Ok, but wont it get the fuel from the fat and foods you are eating, what will tell it to break down your bodys fat cells?
OMB, opinion?

Had some chicken and kawfee for breakfast.
before the last couple of weeks i never realised i can be an emo eater. so i started with the reboot but im gravitating more to paleo lately. just because of the better variety. and my love for dairy
so i must have had like 3/4 spoons of sugar for the week. but just when i have filter coffee. and this week i needed a bit of a jolt at work. ive migrated to sugarless rooibos. if i feel like bread (dont flame me) i limit it to 1 slice seedloaf or 2/3 slices of those small rye bread from ww.
i did succumb to an emo crappy meal this week. had a toasted cheese on seedloaf with a half portion chips. normally i enjoy it but since ive started this journey it tasted like crap. i had a wrap with steak, pesto, green salad and sour cream with beetroot on the side straight after that crappy meal. tasted much better and didnt leave me feeling guilty. i walked away from a macdonalds meal i have/still been craving. proud about that.
nutrition tables still have me a bit confused i must confess. i used to have mango and apple dried fruit but after reading the nutritional info im trying out some biltong. im also listening to recordings of tim noakes on ccfm. very insightful stuff.
im not sure of how much ill be losing this week but my relationship with food is getting better. and thats more important to me at the moment.
Yay! You sound like you're developing a better relationship with food. That's great![]()

Carbohydrates Are Preferred over Fats for Energy When Excess Carbohydrates Are Available.
When excess quantities of carbohydrates are available in the body, carbohydrates are used preferentially over triglycerides for energy.
There are several reasons for this “fat-sparing” effect of carbohydrates. One of the most important is the following:
The fats in adipose tissue cells are present in two forms: stored triglycerides and small quantities of free fatty acids. They are in constant equilibrium with each other.When excess quantities of a-glycerophosphate are present (which occurs when excess carbohydrates are available), the excess a-glycerophosphate binds the free fatty acids in the form of stored triglycerides. As a result, the equilibrium between free fatty acids and triglycerides shifts toward the stored triglycerides; consequently, only minute quantities of fatty acids are available to be used for energy. Because glycerophosphate is an important product of glucose metabolism, the availability of large amounts of glucose automatically inhibits the use of fatty acids for energy.
Second, when carbohydrates are available in excess, fatty acids are synthesized more rapidly than they are degraded. This effect is caused partially by the large quantities of acetyl-CoA formed from the carbohydrates and by the low concentration of free fatty acids in the adipose tissue, thus creating conditions appropriate for the conversion of acetyl-CoA into fatty acids. An even more important effect that promotes the conversion of carbohydrates to fats is the following:
The first step, which is the rate-limiting step, in the synthesis of fatty acids is carboxylation of acetyl-CoA to form malonyl-CoA. The rate of this reaction is controlled primarily by the enzyme acetyl-CoA carboxylase, the activity of which is accelerated in the presence of intermediates of the citric acid cycle.When excess carbohydrates are being used, these intermediates increase, automatically causing increased synthesis of fatty acids.
Thus, an excess of carbohydrates in the diet not only acts as a fat-sparer but also increases fat stores. In fact, all the excess carbohydrates not used for energy or stored in the small glycogen deposits of the body are converted to fat for storage.
Acceleration of Fat Utilization for Energy in the Absence of Carbohydrates.
All the fat-sparing effects of carbohydrates are lost and actually reversed when carbohydrates are not available. The equilibrium shifts in the opposite
direction, and fat is mobilized from the adipose cells and used for energy in place of carbohydrates. Also important are several hormonal changes that
take place to promote rapid fatty acid mobilization from adipose tissue. Among the most important of these is a marked decrease in pancreatic secretion of insulin caused by the absence of carbohydrates. This not only reduces the rate of glucose utilization by the tissues but also decreases fat storage, which further shifts the equilibrium in favor of fat metabolism in place of carbohydrates.
Are you in-between hangovers? Weekend coming up, pace yourself....
I'm sure Sinbad answered this the other day, anyway, I'll have a stab at a simple answer to what is actually a complex question...
the body processes fat differently to the way it processes carbs, please remember there are a whole host of hormones and enzymes involved in the breakdown of different food types into the energy components the body requires. Also remember that the body requires energy constantly, even when we are resting/sleeping the body still needs fuel to function so is constantly burning up whatever fuel is available.
So when we eat the body works with the fuel it has been provided, refined carbohydrates are quick fuel and easy for the body to use and insulin is the primary hormone involved in converting carbs to energy and storing away the excess for fuel later (your fat cells are almost like a savings account where your excess is put away for a rainy day). However, the raised levels of insulin also prevent the triglycerides that have been formed from being accessed as fuel later on (until such time as the insulin serum levels drop - usually when we are fasting i.e. asleep) However, with carb intake we have stored more than we need and with each carb intake we spike our insulin denying the body access to the stored energy and whilst the body will tap into the stored fat whilst we sleep, we've actually stored more than we need and so the cycle continues.
When we remove or significantly reduce carb intake our insulin levels can now correct and the body can access the stored fat, here's the trick though, if fat is the primary energy source the body has to work harder to convert it to energy, so our body works harder to digest dietary fat also because our insulin levels are lower it's far easier for the body to access the stored fat and convert it to the required energy it needs to function.
the body will self regulate quite efficiently once it's brought back into balance
here's the scientific explanation for googoodoll![]()
Just to add,
I have found that reducing my carb intake I have spontaneously reduced the amount of food that I eat. As soon as I get back into carbs I can eat tonnes more.
I find the same... I'm like a crackwhore when I eat refined carbs.
OMB, do you suggest cutting out carbs completely? Is fibre not critical for body function?

Let me rather put in perspective of my carb intake and my situation.
I am rather lean, I'd say between 10-11% BF, and I would like to reduce this to around 8%. Not in a hurry though as I would still like to build muscle while dropping the %BF.
I believe I am quite active. In the gym 5 times a week and between 40-50mins doing rather intense weight-orientated exercises.
My protein intake is very high: 2 eggs each day, some cheese, +-3 glasses of milk, 3 protein shake servings a day and 300g steak in the evening.
My only carb intake is in the morning when I have 3 Wheatbix bisquits, and two slices of low-gi whole wheat toast in the afternoon. (I might take some carbs in with my veggies in the evening as well which are those pre-freezed combo packs you buy at spar which contain beans, brocolli, cauliflower and a little bit of carrots...mostly brocolli and beans though)
I'll keep quiet on the dairy...
Do you really need 3 protein shakes???
And frozen veggies??
Leave the bread and provitas...
ok edit.. How the hell do you consume 3 glasses of milk a day???
