Week 7 - 5.6 Pounds Lost

Update for Week 7, ending 2013.02.22

Now that we're leading up to the final week things are getting a bit more interesting.  In week 7, my official weigh-in at work is 198.6 lb (starting weight of 235.0 so a loss of 15.59% - I'm the first to break the 15% weight loss milestone). As a group we've collectively lost over 300 pounds - quite a lot .

Carlos is still creeping up towards my percentage (well, I guess they all are for that matter).

At home, my weight comes in on Friday at 194.8 lb for a total loss of 31.8 lb (226.6-194.8). I ended up hitting my 195 lb target and set a new target of 185 lb which I won't hit by next Friday, but it should end up with me somewhere on either side of 190 or so. The next couple of days will determine where I end up by the end of the competition.

My progress via graphs generated from MyFitnessPal:





The increase in my workout intensities seems to be working - I dropped quite a bit more than I expected and dropped another full pound today (Saturday) that's reflected on the graph. I'm still consuming around 1200 or so calories (even though the graphs make it look like I'm eating half of that, it's due to the reset of my goals for the third time). No adverse effects (nausea, light-headed-ness, etc). I've also increased my consumption of vitamin and mineral supplements to twice a day on the multi-vitamin.

Metabolism when Dieting

One of the things I've tried to maintain while dieting is a good balance of quality calories to exercise. Once again, I'm no expert and these are opinions I've concluded via research and experience while dieting and working out. There are a couple of things to consider when trying to lose weight: First, are you just trying to slim down and don't care about muscle loss; Second, what does your metabolism and chemical balance look like at the end of a diet cycle?

The Problem with Dieting Through Calorie Restriction

It's pretty much a given that you'll lose weight if you reduce calories - this has been studied and implemented time-and-again, both voluntarily and involuntarily. You should understand that when your body begins to starve for the lack of your usual supply of calories, it starts feeding on the tissues that are available - first you end up losing water weight, then muscle and finally fatty deposits. I don't think people understand this - it's easier for your body to process and utilize proteins stored in your body as muscle mass than it is to use fat. Your body is engineered genetically to keep as much stored energy as fat as possible, so it will always prefer to burn muscle before fat - the result is that yes you are thinner but the cost is severe - once muscle tissue is spent and you've reduced your weight, it's much harder to recover that muscle. When you start consuming calories again, your body naturally tries first to store the energy as fat before contributing to muscle regrowth, especially if you live a sedentary lifestyle. To offset this loss of muscle you can do two things: use weight training to balance out the loss; and secondly try to attain a state of Ketosis by carbohydrate reduction (as already described in my previous post regarding the Adkins Diet). While in Ketosis your body can utilize the lipids (fatty cells) as energy as they are able to cross the brain-barrier.

Spot Reduction

This brings us to spot reduction - I'd define this as "I'm trying to tighten up my stomach so it's flatter" and results in all those wacky machines and self-help aids that were all the rage on "As Seen on TV" ads (GutBuster, etc). Frankly, for the most part they don't work. When you lose weight, you lose it over all your body in a fairly consistent manner. There is no such thing as targeting weight reduction to a specific spot on your body. I say "for the most part" as the exercises itself can promote some muscle tightening, however when the muscles are covered in a layer of fat, who cares if they're tight or not?

Metabolism

The second thing to think about is what type of metabolism you end up with at the end of a diet cycle. You want your metabolism elevated and not depressed. If you restrict your calories too much your body rebels and slows down your metabolism - in effect, your weight loss becomes stalled (I've heard this called "Starvation Mode" often used as a warning when using Weight Loss apps to avoid liability). This is a survival thing ruled by millions of years of evolution and genetics.

Some Mistakes People Make that Screw Up Your Metabolism

Cleansing Fasts - this is basically when you go on some type of fruit-juice diet that causes you to take a quick dive in weight reduction. The issue here is that you end up losing an inordinate amount of muscle mass. Second, fructose (the sugars found in juices) are processed in the liver. It's possible to do some heavy damage to the liver when you do nothing but fruit juices - when eating high fiber fresh fruit, your body moderates the amount you can absorb - the fiber fills you up so you can't consume more than what can harm you - by drinking juices you bypass your body's natural defences and load up the liver. If you look at the 10 things that drinking ethanol (booze) does that are bad for your body and liver, fructose does around 7 of them. Second, energy processed by the liver can only be stored as fat since it isn't readily available for use. Unless you're in a state of Ketosis (which the fruit juices will prevent you from attaining), your taking big risks both to liver health and your loading up fat. All bad, no matter how you look at it.

Drinking Diet Soda - yeah it's zero calorie so it must be OK to consume while dieting, right? Wrong. It turns out that when you drink Diet Soda your brain thinks it's about to get sugar and triggers a chemical response. This causes a release of the hormone insulin which can lead to metabolic issues similar to diabetes - mood swings, sudden drops in energy, the list goes on and the results are all bad.

Not Eating Enough Protein - so many proteins carry a lot of calories, especially red meats as they also carry lots of fat. It becomes natural when you're counting calories to try not to eat those foods with the highest calorie count, so many eat less proteins. It's much better to adjust the type of protein you're consuming instead - an ounce of lean beef has about 71.3 calories (5.2 grams of protein and 5.4 grams of fat). The same in one ounce of chicken breast (boneless, skinless) has 35 calories (5.32 grams of protein and 1.38 grams of fat). This is due to the calorie cost of  protein vs fat: protein has 4 calories per gram and fat has 9 calories per gram. The number of calories in meat and poultry depends on the ratio of fat and protein. The leaner the meat is, the fewer the calories. The bottom line is to avoid high-fat proteins in preference to low fat proteins like white-meat chicken and fish, instead of forgoing proteins altogether to avoid the calories.

Not Taking Vitamin and Mineral Supplements - when you limit the amount of food that you intake, it tends to pass even faster through your system than normal. I believe this to be a result of an increased metabolism - in any case, combining a shortage of food AND the quickness of digestive flow, you should be taking vitamin and mineral supplements. In fact, if you think you're currently taking enough, you should probably double what you're taking. I tend to do a broad range multi-vitamin in the morning along with a light breakfast and some additional vitamins that I've found to be helpful. At minimum you should be taking  supplements (always with food) at least once a day and preferably twice a day (or more). Do be careful with those vitamins that are not water soluble (Vitamin A is an example) as it's possible to consume too much, which causes a detrimental effect. Research is your friend.

It's entirely possible to make yourself sick when dieting, especially extreme dieting. Make sure you select good quality foods and carefully adjust your diet and exercise if you don't feel well. Working out and dieting shouldn't feel bad (well, except for some stomach grumbling and a bit of soreness) - if you have any doubts, consult your physician.

Week 6 - 2.8 Pounds Lost Plus a Couple of Surprises

Update for Week 6, ending 2013.02.13

OK, the competition is starting to get fierce! In week 6, my official weigh-in at work is 204.2 lb (starting weight of 235.0 so a loss of 13.11% and I'm still in the lead). As a group we've collectively lost 94.1% of the weight we started with. The new individual member milestone is with Jeff B, who has dropped from the obese category (BMI 30.0).

Now for a couple of surprises:
  1. Carlos L is creeping up to my weight loss percentage at 12.72% to my 13.11% and could overtake me next week. He's lost an incredible 32.4 lb for an average of 5.4 lb per week - very impressive.
  2. Second, seems Kevin Lu has been in stealth mode this entire time (he hasn't weighed in until this week). Kevin started out as the lightest in the group and the only member who was within the "normal" BMI at 24.9. Friday he shoots up from last to 5th place. His advantage is that he only needs to lose a few pounds to make significant gains. It's also his disadvantage, as he doesn't have much in excess to lose.

Total 100% 94.1%

At home, my weight comes in at 200.4 lb for a total loss of 26.2 lb (226.6-200.4). I'm fairly certain I'll hit my 195 lb target (I dropped to 198.8 on Saturday) so I may need to set a new goal target, perhaps of 190 lb (which will change my work target to 17.45%). The next couple of days will determine where I end up by the end of the competition.

My progress via graphs generated from MyFitnessPal:





I've been slowly increasing the intensity and time of my cardio workouts - I started on the treadmill at incline 5.0 and speed of 3.5. I'm currently starting at incline 7.0 and speed of 3.7. This week I go to 8.0 and 3.8. I also started to work in some stationary bike - I've committed to a bike ride the first week of April: The Brag Spring Tune-Up: http://www.brag.org/stu2.html
The ride occurs around the town of Madison, GA which has fairly level paths and gentle hills. Sounds like a lot of fun. The last ride I did (on the Silver Comet), I came away fairly saddle sore - this time I hope to build up a bit for the soreness. I'll also be riding as often as I can locally to prepare.

The Adkins Diet and Eating Healthy

I wanted to write a bit about eating healthy while dieting. Admittedly, I'm no expert on the subject as I'm not a nutritionist, however through many years of research and experience I've come up with some conclusions.

The Adkins Diet

I think I've been dieting off-and-on since the late-80's - I think that's when I first noticed a bit of a gut and loss of energy associated with weight-gain - as the decade closed and the 90's started, I also became more sedentary. When I finally decided to do something about it, I started researching the Adkins Diet, as it was the "flavor of the week"  and was in the news quite a bit. I'd see these news stories showing huge pans of sausage, bacon and steak being cooked with the idea that you can have all the fat and protein that you can eat, as long as you limit your carbohydrate (hereafter revered to as "carb") intake. So I took it upon myself to research the diet and picked up a copy of "New Diet Generation" - it was an updated edition of Dr Adkins best selling book.

A little background on Adkins - seems he was a successful MD that found more-and-more of his practice made up of the elderly and diabetic. His initial foray into using diet as treatment was to attempt a through-diet approach in balancing sugar levels in his patients. That led him into formulating his treatment as a commercially available diet via his book(s). Through many years of application he found what works and what didn't work, so from a purely scientific perspective there was (and still is) a lot of controversy surrounding his dieting theories.

Regarding the diet - I know that many who are reading my blog have tried it before, but the question I always ask is "did you actually read the book" and if so "how far did you get." The answer is interesting - I've actually read the book and also did an additional layer or two of research, reading the many opinions or anecdotes of both the various proponents, and detractors of the Diet. What I've found is that almost no one that I know who claims to be doing or has done Adkins, has actually read the book. I guess that's common, as much of the information regarding the diet is freely available online (it wasn't so much back in the early 90's when I first started with it). Of those that have read a bit, most don't really understand it, or they didn't get very far into the book or other resource before starting the initial stage of the diet - once again, to be expected as how much do you need to understand in order to benefit from the Diet? The answer turns out to be a lot.

This is the scenario that usually plays out: In the first chapters or so the Diet calls for you to force a state of Ketosis - basically you have elevated levels of Ketones in your body (Adkins describes the use of Ketone test strips that you can use to detect if you're in this state or not). This is the underlying foundation of the Adkins Diet - when you have elevated Ketones via the Diet, you've basically restricted your carb intake to the point that your liver glycogen stores are depleted. This causes your body to use fatty acids instead of glucose (which is in short supply) for energy. The result is that your body uses the stored fat in your body for energy instead of depleting muscle tissue (those proteins are much more difficult to utilize as energy than the lipids). This all sounds good, right? A byproduct is that you can basically consume as much protein and quite a bit more fat than you normally do because whatever can't be used by your body as energy is passed as waste. Sounds great so far, right? and that's usually the hook that everyone buys into and after reading that to start, reduce your carb intake to about 30 grams a day. So most who read the book or do the research stop right here and start eating massive amounts of animal protein, eggs, etc.

What gets missed is that doing this forced state of Ketosis is pretty rough on the body - it really shouldn't be sustained for very long (Adkin's recommends 2 weeks in this state), then the carb intake should be gradually increased until your body is at a state of slightly Ketonic equilibrium -so over a period of several weeks, you gradually increase the number of carbs your eating until you reach a state where you're still losing weight, but eating an appropriately amount of carb calories to maintain good health. Instead, most continue in that first 2 week state of high Ketosis for weeks on end and in fact go overboard, by eating massive amounts of meat and fat in lieu of anything else (like green vegetables and other stuff that makes up a balance of good calories). Ultimately either your body suffers from this, or you get so bored with the diet that you start eating all the stuff you shouldn't be again, causing you to break out of Ketosis and if you're like me, you see-saw between losing and gaining. The result - you initially lose a bunch of weight but as soon as you blow the diet, you gain it all back quickly, repeat ad nauseum.

Since I actually read the book I was fairly successful in losing weight, at least the first time I did the diet. I also did two things that most don't do: I took an elevated amount of vitamin and mineral supplements; and actually followed the diet by gradually increasing carbs through good quality foods, mostly raw or near-raw vegetables.

The first is often over-looked by dieters - it's my opinion that when you do any type of dieting, you end up pushing food very quickly through your body (whether it's calorie restriction or a fad diet), thus decreasing your digestive system's ability to harvest those vitamins and minerals in food - the raw materials simply don't stay in your system for maximum effectiveness, so you should bolster the availability through the use of supplements. This is compounded because of the notion that you can eat all the meat you want (often ignoring any veggies that are available) as it processes quick and there aren't much more than fats and proteins in what you're eating. In the real Adkins Diet (which means you're typically a patient in one of his clinics, have medical supervision and a custom plan done just for you), you're taking a broad range of supplements 4 to 6 times a day. It sounds like overkill, but does parallel my own experiences. It also makes sense to me.

The second aspect, gradually increasing carbs, is super important. Treating the Adkins Diet as a fad that you can pick up or drop off at whim, is a huge fallacy. Real proponents of the Diet realize that to make the diet work, it takes an actual lifestyle change. This latter is where it typically failed for me. I simply didn't have the commitment in me towards a total change in what I was eating - I would get to the point where the Diet seemed to deprive me and naturally, I would rebel, causing the see-saw action I've already described.

This time I've gone to true calorie counting, being very honest in my evaluation of the calories I'm consuming - now so much easier through the use of apps like MyFitnessPal - it's actually become easy to do this (and previously, this was the hardest aspect of any calorie restrictive diet and why they never appealed to me).

Eating Healthy

I guess my second topic is really more about eating the right balance of good, high nutrition foods. In general the problem with calorie restrictive diets is that people end up just counting calories and when they get close to their limits, they stop eating. This would and is fine if both the mix of foods and the quality of calories are considered when counted towards this goal. What I've found in practice is that most people will pick up a bag of chips, count the 160 or so calories, and add other crappy food sources until they hit their limit. Since the quality of the food is poor (both in nutrition and especially in fiber), the person using this casual technique will get very hungry after they hit their goal and cheat. Or, if they don't cheat, they end up with weird health side-effects because they aren't eating calories that are mineral or vitamin rich. I don't know about you, but to me either result is a recipe of failure at best, and disaster at worst.

Think about this - if you're basal metabolism requires 2200 calories to maintain your weight, that means that to lose 2 lbs per week you get a threshold of about 1360 calories per day (via MyFitnessPal). If you fill up those calories with junk foods your taking a huge health risk, even if you're taking supplements. Those supplements are no substitute for the minerals and vitamins you absorb through real vegetables, fruits, meats and grains. First there's no guarantee that what you're taking in supplements will be readily absorbed. Second, you may still not be getting what you're body needs - supplements should only be treated as a bit of insurance and not a true substitution.

I suggest a good balance between proteins, fats and carbohydrates. I actually don't agree with what is recommended by the FDA or AMA (I've mentioned this before), as when dieting with exercise I think it's important to boost the amount of proteins you're taking to avert the loss of muscle mass. To me the ideal diet is heavy in proteins with room for as many fresh green vegetables as you can pack in (they have negligible calories) and a smaller portion of whole grain carbs - these should be eaten early in the morning so you have the day to burn them off - they also provide some energy for your activities through the day. I stop eating sugar or sugary foods altogether (no juices either) because when dieting the complex carbs are your friend (takes much more energy to break them down). I also avoid most fructose unless I'm eating fresh fruit - the additional fiber you get from fresh fruit offsets the fructose you're consuming (it becomes more of a byproduct) - stick with berries for the most bang-for-the-buck.

Finally, let's talk a bit about food quality. I think it's a shame that in the United States, where we produce enough food to feed everyone who lives here to excess, at both the conditions of starvation AND obesity exists. Much of this, in my opinion, is due to the commercialism of food in this country and the poor quality of most cheap staples. The more I research this topic the more convinced I am that food production in this country will be found as the cause for the many ailments occurring in people as they age. We put so much effort into quantity-over-quality that what's being produced is just shit. Yes there's plenty of it, but what are the consequences? If you don't know what I'm taking about, compare a tomato grown via conventional methods to an heirloom grown organically. The first will be pretty, big, have questionable texture and be almost tasteless. The latter will be smaller, taste better, and have both a higher nutritional value and fiber. The problem is that the food industry in this country breeds and grows first for yield (size and number), second for appearance (people want RED tomatoes) and third to be grown in multiple climatic conditions. This all produces a lot of crap produce and because it has so little flavor, when processed the manufacturers add a lot of salt and/or other sodium to boost what little flavor remains.

Anyway, I've had my say - I hope there's food for thought in there.
