I'm having a hard time understanding why that would happen. It's just oil. I go to Italian restaurants and dip my bread in oil. I have cooked with oil. I've eaten fried foods. I'm not doubting you at all, I just don't understand how a food item that's a normal part of most people's diets could cause lethargy when consumed alone.
Gastric upset I can understand and have had. I'll try fiber caplets, thanks!
It makes sense to me that there would be some lethargy from taking the oil. Granted, we don't get these side effects when we consume it with other foods, but I doubt there's much of an occasion where we would actually eat 1-2 tbsps at a time. I would wonder too, if the effects of the oil on its own in our systems would be more pronounced than when its in our gut with other foods that are more easily digestible. One of the reasons that i think this diet works is that fat (oil) is digested slowly, and is thus likely to slow us down a bit. Because it is digested slowly, it is also known to make you feel full longer.
I just started yesterday, taking 2 tbsps 2x day. I slipped up a bit last night, had water with a lemon in it 45 mins post-oil. hopefully that won't interfere much. the IDEA of taking the oil i find hard to deal with, and the immediate aftertaste is also a bit tough, but a few seconds later its fine. I'm not sure how i feel its going yet. i'll give it a few more days and see where my hunger is at.
