Energy expenditure, intake and balance - 1852 Words

Task 1 [P3, M1] Describe/explain potential sources of energy intake and expenditure and the factors that affect intake and expenditure such as basal metabolism, age, gender, climate and physical activity. Food is a source of energy intake as it contains carbohydrates; there main function is to store energy in the muscles. Carbs are a macronutrient and come in two different forms, simple which are foods like chocolate and sweets these release energy quickly, the other form is complex which are foods like pasta and rice they release energy slower so are better to keep energy for a sustained period of time. There are certain factors that affect energy intake for instance what gender you are affects how much energy you need, a male’s†¦show more content†¦These measurements are then converted into body fat percentage using an equation; a male should have around 15% body fat whereas a female should have 20-25% due to them having breasts etc. (100 words) Bioelectrical Impedance- Bioelectrical impedance measures the resistance of body tissues to the flow of a small electrical signal. The proportion of body fat can be calculated due to the current flowing through the parts of the body that are made up of mostly of water such as blood, urine and muscle this is not possible through bone, fat and air. By doing this it is possible to work out how much body fat the person has by combining the bioelectric impendence measurement with factors such as gender, age, height, weight, and fitness level. (100 words) Hydro densitometry- Hydro densitometry (which is also known as hydrostatic weighing) is weighing someone while they are in water, it is considered to be the most accurate form of measuring body fat. A very large tank of water is used for this test, firstly a comparison is made between the underwater weight and the dry weight of a person. Due to fat being less dense than the other tissues in the body, it floats more easily. The more fat a person has on their body, the greater the difference between the dry and wet weights. While this method of measuring is very accurate and considered the best way of measuring body fat, not many people use this method because the equipment and test is highly expensive.

If energy intake is greater than energy expenditure, weight gain will occur. In contrast, energy expenditure in excess of energy intake will result in weight loss ( Dietz Gortmaker, 2001). However, Obesity is a complex disease that involves interactions between genetics, regulation of energy balance, and strong environmental influences such as increased caloric intake and decreased physical activityRead MoreActivity Related Energy Expenditure, Apetite and Energy Intake1038 Words   |  4 PagesResult Subject data Table 1 Individual daily energy expenditure and energy intake EI (KJ) EE(KJ) Day 1 2385 3400 Day 2 4184 5000 Mean 3284 4200 SD 1272 1131 Figure 1 Mean percentage of energy intake as protein , fats and carbohydrates with percentage.

FIGURE 11 REGRESSION VARIABLE PLOT OF ENERGY EXPENDITURE CHANGE AND FAT LOSS The correlation coefficient for this test was 0.218 and the p-value was 0.318. This proves the null hypothesis that there is no statistically significant correlation between the rate of fat lost and the change in Total Energy Expenditure from Baseline to Follow-Up. The average TEE: BMR ratios increases from 1.10 pre-opRead MoreHow Energy Balance Affects Weight Essay957 Words   |  4 PagesHow energy balance affects weight and if there is in fact a way, or ways, to â€Å"increase† metabolism? Our body is consisted to be in energy balance when energy intake equals energy expenditure and body weight and composition are maintained. When there is an energy imbalance, â€Å"the rate of change of energy stores equals rate of energy intake minus rate of energy expenditure† (Galgani Ravussin, 2008, p. 110). Weight gain occurs when our body is in positive energy balance, and weight loss occurs whenRead MoreDescribe The Structure And Function Of The Digestive System970 Words   |  4 Pagesassociated with nutrition Nutrition macronutrients †¢ carbohydrates, †¢ proteins, †¢ fats Nutrition micronutrients †¢ vitamins, †¢ fibre Research and define nutritional requirements †¢ Recommended Daily Allowance, RDA †¢ Optimum Level, OL †¢ Safe Intake, SI †¢ Estimated Average Requirements, EAR To achieve P1: Write a report or essay that describes nutrition.

The presence of compensatory adjustments in response to exercise has been shown over 35 years ago [21]. Particularly, behavioral adjustments in non-exercise PA and energy intake have been considered key contributors to the limited success in exercise-based weight-loss interventions (Figure 1) but there is also evidence on inter-individual differences in metabolic adaptations. In order to strengthen the efficacy of exerciseRead MoreEssay on Weight Management1269 Words   |  6 Pagesbehavior modification, dietary principles, energy balance components, and a sound food plan. In order to create a behavior modification plan that will be successful for the individual, identifying cues, responses and consequences of eating behaviors is necessary. Control of eating behavior, physical activity, emotional, social, and psychological health must all be analyzed and interventions applied. Behaviors related to problems with intake and expenditure of energy must be specifically defined.

Before a person can have a diet that meets their needs for weight maintenance or weight lost, they have to first understand their nutritional needs. Deity plus was used to track my food intake from Sunday February 26 through Thursday March 2.

The concept of energy intake and expenditure refers to the amount of calories per day that an individual consumes, and is the chemical energy in foods which can be metabolized to produce energy available to the body. As stated before energy is obtained from the foods we eat and is used to support an individual’s Basal Metabolic Rate, energy is measured in calories or joules as both units areRead MoreCauses Of Obesity In Western Countries1251 Words   |  6 Pagesdeveloping. Consequently, prenatal rats are highly prone to adverse effects of EDCs on the development of the brain and its ability to properly integrate peripheral signals conveying information about meal processing, gastrointestinal activity and energy stores.

These findings explain in part why higher level of obesity is seen in countries where obesogen exposure is not uncommon
