Understanding Different Diet Trends

Popular diet trends in 2025 reflect a growing focus on health, sustainability, and personalization. Here’s an overview of some of the major diets, their benefits, and drawbacks:

Keto Diet

• What it is: A low-carb, high-fat diet designed to put the body into ketosis, where fat is burned for energy instead of carbs.

• Pros: Can lead to rapid weight loss, improved energy, and appetite control.

• Cons: Highly restrictive, difficult to follow long-term, may cause nutrient deficiencies, and side effects like “keto flu” and constipation. Not suitable for people with certain health issues without medical guidance.rush+1​
