A friend of mine who learn that his wife was cheating him lost 3 kg overnight!
How many kg do you want to lose? Get cheated as many times as you need to reach the desired weight. Just keep in mind that every sequential cheating may have lesser impact on weight loss. So don't get used to it if you wish to get slim fast. Every next cheating of your spouse should be a shock to you. So, for better results, restart trusting your spouse immediately after every his or her cheating:-)))
