Drinking this before breakfast may help you lose weight, have great skin

Celebrities like Jennifer Aniston, Hilary Duff and Christie Brinkley all swear that lemon water is the perfect way to start the day.

Hot water with lemon juice added in, there are no rules about how one makes it, but it contains a load of vitamins.

It's supposed to lift your mood, energy levels, improve your immune system and your metabolism - helping you lose weight.

According to experts half a lemon contains 25 per cent of your recommended daily intake of the vitamin - which can help improve cardiovascular and eye health, as well as reducing our risk of things like stroke and cancer.

Talking to The Sun, Dr Sarah Brewer said that citrus fruits contain antioxidant polyphenols and vitamin C which protect cells from the damaging effects of free radicals (the things that cause cancer and wrinkles).

The doctor further added that vitamin C also helps to lower cholesterol levels by promoting the conversion of cholesterol to bile acids.

And it helps us stay hydrated

Kicking off the day with a very low-calorie, refreshing drink can give us a little clarity about how we're genuinely feeling.

Studies say that intermittent fasting is great for weight loss. It involves reducing the pocket of time in which you eat to around eight hours, allowing your body to fully digest what you've eaten for the other 16, and get to work on any excess stores of fat.

During those fasting hours, you're supposed to only consume fat-free, sugar-free drinks like black coffee, tea and water. But a hot lemon water is also a good caffeine-free alternative. However it cannot detox the body.

Notably, even though lemons genuinely increase your metabolic rate and can help to keep blood sugar balanced it's not going to help you lose any more weight than a glass of regular water would.
