Other things that could cause weight gain (disease)?

You need to log every mouthful and drink for a month or so. Watching potion sizes and snacks etc. Once you have done that you can look back and see if you are eating more than your body can burn.

Remember when logging exercise that the calories allocated can be a bit overinflated.

As to the thyroid issue, most articles that are scientifically based say that with thyroid issues you are talking about a 20 pound gain, not 100's of pounds.

It really is calories in and calories out.

My mums got a thyroid problem, I can't remember if it's over active, or under active, but I do know she finds it really difficult to lose weight, as has already been suggested, log everything for a month, if you are still having difficulties then go and see a gp and ask to be tested

It never hurts to be checked out by your DR! Esp. I think when trying to lose weight it can probably be helpful anyway to discuss things, and see where you are at?

Vitamin D deficiency is another potential cause of difficulty losing weight. So, it really may be worthwhile to go in to your general doctor and have a full blood workup done.

With most conditions (thyroid, low testosterone, low vitamin D, etc), weight gain/difficulty in losing is only one of the symptoms. Generally they are accompanied by feelings of exhaustion and lethargy, feeling cold in normal temperatures, sleep issues, etc. So if weight loss is the only symptom, I'd suspect that it's more a case of improper estimation of what you're eating. Still, never hurts to rule out these potential conditions.

So now I am eating healthy and much, much, much less AND exercising every day.

Something should be happening right?

I would talk to your doctor, because why take chances?

Some medications can also cause weight gain.

I wasn't logging till last week so don't bother checking the diary So how do you know how many calories you were eating?

I'd put money on you eating more than you think that is far more likely than a medical issue. Without an accurate diary we can't offer specific advice but you need to weigh all solids measure all liquids and make sure you're using accurate entries on the database

Holy crap! You ate in one day what I eat in a week!

My boyfriend eats like that and he's got the fat to prove it. Except for potatos (usually of the fried variety) and the extremely rare (and butter drenched) corn-on-the-cob, the man doesn't even touch fruits and veggies. He eats nothing but total crap. He likes his beer, too.

What made you decide to lose some weight? I don't suppose it was anything your wife or girlfriend said or did? (Like, that I could maybe use, lol.)

Lots of people don't count calories and it certainly isn't necessary to lose weight. It is enlightening, though. The first time I counted, I ate more than I thought. The next time I counted, I ate way less than I thought. You might want to try it for just a couple weeks and see how it works out. But you might not. Either way. No skin off my nose.

You can eat less calories bu the wrong macro's at the wrong time and not make the kind of progress that you would expect. First, talk to your doctor Second, if you doctor approves... Ditch all those carbs first thing in the morning! That's about the worst time to have them, except maybe right before bed. Instead, have 2 boiled eggs. For a mid-morning snack, try a high-protein meal replacement bar. Most of your snacks, while maybe low calorie, may be the wrong kind of macronutrients. Instead, try either 1/4 cup of tree nuts, a yogurt (not fat-free, get the real thing), or a high-protein meal replacement bar.

Even better, try making breakfast your big meal of the day. I am a big fan of the meat-and-nuts breakfast. I.e. lean meat of some type, accompanied by a serving of tree nuts. It's a great way to start your day.

And while I hate to tell you this... alcohol has a long-lasting effect on your metabolism. Even once a week is enough to cause problems.

Ask your doc about the idea of doing 1800 calories, with 40% protein, 40% carbs, and 20% healthy fats. Then try to make each meal around those same levels. Don't eat carbs by themselves unless you know what you're doing and it's to fuel exercise.

Again, everything with your doctor's approval of course

It looks like you lost weight. Are those weights daily? What is the average weekly weight loss & when did you start? & if you are eating a lot of food that is processed & full of sodium you'll be retaining water

let us know! interested to see what you find out

Waiting for test results in about a week.

She actually suggested looking into weight loss surgery - she said about 85% of her clients who have done it have kept off the weight ten years later.

You're looking for the easy way out. If you're thinking about weight loss surgery. Try being on a calorie deficit for at least a year.
