Our favorite keto products
The testing kits, protein, electrolytes, and kitchen gear we'd actually buy — with the tradeoffs, not just the hype. We only list things worth recommending, and we tell you where each one falls short.
Ketone testing
Three ways to check whether you are actually in ketosis — blood, urine, and breath. They trade accuracy for cost and convenience.
Best ketone meter: blood vs. breath vs. urine →
Keto-Mojo blood ketone + glucose meter
The blood meter serious trackers use — a finger-prick reading of blood ketones and glucose, the most accurate of the three methods. The meter is a one-time buy; the strips are the ongoing cost.
View at AmazonPerfect Keto urine ketone strips
The cheapest way to start: dip a strip and read the color. Less precise than blood and it fades as you fat-adapt, but fine for confirming ketosis in the first few weeks.
View at AmazonBreath meters read acetone and reuse forever with no strips — but the best one, Biosense, was discontinued in 2024, so there is no standout pick to recommend right now. See our ketone-testing research for how the three methods compare.
Protein bars & shakes
For when a real meal is not happening. The trick on keto is finding ones that are genuinely low in net carbs and easy on the stomach.

IQBAR plant-protein bars
A plant-protein bar with low net carbs and no sugar alcohols — handy in a bag when there is no time to cook.
View at AmazonOWYN Pro Elite protein shake
One of the few ready-to-drink shakes that is genuinely 0g net carbs — dairy-free, 32g plant protein, no sugar. Good travel and post-workout fuel.
View at AmazonIsopure Zero Carb protein powder
A whey isolate at 0g carbs that mixes into a clear drink rather than a creamy shake. Pick this if you want dairy protein without the sugar.
View at AmazonElectrolytes
The most-missed thing in the first keto weeks. Low insulin makes you shed sodium and water fast, and the 'keto flu' is mostly that.
Best keto electrolytes: what to actually buy →
Redmond Re-Lyte hydration mix
Zero-sugar electrolytes with a real-salt sodium, potassium, and magnesium balance — the mix most people are short on early on. No sweetener aftertaste in the unflavored one.
View at AmazonFats & coffee
A fast, clean fat source for coffee, dressings, and quick energy.
Best MCT oil for keto: C8 vs. C10 vs. blends →Best keto coffee: bulletproof, creamers, and add-ins →
Bulletproof C8 MCT oil
C8 MCT oil for coffee or dressings — a fat the body turns to fuel quickly. Start with a teaspoon; too much too soon is famously rough on the gut.
View at AmazonSweeteners
The two that behave most like sugar in keto baking. See our cups-to-grams guide for weighing them.
Best keto sweetener: allulose vs. monk fruit vs. erythritol →
RxSugar allulose
Allulose measures and browns like sugar without the cooling aftertaste erythritol leaves — the closest thing to real sugar for keto baking.
View at AmazonLakanto monk-fruit sweetener
A monk-fruit and erythritol blend that swaps 1:1 for sugar and is easy to find. Some people taste the cooling note; some do not.
View at AmazonPantry staples
The everyday swaps that make keto feel less like a restriction.
Best keto flour: almond vs. coconut →
Mission Carb Balance tortillas
High-fiber flour tortillas at about 2g net carbs — the easiest keto swap for tacos, wraps, and quesadillas. In most grocery stores; the link is for convenience.
View at AmazonBlanched almond flour
The workhorse keto flour — fine grind, mild flavor, low net carbs. Weigh it rather than scooping; a packed cup throws off both the carbs and the texture.
View at AmazonCoconut flour
Cheaper and far more absorbent — it drinks up liquid, so recipes use a fraction of what they would with almond flour. The go-to if you are avoiding nuts.
View at AmazonSnacks & chips
The crunchy, grab-and-go stuff that keeps keto from feeling like a diet — mostly protein and fat, at near-zero carbs.
Best keto snacks →Best keto chips →
Cheese crisps
Crisps made of 100% baked cheese — crunchy, zero-carb, and the closest thing to a chip on keto. Easy to overeat, so mind the handful.
View at AmazonPork rinds
Zero-carb and crunchy, and they double as a chip or a breadcrumb swap. The plain ones are just pork and salt.
View at AmazonKitchen gear
A couple of cheap tools that pull their weight on keto.
Digital kitchen scale
The single most useful keto tool. Weighing in grams beats measuring in cups — especially for almond and coconut flour — and makes our recipe tables exact. See the cups-to-grams guide.
View at AmazonVegetable spiralizer
Turns zucchini into noodles for dishes like our shrimp scampi — a cheap way to make low-carb pasta swaps feel like the real thing.
View at AmazonThe one keto tool that isn't on this list
Copper Keto Companion is the voice-first coach that works out the net carbs on whatever you eat — no weighing, no database. Say what you had and it does the math.
