I was given the following rule of thumb: 10% of the number of calories should be equal or more than the protein gr.   another words 190 calories should give you 19 grams or more.

I can't say how healthy Goji Berries are, but no matter how healthy they are, making a juice our of them is not healthy. I guarantee that whatever health benefits they have are greatly diminished or lost entirely once they are turned into a juice, and I'm not really sure why you aren't looking at buying actual Goji Berries if you want to try them. You can order them for numerous websites. I actually just ordered a small bag to add sparingly to my homemade trail mixes. Although I was pretty hesitant about it due to the amount of sugar in them. I'm not sure if I will get them again.

Shakes may leave you hungry and really not satisfied. 

You have your tool - the sleeve.. why not try good low carb diet - dense proteins, with some fat and some veggies..   go back to basics...

I am on a modified FODMAp/ SCD /SIBO diet. Low carbs. Something that works for me. 

Exhaustion may be related to many things- iron deficiencies, low B12, low D, low proteins, thyroid problems (i.e. due low iodine, selenium,etc) 

I had some of those in the past and got treatment for some (iron infusion,B12 shots )- and increased supplements for some.   Once i discontinued the foods I am allergic - intolerant to - even though I eat less proteins - my blood works shows higher levels. Same with iron. 

B12 - I need weekly B12 shots - and we are not sure why... but as long as my doc has no problem giving me the script - I just get them.. Most People need once a month.. if any.. but for me - that was not enough... 

 I do have Adrenal insufficiency... not only i need to make sure i supplement vitamins and minerals, but I also need to be on daily steroids replacement therapy...But even with the steroids - I know what I am late getting the B12 shot..

H.a.l.a. B. I want to thank you again for how extremely helpful you have been. I googled the SIBO Diet and found one that is a combination of SCD and FODMAP http://sibodietrecipes.com/the-sibo-diet/ -- this blog post includes a list of foods to eat and those to avoid. The more that I read about SIBO, the more it sounds like the cause underlying my health issues. I am going to make some modifications to that list, as there are things on it that I don't eat either because I know they upset my GI (almonds, dairy) or because I don't like them (meat, alcohol, etc). 

I've suffered from exhaustion. Have you found that to be related to SIBO?
