Clean Eatz vs Oats Overnight: Which High-Protein Oats Win?

Both brands list 20g of protein in every flavor, which makes either one more filling than plain oatmeal. Our five flavors run from 270 to 330 calories. Apple Cinnamon is the leanest at 270 calories, 6g fat, 40g carbs. Peanut Butter Cup is 300 calories, 9g fat, 39g carbs. Strawberries & Cream is the richest at 330 calories, 12g fat and 35g carbs, most of the extra from almonds.

Oats Overnight's flavors run from 250 calories (Cinnamon Roll, Pumpkin Pie, Fruity Cereal) to 320 (Butter Pecan Ice Cream). Its French Toast pouch, for example, lists 290 calories, 6g fat, 42g carbs, 7g fiber, 9g sugars with 6g added, and 340mg sodium. Fiber and protein sources vary by flavor, so read the panel for the one you plan to buy.

If you're choosing strictly by calories and fat, the two lineups overlap almost completely. Thirty calories is a few almonds. The protein is the same.

Why the protein matters: a 2021 meta-analysis pooled randomized trials in children and teens aged 7 to 19 and found that a protein-rich breakfast cut energy intake at the next meal by about 111 calories and raised fullness. The authors called most of the studies low quality, and the trials were short. Treat it as a reasonable signal, not a promise for adults. For portion control and the best toppings, see our guide on whether oatmeal is good for weight loss.

This is one of the clearest differences between the two. We keep it simple: oats, whey protein and flavor-specific additions such as fruit, almonds, peanut butter, cinnamon or chocolate. Strawberries & Cream gets strawberries and almonds, and Peanut Butter Cup gets peanut butter and chocolate. If you like a short label you can scan in five seconds, that's the appeal.

Oats Overnight builds a longer recipe. French Toast, for one, lists certified gluten-free whole grain rolled oats, a whey and pea protein blend, maple sugar, chia seeds, date powder, flaxseed, natural flavors, pink salt, spices and monk fruit. Its oats are certified gluten-free by the GFCO, and many flavors use plant protein only.

If you need a gluten-free label, that settles it. Under the FDA's gluten-free labeling rule, a food labeled gluten-free must contain less than 20 parts per million of gluten. We make no gluten-free claim for our oats, so if you have celiac disease or a severe gluten reaction, choose a certified product.

This is where preference decides it. Our oats come in a resealable pouch: add milk straight to the pouch, seal it, refrigerate it overnight and eat from the same pouch in the morning. No bowl, no bottle, and the pouch goes in the trash when you're done.

Oats Overnight is built around its shaker bottle. Pour 8 oz of milk or a milk alternative into the bottle, add the pouch, shake and refrigerate before bed, then drink or spoon it the next day. It also gives directions for a warm bowl: 5 oz of milk, about a minute in the microwave. That suits anyone who wants a drinkable breakfast in the car or a hot one in winter.

Both are meant to be made with milk, not water. Our product page covers cold prep only, so follow the package directions for the exact product you buy. Building a whole make-ahead morning? Our Complete Meal Prep Guide has more ideas.

Price is the detail most likely to change, so here it is as listed in October 2026. Ours is $3.49 a pouch, every flavor. Oats Overnight sells single-flavor packs (4 for $15, about $3.75 a meal, or 8 for $36, $4.50) and mix-and-match boxes of 8 to 40 meals: $39 for 8 one-time, about $4.88 a meal, down to $133 for 40, about $3.33. Subscribe and the boxes run $38 to $126, down to about $3.15 a meal, and the site advertises 25% off a first order.

Compare like with like. A single pouch from one brand against a discounted 40-meal subscription from the other isn't a fair test. Price the format you'd actually buy. If you want a handful of breakfasts, not a box, ours is the simpler buy. Ordered on their own, our oats are a marketplace order, and marketplace-only orders of $40 to $80 carry a $9.99 small-box charge, so they're best added to a meal plan order, which ships free.

For context, homemade overnight oats with protein powder cost less per serving than either brand. The trade is time: a packaged pouch saves you measuring oats, protein and toppings every night.

No contest. About 35 flavors against our five, from Butter Pecan Ice Cream to Matcha Mango, plus a monthly flavor in development. If you get bored of breakfast fast, Oats Overnight gives you more room to rotate.

Our five cover the classics: fruit, peanut butter and cinnamon. That smaller list is a feature for some people and a limit for others.
