I'll formally address this to Paul Mcglothin, but please jump in if you have something to add.
I have a question for you all if you're in the helping mood
My question is pretty straight forward: I'm a pretty large muscular guy who is looking to do CR without losing the lean mass that I currently have. I just got my stats done:
Weight: 245 lbs
Body Fat %: 17% (204lbs of lean mass, 41 lbs of fat)
Resting Metabolic Rate : 2600 KCAL/d (Putting my metabolism at ~3500KCAL/day with normal activity added in)
My plan to date is as follows:
1. Select a target calorie intake: For me, I was thinking 2800 which should put me at a 700+ calorie deficit (the + being exercise)
2. Practice the CRON diet and do high intensity strength training (monitor weight and BF%)
3. Once my BF% gets to ~8-9% i want to keep eating the same kind of food, but increase my calories to maintain this weight (rather than stay hypocaloric and start burning off lean mass)
- I also got my full blood work done, so that I can post a before and after. (Areas that i need to improve are triglycerides and HDL)
I am pretty sure that the above can be done rather easily: I can easily change my diet and shed some weight. My question is will this activate CR?
Now I have been thinking about this extensively the past few months and reading anything that I could get my hands on. What has really interested me is research done on 'set points' and the metabolic regulators of the body and adipose tissue storage.
Long story short, everything that I was reading suggested that the body has a weight that it 'likes'. When we drop below that weight the body will lower energy expenditure by improving metabolic efficiency, lowering body temperature etc.. Additionally it will make the brain/body more hungry for some time. This seems very consistent with CR. There have also been studies that show that people who have lost significant weight maintain this 'efficient metabolism' months after having lost the weight (much to the dismay of the participants in that weight loss study). This indicates that the metabolic shift that took place once calories were reduced persisted even though the weight of the participants stabilized at a lower point. If this is true and that metabolic shift was CR, then might it also be true that my above steps 1-3 could activate CR while keeping my lean mass? If no then will I need to further reduce my calories since my metabolism would have dropped from losing that lean mass?
I have been preparing for this little experiment for a while by gaining some good muscle mass. I am pulling the trigger on the CR part today, so I will firstly keep you posted and look to modify what I am doing based on feedback. Thanks!
