Why Am I Not Losing Weight in a Calorie Deficit?

Direct Answer: The most common reason is hidden calories. Salad dressings, cooking oils and "healthy" snacks add 300–600 kcal/day without you noticing. Use Pic2Chef to scan your actual food instead of estimating — AI-detected calories reduce estimation errors by 70%.

Reason #1: Hidden Calories You're Not Counting

Studies show that people underestimate their caloric intake by an average of 20–40%. The biggest culprits aren't junk food — they're foods we think are healthy.

• Olive oil (1 tbsp): 119 kcal (not 60 as most people think)
• Avocado (1 whole): 234 kcal
• Salad dressing (2 tbsp): 130 kcal
• Peanut butter (1 tbsp): 94 kcal

Reason #2: Metabolic Adaptation

When you eat less for weeks, your body adapts by slowing metabolism by 10–20%. This means your original calorie deficit is no longer a deficit.

Reason #3: Not Eating Enough Protein

Protein has a thermic effect of 25–30%. Low protein also causes muscle loss, which further slows metabolism.
