I find when I stick to little or no carbs my weight loss does increase compared to when I do have carbs. I'm not as bloated and do see a significant difference in inch loss around my stomach, even without exercise.
Although that doesn't mean I never have carbs. For me, my "diet" is a life change that I will continue for the rest of my life, as my relationship with food has never been healthy. So I mainly try to focus on having the right carbs, but control my portions. That's quite difficult, as I have an affinity with stodge
I was referred to a dietician at the beginning of my journey and she encouraged to have a balanced diet, which included some carbs.
I wouldn't say my weightloss is fast, and I'm going to the gym up to four times a week, and play netball twice a week.
