You are... bread?

My sister...?
You are what you eat my mother always says! And so does my sister come to think of it... does that mean my sister is this?

I certainly hope not, because that would be kind of creepy. Humans aren't meant to be made of vegetables... eat them? Sure. Be them? No.

This week I have to write a summary of an article done on my blog topic, which is healthy weight.

The article is Here. It is an article on the effects of beverages on children, and we are specifically looking at sugary beverages, such as fruit juices and sweetened fruit drinks.

The aim of the study was to pinpoint if there was a link between the consumption of such beverages and its effects on weight status, IE obesity. The sample for this particular study was gathered through the National Health and Nutrition Examination Survey (1999-2002), and targeted preschool children specifically.

There were four elements to the study. First was the element of parent reported demographic descriptors - Eg, the ethnicity of the child, physical activity level, age, income of the family, etc. Secondly, there was a 24 hour dietary recall, with a trained interviewer getting the parent and child to reflect the foods and drinks consumed by the child that previous day. Thirdly, there was a physical fitness test of sorts, though simple for younger children. Finally, there was a standardized physical examination by a doctor.

100% fruit juice drinks were considered to only be so if they had no sweeteners, fruit drinks were any sweetened fruit juice, a drink flavored with fruit, or drink that contained fruit juice in part. Milk drinks were drinks that contained dairy, and was sub categorized further by percentage of milk fat. Any sweetened soft drink was classified as soda. Diet drinks were any of the above that were sweetened using a low calorie sweetener. Water was not included in this study. The amounts were reported in ounces to make the study easier.

The limits used for underweight were less than 5% BMI, normal weight was 5%-85%, risk of overweight was 85-95%, and overweight was greater than 95%. There were so few underweight, that their numbers were rolled into the 'normal' category.

There were 1572 children between the ages of 2 to 5, and were therefore included in the study. However, many of these had missing data, and were removed from the data set. The final number was 1160 children. 49.9% were male, while 50.1% were female. 35% were Caucasian, 28.3% were black, and 36.7% were Hispanic.

The findings were as follows:

24% of the children were overweight or at risk for being overweight. (OUCH thats a lot)
10.7% were overweight.
Overweight children tended to be older.
83% of children drank milk. (I personally hate the stuff)
48% drank 100% fruit juice.
44% drank fruit drinks.
39% drank soda (SO BAD)
The average child consumed 26.93 oz. per day, with 12.32 oz being milk, 4.7 oz of 100% fruit juice, 4.98 oz of fruit drinks, and 3.25 oz of soda.

HOWEVER - there was no conclusive statistically relevant finding that the drink that one consumed in the day affected your BMI. All that was affected was ones energy intake for the day, which would increase, but the body could adjust to those increased levels, and those levels would have to be maintained extensively to cause a change to BMI.

That's all for now!

Bodies and Masses and Index, Oh my!

So this week for my class, I was supposed to write about a controversy in my field - in my case, my field is healthy weight.

So, I have chosen to write about BMI and BFP!

BMI stands for Body Mass Index, BFP stands for Body Fat Percentage.

The two sides to the controversy are this:

Side A: The idea that BMI can be used as an effective tool for non-medical personnel to understand something about their weight, and if it is at a healthy place or not;

Side B: BMI is simply a diagnostic tool for medical personnel, and reflects little in terms of an individuals healthy weight., while BFP (Body Fat Percentage) is a significantly better and more realistic indicator of healthy weight.

So lets start with a quick background of both of these ways to measure the weight and height in comparison to each other. Where did they come from? Who invented them? How are they calculated?

BMI

Ancel Keys on the cover of Time
            Originally invented in the 19th century, called the Quetelet Index, it was relatively unused for very many years. However, in 1972 in the Journal of Chronic Diseases, Ancel Keys published an article called "Indices of Relative Weight and Obesity". In this article, he explored the different ways that body weight and height could be related to each other, and thereby confer some information to the doctor and/or the the patient. In exploring these relationships, he found that the ponderal index (height directly related to mass) is actually a fairly poor way to measure the healthy weight of an individual. However, according to Keys, the BMI (weight to height squared) is in fact the best indicator of healthy weight of those studied. (Keys)

There is a very important key word in that last sentence - that it was the best of those studied. As a debater, I have a tendency to see things like pretty easily. The medical community however, did not see that caveat. The result was that the BMI was utilized and became widespread through medical professionals.

This guy would probably be 'obese'
            The problem with BMI is essentially this - BMI utilizes averages of height and weight to determine if someone is on a healthy weight or an unhealthy. However, if someone is extremely muscular or very thin and wiry, they can often come in above or below their expected BMI, and in theory can therefore be termed 'obese' or 'underweight'. Quite obviously, this become problematic for athletes such as gymnasts, or people who are built rather heavy, but mostly of muscle. (Organization)

The biggest issue with BMI is that deals with averages based on populace, and doesn't make any kind of measurement of fat on the body, simply based on weight in relation to height.

It is also important to note that because of the average based importance of this type of study, it is good to be used as a population study, but not to be used for individual study.

BFP


It is unclear as to whom discovered how to calculate body fat percentage initially, however it is clear that there are very many ways to do it. From underwater weighing, to measurement with calipers, BFP gives a direct understanding of how much fat the individual has on their body, calculated as so:
Measuring Calipers

            Body Fat Percentage = (495/Body Density)-450 (Sports)

As you can see, it is body density that needs to be measured here, and that is what is measured through these various techniques.

General Body-fat Percentage Categories
Table of measurements relative to men and women

For men, your goal is between 2-24% body fat, which ranges from athlete to average BFP, while women aim for between 10-31% BFP, with the same scale. The reason for the difference is that men physiologically have more muscle and less fat than women, and as a result have lower indexes to worry about. (Muth)





Conclusion


To me, it is very clear. While BMI gives an excellent understanding of where you are in relation to other people, it gives a very small understanding of your own personal health. BFP gives an explicit number in terms of how much fat the individual has in their body, relative to the rest of their mass, regardless of their height.

SIDE B WINS!!

Work-In Plan

Why hello everyone!

I recently got a request from a reader to post my workout plan!

Now what I want people to keep in mind is that I am trying to lose weight but in a healthy way. This means I am not trying to gain muscle mass, but work on burning fat. As a result I am not doing any weight lifting or muscle building.

So I say work-in, not workout. Why is that Greg?

The reason is because I hate the term workout. Over time, I have grown to hate the idea of workouts. I have taken the out to mean taking time out of the things I enjoy. This has been one of the primary reasons I have chosen to not workout in the past.

The difference between a work-out and a work-in is that a workout is an arduous task that takes a bunch of time from your day, and isn't fun or exciting. A work-in on the other hand, is something you look forward to, something that is enjoyable. The key is finding a task that is actually enjoyable for you!

This summer I was more fit than I have been in a long time. I was sprinting, doing chin ups, but the most important thing I was doing was boxing.

All I had was a punching bag in my backyard, but as I'm sure you can imagine, I'm pretty big (that's the 6"4' coming into play). My punch is powerful. My 100 pound bag was just enough of a challenge for me to hit it and move it, but only by exerting myself.

It was fun! It was something I decided to do, by myself, I went out and bought the punching bag, the gloves, the wraps, educated myself on technique, etc. Over time, the fun slowly went out of it - but because I started thinking of it as a workout.

The important thing to take away from this is that working out in is something that you have to enjoy - for now, in the winter, that means biking for me on an indoor bike.

Now, my work-in plan!

Monday - 45 minutes on the exercise bike, as many chin ups as I can pull off (close to 2 -_-), and core exercises, looking at planks, sit ups, etc. Basic toning.

Tuesday - 45 minutes on the bike, more if I have the time.

Wednesday - Starting to get busier! 30 minutes high intensity - hardest difficulty almost the entire time. Toning and core as per the other days, if time allows

Thursday - I don't have time to workout. I have class all day :(

Friday - Same thing. Also, this conveniently gives me two days of rest during my week!

Saturday - When I can, I try and switch things up here. Do more toning, core, and a little bit of lifting (the ladies have to see my arms, y'know?) with my weights for my arms. This also works core, so is a dual purpose exercise.

Sunday - Technically the day of the lord's rest (Used to be a catholic - old habits die hard!) But as long as I remember and aren't too tired, I do another 30 minutes to an hour, depending on available time on the exercise bike.

Hope this answers some questions! Get back to me in the comments section and let me know if it doesn't.

tl;dr - I'm focusing on cardio, and I walk anywhere I can.

Random link - I have friend whose brother runs an LSAT prep school. He's marketed as one of the best out there, and with highly competitive pricing! Check it out if you're interested in the LSAT - I am! LSAT Prep

Whistl-at-er!

Hey all!

My play on words for my title was so bad this week... I want to apologize. But what's written cannot be unwritten!

Not me - BUT INSANELY HAPPY GUY
I have been lacking in terms of my postings, because I went to Tofino with my family! See my sister's blog Em's Blog! for a full explanation of our time there.

But then I got back from Tofino, and was scared to weigh myself. We ate a lot in Tofino, and I was worried that I had gained. BUT I LOST!

I am now 281, and feeling great! Lighter than I have been in a couple years, and singing like a beast, working out etc. I love it.

My drink of choice
So I gave myself a treat. I went to Whistler with some friends for a night! Partied it up, drank (alot) and had a blast!

Anyways, the play on words is actually relevant! When I was waiting for the greyhound, I actually had a girl check me out, for the first time in ever! Caught her staring at me twice - felt really good about myself after that.

So there are noticeable differences! It's cool. I will post a picture of me in the near future - show the difference!

IT'S A TRAP!

I figured it out!

My problem is portion control!

During my vegan week, I felt pretty awesome (yes, it`s over, and no, I don`t think I`m going back to it full time. Maybe a week a month or something)

The point is, during that week, I ate as much as I wanted, didn't feel guilty about anything. Problem is, I just came back from the SFU food court, trying to find healthy food. Got some noodles and such. They weren't horrible, but the amount of food I got was excessive. And then, of course, being me, I ate it all.

I was hungry! I hadn't eaten today! I had no time to prepare a lunch! 

All bad excuses. I shouldn't have eaten it, or at least so much of it. SIGH. Gonna have a long workout tonight, maybe an hour on the bike once I get home (at 10 PM...).

Here's a picture that inspired me, on the side. 


Ahh, General Ackbar - you never fail to make me laugh!

Thanks for reading guys.

Check out this video - it's funny!

Update: Had a workout tonight. 760 calories, 45 minutes on bike. WOOHOO!

Basil Metawhosiwatsit?

So first of all, I'm confused today.

Yesterday I wasn't hungry all day, so I didn't eat very much at all. I had a grapefruit, some hummus and flatbread chips, some healthy stir fry by Mum that night, and some tofu. Also a couple things of tea, and I worked out.

What I don't understand is that I gained weight. WTF body.

There's no way I took in over 500+ calories yesterday. Even if I did, my BMR - I know, not the basil Metawhosiwatsit, but rather my Basal Metabolic Rate, is really high.

The BMR is the rate that your metabolism passively burns calories without you doing additional work to prod and push it to burn more (aka cardio).I calculated mine at two different websites, within 5% of each other the results were the same. To see what your BMR is, Click Here!. Mine on this site was 2666.3 calories, assuming being in bed all day.

So following my math correctly, I burned 2666.3 (BMR) + 500 (Workout) = 3166.3 calories burned. Not including the fact that I wasn't in bed all day yesterday, but was in fact tutoring, singing, walking, etc. But first thing this morning, when I weighed myself, I was 285. WTF BODY.

Can someone explain to me exactly how, when I have that many burned calories, that little intake of calories, how I could possibly have GAINED weight overnight. I don't understand, but damn I want to know.

Thanks for listening to my rant :)

Also, my veganism ended today. I haven't decided if it really has or hasn't yet though - I'm a thinking.

Update: Had a 45 minute bike workout, 900 calories down dem tubes. Yeah!

The End of Days.

For me at least. My veganism ends tomorrow!

However, I think I have had a change of heart. Originally, I was only going vegan for a week. But I think that has changed. I'm going on a family trip to Tofino shortly, and to eat vegan there is very difficult and pricey. So I think that for the time I am in Tofino, I will eat whatever the rest of the family is eating (except my sister, she will still be vegan), and when I come back, shall reassess the situation.

Though I am leaning heavily towards veganism if not vegetarianism.

I like what it does for me. I have lost significant amounts of weight, feel like I have more energy, am happier, and my workouts feel better. Less arduous.

That being said, I am up a pound today >.<

Foolish Greg! Damn that hummus sitting there in the fridge with those tortilla chips nearby! They were so tempting at 11 o'clock last night - irresistibly so. I ate a bunch of it, and before I knew it, was out of chips. That's where the pound came from, SIGH. Oh well. I have another day of loss before a return to normal and maintaining!

Also, for those interested, these are two of the single most creative and talented guys I have ever seen on Youtube - check them out. They are incredible! The Piano Guys . A friend told me about them, and I am going crazy for them.

So far today, I had a grapefruit, some hummus and flatbread chips (so irresistible!) and a few glasses of water.

On the note of my family vacation coming up - I am looking for some music that my family would enjoy. They enjoy almost all kinds of music, but with minimal swearing, and ideally something I can torrent, since I don't have much money. Leave your thoughts and suggestions in a comment below! Thanks all.


That's all for today!

Update: Long day so far! Waiting at Starbucks for my debate executives to arrive so that I can plan the last details of the tournament I'm running this weekend. Awesome! Also, had a workout - 500+ calories, half hour on the bike! Didn't have much time today between tutoring, vocal jazz, midterms, papers, job hunt, Ututor, and debate. Oh well!
