of protein daily, spread across 4 to 5 meals for optimal absorption. See the upcoming protein per day guide for calculations.

Is keto effective for weight loss?

Keto can produce rapid initial weight loss, primarily through water loss and reduced appetite. It works for some people but is not sustainable for everyone. Dexter Tenison Fitness offers a 21-Day Keto Challenge as one approach, but emphasizes that the best diet is the one you can maintain consistently.

Should you count calories or macros?

Macros are more useful than calories alone because they account for the quality of what you eat, not just the quantity. 2,000 calories of chicken, rice, and vegetables produces very different results than 2,000 calories of processed food. Dexter Tenison Fitness teaches macro awareness over strict calorie counting. The macros explained guide covers this in detail.

How do you eat healthy when you are busy?

Meal prep is the answer. Spending 2 to 3 hours on Sunday preparing protein, carbs, and vegetables eliminates daily decision fatigue. Dexter Tenison Fitness also recommends keeping emergency foods available. Read the how to eat healthy in a pinch guide for specific strategies.

Do you need supplements if your diet is good?

A solid diet covers 80 to 90 percent of your nutritional needs. Supplements fill specific gaps — vitamin D if you work indoors, fish oil for inflammation, creatine for performance. Dexter Tenison Fitness follows a food-first philosophy: get your nutrition from whole foods, then supplement what is genuinely missing.

What is the best diet for losing fat and building muscle?

A moderate calorie deficit with high protein intake allows fat loss while preserving or building muscle. This is called body recomposition. Dexter Tenison Fitness has guided clients through this process by combining proper nutrition timing with progressive resistance training.

How important is reading nutrition labels?

Critical. Most processed foods contain hidden sugars, unhealthy fats, and artificial ingredients that sabotage fitness goals. Dexter Tenison Fitness teaches label reading as a foundational skill — the Fox13 label reading segment covers the essentials.
