Push Your Limits
Nutrition for Performance
In collaboration with the Verde Nutrition Co.
Push Your Limits – Nutrition for Performance is an in-depth toolkit for successful implementation of nutritional strategies in your training and day-to-day lifestyle so you can continue to push your limits.
You’ll be guided through the foundations of nutrition, specific macronutrients and their role in performance, the go-to guide of household staples for meal prep, and finally how to tie it all together through creating nutritious and delicious meals.
You’ll also have access to five worksheets that address key topics and aspects of fuelling for performance, recovery and how to periodise your nutrition around training loads.
The following is a sample of what you can expect in Push Your Limits – Nutrition for Performance
What are the food groups?
There are 5 major food groups, which have been outlined in the diagram below taken from The Australian Guide to Healthy Eating. These food groups serve as a guide to what foods constitute each food group and also detail roughly how many serves of each group you need per day. These values are based on an average daily adult intake; therefore your health goals may require a slight change from these values, although they do serve as a great guide.
Yellow: carbohydrate and grain-based foods.
Blue: meat, fish, poultry, seafood, eggs.
Purple: dairy products
Green: fruit and vegetables.

Macronutrients & micronutrients
The food and drinks you consume on a day-to-day basis are made up of macronutrients and micronutrients. Macronutrients are nutrients that are needed in larger amounts and consist of carbohydrate, protein, fat and alcohol. These are the nutrients from which we derive energy in the form of kilojoules or calories, and each macronutrient carries a different amount of energy per gram.
Micronutrients do not have energy value and consist of the vitamins (such as the B group and fat-soluble vitamins), minerals (iron, calcium, zinc etc.) and antioxidants that help support many metabolic processes in our bodies. These are needed in smaller amounts.
Meeting the necessary requirements for macronutrients and micronutrients is essential for the overall functioning and recovery of our body, and depending on the fat loss goal there are certain manipulations of the macronutrient ranges that can assist you in getting you where you want to go.
Carbohydrate
Carbohydrate foods are your primary fuel source during high-intensity exercise and should be included on training days. Carbohydrate foods consist of wholegrain bread and cereals, rice and pasta, fruit and vegetables, and dairy products, and once digested they are broken down into sugars for you to burn.
When you eat carbohydrates, your body has enzymes that break them down into smaller sugars to be absorbed, and this causes a spike in a hormone called insulin. The rate at which these sugars are broken down to be absorbed is called the Glycaemic Index.
Carb foods that break down rapidly for absorption are high GI foods, such as white bread, honey and soft drinks, and those with a slower rate of breakdown are called low GI foods, such as wholegrain varieties of cereals and grains, apples and leafy green vegetables. Choosing wholegrain varieties increases your daily fibre intake and helps control the release of the sugars into the bloodstream leading to a steady energy flow throughout the day.
Protein
Protein foods should be consumed at all main meals and snacks, especially after a training session, given their role in contributing to feelings of fullness and supporting recovery.
Protein foods can either come from plant-based sources, including legumes, nuts and tofu, or from animal sources including meat, fish, poultry, dairy products and eggs. You should be aiming to consume approximately 20-40g protein at main meals and 10-30g for snacks (depending on body weight and activity levels), as this allows an effective distribution throughout the day to help curb those cravings when in an energy deficit.
Fat
Healthy fats, or unsaturated fats, have an important role in satiety, the absorption of fat-soluble vitamins and contain anti-inflammatory properties. Foods such as oily fish are great for including at least 2-3 times per week, and other additions such as avocado, nuts, seeds and olive oil are great for including as a thumb-sized serving at main meals. Although unsaturated fats carry many benefits, they do contain the highest amount of energy per gram, therefore adhering to the serving size helps to minimize excess energy intake during an energy deficit.
Alcohol
Although we would normally associate macronutrients with health, alcohol too yields an energy factor of which is important to address when speaking about fat loss. When alcohol is consumed, our body cannot store it therefore it is a priority to be metabolised as soon as possible. When large volumes of alcohol are consumed, this can impede the recovery process and also disrupt sleep patterns, which can catalyse a chain of consequences not ideal for fat loss.
Furthermore, alcohol disturbs the stimulation of hunger hormones. This makes it very easy to overindulge in high-energy nutrient-poor foods, consequently pushing you closer to, if not over to a positive energy balance favourable for weight gain. Avoiding alcohol will assist in reducing calories in, however in some social scenarios it is important to celebrate, so opting for sparkling water as a mixer over a soft drink or a glass of champagne over a cocktail can help keep calories in low.
Ergogenic Aids & Supplements
With respect to nutrition, an ergogenic aid or supplement is any nutritional substance that has the capacity to improve physical performance or recovery due to the concentrated and isolated nature of a specific substance. When considering any supplement, there are three questions you should ask:
Is it safe?
Is it legal?
Is it effective?
As evident in the pyramid above, supplements are the last thing to consider when it comes to your nutrition, as they’re there to supplement your nutritional and training plan, rather than be the plan. Furthermore, if a supplement or ergogenic aid is indicated, it is imperative to consult an Accredited Sports Dietitian to provide advice around use and guidelines. Purchasing something online from another country may be subject to different regulation rules, therefore if competing there may be an increased chance of inadvertent doping outcomes.

Always seek the advice of your GP or Allied Health Professional (AHP) before embarking on any exercise program.
Running training is strenuous and tough on your body. You should make sure that you are physically healthy, getting enough sleep, and eating a nutritious diet before you begin. If you are currently fighting injury, this is probably not the time to begin your running training journey.
