Intermittent Fasting for Beginners: A Simple Start
July 10, 20266 min readBy Phoenix Wellness Team
What intermittent fasting is
Intermittent fasting (IF) is an eating pattern where you cycle between periods of eating and not eating. The most common protocol is 16:8 — fast for 16 hours, eat within an 8-hour window (e.g. noon to 8 pm).
IF doesn''t change what you eat, only when. Weight loss still requires a calorie deficit.
Why people like it
- Fewer decisions (skip breakfast, done)
- Easier to control total calories
- Less snacking
- Simple to explain to your family
The first week
- Days 1–3: hunger comes in waves, then passes
- Days 4–5: energy stabilizes
- Day 7+: eating window feels normal
Drink water, black coffee, or plain tea during the fasting window. They don''t break the fast.
Who should skip IF
- Pregnant or breastfeeding
- History of disordered eating
- Type 1 diabetes without medical supervision
- Underweight or trying to gain muscle aggressively
A realistic starter plan
- Pick an 8-hour eating window that fits your life (e.g. 12–8 pm)
- Aim for your calorie target inside that window — use the calorie calculator
- Hit your protein (0.8 g/lb minimum)
- Walk daily
- Give it 3 weeks before deciding if it works
Bottom line
IF is a useful tool if it makes eating in a deficit easier. If it makes you binge at night, pick a different structure. Log it in Phoenix and watch your streak.
