I read somewhere - I think it was on this site, GPs will usually advise people to eat less calories and exercise more in order to lose weight but for people who have hypothyroidism this is not the solution. I am curious to know what is effective and why this is not an effective plan. I eat low carb, low FODMAPS and gluten free but still struggle to lose half a pound! I know weight loss has been discussed before but I am intrigued by this aspect and regardless of what I read don't understand it. This weekend I put on 3 lbs in one day despite walking miles and eating reasonably. I am not diagnosed with hypothyroidism but having a blood test this week and think I do have some symptoms.
