How to utilize a Cyclical Ketogenic Diet for Physically Demanding Work 7 days a week?

I will be working in a very physically demanding job on a Canadian Oil Pipeline which may use up my glycogen stores daily. My question is what is a good macro ratio to have on a ketogenic diet before and after work so I can stay optimally fueled throughout my 10 hours per day of work and avoid the hunger pains of a high carb or high protein diet, does this describe a cyclical ketogenic diet?? Is it possible to eat only 2 meals a day and achieve optimal performance? I'm currently in a heavy ketosis state.
I'm going to be working 7 days a week for 10 hours per day. 

Nothing worse than having to depend on stimulants for energy.

There is a really good article about this here:



Basically, you can eat carbs and remain ketotic during prolonged periods of exercise. Although you may have to fine tune amounts and timings. Good luck.

You don't need carbs unless you're doing a ton of anaerobic exercise (fat is used in aerobic metabolism, which requires oxygen). What this means is basically that, unless you doing a bunch of heavy lifting, you could do keto with no problem. Most likely you're not doing anything anaerobic (sprinting, very heavy lifting, high-intensity short burts exercises, etc.) but rather repetitive, moderate-intensity work.

This is the perfect kind of work for a keto diet since fat is utilized during this kind of physical activity (assuming glycogen stores are used up), which means that while being in ketosis you would never experience what is referred to as "hitting the wall" since you are burning fat to begin with so there is no "wall" to hit.

If you eat enough to meet your energy needs you should be fine. If you are doing physically strenous work, make sure to get enough protein to repair/build tissues and try to meet the rest of your calorie requirements with fat.

Physically demanding work means you'll need a lot more carbs in your diet, which sadly isn't ketogenic.  You could try consuming a lot more protein to allow them to convert to carbs, but that process is slightly toxic as it produces ammonia which then must be disposed of.


You could cycle fats in the morning, and carbs at night with a gap inbetween.  You could also get a large percentage of your fats from MCT oil which will convert to ketones, but you'll need some way to consume it slowly throughout the morning.
