Summary: Subtract ~16g of Carbohydrate from your set carbohydrate intakes and 7.2g of fat from you set daily fat requirements to allow for your alcoholic beverage. Using the same alcoholic drink (130 calories) using 50% calories from carbohydrates and 50% calories from fats.Ħ5 calories (alcoholic drink) / 9 calories (energy in 1 g of fat)Ħ5 calories (alcoholic drink) / 4 calories ( energy in 1g carbohydrate) Substituting from both macronutrients may mean you have to do a little more math, but for me personally, I will use a combination of both depending what macronutrients I have left. For example, if your daily fat intake was only 50g and you substituted in your alcoholic beverage entirely from fats, your food choices for that day would be highly restrictive in order to keep within your daily fat targets.
Ideally you would substitute both carbohydrate and fats, as this gives you more flexibility with your food choices. Substituting from both carbohydrate and fat
Knowing this information means we can substitute macronutrients, and the most obvious choice is carbohydrate, since there isn’t a need, unlike the need for protein or fat.
In extreme circumstances like starvation, our brain is also able to regulate using ketones as a fuel source. However, even if we choose to consume zero carbohydrates, or if we are in a state of starvation, we are still able to produce glucose for essential tasks through a process known as gluconeogenesis, using other metabolites such as amino acids and by products of fatty acid metabolism. We also have a requirement for fats for specific functions within the body. Our bodies primary energy source is glucose. How we factor in alcohol is actually very simple. Here it can be eliminated via the urine or used for energy production in the TCA cycle (1,2). It is then further metabolised to a less active by product called acetic acid. Once consumed, alcohol is first oxidised to acetaldehyde, a toxic substance and known carcinogen. ~50% of East Asians possess only one, the cytosolic isoform, which is why there is a higher frequency of alcohol intoxication amongst East Asians. Caucasians have two major liver isoforms of ADH and ALDH, cytosolic and mitochondrial, both isoforms assist in the breakdown and elimination of alcohol. The most common of these pathways involves two hepatic enzymes, namely alcohol dehydrogenase (ADH), and aldehyde dehydrogenase (ALDH). Alcohol sits in between with 7 calories or 29 kilojoules per gram consumed.Īlcohol (ethanol) is metabolised by several processes or pathways. Protein and carbohydrates both contain ~4 calories or 16 kilojoules per gram, while fat contains almost double at 9 calories / 37 kilojoules. The remaining calories can come form either carbohydrate or fats, whichever is your preference.Įnergy values of Protein, Carbohydrate, Fats and Alcohol Typically, I like to use 2.0-2.5g of protein per kg of lean muscle. By including a wide variety of fresh nutrient rich foods enables us to meet our micronutrient and fibre requirements. Something else that is frequently overlooked is our daily micronutrient and dietary fibre intakes. Knowing your total calorie requirements is a key determinant for fat loss, however if we want to maintain a lean muscular physique, there are optimal amounts of protein, fats and carbohydrates we need to consume, to achieve this. Instead, this will help you to expend calories and help create a caloric deficit. Running steady state or walking for 30 mins every day isn’t going to help you build muscle. The second way we can create a caloric deficit is by increasing energy expenditure and being more active, and we know that if you are looking for a leaner more muscular appearance, then weight training is optimal. For fat loss to occur, your caloric intakes need to be set below your predicted EER. This is known as your maintenance calories, or your estimated energy requirements, and is often abbreviated as EER. Creating a caloric deficitįirst you need to be able to determine what calories you require in order to maintain your current weight and body composition. Remembering that in order to lose body fat, we must first create a caloric deficit, and there are a number of ways to do this, either by manipulating your nutritional intakes or training volumes. There are 4 key macronutrients, the three we discuss frequently are protein, carbohydrate and fat, but alcohol is the 4th macronutrient, and all of these provide us with energy.
