From Atkins and South Beach to Weight Watchers and veganism, there’s no weight loss plan I haven’t tried. My painful years of yo-yo dieting has taught me one powerful lesson: calories in + calories out = weight loss. As scientific and monotonous as it sounds, there’s no more effective way to make that scale move than to count calories.

While it seems overwhelming at first, after you start counting it quickly becomes second nature. You start to memorize your favorite foods and how much they deduct from your calorie bank.

To get you started on counting cals, here’s a peek at what 100, 200, and 300 calories really looks like . . .

What Does 100 Calories Look Like?

1 large apple
1 orange with 12 cashew nuts
1 100-calorie pack snack
3 cups of air-popped popcorn
1 cup of baby carrots with 2 tablespoons of hummus

What Does 200 Calories Look Like?

1 cup of non-fat greek yogurt with 1/2 cup of blueberries
1 cup of oatmeal with sliced bananas
Mixed vegetable salad with leafy greens and 3 ounces of fish
