Essay question 2: Energy balance
A) My estimate energy requirement is 1805.25 kcal per day. Compared this to my average actual calorie intake for the three days (1773 kcal), I am at negative energy balance. I am consuming -32.25 kcal fewer than my estimated kilocalorie expenditure.
B) Evaluate your BMI. Is it above, within, or below the recommended healthy weight-for-height range of 18.5 to 24.9?
My BMI is 18.94 kg/m2, which is within the recommended healthy weight-for height range.
C) If my energy balance were to remain as it was on the 3 days that I kept the diet intake record for one year, which is 32.25 kcals less than I needed to maintain energy balance every day. I would consume 11,771.25 kcals (32.25 kcals x 365 days) less than my needs over a period of one year. Thus, I can expect a weight loss of around 3.4 lbs (11,771.25 kcal deficit/3,500 kcal/lb) at the end of one year.
D) Personally, I think the weight loss that I have calculated in section C will not occur since the energy deficit average is solely based on three day’s data. My eating pattern may be different over a year time and my diet record for three days is not representable enough. Normally, I would eat more during winter time to keep myself warm. With my always changing diet pattern, my calories consumed will probably be different, which means I may not be in negative energy balance for one-year time. Besides, the daily requirement calculated is just an estimate. This mean my actual daily requirement maybe different from the estimated energy requirement. In addition, the estimated energy requirement is based on weight, height and activity level. Considering physical activity level always changes over time and also basal metabolic rate are also affecte...

...d to inaccuracy in the energy balance calculation. Also, I may overestimate the energy requirement by neglecting the factors including restricted calorie intake, less body surface area and muscle mass can decrease the basal metabolic rate.
Apart from basal metabolic rate and energy balance calculation, environment also play a role in the accuracy of my diet analysis. Since this is my first semester here in Minnesota, the change in environment and unavailability of my home town food have a huge influence on what I eat, this may not reflect my real eating pattern. Also, the busy university lifestyle has also change my way of eating. Besides, the portion size I record may not be exactly the same as what I had eaten, since it was just an estimation. I did not use an electric balance to weigh the food before I ate. Thus, my energy intake is very likely to be inaccurate.
8 of the 13 participants had their food strictly restricted. They were given an hour to eat and the different restriction levels were measured.
For this part of assignment, I kept record of two consecutive days of what I ate for that days and how much calories I got from that food and drinks. Every day I usually start routine with drinking water which I think is the most important thing for a healthy lifestyle. Apart from this, I learned some following main points to help me by comparing my food chart with the recommendations
Energy content is an important property of food. The energy your body needs for running, talking, and thinking comes from the food you eat. For this project I conducted an experiment on different kinds of nuts in which I aimed to determine how much energy were stored in these nuts. The experiment was executed by burning these nuts to heat up a container of water and calculating the change in temperature that takes place. Using the change in temperature, one could calculate the amount of energy set free by the burning nuts.
Nearly two-thirds of the United States population is overweight. There are several ways to determine if a person is obese or overweight. Experts say that a person’s body mass index is the best way to determine an adults weight in relation to their height. A BMI from 18.5 to 24.9 kg/m2 is considered normal, adults with a BMI of 25 to 29.9 kg/m2 are considered overweight. There are exceptions with peoples BMI, an athlete can have a high BMI and not be overweight or obese. Adults with a BMI of 30 kg/m2 or higher are considered obese. A person with a high BMI can have a normal amount of body fat if they have more muscle tissue. However, the risk of death and disease is increased for adults who are overweight and obese (Kolata 1)
...r height in metres, a healthy BMI for an adult is 18.5 to 25 and if you are classed as obese, your BMI is 30 or more. (Astrup 2009)
I’m not getting what I used to, so I’m going to slow down to conserve energy.” BOOM! Your metabolism drops and your body begins using less energy and requiring less energy. But then you start to eat like a normal person and your body doesn’t realize that it should metabolize those calories faster. It’s too worried that the food will stop, like it did when you were dieting.
Reduced physical activity represents one of the most significant changes in lifestyle that has been observed during the twentieth century. Our sedentary lifestyle and the reduced energy requirements of the majority of our jobs has been a source of comfort in a business world where efficiency and productivity are sought. The impact of the transition from a traditional to a modern lifestyle on daily energy needs can be estimated by various means. By using the doubly labeled water technique and indirect calorimetry, Singh et al. (1) showed that the energy cost of living at the peak labor season was as high as 2.35_resting metabolic rate (RMR) in Gambian women. When this value is compared to results usually obtained in women living in industrialized countries, 1.4 to 1.8_RMR (2,3), it can be estimated that f...

My overall Kcal average for the three days I recorded was 4,318, while my Daily recommended intake was 3,484. In terms of Kcal, I am eating more calories per day than recommended. Breaking it down a bit farther to percent of carbohydrates, I ate 110 percent of my Daily Required Intake for Carbohydrates, specifically 39.1 g more than recommended. The daily recommendation for protein is ten to thirty-five percent,
This diet critique will be from everything I ate from Sunday, February 7 to Saturday, February 13. According to my dietary reference intake (DRI), I was allowed 2191 kcal for the week and I consumed 1978kcal. I met 90.3% of what I am allowed, although it Is on the higher end of the range it is still within. My calories from fat were 647kcal and my max allowed is 767kcal. Although I did not go over the minimum I was allowed was 438kcal so I still went over 209kcal from fat in which could be avoided. Checking the fat content on my snacks and limiting myself could reduce my actual intake while still being in range. The same applies to my total fat intake. My max was 85g and I consumed 72g when the lowest could have been 49g.this is still 23g of fat consumed that I did not not. Especially for trans fat I consumed 3.2g when ideally it should be 0g. Eliminated trans fat as a whole because there is no nutritional benefit would eliminate this entirely from my diet. My omega 6 and omega 3 intakes did not meet my DRI. I consumed only 3.9 g or omega 6 when my DRI is 12g and I consumed 0.5g of omega 3 when my DRI was 1.1g. To increase my omega 6 intake, I could start using grapeseed oil instead of the cheapest one I find which may not be the healthiest. I already use purchase grapeseed oil for my hair so getting another bottle to cook with would be easy. To increase my omega 3 intake, I could start consuming more beef and salmon in my diet, the majority of the meat I eat in my diet is chicken, so this switch could add variety.
My diet during this time consisted of carbs only in the morning and none throughout the remainder of the day for the most part. The morning carbs were my saving grace as they produced a noticeable energy spike that allowed me to get my days started. The down side to this is that due to the carbohydrate deficit, my body quickly burned through them before lunch time every day. At a 650 calorie per day diet, I was able to lose about three percent body fat but at the sacrifice to strength and endurance throught my workouts. Standing up became a chore and at times took my breath away.
The proportion of my total Calories target is 2200 Calories, but my average is 1381 Calories which is under the required intake. Protein’s is 46g, my average consumption is 45g which is one gram lower from my target. Carbohydrates on the other hand shows satisfactory with target of 130g which is 45-65% in Calories percentage, my average consumption is 173g, which is 50% Calories. My Total Fats target 20 – 35% of total Calories, my average consumption is 41% which is over the required consumption. Lower calories will give me less energy but if I lower my fats intake, I will hopefully lose weight. I will have to lower my fats intake by eating less of barbecued and fried pork, beef and chicken, instead, I will try to eat more baked skinless chicken and consume more of whole oatmeal or less white
There are different ways to determine your body composition and the risks that they involve. In this lab, body measurements are taken to find the body percent fat, waist-to-hip ratio, body mass index (BMI), and basal metabolic rate (BMR). Skin folds for the chest, abdomen, and thigh were taken for males, and triceps, iliac crest, and thigh for females. Age, height, and weight for each person were recorded as well as the waist and hip circumference.
Patient is a female, aged 65 years old who requires weight loss as GP referral reported. In order to assess her, anthropometric measurements were taken. She has a current weight of 135.5kg and her height is 1.55m.Consequently, she has a body mass index (BMI) of 56.4kg/m² and she is obese class II. According to her biochemical results all parameters are normal except raised glucose and TG. Clinical data obtained include her current, past medical history and medication. She is type 2 diabetic and obese. She has a past medical history of hypertension, hyperlipidemia and sleep apnoea. The medications she takes are glucophage for controlling blood sugar levels and salmeterol for treatment of asthma. Diet history of patient was taken by asking her recall the last 24 hours food and drink intake. Her estimated energy intake is about 2445kcal from which 44.3% from fat and 67g protein. Patient energy requirements calculated from Henry were (BMR) = (8.52W+421H+10.7)*PAL (1.4) =2022kcal/d. Total estimated energy requirements were 2022kcal per day. Protein requirements based on 75% of actual body weight was 101.6g protein per day. Total fluids requirements estimated using 25ml/kg adjusted body weight and is about 2293ml per day. Environmental data include that lives with her family and she does not exercise.
