I've been an athlete all my life, and an avid mountain biker into my late 40's. At 5'10", my weight has slowly crept up over the years from 175 in my early 20's, to 185 in my late 20's, 200-220 in my 30's, 230's into my 40's, then last Christmas I found myself at 240 at 47 yrs old.
Mountain biking and going to the gym in general were downright humiliating at 240 pounds. I had lost my Mojo.
I saw a friend have incredible results on the Ideal Protein diet protocol, a low carb ketosis based-reset the pancreas type diet, so i researched it and signed up.
I lost 40 pounds in 10 weeks by June 1. I did not excercise at all during that time and followed the protocol pretty closely, with a cheat here and there.
Summertime means mountain biking so I got out the bike expecting to still be out of shape and boy was I suprised. Ideal Protein had been a fountain of youth, bringing my mountain bike levels back to when i was 10 years younger. No more lactic acid build up on the uphill sprints, much more stamina overall, and now instead of the last one up the mountain, I am first by far out of my main riding group. The change from recent years is nothing shy of awesome.
Now, an agressive 3 hr ride with lots of elevation gain is the norm. I usually consume one snack bar during the ride (which normally, I would never thik is enough for a 3 hr ride), and three times I had Hammer Gel packs too. H2O in my hydration pack, with Crystal Light Energy Drink in a water bottle.
I'm getting out about 3-4 times/wk. Not to train, mind you; it's just fun to ride. And I tend to ride relatively hard.
I began lifting weights in the a.m. also. Just three days a week, light routines.
All is wonderful.
Except that in the following two months since resuming riding and weightlifting, (June & July) I've only lost 13 pounds. 53 pounds overall; 240 down to 187.
I really would like to get down to 175, or 180.
Ideal Protein has an Alternative Protocol for athletes, and my advisor has put me on this but it is too difficult for me to adhere to. For example, it states that a meal must be eaten a min of 2hrs before the morning work out, then a snack must also be eaten 20-30 min before that workout also. I need to be to the gym at 6am or it's not going to happen, so there is no way I am going to eat at 3:30 am. So I am just eating a snack bar before my morning weight routine.
So no, I am not following the exact Alternative Protocol for athletes.
Is this the real reason why I am not losing weight as rapidly as before I resumed exercising?
Is it becasue the first 40 was just easier to lose, and things slow down as your body...gets nearer to it's natural weight? (Does ketosis work like that?)
Is it because the (routinely) random handful or two of Wheat Chex I nab off my daughter's plate has a larger effect on my ketosis state at 190lbs than it did at 240?
I have actually had to cancel my last three appointments with my advisor to to emergency travel needs, so i have not adressed this with her yet, but am curious enough to post here about it.
I've seen posts that claim intense exercise creates cortisol which can inhibit ketosis, but I have not seen any other explanation of what/why/and how regarding cortisol, so...who knows?
Any comments would be greatly appreciated.
