Hello All,

Does anyone know how long it takes for someone to deplete all the glucose stuff (pardon me I don't know the correct terminology) and get to using up the stored fat energy (burning fat)?

Ive searched online and I've seen sooo much stuff but none of it is clear and some doesn't sound right at all lol.

I know all bodies are different but an estimate would help so that I can either stay at the rate I'm going or exercise longer to burn more fat.

Your body will use fat and glycogen in varying percentages all the time you are exercising. The higher the intensity the higher the percentage of glycogen. It's not a case of your body using all the glycogen and only then turning to burning the fat.

What exercising are you doing? What intensity are you exercising at?

This guy also believes you can get your body to burn a higher percentage of fat by eating foods that keep your blood sugar levels level ... in other words cutting out the sugar spikes. He believes that the sugar spikes hinder the fat burning process. I heard him on a Podcast and he made a lot of sense.

I do aerobic classes 3 times a week. 45mins each very high intensity (Kickboxing, Cardio Blast)

then I do weights twice a week, Lower (70lbs), upper (30-40lbs) And thats really heavy for me so I guess it would be high intensity and that usually takes 30minutes.

Then I do Running on the treadmill for 10minutes.
And walking at about 3.0 for about 30 minutes.
Then the elliptical at moderate intensity for 10 minutes.

So I either do weights then cardio
Or Aerobic classes (some include low intensity weights)
and more cardio after.

So, whats this I hear about after 20 minutes or 30minutes of moderate intensity working out the body starts targeting fat?

Oh okay
I think I need to stop listening to what people say around me and just know that as long as I am getting my exercise in and eating right results will come.

Sometimes I get so caught up in the mix but I am really busting my butt in the gym. I feel it when I wake up and soon the scale will show me the results I am looking for.

Thanks Mike!

What are people telling you?

I think the best type of exercise is the one that you enjoy and that you will keep doing. If you enjoy this routine then keep on keeping on.

What about your eating? I'm not a fan of counting calories but lots of people on here do (and post daily eatings) and it might work for you.

Well, there's this thing called a "myth"...

At the end of the day, as long as you've got a calorie deficit in the 0 to 600 calorie per day range, your body will tap into its fat stores to make up the difference.

If you actually burned off all your glycogen, you'd feel awful AND it would take forever. Your body stores about 1500 to 2000 calories worth when it's fully stocked (which actually makes your body burn fat more easily because you're muscles are happy and healthy and don't think you're starving to death).

It's true that at lower intensity, a great percentage of your calorie burn at that moment is fueled by fat, but a higher intensity burns more calories total. Over the course of a week it doesn't matter which source your body uses at the time.

I wrote a big chart/graph a while back here (about half-way down the page):

Mike,
Something about after I workout for more than 20 or 30 minutes then I am burning fat. But before then I don't burn fat just carbs? lol

I changed my eating drastically. On days I eat at resturants I count them on this app I have on my phone. But on other days I don't. I eat between 4-6 times a day, depending on when I wake up. I think I have the eating down for now (:

Tom,
Ahh, I can always count on you. lol.
So now it all makes sense.
I think I will stick to what I know and as long as I stick to the plan I will see the results like I have. It just takes time.
That chart really helped. Im going to review it more in depth.

Thanks a bunch!!!

I'd encourage you all to read this post/article and consider buying the book. I believe that conventional wisdom is flawed, and the sooner we all understand and accept that, the better off we'll be. Excessive amount of carbs are the primary driver for how people get fat, stay that way, and get fatter still. The vast majority of those excess carbs are not coming from fruits and vegetables. They are coming from sugar, processed foods, and grains. People aren't getting fat from eating fats.

I think a lot of people on this site have probably struggled with weight for a good portion of their lives. They may have had some success, and then gained it all back again, plus more. Maybe it's time to consider really changing what you do and having permanent success.

Anyway, here's the link.

Very interesting, Justa!

I tried, in different ways - the original Atkins diet, using the 'ketosis' sticks, clean eating, which came down to fruit and vegetables as the main carb source (everything organic to boot) but you know what?
Somehow, some way, even though it worked and I felt great and everything...I couldn't keep it up.

Those taste buds always trip me up...bad carbs are sooo good, so satisfying on a certain level...I know it's emotional but that doesn't make it easier to resist!

Still trying to find a working compromise!

I have a hard time sticking with planned diets too. It's not that it's hard, I feel they are limited and boring. I just try to keep the 'white stuff' limited in my diet.

@Nancy: Here's the way my doc explained it: When your body looks for energy, it seeks carbs first because they're the easiest to break down. After it burns the carbs, it is forced to look to fat stores for energy. For the first 40 minutes of your workout, you're burning carbs. It's only after those 40 minutes that you'll start working on our fat stores.

Food for thought: if you don't eat carbs, your body is forced to tap into its fat stores for energy.

I started the Atkins program about two months ago and for the first week I had trouble completing my workouts. I was told that I needed to increase my carb intake in order to run. What I found is that even though I'm only eating 25 grams of carbs/day (12-15 grams from green leafy veggies), I can run for an hour with no problem. I have no doubt that my body is using its fat stores for energy.

I hope this helps.
