Tons of info out there regarding fiber and vitamins/minerals in regards to this diet, beef specifically is absolutely loaded with tons of vitamins and minerals, it's literally the only food that a human can not only survive on but thrive on. Like I said theres people out there that have done this diet for 20 plus years, cured all kinds of ailments like autoimmune diseases, IBS, all kinds of issues. I'm just doing this as an expiriment. One thing I will say is I've had zero bloat, zero gas, my bowel movements are reagular and solid every single time, zero gut distress and again with zero fiber/zero carb. If you are interested in further info on this you need to look into this diet more and you'll find all these answers. Our ancestors were hunter gatherers and you can be sure as hell all they were eating was meat and ocassionally berries depending on the climate/season. They werent eating oats or brocoli or take physlium husk or fiberlyze. And I'm not doing this for fat loss at all, it's just happening effortlessly, yesterday I ate almost 4 pounds of beef and I woke up this morning leaner lol, it's really weird I'm trying to test my threshhold of how much I can eat and begin to get fat. Again I was initially going to do this for a month but since I'm enjoying this diet and the simplicity of it I'm going to go for 60 days.
You have to ask yourself, if it's good enough for 60 days, why not do it all of the time? If it's really the ideal diet, why not do it all of the time?
There's no doubt that low carb (or in your case zero carb), helps a person get leaner. As bodybuilders, we all pretty much learned this fact a long time ago. Leanest I ever got was following an Atkins style diet.
Anyone who needs to lose some weight can benefit from it. Of course, there's the inevitable yo-yo back up to where they were before, once they go back to how they ate before. Or even worse, if they binge eat after all the deprivation of carbs, they put on more weight.
Once at or near your ideal weight, I think it's best to find a diet that helps you stay around that weight (takes some time to figure out, as everybody is different).
Bottom line, eating just meat/animal protein will eventually catch up to you in a number of ways:
1. No fiber = disaster waiting to happen
2. No carbs = eventually, you will go nuts
3. No vitamins/enzymes from live food = just plain bad
Again, don't get me wrong, it will help you lean out, but it's no way to eat forever.
So is your goal to get even leaner, or just see how far you can go on it because you feel good (for now)?
