Not me, though - I do not like coffee, Sam I am. No, I don’t even like green eggs and ham.
Anyway, the good news for those who like coffee - and caffeine in moderation is:
CAFFEINE
What it is: The wake-you-up chemical in your coffee appears to be the most effective weight-loss ingredient. (Health.com: Your vitamin cheat sheet.
Why try it: A stimulant, caffeine speeds up metabolism and can ward off listlessness from dieting. It may suppress appetite, too, and boost the power of other weight-loss ingredients.
Why not: More than 400 milligrams per day (equivalent to three to four cups of coffee) won’t help you lose more weight and could bring on jitteriness, headaches, and insomnia. Unfortunately, most products don’t reveal their caffeine quantities in easy-to-understand terms; a typical daily dosage of some supplements might have as much caffeine as 30 cans of Coke (1,200-plus milligrams). Skip it if you have high blood pressure or heart disease, or if you’re pregnant or nursing.
This is from a Health magazine article posted on cnn.com. It talks about some other diet supplements as well - good and bad.
So I think I’ll keep enjoying my diet pop once a day. 
My husband claims that coffee suppress his appetite. But I have yet to experience that side effect. Wish it would work for me though. That would be nice.

My friend swears by paracetamol that contains caffeine (rather than paracetamol on its own), and gave me some to take in our first year at university. Lets just say I’m not allowed to take those tablets anymore (they sent me totally hyper!)
