This is the keto standard in SF. I ordered Factor to a SoMa office, a Sunset apartment, and a Richmond house over six weeks. Every box showed up cold, every meal stayed under 15g net carbs, and the clinical study data (9.3 lbs lost in 16 weeks) actually holds up if you stick with it. The Cauliflower Mac & Cheese has 4g net carbs and doesn't taste like punishment. The Chicken Tikka Masala has 11g net carbs and 43g protein. Two minutes in the microwave, proper keto macros, no thinking required. Factor reaches every SF ZIP code I tested, which matters when CookUnity ghosts you past Parkmerced.

If Factor is reliable, CookUnity is exciting. Award-winning chefs making keto meals that look like they came from Flour + Water, not a meal prep container. The Moroccan Lamb with cauliflower couscous has 9g net carbs and tastes like an actual restaurant dish. The Korean Short Rib Bowl sits at 8g net carbs with gochujang that doesn't spike your blood sugar. I kept CookUnity running for four weeks in the Mission and never repeated a meal. The problem is coverage. Strong in FiDi, SoMa, and the core neighborhoods, but when I tried to send it to a friend in Daly City, it ghosted. Check your ZIP before you get excited.

Sunbasket isn't keto-specific but the organic low-carb options work if you're flexible. I tested their gluten-free, low-carb meal kits in Noe Valley for two weeks. The Pesto Chicken with zucchini noodles came in around 18g net carbs (not strict keto but close), and the grass-fed beef options were legitimately good quality. You do have to cook these, which takes 25-35 minutes. Not ideal if you're working late at a SoMa startup, but better than Factor if you care deeply about organic sourcing and don't mind the extra carbs. Backed by 98% organic ingredients, which matters to the Rainbow Grocery crowd.

Home Chef has a few meals tagged keto-friendly but this isn't a keto service. I ordered their keto options to the Richmond twice. The Herb Butter Salmon with green beans worked (under 10g net carbs), but the weekly menu only had 2-3 keto-tagged options and you have to cook everything for 30-40 minutes. Better for families in Bernal Heights doing casual low-carb, not for strict keto adherence. The price is right at $8-12/serving, and Kroger backing means delivery reaches the whole city including the Excelsior and Bayview, but don't expect dedicated keto meal planning.

Dinnerly is the budget king at $4.69/meal, but it's terrible for keto. No dedicated keto meals, no low-carb filter, and most recipes have pasta, rice, or potatoes as the main carb. I tried it in the Tenderloin for a week thinking I could modify recipes. The Beef Tacos kit had 45g carbs from tortillas. The Chicken Stir-Fry came with white rice (35g carbs). You'd have to throw away half the ingredients and cook your own sides, which defeats the point of meal delivery. If you're broke and doing lazy low-carb (under 100g/day), maybe. If you're strict keto, skip this entirely.

Blue Apron has been around forever but they're not built for keto. I tested them in Pac Heights for two weeks and found maybe one meal per week that could work for keto if you removed the carb sides. The Seared Steaks with roasted vegetables is fine if you skip the potatoes, but you're paying $10/serving for a meal you have to modify yourself and cook for 35 minutes. At that point just buy a ribeye from Whole Foods and cook it yourself. Blue Apron works for people who like cooking traditional meals. For keto in San Francisco, there are four better options above this one.

100% keto meals, all dishes under 15g net carbs with proper fat ratios (57-83g fat per meal), founded by UC Berkeley grad Chen-Chen Huo

Chen-Chen Huo grew up in his dad's restaurant in Chinatown and built Kitchen Keto specifically for SF's keto crowd. The Cauliflower Carbonara (57g fat, 15g net carbs, $13) actually tastes like carbonara, not like you're being punished. The Butter Lettuce Salad with bacon, hard-boiled egg, bleu cheese has 83g fat and 2g net carbs. I ordered from them twice to the Mission and once to the Marina. Every meal showed proper keto macros on the label, portions were generous, and the packaging survived SF delivery without turning into soup.

$12.25-$13.50 per meal | Serves: Bay Area Wide - SF, Peninsula, South Bay, East Bay, Marin

Gourmet keto and low-carb meal plans with organic ingredients, offers Vegetarian Keto, Halal Keto, and Indian Keto options

Mary started this in late 2020 and it's become the go-to for Bay Area keto people who want organic and are willing to pay for it. The meal plans are fixed four-week menus, so you know exactly what's coming. I didn't test this one personally because the $35-50 delivery fee from Dublin to SF proper makes the math brutal ($20/meal + $50 delivery = not competitive with Factor), but multiple people in the East Bay told me the quality is excellent if you're in the Tri-Valley service area.

$20-22 per meal (5-meal plan $110, 10-meal plan $195, 14-meal plan $250) | Serves: Bay Area within 50 miles of Dublin, CA (SF proper incurs $35-50 delivery fee from Tri-Valley base)

Paleo and keto base with no sugar, dairy, or soy - customizable proteins (pork, salmon, mahi, steak, shrimp) and 20+ sides including cauliflower rice

Livermore-based but they deliver to SF. The customization is the selling point - you pick your protein, pick your sides, and they build it. I ordered the salmon with cauliflower rice and roasted vegetables. Portions are huge (multiple people reported splitting meals for lunch and dinner). The packaging is biodegradable, which matters if you're ordering weekly and drowning in plastic. At $14-15/meal it's more expensive than Factor but cheaper than the SF-based local options, and the Paleo base means it's naturally keto-friendly without trying.

$14-15 per meal | Serves: Bay Area delivery from Livermore kitchen

Keto meal prep with 60-80% fat, 15-35% protein, 0-5% carbs - also offers plant-based keto options

LoCal Foodz has been around long enough that multiple long-term keto people in SF mentioned them. They offer pickup at partnering stores throughout the Bay Area, which saves on delivery fees. I didn't test them personally but the website customization is solid and the macro targets (60-80% fat) are properly ketogenic. Worth checking if you're near one of their pickup locations and want to avoid delivery fees.

Not specified | Serves: All of California and Nevada with SF pickup locations
