Atkins Phase 1 food list PDF with net carbs

Key takeaways

Phase 1 Induction caps net carbs at 20g a day, which is what moves the body into ketosis.

Foundation vegetables carry 12 to 15g of that allowance. Protein and fat carry none, so patients eat them freely.

Nuts and seeds wait until week 3. Sugar, grains, fruit, starchy vegetables and alcohol stay out for the whole phase.

The free PDF holds the food tables, the avoid list, a 7-day meal plan and a daily net carb tracker.

Practice management software like Pabau carries the intake forms, the monitoring schedule and the visit notes behind the intervention.

The Atkins Phase 1 food list PDF below gives you every food Induction allows, with the net carbs each serving costs. Phase 1 holds you to 20g of net carbs a day. Protein and fat carry none, so they stay unlimited. Foundation vegetables take 12 to 15g of that, and the rest of the plate should cost you none.

Below you get the printable list, the carb values, the foods to avoid, a 7-day plan, and the mistakes that catch people out.

Phase 1 means 20g of net carbs a day

Atkins Phase 1, called Induction, is the opening stage of the Atkins 20 program. It runs for a minimum of two weeks and holds net carbohydrates to 20g a day. That restriction moves the body into ketosis, a metabolic state where fat becomes the main fuel instead of glucose.

Induction works as a reset for insulin sensitivity and appetite. Sugars, grains, fruit and starchy vegetables come off the plate entirely. Teams at weight-loss practices report steadier blood sugar, fewer cravings and measurable fat loss in the first 7 to 10 days.

• Net carb limit: 20g a day, for the whole phase
• Duration: two weeks minimum, often extended to four
• Carb source allowed: foundation vegetables only
• Protein: beef, pork, lamb, poultry, fish, shellfish, eggs
• Fat: oils, butter, ghee, cream, avocado
• Move to Phase 2 when: the weight-loss target is met or appetite settles, usually at week 2 to 4

What the five printable pages cover

The download is a five-page document, built to be handed to a patient at the first appointment.

• Page 1: patient and start-date fields, how to use the list, the protein table and the dairy table
• Page 2: the foundation vegetable table, fats and oils, and the nuts and seeds table
• Page 3: drinks, the net carb formula worked through, and the foods to avoid
• Page 4: the 7-day sample meal plan and a blank daily net carb tracker
• Page 5: guidance for the supervising practice, the week 0 to week 8 monitoring schedule, and a notes box

Who the list is written for

• Patients starting Induction: one printed page replaces the memory work of a verbal briefing.
• Weight-management practices: every patient starts on the same numbers and the same serving sizes.
• Dietitians and nutrition coaches: the tracker turns adherence into something you can review rather than guess at.
• Primary care teams: the monitoring schedule sets out what to record and when to review the intervention.

Net carbs are the only number you track

Net carbs are what Phase 1 counts, and the arithmetic is the same on every label. Subtract fiber and half of any sugar alcohol from the total carbohydrate. Fiber and most sugar alcohols pass through without raising blood glucose, which is why they come out of the count.

The formula: total carbohydrate − dietary fiber − (sugar alcohols ÷ 2) = net carbs

Meat, fish, eggs and cooking fats sit at zero. Build the meal around them and the only items left to count are vegetables, dairy and, later, nuts.

Every food Induction allows, and what it costs

Every food below is permitted during Induction, grouped the same way the printable version groups them. Values are per standard serving and rounded to one decimal place.

Protein: Meat, fish and eggs sit at zero

All of these sit at 0g net carbs, so there is no daily cap on them. Oysters and mussels are the exception at roughly 4g per 3 oz, so those need counting.

• Beef, all cuts: 0g net carbs per 3 oz
• Pork, including bacon and unsweetened ham: 0g net carbs per 3 oz
• Lamb: 0g net carbs per 3 oz
• Chicken and turkey, skin included: 0g net carbs per 3 oz
• Fish, such as salmon, tuna, cod and sardines: 0g net carbs per 3 oz
• Shellfish, such as shrimp, crab and lobster: 0g net carbs per 3 oz
• Eggs, any preparation: 0g net carbs per large egg

Foundation vegetables: 12 to 15g a day

Foundation vegetables are the only carbohydrate Phase 1 permits. Spend the 12 to 15g allowance across the day rather than in one meal. The carb cost varies far more between them than the serving sizes suggest.

Dairy: Cheese, cream and butter, but not milk

• Butter: 0g net carbs per tablespoon
• Hard cheese, such as cheddar, mozzarella and brie: 0 to 1g net carbs per ounce
• Heavy cream, unsweetened: 0.4g net carbs per tablespoon
• Cream cheese: 1g net carbs per ounce
• Sour cream: 1g net carbs per tablespoon

Milk and yogurt stay off the list during Induction. Both carry more sugar than a 20g allowance can absorb.

Fats and oils: Use them to reach satiety

Every cooking fat is approved and every one sits at zero net carbs. Cook with them freely and eat until you are full, since fat is what makes a 20g day comfortable.

• Olive oil
• Coconut oil
• Avocado oil
• Butter
• Ghee
• Lard

Nuts and seeds wait until week 3

Nuts and seeds stay out for the first two weeks. If Induction runs longer than that, they can come in, counted against the same 20g ceiling.

• Pumpkin seeds: 1g net carbs per ounce
• Macadamia nuts: 1.5g net carbs per ounce
• Sunflower seeds: 1.5g net carbs per ounce
• Walnuts: 1.9g net carbs per ounce
• Almonds: 2.5g net carbs per ounce, about 23 nuts

Drinks: water, coffee, tea and broth

• Water, still or sparkling
• Black coffee
• Unsweetened tea
• Clear broth, which also helps with the sodium loss of week 1
• Cream in coffee, counted against the daily total

What to leave off the plate for two weeks

The restricted list matters as much as the approved one. Each group below either blows the 20g allowance on its own or raises blood glucose enough to interrupt ketosis.

• Sugars and sweets: table sugar, honey, maple syrup, agave, candy, desserts, full-sugar soft drinks, fruit juice
• Grains and starches: bread, pasta, rice, cereal, oats, flour, corn, potatoes
• Fruit: all fruit during the first two weeks, with a small portion of berries possible after week 2
• Starchy vegetables and legumes: peas, carrots, sweet potato, beets, beans, lentils, chickpeas
• Alcohol: beer, wine, spirits and mixers
• Low-fat and diet products: low-fat dressings, low-fat cheese, fat-free yogurt, most of which carry added sugar
• Sweeteners: keep artificial sweeteners to a minimum, since some patients report that cravings return with them

Phase 1 is an elimination phase, so the carb sources come out together rather than one at a time. Phase 2 brings some of them back in measured portions, which is where a structured clean eating meal plan takes over.

Before day one: A five-point checklist

Much of what decides the first two weeks happens before a single meal is eaten. Work through this list at the appointment where the food list is handed over.

• Get medication reviewed. Insulin, sulfonylureas, diuretics and blood-pressure drugs often need adjusting once carbohydrate drops.
• Clear the kitchen. Bread, cereal, juice, snack food and sweetened sauces go out before day one, not on day three.
• Put measuring cups or a scale where you cook. Portion drift is the most common reason a first attempt stalls.
• Fix the start date and the Phase 2 date together. A visible end date makes two weeks of restriction much easier to hold.
• Stock salt and clear broth. Sodium loss in week 1 causes most of the fatigue people report on days three to five.

Then build the first shop straight from the approved tables above. A ready-made weight-loss grocery list saves the patient a second trip for what they forgot.

How to work the list, day to day

Five steps take a patient from the printed page to a logged first week.

1. Print the list or share it digitally on the day Induction starts.
2. Fill in the patient name, the start date and the Phase 2 review date at the top.
3. Mark the foods the patient already eats, so the first grocery list writes itself.
4. Weigh or measure vegetable servings for the whole of week 1.
5. Log each day on the tracker and bring it to the week-2 appointment.

Here is what a day near the limit looks like. Breakfast of three eggs and bacon costs 0g. A lunch salad of raw spinach with half an avocado costs about 2g. Dinner with a cup of cooked broccoli and a cup of raw cauliflower adds roughly 9g. Two tablespoons of cream in the coffee take the day near 12g, which leaves headroom for a bigger salad.

A sample week that lands near 20g

Use this week as a starting framework. Each day lands near 18 to 20g of net carbs when vegetable servings match the sizes in the table above.

Salt food to taste and drink to thirst. Sodium loss is normal in week 1, and it drives most of the fatigue patients report on days three to five.

Five things that quietly stall Phase 1

Almost every stalled Induction traces back to one of the same five habits. None of them look like cheating, which is why they survive a whole fortnight unnoticed.

• Fat gets cut as well as carbs. Dropping both leaves the patient hungry by mid-afternoon, and hunger is the fastest route to a broken Induction. Cook in butter or oil and eat to satiety.
• Servings get eyeballed. One cup of cooked broccoli already costs 6.6g, so a generous second helping can spend the whole vegetable allowance. Measure for the first week, then estimate.
• Sauces slip through. Marinades, dressings, glazes and cured meats often carry added sugar. Read the label on every bottle, jar and packet before it reaches the pan.
• Salt gets cut out of habit. Sodium drops quickly in week 1, and that is what produces the headache and fatigue on days three to five. Salt food to taste and keep broth in the cupboard.
• Nuts arrive early. Almonds cost 2.5g an ounce and a handful is easy to repeat. They belong in week 3, once the two-week minimum is behind you.

Supervising Induction in a practice

Phase 1 is a short, aggressive intervention, so the supervision around it has to be structured. Four things carry most of the outcome.

Hand the list over at the first appointment

Patients forget spoken instructions within minutes, so the printed list does the work the consultation cannot. Capture dietary history, medication and weight goals on patient intake forms beforehand, then mark up the list against what that patient already eats.

Record a baseline, then repeat it on schedule

Take weight, blood pressure, a lipid panel and fasting glucose before day one. Then repeat them on a fixed schedule, so week 0 and week 8 can be read side by side rather than hunted for.

Warn about days three to five before they arrive

Headache, fatigue and irritability are common as glycogen and sodium drop. Say so at the first appointment, because a patient who expects it rarely quits over it. Sodium, potassium and magnesium usually settle the symptoms, and they pass on their own.

Eating out is the other early sticking point. Rehearse two or three orders with the patient, such as a bunless burger, extra vegetables and an oil-based dressing.

Record the barrier and the fix in the chart so the whole team gives the same answer next visit. Pabau Scribe, our AI scribe, writes that note from the consultation itself.

Know what Phase 2 actually changes

Induction runs two to four weeks. Phase 2, called Balancing, raises the ceiling to 25g of net carbs a day. It also brings nuts, more dairy and small portions of berries back onto the plate, which is the reward most patients are counting down to.

How Pabau keeps a Phase 1 program on schedule

Most practices run a Phase 1 program on paper and memory. The food list is a printout. Adherence lives in a notebook the patient forgets to bring, and the week-2 recall depends on somebody remembering to make the call. Baselines get taken, then sit in a scan nobody opens again.

Practice management software like Pabau puts the same program on one record. Digital intake forms collect dietary history, medication and weight goals before the patient arrives. Measurements hold weight, blood pressure and lab values against the schedule above, so week 0 and week 8 sit in one view.

Automations handle the follow-up. A week-2 recall books itself, and the Phase 2 education email sends on the date you set. Pabau Scribe turns each consultation into a note without the charting time. Your team sees the whole intervention on one timeline, so the plan agreed at visit one never has to be reconstructed.

Run dietary interventions on one record

Digital intake forms, measurement tracking and automated week-2 recalls keep an Atkins Phase 1 program on schedule. See how Pabau brings the whole intervention onto one patient timeline.

Conclusion

Phase 1 comes down to three numbers. Net carbs stay at 20g a day, 12 to 15g of them come from foundation vegetables, and the phase runs two weeks minimum. The list turns those numbers into a shopping trip and a week of meals, which is the part a patient can act on.

So download the PDF, hand it over on day one, and keep the tracker coming back with the patient. The two weeks are short enough that a missed follow-up costs you the whole intervention.
