I tried the keto diet for about 6 months and I LOVED it. The only reason I stopped was because it became too expensive (meat is pretty expensive here).
I actually aimed for less than 5-10 grams of carbs when I was on the keto diet, so basically no carbs at all. Although I do tend to do things to the extreme.
For me the hardest part was cutting out sugar, and for the first 4-5 days I had horrible sugar withdrawals (it's a drug, yall!). But once my body had begun the process of ketosis (after about 7-8 days if you're following the diet properly), it was so easy and enjoyable.
But it is a difficult diet to stick to if:
a) you're used to eating processed foods - you will have to learn how to and get used to reading the labels of EVERYTHING in order to find hidden sugar and other carbs in every single product that you eat
b) you're addicted to sugar - the initial week of being on the keto diet will be very uncomfortable because you'll be in sugar withdrawals
c) you're financially constrained, especially if meat is pricey where you live
d) if you know nothing about food nutrition and metabolism in general - you will have A LOT to learn!!! For example you might just presume that all vegatables are okay to eat on the keto diet because they are healthy. This is incorrect as some vegetables are high in carbohydrates.
There is a LOT of information online about the keto diet if anyone is interested in learning about it, but if you seriously want to try it, I recommend that you do just that, read up on it, learn about it, prepare yourself properly for it, and THEN attempt it. It's not just as simply as saying "go on the keto diet".
I also wanted to reiterate that as some others have said, you can't target fat loss to one particular area. You have to have the mindset of "I'm going to lose fat", period.
Also, sure, doing weights in general is excellent for fat loss as it keeps your metabolism going even after you've finished doing the workout. However doing BODY WEIGHT exercises, i.e. using your BODY as the weight, is even better. There are tonnes of body weight exercise routine videos on youtube. And what's better is you generally don't need any equipment, because your own body is the equipment
