Should i eat less carbs or burn more calories?

Who told you this and why are you listening to this person?

You don't need to cut carbs to lose weight, you only need to eat accurately at a deficit. I'm assuming this is some kind of weightloss program you signed up for which isn't customized for you at all? If so I would recommend switching programs or simply cooking your own foods and tracking calories.

I tried low carb once. The only difference I noticed was how much I missed having sandwiches for lunch while I sat there eating my salad.

By all means try low carb if you want, but it's not really necessary. Especially if you're only trying it because you didn't lose weight for one week. Weight loss isn't linear - some weeks we lose, some we stay the same, some we gain. One week of no weight loss means nothing. After 3 or 4 weeks you might want to start thinking about changing things up.

Also if you're only weighing once a week, there's a chance you did lose weight but just fluctuated on the day you weighed. This happens all the time, some days I'll be 2lbs heavier one day than I am the day before and after. So yeah, don't worry about one week of not losing weight.

I would figure out how many calories all of their meals add up to, if they are below the deficit you need to lose weight don't change a thing. Drink plenty of water and understand your body is not a math problem, but a living and fluctuating organism. If your meals have too many calories in them to be a deficit at your current weight then sure you can cut carbs or up your walking, or just accept a less than 1000 calorie deficit which is what it takes to lose two pounds in a week.

The only reason to cut something is if you're having to much of it. Over the last 25-30 years or so, consensus is that we as a population are consuming less fat and more carbohydrates (mostly simple).

Carbohydrates? You need. Them.

I recommend worry about exercising and getting active and diet later. What you eat matters, but not as much as getting strong enough to do meaningful workouts.

That's up to you. Some people do well on low carb, while others struggle. I personally found that I got better results when I went from high carb and low fat to low carb and high fat. Here's a site on keto if you're interested in going down that path.

Beware that you will get people jumping on you for even thinking about going low carb. It's inevitable.

1 kg a week is a really good rate of loss (in fact it might be a bit too fast if you're already a healthy weight). Weight loss isn't linear though, so it's not unusual to have a week where you don't see any change on the scale. That doesn't mean you have to change what you're doing. Just carry on and you'll probably lose a bit the next week. You don't need to cut carbs anyway, as you've already proved with your previous loss.

this.

when you cut carbs you can trick your body into losing, as your glycogen stores that also hold water will diminish a bit, so the water weight in your body is lower. As soon as you up your carbs, weight (water in glycogen stores) typically goes up. So smartly they told you to do this and you saw scale results, but it was not all fat.

You need about 4 weeks to be able to tell whether something is working for you. If your program is stalling you for 4 weeks or more it's time to look at where might be a problem, otherwise stick to it and you will see a loss the week or two after.
