Feeling peckish but don't want to derail your diet? Don't panic! Here are 100 nutritious snacks to satisfy even the most ravenous of appetites, and give your body a metabolising boost in the process. Contrary to what some diet programs suggest, snacking in between meals is an important weight loss aid, as it prevents overeating at meal times and encourages regular blood sugar levels, which will help you steadily burn calories throughout the day. Remember that women need to eat around 2,200 calories a day to maintain weight, and 1,750 calories a day to lose weight. Combine this with regular exercise and plenty of water, and you've got the dream formula.
