Simple substitutions can add up big time in the long term.

SWITCH UP YOUR SOUP

Instead of dishing up a cup of cream of broccoli soup, which has 180 calories and 7 grams of fat, choose a bowl of chicken vegetable soup instead. You get just 75 calories and under 3 grams of fat for the same-size serving. Save 105 calories and 4 g of fat. Make this change once a week and cut out 5,460 calories a year, or roughly 1 1/2 pounds.

SUBSTITUTE YOUR SUB

A 6-inch meatball sub is 580 calories and 24 grams of fat; a turkey breast sub is only 280 calories and 3 grams of fat. Or take it a step further and opt for a veggie sub at just 230 calories and 3 grams of fat. Save up to 350 calories and 21 grams of fat. Make this change once a week and you’ll cut up to 18,200 calories a year, which equals more than 5 pounds.

INTERCHANGE YOUR DRESSING

Two tablespoons of ranch dressing racks up 140 calories and 16 grams of fat. Using a store-bought balsamic vinaigrette spritzer, on the other hand, packs a lot of flavor but only 1 calorie a squirt (10 calories for an individual-size salad), and only 1 gram of fat. Save 130 calories and 15 g of fat. Make this change three times a week and you’ll cut out more than 20,000 calories a year, which is almost 6 pounds.

EAT POPCORN

Tame your munchies with popcorn instead of potato chips. A one-ounce snack-size bag of chips has 150 calories and 10 grams of fat. Swap that for a cup of air-popped popcorn at 31 calories and 0 grams of fat. For a flavor boost, spritz popcorn with butter-flavored spray (0 calories) and toss in a tablespoon of grated Parmesan cheese (27 calories). Save up to 119 calories and 10 grams of fat. Make this change once a week and you’ll cut out 6,188 calories a year — that’s almost 2 pounds.

DROP THE SODA

One 12-ounce can of Coca-Cola has 140 calories, all of it from refined sugars that are pure trouble for people with diabetes. Replace it with a glass of ice water (0 calories) — add a squeeze of lemon, cucumber slices, or mint leaves for a nice refreshing flavor. Save 140 calories. Make this change once a day and you’ll slash 51,100 calories a year, which adds up to more than 14 pounds.

LIGHTEN YOUR LIQUOR

Instead of regular beer, which has 150 calories per bottle, opt for its lighter version at less than 100 calories. And instead of a 5-ounce glass of Pinot Grigio at 120 calories, cut the calories in half by making a wine spritzer instead. To make: Combine equal parts wine and seltzer. Save 50 to 60 calories per drink. Make this change once a week and you will cut out 2,600 to 3,120 calories a year, which could equal almost a pound.

TRY NATURAL SWEETS

Craving dessert? Rather than reaching for 1 cup of premium strawberry ice cream at 500 calories and 16 grams of fat, opt for 1 cup of strawberries at 56 calories. Still want something creamy? Even 1/4 cup of light whipped cream (the kind in a can) adds only an extra 30 calories and 2 grams of fat. Save up to 444 calories and 16 grams of fat. Make this change twice a week and you will cut out more than 46,000 calories a year, which adds up to more than 13 pounds.

SKIP A YOLK

Nix just 1 yolk from meals that require 2 eggs (think omelets). A whole egg has 75 calories, but there are only 16 calories in the white, and no fat. Never removed a yolk from the white? Buy an egg separator—they cost next to nothing; find them at any store that carries cooking supplies. Crack the raw egg and pour it into the separator; it holds the yolk while the white drips through. Save 59 calories and 5 grams of fat. Make this change twice a week and cut out 6,136 calories a year, which is approaching 2 pounds.

MAKE TOAST

Replace a bagel (354 calories) or bran muffin (410 calories) with 2 slices of whole-wheat toast (164 calories). Skip the butter (100 calories per tablespoon), and spread on 1/2 cup of fat-free cottage cheese (90 calories)—your calorie count is still lowered, and yet you still get lots of creamy flavor without all that fat. Save up to 246 calories. Make this change once a week and you’ll cut almost 12,800 calories a year—that’s more than 3 pounds.
