My blog has evolved considerably since I first started it in 2004. I still attempt to update it with sometimes relevant and/or random observances as often as possible, but I can never promise which way the wind will blow on these things. Change is the only certainty.

Myths of Weight Management: If You Exercise, You Can Eat Whatever You Want
Some people, when they begin an exercise program, believe their effort to be so significant that they think they can ignore the input side and still achieve weight loss. Some may look at the calorie calculations on the cardio machines or their personal tracking devices and assume the calories burned will generously surpass the calories in their post-workout smoothie and end up grossly over-estimating their calorie output. For 150-pound person on a treadmill, 5% incline, 4 mph, for 20 minutes this output is around a modest 170 calories.
On the positive side, understanding the energy intake versus output balance may also help sway someone’s choice in snacking (e.g., looking at the calories contained in a few pieces chocolate and deciding if it’s really worth the 66 calories and additional 8 minutes on the treadmill to burn them off).
This discussion might also present an excellent opportunity for health and fitness professionals to discuss nutrient density and the effect of nutrient choices on exercise performance.
On the other hand, try that mega-chomp down with a big bag of broccoli or a pound of lean steak like a filet. I’m guessing that your satiety meter would register well in advance of a clean plate. That’s due to broccoli or steak’s high nutrient density (substance, minerals, vitamins, necessity of lots of chewing action…) when compared to its caloric density—you’d simply “feel full” much more quickly and sty that way much longer as your body works to break down all the nutrients. This is yet another method for evaluating the foods you’re eating. If it’s high calories and no nutrients, put that puppy back on the grocery store shelf and walk away!
