I've been on strict diets like eating black beans with no salt and raw vegetables and salads and exercised so hard and I don't loose weight what could be a better way to loose weight?

Have you talked to your dr? Or maybe a nitritionist?
And if you're excercising, are you maybe gaining muscle mass and losing fat? If that's the case, muscle weighs more than fat so tat would be why you're not losing weight.

Your diet should be healthy and well-balanced. Be careful with strict diets. Make sure that you're eating enough of everything you need- vitamins, protein, good fats, good carbs, etc.

What's your workout routine?
How old?
How much do you want to lose?
How long have you been doing your current routine?
