Apple cider vinegar has excellent blood thinning property, but I doubt whether it can help you loose weight. But, you can try it anyway if you are not on any blood thinning medications. For losing weight, it would be better if you follow vegan diet consistently as vegetables help to burn calories. Moreover, cow's milk contain some unwanted growth hormone which are not needed for human beings. You can read Dr Robert Cohen's book "No Milk". He details how avoiding dairy products can help in many ways. In general, try to include good portion of fruits that are good for health and also for burning fat. One of the tried and tested way is to replace one meal completely with a bowl of fresh juicy fruits.
Take care that you don't include canned fruits, as the nutritional benefits and the effects of canned fruits are different from that of fresh fruits. Another effective food for removing unwanted toxins and reducing body fat is oats. Oat is actually a wonder food and many people just have it for breakfast. Just try to have oats three times a day for 2 days continuously every week. You will find a considerable reduction in your body weight. For morning breakfast, you can make a sweet oats porridge, and for lunch and dinner, make a spicy vegetable stir fry and mix 2 or 3 cups of cooked oats and have it. The meals would be tastier and you can lose weight without any hassle. You can definitely include apples daily, as they are loaded with lots of nutrients, minerals and apples also help to strengthen bones, especially for women. But apple cider vinegar has blood thinning properties and you don't want to get into unwanted trouble by having it daily.
