The Claim

Low-carbohydrate and balanced-carbohydrate weight-reducing diets produce little to no difference in average weight loss over three to eight and a half months in overweight and obese adults without type 2 diabetes, with a mean difference of 1.07 kg (95% CI: -1.55 to -0.59) based on 37 randomized trials involving 3,286 participants.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Over a period of three to eight and a half months, overweight and obese adults without type 2 diabetes lose similar amounts of weight on low-carbohydrate diets and balanced-carbohydrate diets.

See the scientific wording

Low-carbohydrate and balanced-carbohydrate weight-reducing diets produce little to no difference in average weight loss over three to eight and a half months in overweight and obese adults without type 2 diabetes, with a mean difference of 1.07 kg (95% CI: -1.55 to -0.59) based on 37 randomized trials involving 3,286 participants, indicating neither diet is superior for short-term weight reduction.

Why this might work

When people eat less food overall, their bodies burn stored fat for energy, causing weight loss. This happens whether they eat fewer carbs or a normal amount of carbs, because the total amount of food eaten is what determines fat loss, not the type of food.

  1. Study: Low‐carbohydrate versus balanced‐carbohydrate diets for reducing weight and cardiovascular risk

    Both low-carb and balanced-carb diets helped people lose about the same amount of weight — just a little over 1 pound more on low-carb, which isn’t enough to matter. So neither diet is really better than the other.
