CLINICAL EVIDENCE & GUIDANCE

Frequently Asked Questions

Why visualize deficit rather than promising exact weight loss?

Human metabolism is adaptive rather than a closed thermodynamic bomb calorimeter. When calories are restricted, NEAT drops and metabolic adaptation occurs. Visualizing the cumulative energy deficit reinforces adherence and habits over arbitrary daily scale fluctuations.

What is the optimal deficit for adults 45+?

For mature adults, a conservative daily deficit of 300 to 500 kcal is the clinical sweet spot. Larger deficits (>750 kcal) trigger muscle catabolism, lower thyroid output, elevate cortisol, and impair sleep quality.

How does protein protect against metabolic adaptation?

Maintaining high protein intake (1.6 to 2.2 g/kg) and lifting weights signals your body to mobilize adipose tissue for energy rather than breaking down skeletal muscle.
