I gonna plead the fifth on the first two sources-they were put out by supplement companies...and the second one is specifically on capsicum as a supplement, not as a food component.

the third one talks about dietary red pepper as a carbohydrate oxidizing enhancer...fromthat perspective, red pepper CAN temporarily boost the "metabolism", or at least give the appearance of such, but it does not talk about how the "metabolism" slows down DRAMATICALLY about 30 minutes after consumption.

EAT spicey foods. they taste good and are good for you.[for other easons other than the "speeds up metabolism and then you lose weight" falacy]

if you want to lose weight, eat whole unprocessed grains, fresh roots and greenleafy vegetables, beans, herbs, spices, and lean high quality animal protien if you want.

I am a practicing Holistic nutritionist and I have worked with well over 100 people in the past 2 years or so. and all of my clients have lost weight and improved health in the same way I have just mentioned.

there is no single cure all for weight loss. it takes work and commitment. spicey food is not the answer...its only one smaill part of it...
