Has anyone tried raspberry ketones for weight loss?

[shoppingbagsundereyes]

Am sick of slow slow slow weight loss. I've been on less than 1400 calories for the past week and have only shifted 1/2 lb this week. I've tried a range of diets and seem to just have slow metabolism. So I've bought a pot of raspberry ketones tablets which are supposed to help speed up metabolism and shift weight a little faster. Wonder if anyone has had any success with these?

I haven't but watching with interest. Where did you get the pills from?

Amazon but holland and Barrett sell them too. Totally natural ingredients except for caffeine but I don't drink any caffeine at all so I figure the amount in the tablets will be ok. 5 days in and no side effects. Scales say 2lb off this morning - I've had under 1500 cals each day since Monday. Suppose that's not bad, was hoping for 3 or 4 but I've never managed to shift more than 2 in a week whatever diet I've tried. Have got over 2 stone to lose.
