Fasting and paleo

When I was on my old way of eating (high-carb), I had extremely difficult time with any kind of fasting. When I tried to fast a whole day (for religious reasons, like Yom Kippur), it was a nightmare. Very soon after waking up I would already start to feel bad. A few hours later I would have no energy, had problems with moving my legs fast, my head would feel as if made of lead with pounding pain. Toward the end of the day I would be lightheaded, dizzy and sometimes close to fainting. I thought it was just my nature...

On Monday we had "Back to School Night" about which I completely forgot. It meant that instead of going home before 5pm I made it at 9pm. With no extra food, on some eggs, coffee with cream and protein shake. Hardly any hunger, no headache, energy and full mental attention.
I used to say how I simply couldn't not eat a breakfast. I would be sick and nauseated with this deep, painful need to eat at that right moment. Nothing like that anymore - when I am hungry, it's a normal signal, no attack from inside. It's fascinating to me how all of that has changed.

Yesterday I did my "refeed" dinner. And I had too much. I see on other blogs how people make these humongous meals, sometimes calling them variations of "refeeds". How do they do it? I tried three beef sausages, three eggs with two extra yolks and a bit of veggies (broccoli, green beans, mushrooms). I felt full one third in. I wasn't sure if I should just stop or try and force to eat more. I decided to try and it more, because I don't want my body to think I am starving it, so it would go into starvation mode or something.

Each day this week I came back late from work, so no workout yet. And tomorrow I will be even later... Friday it will be, then. And maybe Saturday as well. I have to do a good strength workout and practice more on pull up bar. I am beginning to being able to do pull up! I have big problems with that... I try with support, and it gets better. chin ups get better as well, now I can do 3-4, and same with parallel chin ups.

"healthy" knish

In the faculty lounge during lunch we often comment on each other's choices of food, exchanging ideas and sharing struggles (a few people try to lose weight). Today the hero of the hour (well, 20min) was home made knish. It looked very good, had no crust and according to the maker was also delicious. The person got the recipe from cardiologist which in the opinion of all present gave it a stamp of approval. Everyone assumed it must be healthy... I said nothing when I started to hear the ingredients... Apart from spinach and spices I wouldn't touch anything else in it. Egg beaters? Tofu? fat free mozzarella? Sad. I didn't say anything because I knew it was pointless. Between weight watcher, newborn conventional (fat is evil) healthy eater, cancer survivor on low-fat "healthy" diet and a couple others SADers* there was no point. It would only upset everyone, especially that most of them really think they know best. Obviously I also think I know best :) The only reason I feel better is that I have been researching nutrition and evolutionary science for quite a while now and don't take my health advice from color magazines.

I have decided to give PSMF** a try. Even though I didn't get into paleo in order to lose weight, I do want to shed the waist and legs/buttocks fat that I put on about a year ago. I switched then to a new anti-anxiety medicine and it caused enormous carbs cravings, no control in eating sweets and cakes, and made me 30Ibs heavier a month and a half later. I would like to get back to my wardrobe from the days before that.

I let myself eat too much of healthy and  paleo foods. I forgot that paleo means also eating according to the body's needs. Which means I should eat when I am hungry and enough to be satiated, not because I feel like it would be fun to eat a bowl of sour cream with coconut and banana. I think it is clear what I am talking about ;-)
So for a few days I am trying to keep on the low carbs but also cut on fat, with the minimum protein that is needed per day. This way the body is not starved, receives enough necessary nutrients but also is prompted to kick in serious fat burning. I will let you know how it goes - it's only day two.

**PSMF - Protein Sparing Modified Fast

fasted training

Once in a while I workout when I am hungry, or on really empty stomach (but not feeling any hunger at the moment). Since going paleo I can fast hours and feel ok, with a lot of energy and no touch of the old nausea as I used to have on old carb-focused diet. Most of the time I don't even plan on fasting (even though a lot of paleo do it for health reasons), it just happens - I forget to take lunch with me, or don't eat breakfast etc. There are many studies that show benefits of hunger and fasted state for human organism. Some hormones work better, the body has a chance to cleanse a bit, get a breath, strike a balance. If you workout when hungry, which was very common for paleolithic peoples (workout = hunting/gathering/escaping/building), your growth hormone is released, insulin sensitivity improves , and it's even more easy for you body to use fat as your fuel.

In this blog entry there is even more explanation on the benefits, with links to some new studies. Here is just a small excerpt:

As you can see, the fasted training group beat the fed training group on almost all relevant parameters. More importantly for some perhaps, the fasted training group saw significant improvements in all parameters relevant to improving body composition and health, where as the fed training group saw comparatively lackluster results here.

This study strengthens the notions I covered here, which is that fasted training may provide some unique benefits to those training in the fasted state, whether it be endurance training, conditioning or bodybuilding. However, this study may be somewhat more relevant considering the higher exercise intensity used, which is closer to, albeit not exactly similar, to CrossFit, kettlebell training and weight training. That is, activities which rely on glucose utilization to a greater degree than fat oxidation.
