for a quick fix, try a detox diet. i know they are controversial, but its only for 2 days.
the one i use - day 1 eat only fruit, so like an orange for breakfast and then fruit salad for dinner and lunch (with a small amount of honey and yoghurt). then the second day eat fruit for breakfast then only salad for lunch and dinner with 50g of cheese and 50g of chicken breast. drink hot lemon water as soon as you get up, and then only water for the rest of the time. i think green tea is recommended too.
WARNING it makes you grumpy as hell! lol. i found i got headaches from not having caffeine, so i had a cup of coffee for breakfast too
basically you dont eat anything, and its supposed to detox your system. you could probably loose a couple of pounds from this, but itll be mostly water weight - then again that is good as it reduces bloating.
after that, reduce refined carbs an sugar and salt, and drink lots of water and green tea. and exercise!
i expect negs for this, but as i said - the detox is only for 2 days. do not do it for longer! its only a quick fix. y
