Golf is a difficult sport! We don’t need to make it more difficult by poorly fueling our body and brain. The best players in the world are organised about what they eat before and during a round. It is not an accident.
For club golfers, it is one of those small things you have complete control over that can have a major impact on your performance. Looking after your nutrition does not guarantee you will play well, golf is too chaotic for that, but getting it wrong leads to dropping energy, loss of concentration, and tends to make us a little moody. This is not the state you want to be in when you’re trying to maximise your chances of playing to your potential. The dreaded downward spiral is a lot more likely when running on empty.
As golf is a low intensity activity, you are not burning through carbohydrate stores the way you would playing basketball, soccer, or racing a 10k. We don’t need to “carb load” the way we would for maximum performance in those very high intensity activities. The real goal is keeping blood sugar stable, and hunger at bay throughout the round. A good mix of protein, carbohydrates, and fats works well. Mixing carbohydrate with protein and/or fat, slows the release of blood sugar and prevents the spikes and crashes that hurt your focus.
Why This Matters
Walking 18 holes means covering 5-7 miles and taking up to 15,000 steps. Even riding in a cart, a round of golf burns somewhere between 800 and 1,400 calories depending on how you play. That is a significant energy demand over four to five hours.
But the bigger issue is not the physical fatigue. It is what happens to your brain when blood sugar drops.
A four-week continuous glucose monitoring study tracking healthy adults found that participants consistently reported lower mood when hungry, with mood ratings directly tied to glucose levels. Separately, research on cognitive performance shows that drops in blood glucose impair attention, memory, and decision making.
In golf, where staying in a neutral emotional state and making good decisions on every shot is everything, this matters enormously. The downward spiral is real. A bad shot leads to frustration, frustration leads to poor decisions, poor decisions lead to more bad shots. Getting hungry accelerates that spiral and makes it harder to recover. The good news is we can reduce that risk with a little planning.
Free 10 Minute Follow Along Mobility Routine
Follow along with Mike through this free 10-minute mobility routine designed to improve range of motion between workouts.
🌙 The Night Before
Your fuelling starts the evening before, especially for early morning rounds.
- Have a decent sized dinner with carbohydrate and protein
- Drink plenty of water, especially important in hot climates
- You do not want to start the round already behind
🍳 Before You Play
Never go to the course hungry. A solid breakfast gives you stable blood sugar from the first tee.
Example Morning Meal
🥚 Scrambled eggs on whole wheat toast
🥛 Fat free Greek yogurt
☕ Coffee
💧 Water
⛳ On The Course
Eat before you get hungry. Once blood sugar drops, concentration follows. This is when the downward spiral starts, mistakes compound, mood drops, you start thinking about food instead of your game.
Good Options
🍌 Banana or apple
🥜 Small bag of nuts
🥪 Sandwich with protein
🍫 Quality protein bar
Avoid
🍬 Sweets and candy
🍫 Chocolate bars
Blood sugar spike then crash — not what you want on 17.
Especially important if walking the course or if the round is going to stretch past four hours.
💧 Hydration
- Water is all you need — electrolytes are unnecessary unless playing in extreme heat and humidity. Note the sugar content in “sports drinks”. It’s generally advisable to water them down.
- Target a minimum of 1 litre / 30oz per round — take a few sips every couple of holes
- Do not wait until you feel thirsty — by then you are already mildly dehydrated
Even mild dehydration is enough to affect concentration and decision making.
🏁 After The Round
Because golf is low intensity, recovery demands are not high, but it is still worth getting on top of things after your round.
- Rehydrate — get your fluid levels back up
- Consume some carbohydrates and protein to replenish and repair
- No need to overthink it — a normal balanced meal does the job
✅ The Simple Version
- Eat well the night before
- Have a proper breakfast before you play
- Snack on the course before hunger hits
- Drink water consistently — 1 to 2 litres per round
- Recover with food and fluids after
Golf is hard enough. Do not make it harder by being hungry and looking for food instead of focusing on your game.
