OK, I have a problem eating healthy food, and I’ve always had a problem (understatement) sticking to my ideal weight, but I’ve been drinking lots of water (probably more than 4 liters a day), and I feel great. Something as trivial as cutting back on soft drinks and increasing water (and fruit juice) consumption really does make a big difference.
