No, I’m saying b/c of the extremely low calories required by the v-diet, and yes I’ve completed the v-diet, coupled with the huge expenditures of your training, you WILL lose muscle. You don’t have to believe me or you can hate me, but go ahead and try it and see if I’m right.
With your kind of activity level and some sort of smart eating plan, perhaps such as the anabolic diet, you could lose LOADS of fat without your training suffering.
How many times a week are you gonna do the 9 mile? My suggestion would be pick a high fat, low carb, mod/high protein diet, (such as T-dwag or AD) that includes a weekend carb-up.
Plan your longest runs for the day of the carb up and maybe 2 days after it, or the day before and the day after or something like that, then do your other runs during the week while you are low carbing.
The weekend carbs will refill you glycogen to help with your long runs. And the high fat during the week will spare your muscle because it won’t be converting all your protein to glucose via glucogenesis for energy.
Basically, your week day energy would come from high fat, and you insulin and blood sugar will be controlled from low carbs. The protein will be used for muscle repair.
On the weekends and the couple days following your carb ups, you will feel more energized and will have better endurance for your longest runs if you plan them around the carb ups.
If you followed something like that with you activity level I’d bet money that fat will melt off you right before your very eyes. The difference is your muscle will be saved because fat will be fueling you, not protein.
On a low fat and carb diet like the V-diet. Will all your energy expenditure, your protein will likely be converted to glucose for energy which means your muscles will be deprived of protein and will not be repairing and therefore will be dissapearing.
High fat/low carb diets are muscle and protein sparing.
Low fat/low carb (the v-diet), coupled with as much activity as you will be doing will be a recipe for muscular loss.
Does any of this make sense.
It’s coming from someone who has lost a shit-ton of weight, has completed the v-diet, and has lost muscle at times dieting while also has maintained muscle at times while dieting. I have a little experience in this area.
