Thanks for being a part of the Quantified Diet Project, one of the most ambitious projects ever to learn what works in dieting.
Whether you stick to your diet every day or not, please fill out the surveys we send you and track your progress on Lift. Your responses are really important—and much appreciated.
- Your diet in a nutshell: Eat lean meats, beans, and veggies. Don’t eat fruit, white foods (bread, potatoes, pasta), or sugar. Give yourself a cheat day each week, where you’re allowed to eat any of the banned foods.
- Buy the book. This diet is based on Tim Ferriss’ book, The 4-Hour Body.
- Track the diet on Lift. We’ve set up the plan so that you’ll eat one meal on the diet on the first day, two meals on the diet on the second day, and fully adopt the diet on the third day.
- Read this guide. If you have more questions, ask them in the discussion section when you check in to Lift.
- Get a diet buddy. Ask a family member, friend or coworker to join the Quantified Diet and help keep you accountable.
WHY IS THIS DIET HEALTHY?
On the Slow-Carb Diet, you’ll rapidly burn fat by avoiding foods that promote fat storage. Metabolism hacking techniques like eating immediately upon waking up and binging on “cheat” foods once a week will help you lose excess fat.
We ran a trial of this diet with 3500 people: 84% of finishers lost weight and the average weight loss was 8.6 pounds. 14% of people lost more than 14 pounds. Read about the research.
WHAT CAN YOU EAT?
Follow these rules if you want to lose weight on the Slow-Carb Diet:
- Stick to Slow-Carb Diet approved foods 6 days a week: lean meat, beans, and veggies and no white foods like sugar, pasta, rice, bread, cheese.
- Eat the same few meals over and over again, especially for breakfast and lunch. You probably do this already; you’re just picking new default meals.
- Don’t drink calories. 1-2 glasses of red wine is okay.
- Start your day with protein, shooting for 30g within 30 minutes of waking (boosts success rate by 11%).
- Don’t eat fruit. Tomatoes and avocados are allowed in moderation.
- Take one “cheat day” a week: Eat whatever you want on cheat days. Tim recommends Saturday for social purposes.
Slow-Carb Diet approved foods
You can eat as much of the following foods as you want. If the food isn’t on this list (e.g. nuts), eat it in moderation. Tim lost the most fat when eating foods that are starred. Here’s where we got the list (and other tips from Tim).
- *Egg whites with 1–2 whole eggs for ﬂavor (or, if organic, 2–5 whole eggs, including yolks)
- *Chicken breast or thigh
- *Black beans
- *Beef (preferably grass-fed)
- *Lentils (also called “dal” or “daal”)
- Pinto beans
- Red beans
- *Mixed vegetables (including broccoli, cauliﬂower, or any other cruciferous vegetables)
- *Sauerkraut, kimchee (full explanation of these later in “Damage Control”)
- Green beans
The ideal breakfast is 30g of protein within 30 minutes of waking up. Eggs are an easy way to do this (and boost success rate by 10%). Some meal ideas:
- Smoothie with 30g of protein powder
- 3 eggs (16g) with 3 slices of Canadian bacon (13g)
- 2 eggs (12g) with 1/2 cup black beans (20g), salsa and guacamole
- 3 servings of spinach or broccoli frittata (30g or 5-6 eggs plus some protein from the veggies)
Caffeine is okay! Drink unsweetened coffee or tea without milk or cream. If you drink caffeinated soda in the morning, limit it to one can of diet soda a day.
Lunch and Dinner
Most of your meals will be a combination of protein + vegetables from the list above. Here’s a tip: Cook in bulk so that you have leftovers for a couple of days (or freeze individual serving sizes for much later). Here are some ideas:
- Roasted chicken with mixed vegetables
- Salad bowl at Chipotle: hold the corn salsa, sour cream and cheese and add guacamole
- Mustard-crusted pork loin with spinach and mushrooms
- Steak with ghee and asparagus or green beans
- Tunafish with mustard and/or salsa with a fresh spinach salad
- Homemade burrito bowl: leftover chicken breast, black beans, salsa and guacamole
- Lentil stew
- Beef and bean chili
- Meat and vegetable curry
Drink lots of water and drinks with zero calories. Make these substitutions for beverages with calories that you’d normally drink:
- Flavored water with lemon or vegetables
- Unsweetened beverages like tea are okay. Limit diet soda to one per day
- Coffee with cinnamon instead of cream or tea with lemon
- Diet soda (max 1 per day)
- Red wine (max 1-2 glasses per day)
Sticking to the diet when eating out
Your default strategy should be to replace any carbs with vegetables and beans. Here are some ideas:
- Burrito salad bowl or any dish with vegetables swapped out for rice/wheat
- Thai curry or soups without rice
- Salad without cheese, croutons
- Indian food: lentils, dairy-free vegetable or bean dishes
- Grass-fed beef burger without the bun or ketchup
- Roasted, baked or grilled protein with vegetables
Keep a list of Slow-Carb Diet friendly restaurants nearby. Find meals you like and repeat them. Alternate days if it’s too boring. This makes meal planning into a breeze. 28% of people scrambled to find acceptable meals during our previous research, which put them at more risk to eat off-diet (-4% effect on success rates).
What to eat when you’re in a rush
A lot of the foods on the 4HB can be made in a snap. Keep basics like eggs, frozen veggies, canned beans, canned tuna and spinach leaves on hand so you can turn them into quick meals. Here are some meal ideas:
- Eggs with black beans and salsa
- Tuna or leftover protein with frozen veggies
- Quick bean salad
- Protein smoothie
Sticking to the diet while traveling
Sticking to the diet while traveling is all about preparation. Haphazard eating correlates with less weight loss (presumably because of off-diet eating). These 4HB foods are easy to take along on any trips:
- Tuna in pouches or easy-peel cans
- Nuts and nut butters
- Canned beans
- Protein powder you can mix with water
Tips for saving money
Tim calls the extra money you spend on healthier foods “fat tax.” What you spend on healthy food now you’ll save in medical bills or unhappiness later on. There are ways to save money on the diet, here’s how:
- Buy frozen vegetables.
- Buy beans dried and in bulk (but the time you save on the canned stuff is so worth it).
- Cook at home (here are tips).
- Shop at farmers markets and local grocery stores for produce and meat.
- Skip the more expensive foods like grass-fed beef and asparagus.
- Stick to water as your beverage and skip on the wine.
- Buy in bulk.
- Get a group together to follow the diet and take turns cooking dinner (cooking for one is expensive!). You’ll save some money and have fun.
Don’t cut calories
Don’t worry about calories. Always eat until you are full. It turns out that your body digests calories from different macronutrients (fats, proteins, and carbohydrates) differently. Learn the science behind why.
Get enough protein
You should be getting at least 20g of protein at each meal and 30g for breakfast. This will keep you full longer and help you burn fat.
Eat your meals slowly
Your body has natural cues that tell you when to stop eating, which get messed up when you scarf down your meal. Slow down when you’re eating. Stop before each bite. Take 30 minutes to eat your food. You’ll eat less and feel better (since you won’t feel grossly full).
Limit foods you tend to overeat
Some foods like nuts, chickpeas, hummus, and nut butters are allowed on the diet but can halt your weight-loss if you consume too many calories from them. If you’re trying to lose weight, the easiest solution is to limit them or avoid them completely.
Eat lots of veggies
Not eating vegetables on the diet correlates with less weight loss, so eat up! You can eat these as many of these vegetables as you want: spinach, mixed vegetables (including broccoli, cauliﬂower, or any other cruciferous vegetables), sauerkraut, kimchee, asparagus, peas, broccoli, green beans.
Eat whatever you want on your cheat day
Indulge in whatever you want once a week. Ideally, your first meal should still consist of 30g of protein, but eat whatever you want after that. Last year’s research showed us that what you ate on cheat days and how excessively you indulged did not affect how much weight you lost. Sweets were the biggest craving: 61% of people ate them at on cheat days.
