Working out? What to eat, when to eat and why

It might be fashionable to exclude carbohydrates from your diet, but it is not necessarily the healthiest approach to eating – especially if you are also working out

Jon Denoris, a UK-based performance coach, talks of ‘nutrient timing’: eating the right food at the right time 
of day.

Can you pronounce the ingredients?

‘Eat unprocessed, whole foods as often as possible,’ says Jon. ‘If your diet is rich in high-quality meat and fish; essential fats such as avocados, nuts and coconut oil; whole foods such as brown rice and quinoa – which have a lower GI rating than white pasta or white boiled rice – and lots of vegetables, then you are already eating healthily. If your food has a label, however, then be wary. If you can’t pronounce the ingredients, don’t eat it.’

Eat protein

‘Protein such as meat, fish or eggs should satisfy your appetite and regulate your metabolism. You should find you have fewer cravings for junk food, too,’ says Jon. You could add chicken or eggs to a salad, or drink a shot of whey protein with your meal.

Stick at it

A common mistake is to ditch your healthy eating plan before you see the results. Jon recommends persuading others to join you – or at least surrounding yourself with supportive people. You should also only start a regime when your life feels relatively stable.

‘Flex’ your carbohydrates

Carb flexing means eating more good carbohydrates, such as green and root vegetables, at the right time of the day. You should eat a bit more carbohydrate earlier in the day to give you more time to convert it into energy. ‘Eating carbohydrates in the morning and consuming just over half your calories by the end of lunch helps the body use fuel more efficiently so that it isn’t stored as fat,’ says Jon.

Second, eat any starchy carbohydrates such as potatoes and rice after you have done some exercise. ‘This will give your muscles energy when they need it most,’ says Jon. ‘It will also help recovery and reduce insulin spikes, as well as making it easier for your body to absorb protein.’ Eat fewer starchy carbohydrates in the evening, opting instead for high-protein food and good fats, particularly if your goal is weight loss rather than just better performance.

Cheat meals

Jon says: ‘If you are being otherwise disciplined about your diet, it’s good to have the occasional cheat meal. 
Aim for 80-90 per cent adherence each week.’ 
There are ways to make cheat meals healthier, too. 
‘Try to eat protein in your cheat meal,’ says Jon, ‘and if you are going to eat carbohydrate such as pizza or pasta, train immediately before, so that your body can use the extra fuel.’

The 45-minute window

‘For about 45 minutes after exercise, your muscles are ‘open’ like gates,’ says Jon. ‘They don’t completely close after that, but the rate at which they absorb nutrients diminishes.’ Those who are serious about training, should consider drinking a protein shake and eating a small amount of carbs after they work out. Protein shakes take about 30 minutes to reach the muscles after ingestion.

Endurance events

exercise

Often people think that if you are training for an endurance event, you should eat carbohydrates before, during and after you exercise. This is not necessarily the case. ‘If you train at low to medium intensity, you should eat balanced meals composed of 30 per cent protein,’ says Jon. ‘If you train at high intensity, you should eat more nut butters, sweet potatoes, date and walnut cake, fruit smoothies and blueberries.’ There is no need for more carbohydrates or sugary drinks in either case.

Food to help you sleep

‘Eating certain foods at night helps promote sleep,’ says Jon. ‘Turkey, salmon, cottage cheese, nut butters, bananas and Montmorency cherries all contain tryptophan, an amino acid that converts to melatonin. Almonds are also good as they contain magnesium, which relaxes the muscles.’

Rest days

On days when you are not doing any exercise, you should replace carbohydrates with good fats such as avocado, seeds and nuts. Jon says: ‘When you’re training, carbohydrate is more likely to be used up by your muscles, but when you are resting, it is more likely to be laid down as fat.’

What to eat when

8am-10am

Eating carbohydrates earlier in the day will give your body more time to convert them into energy.

1-2pm

You should have eaten 55 per cent of your carbohydrates by now. Eat more protein by adding chicken or eggs to a salad or drinking a shot of whey protein.

45 minutes after exercise

Drink a protein shake and eat a small amount of carbohydrates. Your muscles will be more ‘open’ during this window to consuming fuel and absorbing nutrients.

7-9pm

Eating turkey, salmon, cottage cheese, nut butters, almonds, bananas and Montmorency cherries will help you sleep. Avoid starchy carbohydrates such as potatoes and rice, if you are trying to lose weight.
