I have failed many times trying to lose weight. I've been married to Mr. Skinny for the past 50 years. That man can pack it away and not gain an ounce. Me, no way. I know how hard it is and how defeated we get when that scale refuses to move. Barb135 offers some really good advise. I can only offer portion control (there are marked plates that help with that) and exercise. Just make sure that you enjoy the exercise you select. I'm going to Curves and have started Zumba. I'm really enjoying the Zumba, it's great fun.
Take care.
First off, it's not very kind of your husband to be commenting on your weight. Doesn't he know that it might be an issue for you, without his help?
What types of diet have your tried? Have you incorporated exercise with them?
For diet, concentrate on eating lots of veggies and make sure you have protein with every meal/snack. Protein is the building block for muscle and muscle burns fat.
You might also want to ask your doctor for some simple blood tests to rule out an under active thyroid gland. The tests to ask for are Free T3, Free T4, and TSH. Free T3 and Free T4 are actual thyroid hormones and TSH is a pituitary hormone that's meant to stimulate the thyroid, though it doesn't always work.
You might also want to get checked for insulin resistance, which means that your body doesn't process sugar intake adequately.
Both hypothyroidism and insulin resistance can make losing weight difficult, if not impossible. I know; I have them both and struggle daily with my weight.
