Energy balance
Low-carbohydrate diets (LCD) do not provide superior weight loss or glycemic control compared to low-fat diets (LFD) in the medium-to-long term; observed benefits are primarily driven by weight loss rather than carbohydrate restriction itself.
If your goal is weight loss or better blood sugar control, you do not need to restrict carbohydrates specifically. Focus on creating a caloric deficit and choosing nutrient-dense foods. Long-term success depends on adherence and weight loss, not on avoiding carbs.
Solely lowering carbohydrate intake does not, in the medium/long term, reduce HbA1c for T2D prevention or treatment... Under controlled feeding conditions, LCD are not physiologically or clinically superior to diets with higher carbohydrates for weight-loss, fat loss, energy expenditure or glycaemic outcomes; indeed, all metabolic improvements require weight loss.
Why this rating
Based on multiple meta-analyses and RCTs cited, though the review notes publication bias and quality issues in some meta-analyses.

- Long-term adherence to low-carbohydrate diets, particularly those high in saturated fats, is associated with increased LDL-cholesterol, increased cardiovascular disease risk, and increased mortality.Moderate
- Low-carbohydrate diets can lead to micronutrient deficiencies, including thiamine, folate, vitamin C, magnesium, calcium, iron, and iodine, due to the avoidance of whole grains, fruits, and starchy vegetables.Moderate
