Intermittent Fasting and Prediabetes

What you will notice

What you get out of it

This is what changes in your day to day when you give your body well-guided hours without food.

Better blood sugar on your labs

Studies link fasting with lower fasting glucose and better HbA1c.

Why:Fewer hours eating gives insulin a rest, so your body responds to it better.

No crash after meals

That heavy, shaky feeling after lunch fades. Your energy stays steadier.

Why:Smaller blood sugar spikes mean smaller drops afterward.

Fewer sugar cravings

The mid-afternoon sweet tooth loses its grip within a few weeks.

Why:With steady blood sugar, your brain stops asking for a quick fix.

A smaller waistline

Belly fat goes down, and with it one of the biggest drivers of your blood sugar.

Why:Belly fat worsens insulin resistance, so losing it helps.

A plan you can actually keep

No impossible diets: just a clear eating window and reminders so you don't slip.

Why:Consistency matters more than perfection for moving your numbers.

Peace of mind with your doctor

You keep a log of your fasts and meals to show at your next appointment.

Why:Real data helps your doctor fine-tune your plan or your medication.

Frequently asked questions

Does intermittent fasting help with prediabetes?

Studies link intermittent fasting with better insulin sensitivity and lower fasting glucose, especially when you lose belly fat. It isn't a treatment: it's a habit that may help within the plan your doctor sets.

Do I have to talk to my doctor before starting?

Yes, always. Especially if you take metformin, insulin or other blood sugar medication, since some can cause low blood sugar while fasting and your dose or timing may need adjusting. Never change your medication on your own.

What schedule works best for blood sugar?

Many studies point to earlier windows: eat breakfast and dinner early, for example 9 a.m. to 7 p.m. Start with 12:12 and move up to 14:10 if it feels good. Ayúname reminds you so dinner doesn't run late.

What should I do if I feel dizzy while fasting?

Break your fast with some food, sit down, and if it happens again, talk to your doctor. Dizziness, shaking or cold sweats are not something you should push through.

What do I eat during my eating window?

Lead with protein, vegetables, legumes and quality fats. Save the carbs for the end of the plate and skip soda and pastries. Snap a photo of your meals and the AI coach gives you ideas.
