P.s.- and I hate to confuse you, but too much protein is metabolized in your body just like carbs, so try to up your fat intake (zero carbs) and decrease your protein (if you're eating copious amounts of meat/protien, I don't know what your macronutriant ratio looks like. If so, I could give you better advice.)

...have some carbs (in moderation) when the feeling strikes. Don't totally deprive yourself, or you will be a lot more likely to binge on carbs and/or abandon your diet all together. Breaking the carb/sugar addiction is hard, but it can be done. Best of luck to you!!

Sounds like your body is making the switch from sugar burning to fat burning; and yes, the transition can be miserable. I live on a low carb diet, so I am accustomed to burning fat now, but when I was a newbie, if I had an intense craving for carbs or felt "low energy" due to lack of carbs, I would indulge my craving and have something carby. Then, afterwards, I'd get right back on track with my low carb eating. A few days later, I may feel the need for carbs again, so I'd repeat the cycle. With time, those carb cravings and low energy bouts became less and less frequent. So, stick with it...

I second the potassium supplementation. Made a big difference for me the first time I went through "keto flu".

It probably has to do with the low-crab diet.

You say high protein, but you need to be eating a lot of fat. The body can't use protein as fuel, it's either carbs or fat, and if you're restricting carbs to only 20g per day you need to up your fat intake.

Also, lowering carb intake means you'll be losing a lot of water/water weight, you will need to increase the amounts of electrolytes you're getting. This is salt, potassium, calcium, and magnesium. So next time you eat a meal, make sure you add some extra salt. Eat foods high in the others, a good place to check - http://www.healthaliciousness.com/

And lastly, it will take time for your body to adjust from burning carbs for fuel to burning fat. Feeling like crap is actually a normal part of the process, it should last only a few days. I know for me it lasted less than a week. Just give it time, you'll start to feel better.

You're switching fuels from carbs to fats. You haven't built up the supply of enzymes you need to adequately process the fats, and so, you're short on energy. Also, your electrolyte minerals (sodium, potassium, magnesium, calcium) that create your body's electrical signals are likely depleted (a LC diet depletes water and water-based minerals). Here are some ideas to replace those minerals for the next two weeks:

  • Sodium: drink some salty broth, like beef/chicken boullion daily. Low carb diets deplete sodium a lot, so don't be afraid of salt. Get up to 4000 mg./day (5000 if you're working out a lot or have a physically-demanding job) from food and supplement sources.
  • Calcium: If your plan allows dairy, 2 oz. of cheddar cheese daily or 1 C of yogurt daily; you can also take a Cal-Mag supplement temporarily (read this article about the risks). I like the Pioneer brand, made from ground cow bones, because it has all the co-factors (e.g., silica and boron) required to assimilate calcium. Get up to 800 mg./day total from food and supplement sources.
  • Magnesium: Spinach, chia seeds, or a chelated magnesium supplement, e.g., magnesium glycinate (1000 mg.) + taurine (500 mg.). Get up to 800 mg./day (temporarily), but in the long run (say 3 months), get only half as much mag. as calcium.
  • Potassium: Low-Sodium V8 or potassium supplements. Get at least 2 mg of potassium/calorie you eat.

The transition symptoms shouldn't last for more than 2 weeks, if you're otherwise in good health. The complete adaptation process takes 4???6 weeks. If the "carb flu" lasts longer than 2 weeks, see a doctor.

Because you're doing it right.

For healthy individuals, it generally takes 8-10 days to fully adapt to ketogenesis, and the point at which you run out of glycogen and switch over to ketones is the 4th or 5th day.

You feel like crap because your body doesn't quite know what to do with ketones yet.

So basically, you're right on schedule. Stick it out, the energy comes back in another day or so.

Just give it time to work.

Personally I prefer a moderate carb diet, supplemented with coconut oil. It seems to work better for me than a VLCD.

You're entering Ketosis. Tough it out and it'll turn around in a day or two.

It can take a few weeks to fully adapt.
