Chapter one · We listen

The journey starts
with a blank page.

The first session has no scale and no judgment. We sit and listen: When do you eat? How many hours do you sleep? What have you tried before that didn’t work? What do your lab results say? Then this page gets filled in — with a plan written just for you, reviewed by Dr. Diaa before it reaches you.

Chapter two · Choose your path

The same journey… at three speeds.

Every nutrition plan is designed and reviewed by Dr. Diaa Eldeen, and every package includes a call at the start of your follow-up plus daily follow-up — the difference is in the level of follow-up, how quickly you can reach us, the number of psychological sessions, and training follow-up.

Our goal at DeFit isn’t just a change on the scale — it’s your long-term health.

Important: every case is first referred to an internal medicine physician to decide on the right treatment; nutritional follow-up runs alongside that treatment, not instead of it. These are real laboratory results from our members, and results vary from person to person.

Nutrition myths

What you’ve heard… is probably wrong.

01
Carbs cause obesityA calorie surplus is the cause. Complex carbs are part of any balanced plan.
02
Detox cleanses the bodyYour liver and kidneys do that for free. Juices just add sugar.
03
No eating after 8 p.m.What matters is your total for the day and the quality of your food, not the time.
04
The faster you lose weight, the betterFast weight loss comes from muscle and water — and it comes back faster.
