PUT TIME ON YOUR SIDE

Tuesday, September 15th, 2009

There’s nothing worse than having these big plans to be in great shape by a certain date … only to realize you’re not going to make it. Why? Because you started too late and didn’t give yourself enough time. It’s always best to err on the side of caution and give yourself more than enough time, rather than not enough time. After all, there’s nothing wrong with being in shape too early.

If it’s your first time trying to take your physique to places it’s never been before, the advice to start early is even more prudent. Everything might look great on paper – the perfect diet, the perfect training program and all the motivation in the world – but you just never know how your body is going to respond. Maybe you’ll be one of the fortunate ones for whom it all works like clockwork. But for everyone outside this category, what tends to happen is they realize they’re behind schedule and they try to play catch up by trying to ‘fast forward’ fat loss.

The next thing you know you’re doing more cardio than you need to be doing, and eating less calories than you should be eating. Basically, this one mistake forces you to make other mistakes. The next thing you know, you’re saying goodbye to some of your hard-earned muscle. It’s better to be safe than sorry, so give yourself ample time to meet your deadline. You want to work with your body, not against it. When you work with your body, it will respond. When you work against it, it will react.

How much time do you need? This of course depends on one, what is your end goal, and two, how far away from that end goal you presently find yourself. It’s difficult to say how long you’ll need to realize your fat-loss goal as everyone is different. The more weight you need to lose (and therefore the higher your body fat percentage is), the faster you can lose fat. As you get leaner and your body fat is lower, your rate of fat loss will decrease. On average, you’re probably safe to bet on about 1-1.5 lbs of fat per week, again recognizing that in some cases it can be more (if you have high body fat) and in the case of the already fairly lean, it will be less. Basically, in the beginning you can generally lose a lot of fat fast … but towards the end you tend to have to work even harder for less results, as those last few pounds of fat, take a lot work, and lot of patience and a lot of commitment.

In addition, it’s also wise to remember that fat loss is not a linear phenomenon – some weeks may produce better results than others. The take home point is that if you’ve set a deadline, make sure you give yourself enough time to meet your deadline.

The Meal Frequency Myth

Thursday, May 28th, 2009
Meal frequency isn’t really a topic that comes up too often when talking about optimal nutrition as it seems that these days no one questions the fact that six meals a day is optimal if you’re serious about your physique goals. But is it?

My answer would be, optimal for what?

This tends to be one of those long-held-to beliefs that says that the more often you eat, the more fired up your metabolism is. In that context – no. It’s not.

Metabolism is determined by the total energy intake, not by how many meals you get it in.

2000 in 4 meals vs. 2000 in 8 meals is still 2000 calories and your body still has to spend the energy to process that same 2000 calories.

Myth! Myth! Myth! (and one with much research to show it – 24-hr indirect calorimetry, etc.) Some of the intermittent fasting guys, such as Brad Pilon and his Eat Stop Eat program for example have gone into more scientific detail explaining why meal frequency doesn’t hold any magical fat-loss benefits.

The idea stems from something called the Thermic Effect of Food (one part of total metabolism), which is basically the energy cost to digest incoming energy (this differs for the various macronutrients). So the idea is that the more often you eat, the more TEF goes up and the more the metabolism goes up. The problem with this is that it’s a bit of a misrepresentation as TEF is actually correlated with the amount of calories in the meal, and therefore total calories at the end of the day.

Rather, it seems that an inconsistent meal frequency is what has potential negative effects.

So from a direct fat-loss standpoint, there isn’t really an advantage to 8 meals vs. say 4-5. There are however other advantages you could potentially argue for:

  • More stable blood sugar
  • Possible health benefits
  • Control of hunger
  • When calories are very high (easier to get them in with more feedings rather than less)
  • And subsequently, dietary compliance, which is the key to any diet.

There’s no disadvantage to a high meal frequency that I can think of, so if you prefer it, stick with it. If you find it hard, you can cut back on the meal number and just make your meals a bit bigger.

(Note – that doesn’t mean all your calories in one meal per day.)

I still eat 6x/day and I use 5-6/day with clients as well. The only time I go lower is if they complain that they can’t eat that often. For me it’s just more convenient to eat frequently. I work from home and have access to food whenever I want, so it’s a no brainer for me. For others, who are very busy, and simply don’t have the same amount of available time, less meals is likely going to mean better dietary compliance.

Meal frequency should be assessed on an individual basis and meal number for the day should be decided based on what best fits into a person’s lifestyle.

Aminogen® Increases Protein Absorption!

Friday, May 22nd, 2009

Aminogen® is a patented blend of digestive proteases (Apergillus niger and Aspergillus oryzae), which are enzymes that breakdown protein, aid in digestion and increase absorption. In a fairly recent study published in The Journal of The International Society of Sports Nutrition, researchers put Aminogen® to the test. The results were astounding!

In this clinical study, twenty-one healthy male subjects were given 50 grams of whey protein concentrate (42.5 grams of protein) with and without Aminogen on separate occasions. Results showed that when subjects consumed whey protein concentrate and Aminogen® the rate of absorption increased by as much as 350% in comparison to taking whey concentrate on its own. Look for Aminogen® in advanced protein powders, such as MuscleON™ .

Spice Up Your Fat Loss

Monday, April 27th, 2009

The thought of dieting for fat loss conjures up images of bland, boring foods, such as plain chicken breast and tuna. Not the most appealing of thoughts, but hey, no one ever said dieting was fun. Seasoned bodybuilders have learned to make these foods more palatable by adding spices to increase flavor and enjoyment.

A recent research paper also supports adding spices to food not only increases flavor, but also thermogenesis. Consumption of capsaicin, black pepper and ginger all have been shown to increase thermogenesis through several mechanisms and most commonly through the stimulation of catecholamine release. Catecholamines, such as epinephrine and norepinephrine (a.k.a. adrenaline and noradrenaline), are chemical messengers released from the adrenal glands and nerve endings, which stimulate fat cells to breakdown and release fat.

So if you’re planning on getting ripped this spring, try adding these spices to your food, not only for the flavor, but for the fat loss as well.

Muscle Building Nutrition Q&A – Part 4

Tuesday, April 21st, 2009
Ok, so we’ve established answers to the following questions in the first three parts of this series so far:
1. Would I have to do a bulk?
2. How long would I bulk for?

Alright, how about some practical steps? We’re not going to get into the training aspect of this right now as it’s a rather varied topic, so we’ll just keep the focus on nutrition – which really is what will be the final determinant of gains. By that I mean, I don’t care how hard you’re training, if you’re not eating enough to support muscle growth, you’re not going to be gaining size. Period. (exception to the rule – newbies and those new to ‘effective training’)

To go back to another point made in one of the previous posts – expect to gain at least some bodyfat. If you expect to stay lean, expect to stay the same. I’ll give you a few case examples:

1. I was emailing back and forth with a client prospect who has been solely focused on muscle gain for many, many months. She works with another trainer. In our communications, she ended up sending me her pre- and current ‘bulking’ pictures for review. First thing I noticed? Nothing. Literally, I couldn’t tell a difference at all. I asked her what the difference in weight was. The answer? One pound. I believe this was over the course of about nine months. ONE POUND. Now, it’d be great if there was some massive recompositioning here but there wasn’t – no visible changes. I questioned her on this and she said her trainer wants to her stay lean while gaining size.

The results show how effective that strategy is.

2. A client of my own who I worked with for a little over a year. We did a few cut/bulk cycles and yes she gained some body fat during the bulks. But she had a great mindset for all of it (vital necessity in my opinion) and had the big picture in front of her the whole time. The numbers will make my point for me.

November 19/07

Weight – 110 lbs

Waist – 30 1/4

Hips – 33 3/4

Thighs – 17

Chest – 31 1/2

Arms – 9 1/2

Calf – 10 1/2

Contrast that to her final biweekly:

September 16/08

Weight – 109.4 lbs

Waist – 24 1/4

Hips – 33 1/4

Thighs – 17 3/4

Chest – 32 1/4

Arms – 10

Calf – 11

The most glaring point there is that she weighs basically the same as her starting weight – but her waist is 6 inches smaller. Now that’s a recomp.

A successful bulk is obviously determined by the results gained – hopefully you’ve added some muscle and not too much fat. It’s fine to gain, gain, gain, but if you end up the same bodyweight and the same bodyfat – basically you look the same as you did pre-bulk – it doesn’t seem like you did very well. Now if you end up the same bodyweight, but you’re even leaner (see Case #2 above) then you definitely had a successful run. Gaining 20lbs only to lose 20lbs and look no different – that’s not a good bulk.

How much do I need to eat?

Enough!

You need to definitely have more energy coming in than going out. Again, insufficient food intake = no gains. Look around the gym – most people there are trying to gain some muscle, get stronger, etc. Are they? They appear to be working pretty hard and yet, a year from now, chances are they’ll look no different. Something isn’t working. Could it be what they’re doing/eating outside of the gym? Could it be that they train hard for 45 minutes (trying to build muscle?) and then they hop on the elliptical for 30 minutes PWO (trying to get the cuts?). It doesn’t work.

So how much food? I generally recommend that you start at an assumed maintenance intake. I say assumed because all of the predictive equations are just estimates. They’re not going to necessarily be 100% accurate, but it’s a starting place for us. If you’re not coming off a hard diet, around 15x total bodyweight is a good ball part. Pay attention to results though – if you’re gaining (beyond water and glycogen) then clearly this is not maintenance. If you’re coming off a hard diet, start a bit lower as metabolism will be slightly depressed. Stay there for two weeks and reassess. Did the scale go up? Go down? Stay the same? Adjust accordingly. Assuming you were at maintenance, start adding calories. Again, we’re trying to avoid getting too sloppy so take it easy and just systematically raise them. Start at 10% above maintenance, stay there for a bit, and reassess. What’s happening? Nothing? Add another 10%. You basically continue to add calories until you start to see an upward trend on the scale, but not so quickly upward that it’s clear (in the context of expected rates of muscle gain) that you’re gaining too much fat per given pound of weight gain. If you are gaining too much fat, scale the calories back a bit. It’s all about a simple outcome based approach. Base your adjustments on your results.

Low Carb Diets vs. Low Fat Diets

Monday, April 20th, 2009

Let the debate between low carb and low fat diets end – science has determined the winner! In a four-month study conducted at the University of Cincinnati, 50 obese test subjects were divided into two calorie-restricted groups: 1) low carb and 2) low fat. The low-carb dieters followed an average protein/carb/fat ratio of 28/15/57 for the first two months and a ratio of 24/24/52 for the last two months. While subjects following the low fat diet had a macronutrient ratio of 18/53/29 for the first two months and 20/48/32 for last two.

What’s important note is that there was no significant difference in total calorie intake between each group. In spite of this, the difference in macronutrient breakdown showed a significant difference in overall weight loss and body fat reduction. By the end of testing, results showed that the low-carb subjects lost more body weight (21.6 vs. 13.5 pounds) and fat (13.7 vs. 7.1 pounds) than those following a low-fat diet!

Water – Nature’s Fat Burner

Wednesday, April 15th, 2009

Looking for an easy way to increase your metabolism and burn off more calories? Try drinking water. A study conducted in Germany showed that subjects who consumed 500 mL (2 cups) of water increased their resting energy expenditure by 30% after 10 minutes of consumption with the effect lasting up to 40 minutes. This study also found that the increase in calorie burning came from fat in men and from carbohydrates in women. The researchers speculate that consumption of 2 liters (8 cups) of water a day would additionally help burn off close to 100 kcal/day.

Whey Protein Promotes Weight Loss

Wednesday, April 8th, 2009

It’s no secret that whey protein helps increase muscle mass and strength, but a preliminary study presented at the Experimental Biology Conference has just revealed that it also aids in fat loss.

In this six-month study, 90 overweight subjects were divided between three supplement groups: 1) 60 grams of whey protein per day, 2) 60 grams of soy protein per day, or 3) 60 grams of carbohydrates per day. Each group consumed their given supplement in addition to their regular diet and did not follow a prescribed training program. They simple added the supplement on top of their diet and carried on their life as they normally would. The results showed that the group taking the whey protein lost the greatest amount of weight, which was 5 pounds more than those in the carbohydrate group.

Chew vs. Sip – Food Logic

Wednesday, April 1st, 2009

When your fridge has more fungus than a mushroom farm and your cupboards are bare, it’s tempting to consider dropping real food altogether. With the day-to-day grind of work or school and managing a serious training schedule – food prep is sometimes the last thing you want to do. The easy fix – just drink shakes for every meal to keep those nutrient counts high. WRONG! Throw in a good “greens” shake to get your daily veggie count up. And who needs a Foreman Grill right? WRONG AGAIN! While it seems like the easy solution, don’t do it. No matter how little time you have in a day, always try to make at least 50% of you meals solid, functional food.

A nutritional supplement is just that, a supplement. Your diet should be built around whole foods, with your powders and capsules augmenting your daily nutritional needs in the meals you cook. Protein, carbs and fats aside, studies are constantly being released listing the anti-oxidants, vitamins and even enzymes that we previously were unaware we needed have been in whole foods like fruits, veggies and meats all along. The food you eat is fuel, plain and simple.  So make sure you balance your meals, whether whole foods and shakes – not just for the purpose of building muscle and strength – but for overall health and function.

Don’t confuse the ease of taking supplements with the necessity of a balanced diet.  Someday we may all have flying cars and protein pills, but until then, eat a banana.

Muscle Building Nutrition Q&A – Part 3

Sunday, March 29th, 2009

Continuing on with the answers to the following questions …

How long should I bulk?

How long do I have to bulk?

(again, I am just using the term ‘bulk’, which I dislike to indicate a primary focus on gaining muscle)

The first ‘it depends’ answer was to counter with the question of how much muscle do you want to gain?

To that we add the following:

2. How much muscle do you gain when eating in a caloric surplus and how much fat you gain when eating in a caloric surplus – or basically your muscle-to-fat-gain ratio. This basically refers to one’s partitioning ability – simply where the extra calories go. Does it wind up in muscle cells or fat cells? Ideally all of it would go to muscle, but sorry, not gonna happen. You might as well accept it now.

Now ideally at least more of the extra calories are partitioned towards muscle than they are towards fat. What affects this? First and foremost, genetics. Some people simply partition more calories towards muscle than others do. The less fortunate partition more calories towards fat cells than they do muscle. So on the one hand you might have someone gaining more muscle for a given weight gain and some gaining more fat than muscle (sucks!) for a given weight gain.

So we have things like the aforementioned genetics, higher-than-normal testosterone levels and other optimally ranged hormones (lower cortisol responses, healthy thyroid levels, etc) as well as good insulin sensitivity in the muscles.

Scientists refer to something called the p-ratio when discussing the partitioning of calories. The p-ratio is again, largely influenced by genetic factors and varies little within a person. Diet, training, etc (basically lifestyle factors) have the potential to influence it about 5-15% – not very much.

So, that tells us there’s not a lot you can do to shift your own innate muscle-to-fat-gain ratio (or even your fat-to-muscle-loss ratio when dieting) beyond the relatively small (yet not insignificant) effect nutrition, training (and drugs) has on it.

So we obviously get that diet and training should be on point during a bulk. From a dietary standpoint, you obviously need to be certain you’re eating enough to sustain not only the growth of new muscle tissue but the maintenance of it as well. This is one of the biggest pitfalls of those seeking out more muscle – they don’t eat enough. You can’t build a house out of sweat people. No raw materials? No muscle. Ample caloric intake is the biggest factor to be aware of.

Training of course is important as well, but the supporting growth factors – hormones, caloric intake, etc. – determine how much you can gain and support. Training is just a stimulus. Many think that because they’re training heavy and hard, the muscle is just going to come as a result. Again, it’s just a stimulus – if the supporting growth factors are not there, it’s just not going to happen.

Ok, so this ties into the next point:

3. How much fat are you comfortable gaining? This is going to be determined by one, how much over maintenance you’re eating and two, the aforementioned muscle-to-fat-gain ratio or how well your body partitions extra calories. For those with better partitioning ability, more of their new weight is going to be muscle and less is going to be fat, so they’re probably going to have an easier time of it. For those less fortunate, it’s going to be a different story. They’re going to gain more bodyfat for a given weight gain. How much are you comfortable with gaining? Remember, you’re going to gain some. Expect not to and I guarantee you that you’re going to look exactly the same at the end of your bulk.

These three points are really the determining factors of the length of your bulk – how much muscle do you want/need to gain, how much muscle/fat do you gain when consuming calories in excess of maintenance (a requirement), and how much body fat are you comfortable gaining along the way.
