Shrug off the detox tea ads and actively escape from the 'fat burning' supplements section of whichever shady internet site has you cornered we're about to lay down the expert science-backed advice on how to lose 1kg a week safely.

Firstly, how much is 1kg in pounds?

So, 1 kilogram (kg) is equal to 2.2 pounds (lbs) which means that if you were to lose 1kg a week, you'd lose 4 kg (8.8 lbs) a month.

How many calories do you need to burn to lose 1kg?

OK, let's crunch the numbers and then we can get into the nitty-gritty of exactly what you should be doing for healthy weight loss per week.

A pound of fat fat is usually measured in pounds is around 3,500 calories of energy. That's means if you want to lose 1kg weight a week (a healthy and sustainable amount for most, although it's not advised to shoot for more than this) you would need to create a 7,700 calorie deficit (2.2 lbs worth of fat) over the course of a week.

Is losing 1kg a week healthy?

Providing you go through the right guidance with a fine-tooth comb (starting with why you want to lose 1kg a week and if you're in a position to do so in the first place) and follow it to a tee, yes.

Losing 1kg a week isn't going to be right for everyone, though you simply might not have that amount of excess fat to lose in the first instance, and so could end up underweight. Think about the reason you want to lose weight. Is it really going to make you any happier or healthier?

The most important thing to say here is that there is no use in comparing your journey to another's. Every body is entirely unique, and your results really do depend on your starting weight, activity levels, nutrition and sleep as well as other factors such as stress and hormonal fluctuations.

No matter your starting point remember, losing 1kg a week healthily is about remembering that not every week will be the same and trying not to get too stressed about it. Just focus on getting what you can right.

Plus, while 1kg is a healthy weight loss for a lot of women it is just a number after all. Leading your healthiest lifestyle possible will yield the right results for you.

Also, we have to say, pandemic life is, well, stressful. And, if you've found that your health journey or healthy habits have been put on pause because of the various lockdowns or boom and bust approaches to work/life balance with so many changes, then don't stress.

It's easier said than done, we know. But right now, give yourself the freedom to relax your goals slightly.

The best nutrition tips to support healthy eating

Firstly, creating long-lasting healthy habits relies on taking everything in moderation including moderation! That means not falling into the trap of cutting out entire food groups or believing that you'll 'eat this way' until you lose the weight and then 'go back to normal'. It might give you a quick fix and help you lose some weight in a week, but you'll quickly regain it.

Instead, focus on what you can add into your daily diet for health gains like actually using your reusable water bottle and drinking more water more regularly.

3. Fill up with fibre

Whole wheat bread, potato, nuts and grains will keep you feeling satisfied for longer.

When should you eat to lose 1kg a week?

Meal timings are an individual thing. If your schedule has you getting up at 5 am some days and 11 am other days, you're not going to stick to a hard and fast routine, and everyone's days are slightly different. That being said, there are some timings that could help you hit your goals if you're on a 95 schedule from home.

Morning

First thing after waking up

Now's the time to down some water 500ml, in fact according to a German study that found it boosted metabolism by 24% for 90 minutes afterwards. This is due to the fact your body must expend extra energy to bring the cold water down to your core temperature. Easy hack: pop a bottle in the fridge before you head to Bedfordshire so it's ready for when you wake up.

Before breakfast

According to a study in the British Journal of Nutrition, getting a sweat on before you tuck into your morning bowl of oats might be the better choice if you're trying to lose fat as you can burn nearly 20% more if you exercise in a 'fasted' state. 'Your blood-sugar levels are low, so your body has to use fat as fuel for your muscles to work,' says Dean Hodgkin, international fat loss and fitness expert.

However, fasted workouts don't work for everyone. Give it a go and see how it makes you feel.

Breakfast

This might only be for the stronger-stomached person, but breaking your fast with a lean protein be it a turkey breast or a steak, even could be the key to burning more fat, and may well help you on your way to losing 1kg in a week.

Research in the British Journal of Nutrition found eating high-protein meals such as meat and nuts at breakfast time led to a greater feeling of fullness. Try pairing a turkey breast with a handful of almonds a great source of monounsaturated fat that helps to burn belly fat.

Afternoon

Lunch

Lunchtime might be the meal that it's best to up the portion size, according to a study in the International Journal of Obesity that found those who ate 40% of their daily calories from carbs and protein before 3 pm, dropped an average of 11% compared with 9% of those who ate their biggest meal at dinner time.

Lunch might also be the meal that it's best to take your probiotic with. A study in the European Journal Of Clinical Nutrition found that taking the probiotic lactobacillus gasseri for 12 weeks reduced belly fat by a total of 4.6 per cent. Taking your probiotic mid-meal will also 'boost satiety and the feeling of fullness,' says nutritionist Carrie Ruxton.

Mid-afternoon

Rich in plant compound ECGC, green tea can promote the burning
of fat. In fact, three cups a day could cut your weight by nearly five per cent, says a French study. Plump for matcha green tea powder it can increase the bodys rate of calorie burn by up to 40 per cent.

Evening

Dinner

Best to dish up early, if you're trying to lose fat, as the extra hours before bed not eating will help your body digest and get into a rest state before sleeping. To maximise fat loss, eat dinner early, then fast for around 14 hours until breakfast the next day.

After dinner

After youve had dinner, it could be beneficial to go for a 10-minute walk as light post-meal exercise can lower blood sugar and stop you from storing fat. If you don't live somewhere where you can venture out safely and at a social distance of two metres to others then this yoga pose is also known to relieve indigestion: lie on your back with your hands on your knees, exhale and hug your knees to your chest; gently rock from side to side for 5-10 breaths.

Bedtime

Those who consistently get poor quality of sleep are more likely to suffer major weight gain so try to aim for at least seven hours each night to keep cortisol levels in check. 'This [cortisol] hormone regulates appetite says trainer Christianne Wolff. 'If it's out of sync, you'll never feel full,' she explains.

The takeaway?

Before embarking on any "weight loss" plan get clear on why "weight" dominates your goal and don't forget: weight is not a synonym for health.
