For my wife, for money! I suggest you don't expect too much. Losing weight is like climbing Mount Everest. This requires willpower, lasting willpower, so don't worry! Advise your wife, in fact, she is not fat, fat is also very cute, you can lose weight, you can help her, but the online things are still French? It is even harder to try!
What's the problem now? Help her reduce the fat and oil in her food. Daily exercise, without a lot of gravity exercise, is aerobic relaxation exercise. Don't eat if you are not hungry at night, and be careful not to overeat at at ordinary times!
As a woman, it is natural to love beauty. Don't discourage her, guide her to the right realistic direction! I believe that she also believes that she is a good husband.
