Four Stubborn Fitness and Nutrition Myths
/We've all heard them, and many of us likely believe them. So we're going to walk through some of the BIGGEST fitness and nutrition myths that have been around forever and often go unchecked...so let's bust these myths!
The sweet potato is healthier than the white potato.
This one just won’t die. No food, especially those within the same category, is “better” than the other. In this case, what one potato offers, the other lacks. Both offer quality carbohydrates and should be incorporated in most balanced diets for maximum benefit. Check out this great graphic from Precision Nutrition for easy comparison. THE SWEET POTATO IS NOT BETTER OR HEALTHIER, so stop using that as an excuse to order an extra side of sweet potato fries.
I can lose weight faster by lifting lighter weights with higher reps.
While this is a fairly popular idea, it can yield poor results (in the short term), and I hate to break it to you...losing weight is just not that simple. This is NOT the most effective way to lose weight. Lifting “light” weights is all relative to the strength of the individual, and your body adapts to what you feed it. So if you're only using lighter weights, the body responds by decreasing overall size and density of the muscle. Gaining and KEEPING strength is ALWAYS part of an effective program, especially a weight loss program. That is why it is important to include some heavier lifting in your program, even when the goal is not to maximize muscle gain and strength.
Weight loss happens when there's a caloric deficit, and this can happen by decreasing the intake of food (calories), working out and burning off more calories, or both. Our preferred method is to continue to push towards strength increases but at a lower intensity, to find less intensive ways to burn higher amounts of calories, and to keep the calories in a slight deficit. We do this by incorporating a multitude of rep ranges, stimulating multiple energy systems for maximal output.
A common mistake is to not incorporate low reps at higher weights during weight loss programs. Lower rep training (2-6 reps/set) does not require a large caloric intake to maintain nervous system excitability, but it keeps the muscle dense by recognizing the higher loads which aid in muscle maintenance and loss of body fat.
Here's an example of a weight loss inspired workout done at Tailored Strength:
Warmup:
Soft Tissue Release (2-4 min)
Mobility work (2-4 min)
Power/Nervous system priming (2-4 min)
A1- Main Compound Movement (Squat, Press, Pull, or Hinge) 2-5 sets of 3-6 reps (focusing
on maintaining and even enhancing strength)
A2- Antagonist Movement for Time or higher reps 2-5 sets of 40-60 sec or 12-20 reps
(focusing on increasing Heart Rate while supporting main movement)
Rest 45-60 sec
Weight Loss Circuit
B1- Upper Body Push 10-12 reps
B2- Single Leg variation 8-12 reps/leg
B3- Upper Body Pull 10-12 reps
B4- Core variation 12-20 reps or 45-60 sec time
Set timer for 14-20 minutes and get as many rounds as possible in the allotted time. Shoot to
increase this amount of reps each week!
C1 – Total Body conditioning tool (Battle rope, Rower, Sled, Air Dyne, Crawling,
Kettlebell)
C2- Additional volume for “show” muscles (arms, booty, abs, traps, calves, whatever)
- 5 sets of 30 sec -1 min Hard interval with C1 exercise, followed by 30 sec break, 30 sec- 1 min
moderate intensity with C2 exercise, followed by 30 sec additional break.
*Maintain same or better amount of reps or distance in C1 exercise each set! Increase total sets every 2 weeks
This ensures that rest periods are accounted for and HR is staying elevated for most of the workout, even between the longer rest periods of the heavy lifting in the front end of the workout. Maintaining and pushing strength will help with being able to handle bigger weights during the circuits which yields more muscle maintained, more calories burned, and better results!
Coffee (caffeine) is a diuretic!
A diuretic increases the frequency with which you pass urine. Yes, the more you drink, the more you pee. But we also "know" that we should drink more WATER and LESS caffeine. That's not a false statement, read more about why water is important in this old write up, but does drinking too much caffeine dehydrate you? Most of the recent data(1) indicates this is not the case. “Acute ingestion of caffeine in large doses (at least 250-300 mg, equivalent to the amount found in 2-3 cups of coffee or 5-8 cups of tea) results in a short-term stimulation of urine output in individuals who have been deprived of caffeine for a period of days or weeks.” In plain terms, this means that individuals who regularly consume caffeine (coffee, tea, energy drinks, etc) within a reasonable range, appear to have little to no diuretic effect. So yes, be sure to drink more water, but stop blaming your coffee consumption for not getting enough fluids.
White rice isn't as healthy as brown rice.
This is another classic “good vs bad food” matchup. Once again, no food should be categorized as good or bad, it’s all in the context of when we eat it, how much of it we eat, and whether we should be eating it. Brown and white rice are essentially the same grain, with the difference stemming from the milling process. White rice is milled down more and stripped of everything except the white endosperm of the grain while brown rice retains that bran and germ outer layer, making it brown in color. Brown rice does score higher on protein and fiber (5g and 3.5g/cup compared to 4.6 and .6g/cup) but with higher protein and fiber comes an increase in calories and fat.
Another advantage to brown rice is that it scores lower on the glycemic index, meaning there's less of a glucose spike after consumption. This is great news for folks who struggle with diabetes, but for all others, there's not much of a difference. Lastly, brown rice is far more micronutrient dense, most notably in magnesium, potassium and manganese content, but today's white rice is fortified, making both versions relatively the same.
So, after all of that, it all comes down to preference. White rice is basically tasteless yet more palatable for most as it can be flavored any way desired, while brown rice has a heavier grain taste. White rice is extremely easy to break down within the body and it's great for quick energy (think pre/post workout), while brown rice contains more fiber and can keep you full longer; it's outer bran/germ outer layer may be a little uncomfortable for some to digest. Finally, due to its higher nutrient profile, brown rice can offer a more “complete” dinner, especially for someone on a vegetarian or vegan diet, but can require a little getting used to when it comes to taste. So eat whichever rice you want...because when its all laid out, it doesn't really matter!
