Why Hydration Matters for Weight Loss
Water is involved in virtually every metabolic process:
- Fat metabolism (lipolysis) requires water
- Dehydration slows metabolic rate
- Thirst is often mistaken for hunger
- Water helps eliminate waste from fat breakdown
How Much Water Do You Need?
General guideline: Half your body weight in ounces, plus more for exercise and GLP-1 medications.
- 200 lb person = 100+ oz daily
- Add 16-24 oz per hour of exercise
- GLP-1 users should increase by 20-30%
Signs of Dehydration
- Dark urine
- Headaches
- Fatigue
- Dry mouth
- Constipation (especially on GLP-1s)
- Hunger despite recent meals
Practical Hydration Tips
- Start your day with 16 oz of water
- Keep a water bottle visible at all times
- Drink before meals (aids satiety)
- Set hourly reminders
- Flavor with lemon or cucumber if plain water is boring
The Bottom Line
Adequate hydration supports every aspect of weight loss. It's simple, free, and often overlooked. Make drinking water a conscious priority.
