Goal

Weight loss

Appetite, body composition, and lasting habits.

The pillars

Each pillar has its own free guide in the Peptiva Centre.

The habits that support this goal

  • Aim for 1.6 to 2.2 g of protein per kilo of body weight (Morton meta-analysis), spread over 3 or 4 meals: it's the lever that preserves muscle during weight loss.
  • A large glass of water 20 minutes before each meal: simple, free, and it changes how hungry you feel.
  • Sleep 7 to 9 hours. A single short night raises ghrelin, the hunger hormone, the very next day.
  • On your plate, eat the protein and vegetables first, the starches after.

Work out your calorie, protein and water needs in a minute.
