I've started taking a bit of whey over the past 10 days, usually a scoop (20g) of whey isolate with added lactoferrin (50 mg) from LEF. The lactoferrin is in the apolactoferrin form, so it scrounges up iron in the gut, which may reduce the number of gut pathogens as their growth is iron limited, LEF claims. The only other change I've made to my supplement regime is to use LEF's curcumin product (the one that doesn't use piperine).
I lost 6-7 pounds in this period, which surprised me. I'm only at 140 pounds now, and my BMI is about 21.5, a drop of about 2 points. Anyone else seen this type of weight loss on either whey or lactoferrin?
I've read somewhere else that a study examined the gut bacteria of a variety of people overweight and not, and they found that the bacteria in an overweight person was different in a normal weight person, and that the types of bacteria in dieters change as they loose weight. Here's one New Scientist article that talks about gut bacteria and weight.
In a second New Scientist article, I read
The amount of weight an animal gains from eating depends partly on the types of microbes found in its gut, a new mouse study reveals.
I am wondering whether the kind of bacteria that increase calorie absorption from food are also the ones that need the iron that the apolactoferrin binds.
