Question Caloric Restriction - Pros and Cons ?

Something has been nagging at me as I Crossfit and quickly approach the best shape of my life. I am on a rather strict Paleo diet, and trying to cut down on my body fat. I am 74" 197lbs. and sitting at right about 12% body fat, and eat anywhere from 1800 to 2600 calories a day. From what I have read and know from personal experience, fat loss is simple math. More Calories out than in.

The way I see it i probably burn around 1800 callories a day just being alive. With this being said, combined with working out, i would obvisouly be burning more. While i want to loose fat by creating this deficit (eating <2000 Cal. a day) i feel weak and not nearly as able to push myself on the WOD. Is that normal? I've been trying for a couple months to find a "sweet spot" and have as of yet been unable to.

Am i doomed to being uncomfortably fatigued during workouts from creating this deficit for wanting to burn fat? What are some other options?

Thanks for any help

Re: Caloric Restriction - Pros and Cons ?

I'm 5'10" 180. I eat 3000 to 3500 calories a day, avoiding processed sugar. Since I started crossfit 5 weeks ago I've lost about 1 pound a week while gaing a ton of strength (and considerable muscle mass) and endurance. I'm never hungry (I don't allow it), and rarely tired despite 5-6 hours sleep a night. When I don't eat enough my intensity during workouts suffers.

I wrestled for many years (not recently or I wouold weigh 180), so I have experience with caloric restriction and cutting weight. It sucks. I can't imagine under-eating without the pressure of making weight, especially knowing its adverse effect on performance and that I can lose weight without starving myself. I think a deficit of more than 5% is not a great idea. Good luck.

WRONG

Not to be to harsh, but that is simply not correct, I started a thread after watching the link posted above and in the first post discuss how that simple math equation is very missunderstood! here is a link to the thread:
http://board.crossfit.com/showthread.php?t=30900

check it out, also watch the video, it is very informative and usefull

End result it is WHAT you eat, not how much of it you eat

Actually as always the result is a combination of both. Taubes has it only partially right. He oversimplifies. Eades addresses this on his blog somewhere. A calorific deficit is required. It's just easier to do on a low carb diet because of the insulin blunting effect.

The Zone is basically a reduced carb, calorifically restricted diet. It's the combination of both factors that make it successfull for fat loss.

Re: Caloric Restriction - Pros and Cons ?

the Zone has you eating 40% of your dietary calories from carbs, i would not call that a carb restricted diet...
and it is saying you must have a caloric deficit that is oversimplified and missunderstood, how do you think people starve to death while getting fatter?? i suggest reading the post i linked too, it explains more clearly than i care to here

Re: Caloric Restriction - Pros and Cons ?

A caloric deficit is the only way one is going to lose weight. It's possible to recomp while not being in a big deficit, but if someone maintains their current weight on 2,700 calories a day (after activity figured in) they will sure as hell not lose weight eating 2,900 calories.

The deficit can be induced via calorie restriction or via activity, but a deficit is still needed.

It's carb restricted compared the the RDA recommendations, as well as compared to the typical American/Western diet. I do believe you have to have a defecit, as I notice that when I eat more than about 2400 calories a day my weight loss stops (even though it's all good, clean food). Under that and my weight loss is steady at about a 1 - 1.5 pounds a week. I'm 5'10", 205, 18% body fat. I try to eat Zone ratios as well. There's no way I could eat 3500 calories a day of Paleo/Zone and continue to lose weight, I know this for a fact.

EDIT: I also have not suffered in my WODs, although I've been cutting fat the whole time I've been CFing, so I don't have much to compare it to. I feel strong, not tired, it's my cardio that's the worst, but that's always been the case.

It is restricting you to 40% total carbs as well as restricting your total calorie intake using the block count, so yes definitely restricted.

Could you point me to a link on some one starving to death while getting fatter. Malnutrition and starvation are two different things.

I've watched the lecture. Some good stuff but as I said over simplified. Eat 7000 kcal of lard and report back on your weight loss.
