📌 Quick Answer: Use this Optavia TEE calculator to find how many calories your body burns daily (Mifflin-St Jeor formula). Then choose your plan: TEE under 1,500 → 5&1 (800–1,000 kcal), TEE 1,500–2,000 → 4&2&1 (1,100–1,300 kcal), TEE over 2,000 → 3&3 (1,500+ kcal) .

TEE under 1,500 → 5&1 Plan (800–1,000 kcal)
TEE 1,500–2,000 → 4&2&1 Plan (1,100–1,300 kcal)
TEE over 2,000 → 3&3 Plan (1,500+ kcal)
Formula: Mifflin-St Jeor BMR × Activity Factor
Recalculate every 10–15 lbs lost
Most people overestimate activity level
ℹ️ This Optavia TEE calculator uses the Mifflin-St Jeor equation, the most accurate formula for estimating Basal Metabolic Rate (BMR) in adults. It then multiplies by an activity factor to get Total Energy Expenditure (TEE) .
💡 Important: The Optavia plan tiers used here (5&1 under 1,500 TEE, etc.) are community conventions, not official Optavia medical guidance. Always confirm with your Optavia coach or physician.

What Is the Optavia TEE Calculator?
This Optavia TEE calculator 2026 estimates your Total Energy Expenditure — the calories your body burns daily — using the Mifflin-St Jeor equation. That's the most accurate formula for Basal Metabolic Rate (BMR) in adults .
The calculator then multiplies your BMR by an activity factor (1.2 to 1.9) to get your TEE. Based on your TEE, it recommends one of three Optavia plan tiers: 5&1, 4&2&1, or 3&3 .
This answers the most common question: "How many calories should I eat on Optavia?" The answer depends on your TEE, not a fixed number.
How the TEE Formula Works
The Mifflin-St Jeor equation is the gold standard for BMR estimation :
Male BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) + 5
Female BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) − 161
TEE = BMR × Activity Factor
Activity factors range from 1.2 (sedentary) to 1.9 (extra active). The calculator applies these automatically based on your selection .
The Three Optavia Plans Explained
5&1 Plan (800–1,000 kcal): Five Optavia fuelings plus one Lean & Green meal. This is the most aggressive plan, designed for maximum weight loss when TEE is under 1,500. The 500–700 calorie deficit drives 1–2 lb loss per week .
4&2&1 Plan (1,100–1,300 kcal): Four fuelings, two Lean & Green meals, and one optional snack. This balanced plan is best for TEE between 1,500 and 2,000, where the aggressive 5&1 deficit would be too steep .
3&3 Plan (1,500+ kcal): Three fuelings and three regular meals. Designed for maintenance or highly active individuals with TEE above 2,000. The deficit is smaller (200–500 kcal) for gradual loss or weight maintenance .
Why Activity Level Matters Most
Most people overestimate their activity level, which leads to overeating and stalled weight loss. A desk job with three gym sessions per week is "Lightly Active" (1.375), not "Moderately Active" (1.55) .
Choose honestly. If your TEE estimate feels too high, drop one activity tier and recalculate. It's better to underestimate and adjust upward than to overeat for weeks.
When to Recalculate Your TEE
Recalculate every 10–15 pounds of weight loss, or whenever your activity level changes significantly. Calorie needs drop roughly 50–100 kcal per 10 pounds lost .
If you started at 200 lbs and now weigh 180 lbs, your TEE has dropped by about 100–200 kcal. Your current plan may need to adjust to keep losing at the same rate.

The Optavia 5&1 plan provides 800–1,000 calories daily. It is recommended when your Total Energy Expenditure (TEE) is under 1,500 calories .
What is the Optavia TEE calculator?
The Optavia TEE calculator estimates how many calories your body burns daily using the Mifflin-St Jeor equation. Based on your TEE, it recommends an Optavia plan: 5&1 (TEE under 1,500), 4&2&1 (TEE 1,500–2,000), or 3&3 (TEE over 2,000) .
What's the difference between Optavia 5&1, 4&2&1, and 3&3?
5&1 Plan: 5 fuelings + 1 Lean & Green meal (800–1,000 kcal) for maximum weight loss. 4&2&1 Plan: 4 fuelings + 2 Lean & Green meals + 1 snack (1,100–1,300 kcal) for moderate weight loss. 3&3 Plan: 3 fuelings + 3 regular meals (1,500+ kcal) for maintenance .
How often should I recalculate my TEE on Optavia?
Recalculate every 10–15 pounds of weight loss, or if your activity level changes. Calorie needs drop roughly 50–100 kcal per 10 pounds lost .
What activity level should I choose?
Sedentary (1.2): desk job, no exercise. Lightly Active (1.375): 1–3 days/week. Moderately Active (1.55): 3–5 days/week. Very Active (1.725): 6–7 days/week. Extra Active (1.9): physical job plus training. Most people overestimate their activity level .
💡 Expert Tips for Optavia Success
Tip #1: Use the Optavia TEE calculator at the start and recalculate every 10–15 pounds of weight loss. Your calorie needs shrink as you lose weight .
Tip #2: Be honest about activity level. A desk job with 3 gym days is "Lightly Active" (1.375), not "Moderately Active." Overestimating leads to overeating .
Tip #3: The 5&1 plan (800–1,000 kcal) is for TEE under 1,500. If your TEE is higher, the deficit is too steep and you'll lose muscle, not just fat .
Tip #4: Stay hydrated. Drink 8–10 glasses of water daily to support metabolism and reduce hunger on lower-calorie plans.
Tip #5: Confirm your plan with your Optavia coach or physician. These TEE thresholds are community conventions, not official medical guidance .
