Hi Op,
I am still bf my 20 month old and for the first year, I found losing weight quite difficult, I lost weight initially after giving birth...then it seemed to creep back on. I put on about 2 stone, but I don't believe that was from breastfeeding alone.
Looking back, I was not as active as I had been, covid happened and we were not getting out as much, I was snacking alot, eating quite alot of biscuits and chocolate.
My appetite did seem to increase whilst bf which I read can happen, so whilst I was eating mostly healthy meals, my portions were massive!
I have lost the weight now, slow and steady, and am now back to my pre pregnancy weight.
I don't do any fancy, restrictive diets. I just eat roughly between 1500-1600 calories a day, I am always in a deficit so the weight just naturally comes off. I find it surprising easy to keep to and rarely feel hungry during the day after my meals. I use my fitness app to record things but tbh, I know alot of things off by heart now, so don't use everyday.
I can recommend the Weight Watchers app too, I did it for 3 months and it really kick-started my weight loss. I used the plan for breastfeeding mothers too so it gives you extra points.
If you want to lose it, you will do it. Give yourself a realistic goal and don't rush it. Those kind of diets rarely work long term. If you want to breastfeed, you should. I personally wouldn't rule bf out just to lose weight through a restrictive diet.
