In general terms the lack of appetite would refer to toxicity of the liver... the possibility exists that you are simply bloated. I beleive that the body trys to sequester the toxins resulting in weight gain.
I would suspect that since Miracle-Mineral-Supplement is an oxidizer both of pathogenic guys and metals and other toxins that you may be burdening your liver with these things.
Do a long term liver cleanse of herbals (I use buplernum (sic) combination and have found it effective) tapping on the acupuncture points for the liver or using an electro stimulator would help open that channel. Other suggestions would be using methionine, cysteine or NAC, and taurine with adequate b12 and folic acid (folicin) would help the body clear the liver toxicity.
I also am a big fan of charcoal you can see tom harrelson for his excellent resources on activated charcoal and he has great prices on it as well.
Drinking lots of water, using anti oxidants such as Vit C (ascorbates) will help the body reduce toxic loads. There are many other choices as well such as rosemary that you can buy in bulk and grind in the coffee grinder that provides excellent anti oxidant ammunition. basically any fruit/veg and most herbs and spices provide anti oxidants.
