OK, so it’s been a whole week, and you’re hell-bent to stick to that New Year’s resolution to lose some weight. Calorie counting is the most obvious way to go when tracking your intake, but how do you know how much to buy of the foods you love and still stick to the diet?

WiseGeek gives you a visual cue, depicting a rainbow of foods measured out in 200-calorie increments. So if you have room for a 200-calorie snack, you can munch on a forest of celery, four Tootsie Pops, a hotdog and change or a wee snort of Bailey’s. It’s a great reference when bulding your next grocery shopping list.
