I don't know about the weight loss shakes but most protein based ones are good as a supplement when you're training rather than as an actual meal replacement.

Do you drink tea? I make a cuppa when I think I'm feeling hungry and that's usually enough to get me through. Drinking lots of water also helps. More often than not, we are actually thirsty not hungry.

Try and start the day with a good breakfast, it really does make a difference to your hunger and food choices throughout the day.

Eat like a king at breakfast, a commoner at lunch and a pauper at dinner
