So. What's the worst weight loss myth?

Sugar and carbs are the devil, fat makes you fat, sugar automatically gets stored as fat even in a huge deficit, weight lifting will make you bulky

Doing cardio will burn fat.

That eating "healthy" will result in weight loss and the flipside myth -- that there are certain foods that will prevent you from losing weight even if you're at a deficit.

I spent too many years thinking that I had to have a "perfect day" in order for it to count or that there were certain foods that I just couldn't eat.

That carbs make you fat...which is just ironic because carbs are not readily converted to fat...

You can lose *insert ridiculous amount of pounds* in a day/week/month.

Aspartame will make you fat

That fruit is bad because of the carbs & sugar.

That you can only lose weight through clean eating.

paleo/lchf/vegan/organic/no sugar/etc is the only way to lose weight.

If you eat late at night, the calories will not be burned but stored as fat.

Never heard of the starvation mode myth until I got on MFP actually...

So I'd say that carbs are evil.

Not the most horrible, but one that refuses to die is that a person needs to eat a bunch of small meals throughout the day to stoke the metabolic fire.

Anything eaten after 7 p.m. is automatically stored as fat.

Your GI system needs occasional breaks from eating solid food, your body doesn't digest food at night, your metabolism stops at night, you have to reset your metabolism in order to lose weight
