Optavia TEE Calculator 2026: How Many Calories Should I Eat on Optavia? Free Plan Selector ★★★★☆

How This Optavia TEE Calculator Answers "How Many Calories Should I Eat on Optavia?"

The most common question for anyone starting the Optavia program is "how many calories should I eat on Optavia?" Our Optavia TEE calculator 2026 provides the answer instantly using the scientifically validated Mifflin-St Jeor equation. Total Energy Expenditure (TEE) is the number of calories your body burns each day based on your age, gender, weight, height, and activity level. Once you know your TEE, you can determine which Optavia plan will create the right calorie deficit for your weight loss goals.

How Your TEE is Calculated (Mifflin-St Jeor Equation)

First, we calculate your Basal Metabolic Rate (BMR) - the calories your body burns at complete rest just to maintain basic functions like breathing, circulation, and cell production. For males: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5. For females: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161. Then, we multiply your BMR by your activity factor: Sedentary (1.2), Lightly Active (1.375), Moderately Active (1.55), Very Active (1.725), or Extra Active (1.9). The result is your TEE - the exact number of calories your body needs daily to maintain your current weight.

Optavia Plan Selection Based on Your TEE

TEE under 1,500 calories → Optavia 5&1 Plan (800-1,000 calories daily): This is the most aggressive plan for maximum weight loss. It's recommended for smaller individuals or those with lower metabolic rates. The plan includes 5 Optavia fuelings (bars, shakes, soups, or puddings) plus 1 "Lean & Green" meal (5-7 oz lean protein + 3 servings of non-starchy vegetables). Creates a 500-700 calorie deficit leading to 1-2 lbs weight loss per week.

TEE between 1,500 and 2,000 calories → Optavia 4&2&1 Plan (1,100-1,300 calories daily): This balanced plan for moderate weight loss. Includes 4 Optavia fuelings, 2 Lean & Green meals, and 1 optional snack. Best for individuals with moderate daily activity who need steady energy throughout the day. Creates a 400-800 calorie deficit.

TEE above 2,000 calories → Optavia 3&3 Maintenance Plan (1,500+ calories daily): This plan is designed for weight maintenance, highly active individuals, or those who have completed their weight loss journey. Includes 3 Optavia fuelings and 3 regular meals. Creates a 200-500 calorie deficit for gradual weight loss or maintenance.

Example Calculation: How Many Calories Should I Eat?

Example 1 - Female, age 35, 70kg (154 lbs), 165cm (5'5"), moderately active: BMR = (10×70)+(6.25×165)-(5×35)-161 = 700 + 1,031 - 175 - 161 = 1,395 calories. TEE = 1,395 × 1.55 = 2,162 calories/day. Recommended Plan: 3&3 Maintenance Plan (1,500+ kcal). Calorie deficit: 662 kcal/day → ~1.3 lbs per week.

Example 2 - Male, age 45, 100kg (220 lbs), 178cm (5'10"), lightly active: BMR = (10×100)+(6.25×178)-(5×45)+5 = 1,000 + 1,112 - 225 + 5 = 1,892 calories. TEE = 1,892 × 1.375 = 2,601 calories/day. Recommended Plan: 4&2&1 Plan (1,200 kcal). Calorie deficit: 1,401 kcal/day → ~2.8 lbs per week.

Common Mistake: Overestimating Activity Level

Most people overestimate their activity level! If you have a desk job and exercise 3 days per week, you should select "Lightly Active" (1.375), not "Moderately Active" (1.55). Overestimating your activity level can add 200-300 calories to your TEE calculation, which may lead to selecting the wrong Optavia plan. A person with a desk job who exercises 3 days per week burns significantly fewer calories than a construction worker or personal trainer. Be honest about your true activity level for the most accurate results.

How Often Should You Recalculate Your TEE?

Recalculate your TEE every 10-15 pounds of weight loss, or whenever your activity level changes significantly. As you lose weight, your calorie needs decrease by approximately 50-100 calories per 10 pounds lost. For example, if you started at 200 lbs and lose 20 lbs to 180 lbs, your TEE will decrease by about 100-200 calories. This means you may need to adjust your Optavia plan or reduce your calorie intake to continue losing weight at the same rate. Our calculator includes weight in the formula, so simply re-enter your current weight for updated results.
