Improving Gen❌ performance with the latest methods in evidence based ketogenic sports nutrition

At almost 50 years old, I have several years of experience in health and fitness. As a Physical Fitness and US Army Combatives instructor and as the owner of a health and fitness studio, I have spent many years helping people improve their health and physical performance. Through my own experience and struggle with managing my weight and trying to find the best way to stay strong and active as I get older, I've learned valuable lessons that I've built into Ultimate Ketogenic Fitness.

There have been dozens of studies looking at ketogenic nutrition and sports performance. Almost none of them show direct increase in performance within the time frames of the research performed. All of them show some improvement in metabolic performance and efficiency that indicates great potential for improvements in training capacity and physiological resilience.

If the scientific community is really going to understand ketogenic sports nutrition, there has to be a shift in acknowledging the secondary long-term impacts of metabolic flexibility and improved inflammation management.

Research interventions need to be longer and interpretation of data needs to be consistent with the physiological context of ketogenic adaptation.

Common mistakes athletes make when they follow a ketogenic diet.

1. Eat less food. Ketogenic nutrition tends to increase satiety and some athletes need to intentionally focus on maintaining their overall protein and fat intake.
2. Focusing on fat and not protein. Yes you need fat but a ketogenic diet does not mean fat is the priority. Performance and growth require protein.
3. Not increasing their electrolytes and hydration. Ketogenic diets increase the bodies removal of electrolytes. It is important to make sure to increase your intake to help maintain performance.
4. Not giving adaptation enough time. This is probably the biggest mistake I see athletes make. In most cases, yes, transitioning to ketogenic nutrition is going to suck. Data shows it's going to take at least 6 to 8 weeks before you start seeing a return to baseline. Improvements in performance often take 12 or more weeks to show up.

If you've tried keto before and said it didn't work for you, look back and see if you did one of these things. It might be worth trying again to see what happens.

If you don't understand this concept, then you don't understand sports nutrition.

Ratios are inadequate constructs for determining nutrition because they are, 1. Based on calories which don't exist in human biology, 2. Ignore nutrition and the impact food has on biological function, and 3. Disregard bio-individual requirements and needs.

You will see much better performance and simplify your nutrition lifestyle when you recognize that "adequate" is the goal not some textbook formula that doesn't work in real life. Stop tying your fat intake to your protein intake and vice versa. They do different things in your body and are not interdependent factors.

You need adequate protein, adequate fat, adequate sleep, adequate stimulus to your muscles, adequate.......

There is no perfect solution. You have to figure out what you need and what will work.

I started following a carnivore diet while I owned a CrossFit gym. Within 6 months of cutting out all plants and getting minimal carbs from cheese and eggs, here's what happened.

🔥 PR's in strength tests
🔥 PR's in benchmark WODs
🔥 Doubled my workout volume
🔥 Halved my recovery time
🔥 Eliminated chronic aches and pains

Not only is this my experience but I have worked with hundreds of people over the past several years and duplicated this experience with each and every one of them.

Not saying that ketogenic diets are the answer to everything, but I am saying it would be a mistake to completely dismiss them because of old paradigms and biased science.

Everyone deserves the right to find out for themselves if there's anything in ketogenic nutrition for them. Comment ebook below and I'll send you the Ketogenic Athletes Playbook so you can try it for yourself.

It amazes me how exercise scientists will argue against a ketogenic diet because it supposedly doesn't allow the body to replenish glycogen stores. Those same exercise scientists also recommend upwards of 700g to 900g carbohydrates per day to make sure that glycogen stores are topped off at all times.

There is a hyper-fixation on making sure that energy stores are adequate, yet all sports nutritionists and exercise scientists recommend pre-workout carb loading to provide immediate energy for exercise...🤦

Which one is it? Should athletes be preloading energy or accessing stored energy. This is a perfect example of the disconnet between current guidelines and actual physiological mechanisms.

Your body has enough energy to supply multiple days of high intensity effort, even if you didn't eat a single piece of food.

A ketogenic diet does not limit access to energy. It forces improved access to energy and more efficient energy management within your physiology. If you want to improve metabolic flexibility and long-term sustainable energy even at high intensities, a ketogenic diet will get you there faster than anything else.

Facts.

Prove me wrong.

Contrary to what you may have heard when it comes to actual objective performance measures ketogenic adaptation does not decrease performance. It doesn't matter if you were talking about CrossFit, strength training, bodybuilding, traditional ball sports, or endurance sports.

Common issues with most research that claims ketogenic diets are detrimental to sports activities.

1. Adaptation was not long enough
2. The intervention was not truly ketogenic
3. Conclusions based on metabolic proxies not objective outcomes
4. No accounting for the impact of adaptation on hydration or electrolyte balance
5. Poor understanding of metabolic adaptations and inadequate wash over periods

Almost 8 years coaching ketogenic sports nutrition and I can confirm clinically that ketogenic nutrition is a net positive for athletes performance and quality of life.

I know this isn't a popular sentiment in some circles. That doesn't make it any less true. The role that men play in society requires strength.

"Hard times create strong men. Strong men create good times. Good times create weak men. And, weak men create hard times."

Now more than ever we need strong men. Weakness has been glorified for far too long.

Your metabolism does not work like an on and off switch. There are a dozens of factors and variables tied to the adaptive response of your metabolism to your habitual diet.

Most washout periods between nutrition interventions are no more than 7 days. This is hardly enough time to claim that performance measures are causally impacted by a nutrition intervention.

The idea that there is any such thing as a neutral diet is categorically flawed. It is impossible to take a carb fueled athlete, give them a carb-based nutrition intervention, have them go back to a habitual diet for a week, and then evaluate a ketogenic nutrition intervention and make causal inference on the outcomes.

The entire process of how washout periods are designed needs to be rethought from the ground up.

This issue alone makes most conclusions about ketogenic nutrition in sports performance highly unreliable.

I finished working with my last one on one client about 6 months ago. I stopped running my group programs about 2 years ago. I've been in the process of transitioning to writing books, public speaking, and focusing on research and publications.

I was planning on transitioning away from the identity of Coach Bronson.

Here's the problem. People keep asking for help. Especially men who are often overshadowed by the abundance of women in the health and fitness space.

Ask any coach or influencer and they will tell you their audience is easily 70% or more women, even if they haven't focused on that demographic.

But I know there are men out there who are looking for more out of themselves and their life experience. I get DMs on the regular from them. I continually have women asking questions for their partners.

As much as I want to focus on the science and changing the foundation of institutional knowledge. I'm finding it very difficult to step away from my calling as a coach. As a man, I know what it's like to feel like you have more to offer, but not know how to get there.

Something is in the works. I don't know exactly what it is or how it will come together. If you are a man who is interested in building strength and becoming a more capable version of yourself, comment here or shoot me a DM and let me know if you would like some help.

You aren't getting tired in your workouts because of lack of carbs in your stomach.

There are three things you can focus on to improve your endurance, stamina, and performance.

1.Fat adaptation improves metabolic flexibility and increases access to stored energy, helping maintain stable fuel availability for the brain during exercise.

2.Sleep directly affects brain function. Even losing a couple hours can impair reaction time, motor control, and perceived effort during training.

3.Electrolyte balance supports neural signaling and muscle contraction. When sodium, potassium, and other electrolytes are low, the nervous system cannot transmit signals efficiently.
