Role of Exercise in Fat Loss
Part 6 of 6: Increased Caloric Expenditure
Increased activity does burn extra calories – a few… damn few. – Ken Hutchins
As we have been discussing the most important exercise factors for fat loss, you may have noticed a proverbial giant elephant sitting quietly in the room. Conspicuously missing from our discussion so far is our topic for today - increasing caloric expenditure through “cardio” exercise.
After a lifetime of my own experience with diet and the experience of talking with hundreds of clients about this topic over the years, here’s how the thinking usually goes:
- In order to lose weight, I know I must create a caloric deficit
- The bigger the caloric deficit, the faster the weight loss
- I eat very well and I like to eat whatever I want, so I don’t want to change what I’m eating or reduce my calories that much
- What else can I do besides reducing calories?
- I know, I’ll start ______________ (insert any “cardio” activity here)
OK, let’s put all of this together with the concepts we discussed earlier in the series:
1. In order to lose weight, I know I must create a caloric deficit.
TRUE!
2. The bigger the caloric deficit, the faster weight loss.
TRUE! But let’s ask a better question.
The bigger the caloric deficit, the faster the fat loss.
FALSE! We have to ask ourselves, do we want to lose weight indiscriminately – muscle, bone, fat and organ tissue, or do we want to lose fat exclusively? To lose fat exclusively, we want to create a small caloric deficit while strength-training to ensure muscle gain. Too big of a deficit will lead to loss of fat, muscle, bone, and organ tissue – recommended only if you enjoy frailty and looking and feeling like a zombie!
3. I eat very well, and I like to eat whatever I want, so I don’t want to change what I’m eating or reduce my calories that much
HUH? You may not be psychologically prepared to make a real and lasting course change. You may wish for less body fat, but you haven’t really decided to modify your diet. Don’t worry, when you are serious about dropping fat, it’s easy. The decision to eat somewhat fewer calories is a small change that’s easy to maintain. Often, when making better nutritional choices, you can actually eat more and still reduce calories! Plus, with healthier choices you can pretty much say good-bye to mood swings, drops in energy throughout the day, and many digestive troubles.
4. What else can I do besides reducing calories?
HELLO! Refer to the earlier parts of this series. Rev-up your resting metabolism by adding lean muscle tissue, stay pre-occupied with mindful activities, and if you do develop a craving, get up and clean the house, throw a ball to your kids, walk the dog, or wash the car. These activities won’t burn a lot of extra calories, but they will help depress your appetite, diminish your craving, keep you pre-occupied, plus you’ll score big points with your loved ones.
5. I know, I’ll start ______________ (insert any “cardio” activity here)
Unless “cardio activity x” really is what you love doing, NOOOOOOOOOOOO!
Instead, do things that need doing or things that you enjoy doing. I recommend that you read the first several chapters of The Cardio-Free Diet by Jim Karas to convince yourself to give-up trying to lose weight by burning-up additional calories with time-consuming “cardio” routines. Karas writes, “Cardio kills your weight-loss plan, your joints, your immune system, your body composition, your time, and most of all, your motivation to stay committed to losing weight. But there’s one thing cardio doesn’t kill: your appetite.” We have a copy of his book in our mini library; feel free to borrow it any time.
The Mayo Clinic agrees, “[t]he key to weight loss is burning more calories than you consume. Because 3,500 calories equals about 1 pound (0.45 kilogram) of fat, you need to burn 3,500 calories more than you take in to lose 1 pound. So if you cut 500 calories from your diet each day, you’d lose about 1 pound a week (500 calories x 7 days = 3,500 calories).”
If you’re building muscle while modestly reducing your caloric intake, you can be sure you’re losing fat! There you have it folks, working and building your muscles is the role of exercise in fat loss.
