Cut down on alcohol. If that is too much to ask, there is evidence to suggest that a glass of red wine does have heart benefits. Avoid beer which is especially fattening. Cocktails can be very fattening depending on what they are made of. The other problem with drinking alcohol is that after a few drinks most people get the munchies and when you’re feeling a little inebriated and hungry you won’t be able to make rational decisions regarding your diet.
