If you want to give your metabolism a boost, there are several ways to do it, though some are far more realistic for everyday life than others.
Dr Turner Osler, an emeritus professor of surgery and research epidemiologist at the University of Vermont, believes some hacks really work for raising your basal metabolic rate.
The retired academic surgeon turned epidemiologist has spent years researching how people can lead healthier lives through simple changes.
While drugs like thyroid hormones and amphetamines can technically increase metabolic rate, they come with serious downsides.

Thyroid medication risks heart rhythm problems, bone loss and muscle wasting, while amphetamines fell out of favour decades ago due to addiction issues and cardiovascular complications.
So what's the best option if you want a chemical boost without the side effects? Caffeine.
Dr Osler told GB News that your morning coffee can make a difference, with a modest 100mg dose of caffeine – roughly what you'd get from a single cup – temporarily raising your metabolic rate by 3-4 per cent.

For those who really love their coffee, the effects are even more pronounced. Heavy caffeine consumers taking in around 700mg daily could see their basal metabolic rate climb by as much as 10 per cent.
Many of us are already adopting this approach without realising the metabolic benefits. That said, there's an even safer method that doesn't require any substances at all.
Dr Osler points to something called non-exercise thermogenesis, or NEAT, as a brilliant alternative.
This involves raising your metabolic rate through physical activity that doesn't quite count as proper exercise, like taking regular movement breaks while working at your desk.

He noted that swapping your standard office chair for one with a slightly wobbly seat can increase your metabolic rate by up to 30 per cent, as was demonstrated in one study.
This matters because so many people spend hours sitting down each day, and traditional supportive chairs actually keep our metabolic rate at rock bottom by removing almost all muscular activity.
Dr Osler said he applauds "bringing more attention to safely helping people lead healthier lives by simply introducing more movement into their daily routines, no gym membership or supplements required".
