What are macronutrients and their sources

What are macronutrients? Macronutrients are nutrients that are required by the body in large amounts. Macronutrients are the building blocks for many other components needed by the body for good health. Each macronutrient also contributes to dietary energy intake. There are three essential macronutrients; carbohydrates, protein, and fat. Alcohol is the fourth macronutrient. It is… Read More What are macronutrients and their sources

Weight loss restriction versus weight loss adherence

Weight loss restriction versus weight loss adherence. The larger the energy restriction, the harder it is to adhere to the energy restriction. REDs are the easiest restricted diet to adhere to as they have the least energy restriction. VLEDs are the hardest to adhere to because of their large energy restriction. Weight loss is greater following a VLED and smaller following… Read More Weight loss restriction versus weight loss adherence

What are fasting diets?

Fasting Diets Description: Intermittent fasting diets are a relatively recent area of research. They are an example of a “combination” energy restriction. It is recommended that people follow a VLED anywhere from one to three days a week, except the energy comes from food rather than formulated meal replacement products. The other days, people choose… Read More What are fasting diets?

What is very low energy diets (VLEDs)?

A very low energy diet (VLEDs) has a very low total daily energy intake target. On this diet, people are guided to consume between 2500–4000kJ per day. Formulated Meal Replacements This is usually achieved using Formulated Meal Replacements (FMRs) which are designed to be a nutritionally complete replacement for all meals in a day when consumed as directed. They are… Read More What is very low energy diets (VLEDs)?

What is Low energy diets (LEDs)?

Low energy diets (LEDs) use daily energy intake targets between 4200–7000kJ. This usually involves following a ‘prescribed’ diet plan such as those found on web-based programs or home delivered, pre-prepared meals. LEDs usually result in low to moderate adherence but can take the hassle out of planning and cooking meals. A nutrition breakdown of this intake:  Energy (kilojoules)Protein (g)Fat (g)Carbohydrates (g) Pre-portioned Just Right,… Read More What is Low energy diets (LEDs)?

What is Reduced Energy Diets (REDs)?

Reduced energy diets (REDs) identify ways within a person’s current eating habits to reduce 2000 to 4000 kJ from their usual energy intake each day. Usual energy intake is the amount of energy you usually consume, although this can vary from day-to-day. They usually involve swapping energy dense foods for low energy density foods and managing portion sizes. For example,… Read More What is Reduced Energy Diets (REDs)?

What is energy restricted diets and kilojoule restriction?

Energy Restricted Diets There are many approaches to kilojoule restriction for weight loss or to prevent weight gain. Kilojoule restriction is achieved by making changes to someone’s usual daily food intake. Some changes are easier to stick with but result in slower weight loss, whereas others are more difficult to stick with but provide more rapid weight loss. The video below explains… Read More What is energy restricted diets and kilojoule restriction?

Energy density: Energy content per gram of each macronutrient

The total kJ content of a food item depends on the proportion of macronutrients (carbohydrate, fat, protein, and alcohol) present in the food and the serving or portion size. Alcohol is not needed by the body and can contribute large amounts of energy to a person’s daily intake. When we compare the amount of kJs between foods… Read More Energy density: Energy content per gram of each macronutrient
