Day 231: Shaken and stirred

Day 231 - front

  • Weight: 139.0 lbs.
  • No workout today; next: Workout C, April 20 (makeup for today)
  • Total inches: 124.5
  • Protein: 131 g (0 g over target)
  • Calories: 2,100

The numbers from the last 220 or so days are all lies. Lies, I tell ya!

I screwed up royally.

I bragged about my daily protein shake to a friend last week: “Three cups 2 percent milk, a banana, 3 tablespoons of peanut butter, one scoop of protein powder …”

Friend (who happens to know a lot about building muscles and changing weight): “Just one scoop? Really? That doesn’t sound like enough.”

Me: “Oh, sure it is. I’ve been using that recipe since Day 1.”

Friend: “Are you sure?”

I was. And then the next day, I was not.

I checked.

Recipe version Protein (g) Calories
“The 4-Hour Body” [Amazon | iTunes aff. links] 75 970
My screwed-up version 48 880
My corrected version 74 1,180

Yikes. The actual recipe calls for “30 g whey protein isolate,” which I thought meant 30 g of protein powder or about one scoop. I really needed four scoops of protein powder to yield 30 g of protein.

Sigh. 

The scary repercussions …

  • I overcounted for each of the first 225 days by 90 calories and a whopping 27 g protein.
  • That means I took in 20 percent less protein than I thought, slowing my muscle growth by a possible 20 percent.
  • My measurements for protein and calories are inaccurate from Sept. 1 to April 13.

Using four times as much protein powder per shake means …

  • The cost of protein powder has quadrupled, since I’ll use it up four times faster.
  • The shake tastes much more chocolatey.

Sunday, I started using four scoops in the shake. I didn’t even think about the additional calories. I am that stupid.

After noticing the 1.2-pound gain in the last 7 days, I needed to double-check all of the recipe’s nutritional stats. I realized today, after running the numbers, that I had accidentally consumed 300 extra calories a day, a 15 percent jump from the 2,000-calorie target.

Sigh again.

I am extremely grateful my knowledgeable friend raised the red flag. It allows me to make the corrections and have more accurate numbers.

The first decision is to leave the pre-April 14 numbers alone. I’ll add a note to the spreadsheet, but trying to revise all the numbers in all the posts will be too much work for me.

The second decision is to revise my daily calorie target immediately. Because the protein shake costs 210 more calories than previously assumed, I am dropping from 2,300 calories a day to 2,100. We’ll see if my weight remains steady (as it has been for the past 3 months) or goes up with more muscle growth from sufficient protein.

It’s tough to face a mistake like this, a simple miscalculation that I could’ve caught months ago. But I feel better knowing that I might actually be on the right track, even if I can’t follow a simple recipe.

I can’t lie to myself.

Day 175: The myth that is the Nutrition Facts label

Day 175 - front

  • Weight: 137.0 lbs.
  • Workout C: 22 minutes, 40 seconds; next: Workout C, Feb. 25
  • Total inches: 123.3
  • Protein: 145 g (16 g over target)
  • Calories: 2,308

Reading the Nutrition Facts label on food is a waste of time. Unless you’re looking for a lovely fairy tale.

calorie data on foods for the New York Times.

As we’ve explored before, counting calories is more art than science. You must estimate the calories in cooking a recipe, or evaluating portion size. You must, with every bite, guess.

How woefully inadequate, whether trying to gain or lose weight.

Casey Neistat, a filmmaker based in New York, looked at foods he ate on a typical day in a report for the New York Times. The city requires restaurants to post calories on their menus.

Neistat bought five things from both stores and restaurants. With the Times’ journalistic resources at his disposal, he had those foods analyzed at the New York Obesity Nutrition Research Center in a bomb calorimeter.

(You could do it yourself, after spending several thousand dollars on the equipment, not to mention the training needed.)

Four of the five foods tested had more calories than reported on the Nutrition Facts label. Of the four, two were packaged items, while the other two were made at restaurants upon ordering.

Yikes.

He would’ve accidentally consumed 20 percent more calories than expected, some 549 calories.

Neistat asks in conclusion, “If the requirement to post the information (on caloric content) is going to be enforced, why not also enforce its accuracy?”

Oy, I may have wasted 6 months counting calories, when at best, I was counting pixies.

Day 88: Numbers game

Day 88

  • Weight: 132.6 lbs.
  • Workout B: 16 minutes, 47 seconds; next: new workout plan, Dec. 3
  • Total inches: 122.0
  • Protein: 129 g (4 g over target)
  • Calories: 2,102

Numbers are everything, and yet, don’t always matter.

This dueling set of principles has been the heart of my calorie counting for the past 3 months.

I count the calories every day, weighing every morsel of food. I’m currently shooting for 2,100 calories a day, but will probably go up to 2,200 in December, since my weight has been flat all month.

But I can’t weigh everything. When I dine outside the home, I have to guess. I’m pretty bad at guessing weights and sizes. But I try anyway.

And unless the calories per portion are printed on the packaging, I have to guess there, too. The Internet helps, but any number of sites will give different estimates.

I learned working at Southern Living about how trying to present nutritional information in recipes was a tricky proposition. Readers look for good data, but it’s hard to calculate perfectly. Burning food in a lab isn’t the same as burning calories in cells.

So even that recipe data can be flawed. What’s a numbers guy to do?

Be consistent.

My calorie count for my protein shake won’t be right every day. The size of the banana and the amount of peanut butter varies. But in the long run, it’s mostly right.

My portion sizes of pizza, chicken or taco salad are measured, but again, not perfect. As long as I measure the overall trend (more muscles, more pounds, more total inches), I’m OK.

The fun part about calories is making it a game. I can easily hit 125 or more grams of protein each day. Getting calories to the right number is more complicated.

I have any number of foods I can use at night to zero in on 2,100. And I don’t mind varying portion sizes. I am not cursed with hunger, so eating less on any given day isn’t a problem. I’ve even balanced out high-calorie days with low-calorie days.

It’s mildly annoying to have to weigh food several times a day. It’s mildly rewarding to hit the target number over and over.

I still pretty much eat what I want. Right up until about 10 p.m., when all accounts are settled.

The numbers are my friend, pushing me to keep going and keep tabs on progress.

Day 5: Setback! Aiyee!!

Day 5 - sept 5

  • Weight: 122.2 lbs.
  • No workout today
  • Total inches: 114.4
  • Protein: 116 g (on target)

I’m close to my starting weight and size. Panic!

Not really, but the trouble with tracking numbers is becoming lost in the data. Five days in, and it’s going in the opposite direction.

Having crunched millions of pieces of data over the years, I know how important it can be to look at both the big and the little picture simultaneously. Five days isn’t enough to judge anything on.

(Part of it can be attributed to user error. Each day, I can’t seem to measure each thigh properly, because I can’t get the measuring tape around my leg in the same exact location every time. Arms, belly and hips? No problem. Thighs? Like measuring a wet cat.)

Target weight: Days 1-5

Do I eat more? No. Do I work out more? No.

I kinda wish I could ignore the numbers for the next 25 days, but I know they’re keeping me on track, even if each day isn’t perfect. I’ve read friends’ diet blogs, and I know from their years of daily blogging that they have triumphs and setbacks. But in the end, they lost hundreds of pounds because they kept at it.

I’m not panicking. I’m enjoying the ride, wherever it takes me.
