Hi, generally i eat gluten free and mostly protein. But i havent been much without carbs at all. Whenever ive tried to go meat and vegetable only, ive felt lethargy, weakness, dizziness, the need to sleep.
Today i started by eating raw only (some raw slices of mutton, some eggyolks in the morning, lemon juice and olive oil). At first i was feel ok and quite energetic, because at lunch i ate the same again, but then it felt like i couldnt do anything or concentrate on anything. I then cooked alittle bit of rice and had a bit of cooked mutton left i made for my bf, ate very little rice but mostly the cooked mutton. Then i felt muscle weakness everywhere and had to sleep for several hours.
Now im back up again, but still have a slight brainfog Cooked some eggwhites i had left, but wondering if going low carb was too soon?
I felt fine eating some potatoes yesterday. The cooked meat felt pretty heavy, but i never had that expeerience with cooked rice or potatoes. Is there room for leaving some rice or potato carbs in?
You are experiencing your conversion of burning carbohydrates over to burning fats and that takes a while for your body to manufacture the proper enzymes to burn fat.
Dr Michael Eades, author of "Protein Power" has posted:
You just have to power through so that your body knows you are serious about this low carb thing so it will adapt to burning fats.
Most everyone here has experienced this to some degree...some breeze through and some take a while.
People talk about a "carb flu" when one starts to go no-carb. It's essentially the period your body is taking to "switch fuels", from carbs to fats. This transition period is different for everyone, with some people experiencing a lot of the same things you are.
My main question is, are you getting enough fat? You have to eat a considerable amount more fat than when you were eating carbs, since fats are now your only energy source.
You could try measuring our all the carbs you eat, and start at 150g, and then decrease the amount week per week, until you get to the amount you want, although I would just go no, or less than 50g, right away. Going back to what I said earlier, you want to have your body transition into a different state, which is "ketosis". One way to get a faster transition is to eat a lot of Medium Chain Triglycerides (MCTs for short).
In short, "carb flu" is fairly common, and you might want to search around here about ketosis for more information.
Why do you think you need to eliminate carbs in the first place? Is it because you are trying to lose weight? Or is it because someone told you that Paleo is low carb?
For weight loss I can understand. However, Paleo is not necessarily a very low carb diet. Humans evolved the ability to eat and digest starches, and tubers have been part of the human diet for ages.
I only feel healthy with a significant amount of starch. I eat potatoes, sweet potatoes, jicama, taro, cassava, rutabagas, parsnip, daikon, beets, and so on. You can really have fun with root vegetables and tubers. Pair them with some fatty meat (or butter if so inclined) and you've got an extremely satisfying combination.
That is dependent wholly upon your goals and personal tolerances.
If you get gassy or gastrointestinal discomfort from starchy foods (even the "safe" rice/potatoes/bananas), chances are you might have some intolerances.
If you are considerably overweight, than you may have some insulin sensitivity that needs to be addressed.
In both of the above cases, I would say you need to give it a few weeks before introducing any carbohydrate. You may even feel like you don't need to reintroduce carbs after a few weeks - if you do it properly and don't skimp on the fats.
To be a little critical of the way you are currently eating... egg whites are pretty much nutritionally devoid with the exception of just protein. You need fats, and the more you eat during the onset, the faster your body will begin processing fats for energy. I don't know what kind of quantity you are eating the raw mutton in (I normally can't make myself eat more than an ounce or two unless it's prepared a certain way), but your answer is to eat more, and focus on fats.
