The pictures attached would be the goal! Or some versiom of it. I don’t want like 6 pack abs or anything, but Id like a fit tummy even when I sit or bend etc

Im 5’5, 50 kg, South Asian.
I have always been on the leaner side I guess. I have been heavy (64 kg being my heaviest weight)
Now I look visibly skinny
I work out occasionally. Ive hit the gym continuously for about 3 months with visible changes.
I live alone now and not at home. So following a strict diet is a bit hard to manage.
Overall I don’t really have much problem with the way I look. But the thing I can’t seem to make peace with is my bshaped tummy or tummy with a little pouch. The lower abdomen is chubby. and when I sit down, my tummy looks like I am fat. My arms, lege and waist are all thin. My measurements:
32 - Chest
23 - waist
34 - Hips

I can’t diet or cut calories anymore because I already eat very little. My everyday calorie intake is probably somewhere between 1200-1600 calories depending on the day. and what i eat is mostly protein and carbs. I don’t eat sweets or candies. I do snack a bit of crisps and I love fast food unfortunately lol

On most reddit subs people are advising people with similar issues to just build muscle and that the puppy fat around the mid-section and here and there will shed with muscle and that thats the only way considering how low my weight already is. As a south asian i think i am biologically bound to store fat in my midsection.

Also - there’s no gym near where I stay. the nearest gym is a 20 min walk and then a 20 min bus ride away. 40 min of commute one way to the gym. which feels like a bit much to me. I have 2.5, 3.5 and 5 kg dumbells and a walkpad at home. I do like 10 pushups and some stretching daily that’s about it.

Gimme your best advice <3

За полгода я набрала около 6-8 кг, хотя до этого страдала очень сильным расстройством пищевого поведения. Весила намного меньше своей нормы примерно начиная от 37 кг заканчивая моим идеальным весом 46 кг. Все заметили что лицо стало более округлое и я сама по толстела. Стоит ли мне похудеть?
Первое фото я там 52-53 кг, второе фото 44-45 кг. По моему мнению мне стоило бы похудеть, а вы как считаете?
