A nurse‑delivered, real‑food low‑energy, low‑carb plan led to far greater weight loss and HbA1c reductions in 12 weeks than usual care. Short‑term cardiometabolic markers and medication use improved too.

RCT
Randomized Controlled Trial
RCT (Randomized Controlled Trial) is considered the gold standard of scientific research. In an RCT, participants are randomly assigned to either receive an intervention (like a specific diet or medication) or a control condition, allowing researchers to establish cause-and-effect relationships more reliably than observational studies. Random assignment helps eliminate bias and ensures the groups are comparable. However, RCTs aren't perfect—they can be expensive, short-term, and difficult to conduct for dietary interventions where people need to change their eating habits for months or years. When evaluating nutrition research, RCTs provide stronger evidence than observational studies, but even RCTs can have limitations in design, funding sources, and how results are interpreted.

Tired of regaining weight after dieting? Research shows that a low-carb diet significantly boosts your daily calorie burn—up to 478 calories for those with high insulin secretion—making long-term weight maintenance dramatically easier.
Low‑carb, dietitian‑guided eating in type 1 diabetes improved HbA1c, time‑in‑range, and cut insulin—without more hypos or ketoacidosis. Short‑term, promising, needs larger trials.
