The problem

Your body is wired to store fat — day and night.

Most products tackle one moment of the day. But fat stays stored because of patterns that run around the clock: by day your metabolism, appetite and blood sugar work against you; at night, poor sleep and evening fat absorption undo the progress.

  1. 01
    Daytime

    Poor fat-cell signalling

    Without TRPV1 activation, fat cells default to the storage state, and a sluggish resting metabolism burns fewer calories.

    Answered byCapsimax® + Sinetrol®

    Gradual-release capsaicin reintroduces the TRPV1 signal; the citrus-guarana complex supports body composition.

  2. 02
    Daytime

    Appetite & blood-sugar swings

    Persistent hunger overrides calorie control, and glucose spikes encourage fat storage and snack urges.

    Answered byGreen tea + chromium + B6

    EGCG helps reduce appetite; chromium contributes to normal blood glucose levels.

  3. 03
    Overnight

    High dietary fat absorption

    Without a binding mechanism, fat from your evening meal is readily absorbed and stored.

    Answered byNeopuntia™

    Binds dietary fat in the digestive tract — studies suggest up to 28% less fat absorbed.

  4. 04
    Overnight

    Poor sleep, stalled fat conversion

    Lack of sleep disrupts cortisol, ghrelin and leptin, raising hunger — and without enough carnitine, fat-to-energy transport slows.

    Answered byValerian root + L-carnitine

    Valerian supports deeper sleep; L-carnitine helps transport fatty acids to be used as energy.

The mechanism

Four steps from storing to burning

Day-only burners leave the night unprotected. Active Slim keeps the fat-release cycle running around the clock — Active Burn by day, Nighttime Burn by night.
