after the first few days without eating normal/cooked food it became easier per say, as cravings went down and your body goes into fast mode, even when consuming raw spirulina. i found weekends to be tough as you tend to go out more, and ads are everywhere for food.
also, after the second day you really start to shed water weight and your caloric intake dips into the negatives, as spirulina has about 10 calories per serving which is about 3g. i took an average about 30-60 tablets a day, roughly 2/3g (4-6 tabs) per doze. you drink a lot of water (which you should be doing anyway) m-f was easier for me as you're busy with work when compared to the weekends.
it was asked, how will we know if i'm honest and actually don't eat? we decided on the honor system and we did the math, loosely. in 14 days i should lose about 14lbs, at 1 pound /day, so i did a weigh in before and after. on the last day i weighed in and i did lose about a pound a day with a total of 14.6 lbs lost and i felt..good?/fine, lost weight, had new perspective at starvation, and food itself. you still should eat more than spirulina, which i did at 9pm that monday...green apples and raw chocolate bars were my choices :)
spirulina (cyanobacteria) gives you insane amounts of energy and contains a boat load of nutrients (rich in vitamin A (beta-carotene), B1, B2, B3, B6, E, and K). it also converts sunlight to protein more efficiently than any other living thing. it has the highest content of protein of any other food source around roughly (65-71%). its ancient food, and one of the important foods of the future. it along with other raw foods (fruits/veggies) IMHO is better for you than any other human made sludge/supplements. you can't beat real food and nature.
