I have been keto myself for almost 6 weeks now. What are your thoughts there? You can determine which keto-friendly foods contain polyunsaturated fats by checking the ultimate ketogenic food list in section 3 M of this guide; all of the foods that contain mostly polyunsaturated fats will be colored green and purple. The fact that the nutritional change from a hunter-gatherer diet to a carbohydrate-based diet has affected populations negatively has been revealed by archaeological findings in ancient Egyptian mummies, since tooth decay, cardiovascular disease and obesity were very frequent in those times. The best version of an observational study is a prospective cohort study, this is where rather than asking people to remember what they were eating ten years ago, you ask them what they eat now and at regular intervals and follow their progress for a number of years.
Plus I heard that 80 HCA wasn't actually legal or possible (I'm not an attorney or a doctorscientist, so don't quote me on that - just passing along what I heard) The best so far for actual weight loss for me plus no nausea has been Pure GCE (I ordered mine through the site 'bestgarciniacambogiapills' dot com. Again, if you don't mind the jitters and all that jazz, it may be worth your time to check out the LipoVida brand.
Otherwise, Pure GCE gets my vote. Good product except the product isn't the best.
