The Conor McGregor diet clearly yields some impressive results. In this post we’ll take a deep dive into the way Conor eats, and the coaches who have had an influence on this. Of course, its important to note up front that he works out LOADS compared to your average Joe, so that’s a huge factor as to his physique. But… after digging into his diet – he does some interesting stuff that we can all learn from.

Conor has some general dietary principles he follows, which he laid out in a Men’s Health interview:

“I don’t eat takeaways. I don’t eat none of that shit.

I’ll eat good-quality meats, good-quality greens, good-quality carbohydrates like sweet potato and butternut squash, and that is it.”

As we’ll go into detail later on, Conor primarily eats:

  • Grilled or baked meat & fish
  • Plenty of fresh vegetables, in particular greens
  • Complex carbohydrates
  • Fruit & nuts (sparingly)

And it’s not just what he eats, it’s also the timing (keep reading to learn more).

But he admits he has a weakness:

“I have a sweet tooth — that would be where I’d put on some weight out of fighting, if somebody brings in a pack of cakes and coffee.”

To dig a bit deeper into Conor’s diet, we need to go back to the sources.

His original key dietary influence was his head coach John Kavanagh. Then John Kavanagh got George Lockhart in to take over – George would plan & prepare all Conor’s meals during a fight camp.

George has managed Conor’s diet since UFC 194, including for the recent Mayweather fight. George has also coached the likes of Jon Jones, Rory MacDonald and Dustin Poirier with their diets.

Examples of Conor McGregor’s Meals

Before we dig into the details, lets look at the types of meals Conor eats:

Conor’s dinner – chicken with green beans. According to a video Conor also posted, those brown things that look like potatoes are a kind of peanut butter energy ball.

Examples of Conor’s Meals, Prepped by Diet Coach George Lockhart

These are all meals that George prepped for Conor in the lead up to his 2017 fight with Floyd Mayweather. These are in chronological order, with the last meal about a month out from the fight. Therefore none of these meals were used when Conor was prepping for weigh-ins.

Conor’s Diet Foundations

Before Conor started working with MMA diet expert George Lockhart for UFC 194 – he already had a solid influence for how to eat.

His head coach, John Kavanagh, who Conor has trainer with his whole professional career, has a very simple approach to diet, which he shared with Bloody Elbow:

“You know, a diet is super simple. I can tell you mine right now in one sentence. If it had a face or it grew, then it’s pretty much okay, and stay away from processed food. It’s just that simple.”

And again, in a tweet (below) John further emphasises this strategy, showing a fridge full of healthy foods:

Whilst John Kavanagh isn’t as well known in MMA circles as Greg Jackson or Firas Zahabi – he nonetheless has achieved phenomenal success as Conor’s lead coach.

In addition to this, Conor approaches everything with a students mindset. In February 2016, he posted on Instagram that he was reading the Sirt Food Diet:

Conor on Instagram: “I’m eating like a king these days. #thesirtfooddiet

Conor doesn’t appear to follow the diet strictly. For example, in the lead up to recent fights, his diet coach George Lockhart has complete control over his diet. Thus, its reasonable to believe that Conor was simply reading the Sirt food diet to educate himself, rather than following it religiously.

The idea behind the sirt diet is that there are certain foods which activate sirtuin proteins. These sirtuins are said to:

  • Protect cells in the body from dying when they are under stress
  • Help regulate inflammation and the aging process
  • Influence the body’s ability to burn fat

Sirt foods include things like green tea, dark chocolate (85% cocoa content or greater), turmeric, kale and blueberries. It’s likely that Conor has integrated some of these into his diet since.

Enter George Lockhart – Conor’s Diet Coach

Three weeks out from Conor’s first fight with Jose Aldo (UFC 194), Conor’s Head Coach; John Kavanagh reached out to diet expert George Lockhart to see if he could help Team McGregor. That collaboration led to the easiest weight cut (to 145lbs) Conor has had, and they’ve worked together since. Not only a nutritionist, George is also a former US marine and MMA fighter.

Conor & George

The way George works with fighters is to come into their training camp, and take complete control of their diet in the lead up to weigh ins. In an interview with Ariel Helwani, George explains how he goes shopping 4-5 times per day when preparing food for Conor. He explains that he has to be flexible, based on what kind of training Conor is doing that day, and what weight he’s at, he’ll cook and prepare different things:

Generally speaking, George’s diet principles are the same as we discussed at the start. He focuses on good quality meats, fish, vegetables and complex carbohydrates. He isn’t afraid of simple carbohydrates; but emphasises they should be reserved for post workout recovery.

Below we’ll dig into how George looks at macronutrient food timing to optimise our hormones; insulin and glucagon. I’ll explain in my own words, because I haven’t found a good source where George explains it from the ground up! Although if you browse his various videos on YouTube it amounts to the below (más o menos).

George on Insulin & Glucagon for Training

Insulin is the major energy storage and growth hormone we can trigger through diet. Specifically, through the consumption of glucose containing foods such as simple and complex carbohydrates.

George’s general approach to carbohydrates is that “most people” don’t need a lot of them, because they’re not doing a lot of physical exercise. And definitely most people don’t need a lot of simple carbohydrates and sugars. But in the case of athletes who often train 3x per day, they need carbohydrates (to stock up their glycogen stores) for their explosive training movements, and thus the focus is on the types and timing of them.

The way George times carbohydrate intake is to spike insulin after a workout, rather than before.

This has the benefit of signalling to the muscle cells and liver to replenish energy stores and start the muscle repair process.

In practical terms, this means avoiding simple carbohydrates before a workout (saving them for the post-workout refuel).

Instead, pre-workout, he uses protein or fruits (fruits contain both fructose and glucose). Whilst fructose is a sugar, it doesn’t cause an insulin spike, instead being metabolised in the liver. Thus the fruit is useful because it boosts liver glycogen stores (useful for explosive exercises), without causing a large spike in insulin, that you would get from simple carbohydrates like bread, rice and pasta.

Specific fruit examples George uses are apples, blackberries, strawberries & grapefruit (source). And then if there is a longer time period pre-workout, enough to get a meal in, he might opt for vegetables to accompany the protein such as spinach, broccoli & asparagus.

A hormone that does the opposite of insulin, is called glucagon. Whilst insulin operates by lowering blood glucose, shunting it into muscle and fat cells, glucagon instead signals to the body to release glucose and lipids into the blood stream for use.

Insulin is actually an inhibitor of glucagon. Thus, if you consume simple sugars pre-workout, and want your body to have quick access to energy stores, having high circulating levels of insulin dampens your glucagon release. Thus it makes more sense to consume protein and fructose sources immediately pre-workout. Of course, if you’ve got 2-3 hours before your workout, you can consume glucose containing foods without them interfering with glucagon release – this is because your insulin will have dropped back down to normal levels by the time you work out.

Conor’s Supplements

As we’ve discussed above, Conor tries to get all his nutrient needs from “real foods”, rather than resorting to too many supplements. That being said, he has discussed using BSN shakes for post-workout recovery. In his Twitter post on the subject he didn’t mention the specific BSN product, but there’s a high chance it’s their popular R3Build Edge Post Workout Recovery powder, with contains goodies like creatine, glutamine and BCAAs.

Conor’s Routines

  • On Waking
    First thing Conor does on waking is stretch and drink water to rehydrate after sleep
  • Before Breakfast
    Conor often does fasted cardio after waking, before eating his first meal
  • Breakfast
    After stretching or fasted cardio, Conor drinks a coffee and has breakfast. Breakfast is mainly protein, fat and vegetables. Waiting until post-workout to really refuel with carbohydrates.
  • Pre-workout
    If Conor needs energy pre-workout, Conor’s diet coach (George Lockhart) recommends he eats protein or fruit, which shouldn’t trigger a big insulin dump right before he needs to workout. For fruit, George recommends fruits like blackberries, blueberries, apples, strawberries and grapefruit.

Conor on Fasted Cardio

Conor says:

I like running, I’ve been running my whole career. I always do fasted cardio. I like training on am empty stomach because… it takes you someplace. Puts you in a different mindset, you’re in… survival mode almost, you’re on the hunt.

It’s what I like doing, it brings my weight down. Then you add in the desert heat, that dry air. Then as the fight comes closer I pack more clothes on to get that extra bit off. It just adds more intensity to it.

It puts me somewhere, where I need to be for this. I’m just visualizing the moments, the sequences, there is no face I’m picturing, it’s just a blank face, and a particular body.

I’m just visualizing dominating the whole game. That’s it.

See the Youtube video below to watch Conor talking about fasted cardio:
