The Low
Carbohydrate Diet
What is a Low Carbohydrate Diet?
The Low Carbohydrate Diet limits foods high in starches and sugar, while placing a greater emphasis on foods high in fat and protein as the main energy sources. The potential impact on reducing insulin for improved weight loss outcomes and reduced risk for cardiovascular disease has seen the Low Carbohydrate Diet skyrocket in popularity.
This diet limits carbohydrate intake to around 130g per day, which should not be mistaken with a Ketogenic diet that limits carbohydrates to less than 60g per day. A low carbohydrate diet will not place you into a state of ketosis, however, it is an excellent way of eating to manage blood glucose and energy levels.
The low carbohydrate diet may improve the management of blood glucose levels to reduce the risk of type 2 diabetes, protect against hypertension, obesity, elevated cholesterol or triglycerides and Metabolic Syndrome. Those who have genetically impaired carbohydrate metabolism may benefit greatly from a low carbohydrate diet for health improvement and/or weight loss.
Macronutrient Breakdown
Macronutrients are our energy sources derived from food that can be categorised into fat, protein and carbohydrates. Not all macronutrients are created equal, so it is important that you source your macronutrients from healthy foods to best achieve the results that you are after.
Calculating Your Daily Energy Intake & Macros
-
Calculate your daily energy requirements using the calculator link above. Expand the settings on the calculator and select 'kilojoules'.
-
Once you have your 'mild weight loss' or 'weight loss' kilojoule requirements, you'll need to calculate your daily macronutrients in grams.
We will use a daily energy requirement of 7,524kJ as an example:
Macronutrient
% Daily Energy
Daily Intake (g)
Carbohydrates
1g carbs = 16.7kJ
25%
40%
35%
1,881kJ
= 112g carbs daily
Fats
1g fats = 37.7kJ
Protein
1g protein = 16.7kJ
3,009kJ
= 79g fats daily
2,633kJ
= 157g protein daily
You can track your daily macronutrients by entering your daily diet into the Easy Diet Diary App (linked below)
Low Carb Diet Guidelines
-
1/2 cup (39g) uncooked rolled oats - 21g carbs 175g cooked brown rice - 56g carbs= 27g carbs
-
2 regular slices wholemeal bread - 25g carbs
-
1 medium boiled potato
REFINED CARBOHYDRATES
-
Avoid refined sugars, natural sugars and carbohydrates which are lower in fibre and many forms are generally made from white flour (which are also very low in nutritional value).
-
Refined carbohydrate sources include: white rice, white bread, pizza bases, pastries, cakes, pies, donuts, biscuits, chocolate, lollies, soft drinks, sweetened beverages and other sweet foods.
UNREFINED CARBOHYDRATES
These foods are generally higher in fibre and less processed with more nutrients.
-
Unrefined grains include: rolled oats, brown rice, wholemeal bread, quinoa, buckwheat, spelt and wholemeal pasta.
-
Starchy vegetables include white potato with skin (cooked and cooled for lower GI), sweet potato, pumpkin, corn, peas, beetroot and carrot. These vegetables are higher in carbohydrates and need to be limited on a low carbohydrate diet.
-
Fruits are high in fibre and some fruits are lower in sugar (carbohydrates), such as berries, sour cherries, green apples, lemon, lime, plums and grapefruit. Other fruits that are higher in sugar such as grapes, bananas, mangoes, oranges, sweet cherries, pears and kiwifruit may still be consumed in limited quantities (eg. 1 serve daily).
-
Legumes are high fibre, protein rich plant foods with a high starch content that may need to be limited. These include chickpeas, lentils, beans and split peas.
-
Dairy products like milk, cheese, yoghurt, kefir or butter contain carbohydrates (in the form of lactose, a sugar) which may need to be limited. Some low fat dairy products are often higher in sugar and may need to be limited. TIP: look for less than 2.5g of sugar per 100ml, or less than 5g sugar per 100g on a nutrition panel for low sugar food products.
-
Non-starchy vegetables: these foods should provide the main source of carbohydrates in a low carbohydrate diet and include: leafy greens, broccoli, cabbage, brussel sprouts, cauliflower, capsicum, zucchini, eggplant, cucumber, tomato, onion, garlic and mushrooms.
-
Fibre: focus on high fibre foods such as non-starchy vegetables (especially broccoli, cauliflower and brussel sprouts), avocado, nuts, seeds and fibre boosters such as psyllium husk or LSA added to food. Aim for 25-30g fibre daily.
-
Hydration: avoid high sugar drinks (including fruit juice) and include 8 glasses of filtered water per day. Sip on sugar-free herbal teas and low carbohydrate soups to boost fluid intake.
