Dr. Karishma Ahuja, Law of Attraction trainer, hypnotherapist and Metaphysical Counsellor lists down 6 ways to use the power of your mind for your Weight

Stop saying, I want to lose weight
We generally associate finding with losing. What you lose, your subconscious mind has the natural instinct to make you look for. So saying, I want to lose weight, will actually make you put on more weight because that’s what you are unknowingly asking the subconscious mind to do. Instead of lose, use words like I want to get fit and flexible, I wish to reach my ideal body weight and so on.
