Does beetroot help with weight loss? What the research does and doesn't show

The evidence doesn't support beetroot, in any form, as something that produces weight loss. We didn't find a single published trial that measured body weight, fat mass, or fat loss as an outcome after giving people beetroot juice or powder. The closest available research tested a proposed underlying mechanism instead — and found nothing.

What the evidence doesn't support

It doesn't support beetroot as a fat burner, an appetite suppressant, or a weight-loss aid in any direct sense — no trial we found actually measured weight or body fat change after beetroot supplementation. It doesn't support the idea that beetroot's dietary nitrate activates brown fat (a type of fat tissue that burns more energy than ordinary fat) in a way that would help with weight; the one study that tested this directly found no such effect. And it doesn't support extrapolating from beetroot's other research — on blood pressure or exercise performance — to weight loss, since those trials didn't measure it either.

What the trial found

A randomized, placebo-controlled crossover trial set out to test one specific, plausible mechanism: whether dietary nitrate from beetroot juice activates brown adipose tissue, a metabolically active fat that some research in animals has linked to burning more energy. Thirteen older adults with type 2 diabetes drank either 140 mL a day of beetroot juice (providing roughly 12.4 mmol/L of nitrate) or a low-nitrate placebo drink for 14 days, with brown fat activity measured by MRI and infrared imaging after a cold-exposure test designed to trigger it. The beetroot juice clearly raised nitrate levels in the blood, confirming people actually took it — but it produced no measurable change in brown fat tissue fraction or activation compared with placebo. The trial's own conclusion was direct: 14 days of nitrate supplementation did not increase brown fat activity in this group.

This is a small trial (13 people), in a specific population (older adults with type 2 diabetes), testing a mechanism rather than weight itself. It's the only human research we found connecting beetroot to anything resembling a fat-metabolism outcome, and it came back null.

Questions people ask

Does beetroot help you lose weight?

No trial we found tested this directly. The one related study tested whether beetroot juice activates brown fat, a proposed weight-related mechanism, and found no effect after 14 days.

Is beetroot good for weight loss?

There's no direct evidence either way, since no trial measured weight change after beetroot supplementation. The one mechanism study available found no effect on brown fat activation, which weakens rather than supports the idea.

Does beetroot juice burn fat?

The one trial testing a fat-burning-adjacent mechanism (brown fat activation) found beetroot juice had no measurable effect on it, despite clearly raising nitrate levels in the blood.

When to talk to a doctor

Beetroot is not a treatment for obesity or a weight-loss strategy, and nothing above supports using it as one. If you're working on weight management, that's a conversation for a doctor or registered dietitian, who can weigh options with actual evidence behind them for your situation.
