How Diets Help in Weight Loss

Weight loss happens when you burn more calories than you eat — creating a calorie deficit. But not all diets achieve this in the same way.

Some focus on low carbs (like Keto), others on low fat or balanced nutrition (like the Mediterranean diet). What matters most is consistency, portion control, and nutrient balance.

Here’s what every effective diet has in common:

• 🥦 Whole, unprocessed foods

• 💧 Hydration and fiber intake

• 🍳 Sufficient protein

• 🚫 Reduced added sugar and refined carbs

Now, let’s explore the top weight loss diets that actually work — backed by science and real results.
