DON'T KILL YOURSELF FOR YOUR DIET
The best strategy for achieving and maintaining a healthy weight in otherwise well people is to eat a variety of foods, including fruits and vegetables, and get lots of exercise. Meeting with a nutritionist can be helpful. It is not just the quantity of food, but also the quality. Before the visit, it is often recommended that you keep a record of everything you eat on three different days including at least one weekend day.
TRADEOFF
You don't want to sacrifice your life for your diet. On occasion, you will find yourself unable to eat healthy. Whether this is because of lunches with your team at work, birthdays, or special occasions, there will be events that you just can't (or don't want to) eat healthy. A diet will feel overwhelming if you have to sacrifice special events in your life. The way I combated this was to exchange a day that I was not going to diet on the weekend. In other words, if I didn't diet on Tuesday, for example, I would diet on Saturday, instead.
