The Claim
When total caloric intake is controlled, low-carbohydrate diets (e.g., ketogenic) result in short-term weight loss but produce long-term weight loss that is comparable to that achieved with high-carbohydrate diets.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you eat the same number of calories no matter what diet you're on, cutting carbs might help you lose weight fast, but after a while, you'll lose about the same amount as someone eating more carbs.

Low-carbohydrate diets (e.g., ketogenic) produce short-term weight loss, but long-term weight loss is comparable to high-carbohydrate diets when total calories are controlled.
What the research says
1 studyStudy: The Role of Carbohydrate Intake in Obesity: Implications For Diet and Weight Management
This study says that cutting carbs can help you lose weight fast, but over time, if you eat the same number of calories as someone on a high-carb diet, you’ll lose about the same amount of weight — so carbs aren’t the magic key for long-term loss.
