I wanted to share my personal experiences as well as go into discussion with you about similar experiences. I started out with 80-10-10 on February this year, but WITH calorie restrictions. This worked fine in the beginning and brought me down to ~ 9% bodyfat. Then I wanted to go even lower by lowering my calorie intake... and my mind just sent me from one cheat meal to another. So I ended with a little eating disorder because I always wanted to control calories, and then cheated and then tried to go back and so on.
After I gained back every fat that I initially lost, I decided to go for 80-10-10 unrestricted. I made that switch 18 days ago. With muscle gain as my workout focus, I consume about 4000 to 5000 calories each day. I make Datorade for breakfast with 1500 to 2000 cals depending on the timeframe when I'll be able to eat again.
Last weekend, my body requested for a huge amount of carbs. I drank Datorade for breakfast (1500 cals), 2 hours later I was hungry and my brother cooked some spaghetti with tomato sauce without any oil. Although cooked, I ate like 300 grams spaghetti. Still hungry. So I ate half of a vegan bread (made with 2 table-spoons of oil). In the evening hunger hit me again. Now I ate 500 grams of pure spaghetti - no sauce, nothing, just the pasta. I think I ended up around 6000 or 7000 cals this day. It felt like my body needed the assurance that the "starvation period" is over. Once and forever. I would have gone for bananas and apples instead of bread and spaghetti but I had no ripe bananas and i was running out of dates.
Trying to fall asleep that night I noticed that my body was producing massive amounts of heat. I literally had to remove all blankets in order to rest and sleep. So I was very happy because I thought that this is proof that excess calories are burned off as heat.
The funny thing is, although I consume that much calories, at least I don't gain in body fat percentages. My caliper still shows 13-14% bodyfat.
I workout 4 times a week by weight lifting in order to gain muscle mass. I plan to include endurance training during the 3 other days in the week. With that in mind, I really like the "no calorie restriction" mode because that ensures, I get enough calories in order to build up muscles. By the way - I will proof to you that getting huge on 80-10-10 is just a matter of intense weight training. And I work together with my friend Karl Ess, who really knows how to build muscle www.KARL-ESS.com.
However, I wonder how long will it take for my body to switch over to fat loss. Basically I am waiting for the first drop that I can measure with my skinfold body fat caliper.
Is there any logical explanation that can detail the process of the body losing fat?
Being an athlete I know how fat loss works in the calorie restriction mode from a biological standpoint. However, I am interested in the "no calorie restriction" mode for fat loss.
I'll keep you posted,
