Extreme plans create noisy feedback
Large, rapid changes can affect sleep, energy, digestion, training and hunger at the same time. When everything changes, it is difficult to identify the cause of a result or side effect.
Simple routines create cleaner signals
Keep meals, movement and sleep reasonably stable. Add only one new supplement at a time and track how you feel.
Progress is not linear
Daily changes do not always reflect fat loss or gain. Hydration, food volume, sodium, stress and many other factors can shift scale weight.
Use Fitvia as one variable
If you decide to try Fitvia, keep the rest of the routine stable, follow the label and record tolerance. Stop if the product creates unwanted effects.
