People who want to lose weight are particularly susceptible to all sorts of tips, tricks and advice being offered. Good advice isn’t easy to find – and should be carefully weighed. Fifty years ago, fat was demonised, then carbohydrates became taboo. Nowadays sugar is treated like poison, and if you don’t get enough protein, then nothing else will work. Which statements are true and which ones are false?

1. Eating at night makes you fat

Whatever you eat after 6 p.m. goes straight onto your hips – or at least that’s according to a widely held belief. It’s a myth. What really matters isn’t when we eat, but the amount of calories we consume throughout the day. 

If you maintain a calorie deficit, you will lose weight even if you eat dinner late. The only consideration is that your dinner shouldn’t be too difficult to digest. Lighter fare in the evening makes falling asleep easier.

2. A trip to the sauna melts the fat away

Regular sauna visits can help prevent colds, but you can’t sweat away your fat deposits as easily. That would be too good to be true. The verdict: myth

Any reduction in weight that you may notice post-sauna is simply down to water loss. When you sweat, you lose water weight but not fat. In fact, losing such a substantial amount of fluid may even stimulate your appetite, which is why it’s important to drink plenty of water or unsweetened tea during and after your sauna session, to stop your stomach from sending out a false alarm.

3. Fat and carbohydrates make you gain weight

Fatty foods have been demonised for a long time. However, the healthy fats found in nuts, avocados and fish are essential for your body, and can even help you lose weight by making you feel fuller for longer. 

Carbohydrates are also not your enemy – on the contrary, they are part of a balanced diet. Wholegrain products, pulses and vegetables supply you with energy and important nutrients. It’s the quality that counts, rather than going completely without. This is a myth.

4. Two meals a day are enough

Some people say that grazing between meals staves off hunger and helps you lose weight, while others claim that having just two meals a day is the healthiest option. So which assertion is correct? 

The bottom line is that losing weight doesn’t depend on the number of meals you eat, but on how much energy (calories) you consume throughout the day, and how much you expend through movement and work, including mental tasks.

We do know that blood sugar spikes after every meal, causing insulin to be released, which promotes fat storage. So constantly grazing on food may not be helpful. But what matters is the overall picture. You have to find out for yourself what works best for you – there is no right or wrong.
