Military Diet Cheddar Cheese Alternatives: Swaps That Hit the Same Macros
One ounce of cheddar cheese appears at Day 3 breakfast of the military diet — alongside five saltine crackers and one medium apple. At 113 calories and 7 grams of protein with 9 grams of fat, it is the fat-and-protein anchor of Day 3's lightest meal, providing the satiety extension that makes the 273-calorie breakfast hold for a reasonable morning window.
Reasons to substitute are numerous: lactose intolerance (cheddar is lower in lactose than many cheeses but still contains some), dairy allergy, vegan diet, personal aversion to cheddar's flavor, or simply not having cheddar available when the diet starts. All are valid. The substitution requires matching the 113-calorie serving as closely as possible with a similar fat-and-protein profile, since the satiety function of cheddar at breakfast depends on its fat content specifically.
This guide covers eight tested alternatives — hard cheeses, soft cheeses, and dairy-free options — with complete calorie and macro data for each.
Cheddar Cheese at Day 3 Breakfast: What You Are Replacing
| Nutrient | Amount | Role in Military Diet Breakfast |
|---|---|---|
| Calories | 113 | Largest calorie item in Day 3 breakfast (41% of the meal) |
| Protein | 7g | Primary protein source for the meal |
| Total fat | 9g | Fat drives satiety and slows gastric emptying — critical for a 273-calorie breakfast to last until lunch |
| Saturated fat | 5.7g | Provides fat-soluble vitamin absorption support |
| Carbohydrates | 0.4g | Essentially zero-carb — balances the apple and crackers' carbohydrate load |
| Calcium | 202mg (20% DV) | Significant calcium source; may support fat metabolism per some research |
| Sodium | 176mg | Moderate; low-sodium cheddar reduces this significantly |
The most important nutritional properties to preserve in any cheddar substitute are the fat content (9g drives the satiety) and the calorie count (113 calories anchors the breakfast's total). Protein is secondary — 7 grams is modest and easier to match than the fat profile.
The 8 Best Cheddar Cheese Alternatives
| Substitute | Portion | Calories | Protein (g) | Fat (g) | Cal Match | Dairy-Free? | Flavor Profile | Rating |
|---|---|---|---|---|---|---|---|---|
| Swiss cheese | 1 oz (28g) | 106 | 8 | 8 | ★★★★★ Excellent | No | Mild, slightly sweet, nutty | ★★★★★ |
| Colby Jack | 1 oz (28g) | 110 | 7 | 9 | ★★★★★ Excellent | No | Mild, slightly tangy — very similar to cheddar | ★★★★★ |
| Gouda | 1 oz (28g) | 101 | 7 | 8 | ★★★★★ Excellent | No | Slightly sweet, smooth, buttery | ★★★★★ |
| Edam | 1 oz (28g) | 101 | 7 | 8 | ★★★★★ Excellent | No | Mild, slightly nutty — lower fat than cheddar | ★★★★★ |

| Mozzarella (part-skim) | 1.5 oz (42g) | 108 | 10 | 7 | ★★★★★ Excellent | No | Mild, milky, stretchy — very different texture | ★★★★ |
| Brie (soft ripened) | 1 oz (28g) | 95 | 6 | 8 | ★★★★ Good | No | Rich, creamy, earthy — very different from cheddar | ★★★★ |
| Vegan cheddar (cashew-based) | Portion to reach 113 cal | Match to 113 cal | Variable | Variable | ★★★ Variable | Yes | Varies by brand — check label | ★★★ |
The Best Everyday Substitutes
Swiss cheese (106 cal/oz): The single closest calorie match to cheddar of any common cheese at 1 ounce. Protein and fat profiles are nearly identical. The flavor is milder and slightly sweeter than cheddar — it pairs extremely well with apple slices, arguably better than cheddar does. This is the recommended first choice for anyone who simply needs a different cheese than cheddar.
Colby Jack (110 cal/oz): A hybrid of Colby and Monterey Jack that is essentially similar to mild cheddar in flavor and almost identical in calories. For people who find cheddar's sharpness too strong, Colby Jack provides the same functional role with a gentler flavor. Near-perfect substitute with no calorie adjustment needed.
Gouda (101 cal/oz): Slightly lower in calories per ounce than cheddar but within acceptable range. The slightly sweet, buttery quality of young Gouda makes the Day 3 breakfast feel more indulgent than cheddar does — the combination of young Gouda, crackers, and apple is genuinely excellent.
The Dairy-Free Challenge
Dairy-free cheddar alternatives present a significant calorie-matching challenge because they vary enormously in formulation. Some brands run 40 calories per ounce — less than half of cheddar's 113. Others approach 90 to 100 calories per ounce. Reading the specific product label before buying is essential.
For dairy-free dieters, the approach is: buy the vegan cheddar, read the nutrition label, and portion it to reach 113 calories regardless of how large or small that portion looks compared to a normal cheese slice. This may mean eating 2 to 3 slices of a low-calorie vegan cheese to match one ounce of real cheddar — which is perfectly acceptable as long as the calorie target is met.
Alternatively, nutritional yeast (sprinkled on the crackers in place of cheese) provides a legitimate cheesy, savory flavor at approximately 20 calories per tablespoon. A tablespoon of nutritional yeast on each of five crackers creates a cheese-flavored snack at 100 calories total — reasonable approximation of the cheddar's calorie role, though with a very different texture and eating experience.
Frequently Asked Questions
The best cheddar substitutes are Swiss (1 oz = 106 cal), Colby Jack (1 oz = 110 cal), Gouda (1 oz = 101 cal), or Monterey Jack (1 oz = 106 cal). All are excellent calorie matches at the same 1-ounce portion with similar fat and protein profiles. For dairy-free, use a vegan cheddar or cashew cheese portioned to reach 113 calories — check the specific brand label for accurate portions.
Yes, but adjust the portion upward. Low-fat cheddar typically runs 49 to 70 calories per ounce versus full-fat's 113. To match the full-fat cheddar's calorie contribution, use 1.6 to 2.3 ounces of low-fat cheddar at Day 3 breakfast. Alternatively, eat the 1-ounce low-fat portion and note that Day 3 breakfast will be 43 to 64 calories lighter than specified — a modest and acceptable shortfall.
Any sharpness is fine — mild, medium, sharp, and extra-sharp cheddar all have essentially the same calorie and macro profile at equivalent weights. The aging process that creates sharpness does not significantly change the nutritional content. Sharp cheddar provides more flavor intensity per ounce, which makes the 1-ounce portion feel more impactful on the palate — a minor but real advantage for a small serving.
The best approach for dairy-free dieters is to buy a cashew-based or coconut oil-based vegan cheddar, read the nutrition label carefully, and portion to reach 113 calories regardless of how many physical slices that requires. As a flavor alternative, one tablespoon of nutritional yeast sprinkled on the crackers provides a cheesy, savory flavor at 20 calories — add apple alongside for roughly 115 calories total, a close functional substitute.
