Apple Cider vinegar has proven to aid in weight loss ( and also digestion). However, consuming too much will make you vomit. Fenugreek is a vitamin supplement that has also proven weight loss. However, most homemade remedies are also proven ineffective (meaning, they simply just won't work).
You're best bet is the Slim Fast diet. Two shakes for breakfast and lunch, a light, healthy snack and then a healthy dinner. The results from Slim Fast happens within a week. I am on the Slim Fast diet and it has worked wonders.
