Milk while cutting

[Anakin]

Is there anything wrong with having milk while trying to lose fat?

Most people complain about lactose because it's a type of "sugar", but does it really matter as long as you keep total carbs and total calories to a reasonable level???

Lactose is very low-Gi, but replentishes mainly liver glycogen stores.

Make your own conclusion from that.

From a pure macronutrient/caloric effect standpoint milk is fine. Keep in mind, though, that a very large percentage of the population has an allergy type sensitivity to milk (not necessarily full out lactose intolerance).

One of the common symptoms of this "milk sensitivity" is bloat. You may be cutting fat just fine, but milk MAY make you look very smooth.

I love milk and I have to have it!!!!

Thanks.
I have taken 1 gallon of milk per day before so I'm not lactose intolerant. It does get me a little bloated but I don't mind that as long as the fat is dropping.
Ohashi, what do you mean it mainly replenishes liver glycogen? How can it have that "selective" effect?

 

[ohashi]

Lactose is composed of glucose and galactose (mainly galactose, I believe). Galactose, like fructose, replentishes liver glycogen, not muscle glycogen. I'm not sure of the actualy mechanics of this, but that's the way it works. I'm sure someone can explain the how and the why.

Ohashi -

lactose is a one-to-one disaccharide composed of glucose and galactose.

Galactose is metabolically suited to modification and storage more than it is to direct oxidation (as is the case with glucose). Check out an introductory biochemistry textbook, and look at the processes of glycogenesis vs. glycogenolysis, glycolysis vs. gluconeogenesis, and the citric acid cycle (Krebs Cycle, tricarboxylic acid cycle).

I have zero background on chemistry.

During fat loss, what is better? Carbs for storage or direct oxidation? Lactose good or bad?

My intuition tells me that replenishing muscle glycogen is desirable to avoid losing muscle...

wouldn't having liver glycogen stores full keep thyroid output at your normal levesl?

Thanks, but that basically made my head hurt.
