Stress and Weight Gain
Stress and Weight Gain

Weight gain is a result of your calorie intake being higher than your calorie expenditure creating a surplus of energy as a result (1), and often stress would not be the first issue to consider when weight gain has become problematic. However, stress can interfere with normal regulation of how our bodies break down food and its transformation into energy...

Protein

  Structure and Function Proteins are large molecules comprising amino acids (AAs) linked together by peptide bonds, and thus serve as the ‘building blocks’ of proteins (1). A protein generally contains differing amounts of a total of 20 individual AAs (2), consisting of 9 essential AAs (EAAs) and 11 non-essential AAs (NEAAs)(1). EAAs must be consumed via dietary means since...

Fat

  What is Fat and How Much Do I Need? Fat is a macronutrient which provides energy, allowing the body to function through daily tasks and activities. Each gram of fat provides the body with 9 kilocalories (kcal) per gram, making it the most energy-dense macronutrient. The recommended overall fat intake for a UK healthy adult is between 20-30% of...

Protein has many functions but in general terms it is responsible for the growth and repair of cells and structures in the body. Protein, like carbohydrate provides 4 kilocalories (kcal) per gram consumed. Protein Requirements The amount of protein an...

Alcohol

  Nutritional analysis (i.e. Energy/Calories) In UK adults (aged 19-64), alcohol has been shown to typically contribute roughly 10% of total energy intake (1). According to Drinkaware, those of us (4 of 10) who consume alcohol are not aware of alcohol calories and their food equivalents, but, since alcohol is produced through the fermentation of sugars (e.g glucose, fructose, and...

Carbohydrate

  Carbohydrate is one of the three macronutrients that comprise our diet, protein and fat being the remaining two. Carbohydrates are categorised by their chemistry but there are three types present in food: sugar, starch and fibre. Carbohydrates are important for health, providing energy and prevention against potential diseases. Like protein, carbohydrates provide four kilocalories (kcal) of energy per gram...
