What Is the OPTAVIA 3 and 3 Plan?
The OPTAVIA 3 and 3 Plan is the maintenance phase of the OPTAVIA program. It replaces two of the five daily Fuelings with home-cooked Lean and Green meals, giving members more food flexibility. The plan targets long-term weight maintenance after completing the initial 5 and 1 weight loss phase.
Most people reach the 3 and 3 after hitting goal weight on the 5 and 1. Between the two sits the OPTAVIA transition plan, a 3-week bridge ending at 1,200 calories. OPTAVIA recommends the switch after approximately 12 weeks of the initial program. The full name is the Optimal Health 3 and 3 Plan, and it is considered the sustainable lifestyle phase of the OPTAVIA approach.
The plan structures six eating occasions each day. Three are OPTAVIA Fuelings and three are home-cooked Lean and Green meals. Each occasion is spaced 2 to 3 hours apart to keep blood sugar stable and reduce hunger throughout the day.
How Is the 3 and 3 Plan Different from the 5 and 1 Plan?
The 5 and 1 Plan is the active calorie-restriction phase of OPTAVIA. It limits intake to 800 to 1,000 calories daily through five Fuelings and one home-cooked Lean and Green meal. The 3 and 3 Plan replaces two of those Fuelings with full Lean and Green meals, raising calorie intake and reducing reliance on packaged products.
The 5 and 1 Plan drives rapid weight loss over weeks. The 3 and 3 Plan shifts the focus entirely to maintenance and building sustainable eating habits. Calorie intake on the 3 and 3 Plan typically ranges from 1,100 to 2,500 per day, depending on individual size, activity level, and maintenance needs.
Key differences at a glance:
| Feature | 5 and 1 Plan | 3 and 3 Plan |
|---|---|---|
| Goal | Active weight loss | Weight maintenance |
| Daily Fuelings | 5 | 3 |
| Lean and Green meals | 1 | 3 |
| Calorie range | 800-1,000 | 1,100-2,500 |
| Food variety | Limited | Higher |
Food preparation increases significantly on the 3 and 3 Plan. Members go from cooking one meal daily to preparing three full Lean and Green meals. That shift builds real cooking skills and a lasting connection to whole-food eating.
How Does the OPTAVIA 3 and 3 Plan Work?
The OPTAVIA 3 and 3 Plan works by alternating structured Fuelings with home-cooked meals throughout the day. Each day includes three OPTAVIA Fuelings and three Lean and Green meals, spread across six eating occasions. The 2 to 3 hour gap between each occasion keeps hunger manageable without long fasting stretches.
An Independent OPTAVIA Coach guides each member through the transition. Coaches help set maintenance calorie targets and navigate the shift from relying on packaged Fuelings to building balanced home-cooked plates. Regular check-ins provide accountability and early correction when habits drift.
The 3 and 3 Plan also incorporates OPTAVIA's Habits of Health system. These are structured lifestyle practices covering sleep, hydration, movement, and stress management. The plan is designed as a whole-life maintenance approach, not just a meal schedule.
What Are the Lean and Green Meals on the 3 and 3 Plan?
A Lean and Green meal is a home-cooked plate built around lean protein and non-starchy vegetables. Each meal contains 5 to 7 ounces (140 to 200 grams) of lean protein, three servings of non-starchy vegetables, and up to two servings of healthy fat. The combination delivers complete protein and fiber without excess carbohydrates or calories.
Lean protein sources include skinless chicken breast, white fish, turkey breast, eggs, shrimp, and tofu. Non-starchy vegetables include broccoli, spinach, cauliflower, zucchini, asparagus, and bell peppers. Healthy fats come from measured portions of olive oil, avocado, or unsalted nuts.
Approved Lean and Green foods:
- Lean proteins: chicken, turkey, white fish, shrimp, eggs, tofu, lean ground beef
- Non-starchy vegetables: spinach, broccoli, cauliflower, peppers, zucchini, asparagus
- Healthy fats: olive oil (1 tsp), avocado (1/4 fruit), almonds (1 oz / 28 g)
Cooking methods matter on the plan. Grilling, baking, steaming, and sauteing are all allowed. Breaded preparations, fried coatings, and high-calorie sauces are excluded from Lean and Green meals.
What Are the Fuelings on the 3 and 3 Plan?
OPTAVIA Fuelings are portion-controlled meal replacement products designed for structured eating. Each Fueling provides 100 to 110 calories, approximately 15 grams of protein, and essential vitamins and minerals. The macronutrient ratio is formulated to support lean muscle retention during both weight loss and maintenance phases.
More than 60 Fueling varieties are available. Options include chocolate protein shakes, cheese puffs, pancakes, brownies, soups, and mac and cheese. The product range is intentionally wide to reduce flavor fatigue and support daily adherence over months.
On the 3 and 3 Plan, Fuelings serve as structured snacks between the larger Lean and Green plates. Three Fuelings daily still provide around 330 calories of reliable, protein-rich nutrition. The difference from the 5 and 1 Plan is that whole-food meals now form the majority of total daily intake.
What Are the Benefits of the OPTAVIA 3 and 3 Plan?
The OPTAVIA 3 and 3 Plan offers more variety and flexibility than any prior OPTAVIA phase. Three daily home-cooked Lean and Green meals allow for a wider range of foods, flavors, and cooking styles. The shift away from five packaged Fuelings per day supports better long-term dietary habits and reduced dependence on processed products.
Ongoing coaching is a core advantage of the plan. An Independent OPTAVIA Coach helps members calibrate portion sizes, troubleshoot cravings, and stay accountable through the first critical weeks of maintenance. Research consistently shows that social support and structured accountability improve long-term adherence in lifestyle programs.
Physical benefits from the 5 and 1 phase often carry forward into the 3 and 3. Reduced blood pressure, improved energy, and lower inflammation markers are commonly reported. Higher daily protein intake from three Lean and Green meals also continues to support lean muscle mass during the maintenance period.
Does the 3 and 3 Plan Support Long-Term Weight Maintenance?
Long-term weight maintenance is the explicit design goal of the 3 and 3 Plan. The plan transitions members from the restrictive 5 and 1 phase into a sustainable whole-food eating pattern. Structured eating occasions, accurate portion guidance, and coaching accountability are the three tools the plan uses to make that transition stick.
A 2026 study by Christopher D Coleman from the Department of Scientific and Clinical Affairs, published in Clinical Obesity, examined 124 adults randomized to OPTAVIA or Medifast. Researchers found that early weight loss within the first 2 to 4 weeks of the program was the strongest predictor of achieving clinically significant weight loss of 5 percent or more. Members who reached early weight loss thresholds were significantly more likely to sustain their results through the full program.
Consistency in eating timing reinforces maintenance outcomes. Skipping Fuelings or delaying Lean and Green meals disrupts the calorie balance the plan depends on. Our coaches at Optimal Weight Plan treat each of the six daily eating occasions as a non-negotiable commitment, not an optional habit.
What Do You Eat on the OPTAVIA 3 and 3 Plan?
Daily eating on the 3 and 3 Plan centers on three Fuelings and three full home-cooked Lean and Green meals. Lean proteins, non-starchy vegetables, and healthy fats anchor the home-cooked portion of the day. Fuelings fill structured gaps between meals and provide reliable protein and micronutrient support without preparation time.
A sample day looks like this: a vanilla shake Fueling at 8 AM, grilled salmon and broccoli at 11 AM, a crunchy snack Fueling at 2 PM, chicken and zucchini stir-fry at 5 PM, a chocolate brownie Fueling at 7:30 PM, and a turkey lettuce wrap plate at 9 PM. That spacing keeps all six eating occasions moving through the day without any gap longer than three hours.
The plan does not require precise calorie counting on each meal. Portion control comes from following Lean and Green meal specifications. Measuring protein portions and vegetable servings accurately matters far more than tracking individual macros.
What Foods Are Not Allowed on the 3 and 3 Plan?
Excluded foods on the 3 and 3 Plan include refined grains, added sugars, fried foods, and most processed snacks. White bread, pasta, white rice, and crackers are not part of the plan. High-sugar fruits like bananas, grapes, and mangoes are limited or excluded during active maintenance because of their effect on blood sugar stability.
Starchy vegetables do not count as Lean and Green vegetables. Corn, peas, potatoes, and sweet potatoes carry too many carbohydrates for the plan's macronutrient targets. Beans and lentils are excluded unless used as a specific lean protein substitution in a plan variant.
Foods to avoid on the 3 and 3 Plan:
- Refined grains: white bread, pasta, white rice, crackers
- Starchy vegetables: corn, peas, potatoes, sweet potatoes
- High-sugar fruits: bananas, grapes, mangoes, pineapple
- Fried foods and high-fat sauces or dressings
- Alcohol during the active maintenance phase
Reading labels on any packaged item is essential before including it in a Lean and Green meal. Some foods permitted on standard balanced diets fall outside the 3 and 3 framework because they disrupt the calorie and macronutrient targets the plan is built on.
What Results Can You Expect from the OPTAVIA 3 and 3 Plan?
Results on the 3 and 3 Plan depend primarily on consistency in following the six-meal eating schedule. Most people enter the 3 and 3 Plan after reaching their goal weight on the 5 and 1. The primary expected outcome is maintaining that weight within a 2 to 5 pound (0.9 to 2.3 kg) window of the goal.
Some members continue to lose small amounts of weight during the early 3 and 3 weeks. This happens when total calorie intake stays slightly below the individual maintenance threshold. The result is a slow, steady reduction rather than the faster pace typical of the 5 and 1 Plan.
Energy levels typically improve noticeably on the 3 and 3 Plan. More whole-food meals and higher total daily calories support better physical function and mental clarity. Members frequently report feeling less food-focused and more physically capable compared to the more restrictive 5 and 1 phase.
How Long Does It Take to See Results on the 3 and 3 Plan?
Weight maintenance results become measurable within the first 4 to 6 weeks of the 3 and 3 Plan. During this window, the body adjusts to the higher calorie intake and three whole-food meals daily. A stable weight reading across multiple consecutive weeks confirms that the 3 and 3 calorie level matches the individual maintenance threshold.
The first two weeks often show minor weight fluctuations. Water retention from increased carbohydrate intake in whole-food meals can account for 1 to 3 pounds (0.5 to 1.4 kg) of temporary scale increase. This is not true weight gain and resolves within 10 to 14 days as the body stabilizes.
Long-term results depend on continuing the plan beyond the initial transition period. Members who complete a full 12-week 3 and 3 phase show the strongest maintenance outcomes. Our team at Optimal Weight Plan tracks member progress through regular coach check-ins to catch any drift before it compounds.
What Are the Common Mistakes on the OPTAVIA 3 and 3 Plan?
The most common mistake on the 3 and 3 Plan is skipping Fuelings or replacing them with off-plan snacks. Each skipped Fueling creates a protein and calorie gap that is hard to recover from without overeating at the next meal. The six-meal rhythm is the structural backbone the entire plan is built on.
Overeating at Lean and Green meals is a second frequent error. Home-cooked meals require accurate portion measurement of protein, vegetables, and fats. Eyeballing portions without measuring leads to calorie creep over days and weeks. That creep is the most common trigger for gradual weight regain on any maintenance diet.
A third mistake is stopping coach contact after the first transition weeks. Ongoing coaching provides accountability and early course correction. Members who disengage from their Independent OPTAVIA Coach are more likely to drift from the plan within 30 to 60 days, and less likely to catch the drift before it becomes real weight regain.
Is the OPTAVIA 3 and 3 Plan Right for You?
The 3 and 3 Plan is best suited for people who have completed an initial OPTAVIA weight loss phase and reached their goal weight. Those transitioning from the 5 and 1 Plan with an active coaching relationship already in place are the strongest candidates. Adults seeking a structured maintenance approach with built-in daily accountability benefit the most from the plan.
The plan may not suit people who prefer fully independent eating without structured products. Three Fuelings per day represents a real ongoing monthly cost. The total expense varies by usage and coach, but it is a factor worth calculating before committing to the 3 and 3 as a long-term lifestyle.
People with specific medical conditions, food allergies, or clinical nutrition needs should consult a healthcare provider before starting. The 3 and 3 Plan is a structured wellness approach for generally healthy adults. It is not designed as a medical nutrition therapy program or a substitute for clinical dietary management.
