Quick Summary

A guide to Gary Brecka's diet, highlighting recommended whole foods including grass-fed meats, healthy fats, and low-glycemic vegetables. Focuses on the 30-30-30 rule and foods to avoid for metabolic optimization.

Key Points

Prioritize Whole Foods: The foundation of the diet is avoiding processed junk and focusing on real, recognizable, and nutrient-dense whole foods.
Embrace Healthy Fats: Make high-quality fats from sources like avocado, olive oil, and animal products your primary energy source.
Focus on Clean Protein: Consume moderate amounts of high-quality protein from grass-fed meats, wild-caught fish, and pasture-raised eggs.
Implement the 30-30-30 Rule: Start your day with 30 grams of protein within 30 minutes of waking, followed by 30 minutes of low-intensity exercise.
Limit Carbohydrates: Restrict carbs to low-glycemic, non-starchy vegetables and a small amount of berries to avoid insulin spikes.
Avoid Inflammatory Foods: Strictly eliminate refined sugars, processed seed oils, white rice, and sweetened yogurts from your diet.

The Foundation: A Whole-Food, Ketogenic Approach

Gary Brecka's nutritional advice is part of a larger biohacking philosophy focused on achieving peak human performance and longevity. His diet centers on a high-fat, low-carbohydrate, moderate-protein plan to induce ketosis, where the body burns fat instead of glucose for energy. This approach prioritizes personalized nutrition using whole, unprocessed foods and eliminating inflammatory, ultra-processed items.

High-Quality Proteins

Protein is crucial in the Gary Brecka diet, particularly with the 30-30-30 rule recommending 30 grams within 30 minutes of waking. This can help stabilize blood sugar. Protein sources should be high-quality and whole.

Recommended Protein Sources

Grass-fed beef: Options like ground beef and ribeye steak.
Wild-caught fish: Such as salmon, known for omega-3 fatty acids.
Pasture-raised eggs: A versatile and nutritious choice.
Organic poultry: Including chicken and turkey.
Full-fat dairy: Plain, organic Greek yogurt and creamy cheeses are acceptable if unsweetened.
Soy-free, vegan protein: Recommended as an alternative to whey protein.

Healthy Fats

Healthy fats are the primary energy source in this ketogenic diet, making up a significant portion of daily calories. They provide sustained energy, support hormones, and aid vitamin absorption. Focus is on healthy saturated and monounsaturated fats, avoiding inflammatory seed oils.

Recommended Fat Sources

Avocado and avocado oil: Good sources of monounsaturated fats.
Olive oil: Extra-virgin olive oil is a key component.
Coconut oil, ghee, and grass-fed butter: Healthy saturated fats suitable for cooking.
Nuts and seeds: Consumed in moderation.

Low-Glycemic Carbohydrates

Carbohydrates are limited but included from nutrient-dense, low-glycemic sources to prevent insulin spikes.

Recommended Carbohydrate Sources

Non-starchy vegetables: Leafy greens, broccoli, asparagus, Brussels sprouts, squash, and bell peppers are examples. Flash-frozen organic vegetables are also recommended.
Berries: Low-carb fruits like raspberries, blueberries, blackberries, and strawberries.

Foods to Avoid on the Brecka Diet

Eliminating certain foods is crucial. The plan avoids processed foods that can cause inflammation and metabolic issues.

Key Foods to Eliminate

Refined sugars: Known to cause insulin spikes and inflammation.
Processed seed oils: Such as canola and soybean oil.
White rice and other refined grains: White rice offers little nutritional value.
Flavored yogurt: Often contains high added sugars.
Non-organic vegetables: To avoid pesticides.

Brecka-Approved vs. Typical Western Diet Comparison


Feature	Brecka-Approved Diet	Typical Western Diet
Core Principle	Whole, unprocessed foods	Processed, packaged foods
Primary Fuel Source	Healthy fats (ketosis)	Refined carbohydrates (glucose)
Protein	High-quality, clean sources (grass-fed, wild-caught)	Often low-quality, factory-farmed meats
Fats	Healthy, stable fats (avocado, olive, coconut oil)	Inflammatory seed oils (canola, soybean)
Carbohydrates	Low-glycemic, nutrient-dense veggies/berries	High-glycemic, refined grains, added sugars
Inflammation Level	Low	High

Integrating Lifestyle Practices

Beyond food, the diet incorporates biohacking practices. Hydration with clean water is vital, and intermittent fasting can complement the eating pattern. The diet can be personalized with genetic testing.
