Before changing your routine dramatically, do not forget to consult a doctor or dietitian. The main task of a specialist is not just to help get rid of excess weight, but to determine why you gained weight, and to choose a diet that won’t harm the patient.
Here are some tricks, which you should follow on a daily basis to lose weight and stay fit for a long time:
30 minutes of physical activity every day;
Purchase food only from the shopping list;
Eat products rich in protein and fiber;
Avoid baked foods such as cookies or desserts;
Get rid of junk food (chips, crackers, burgers are high in calories, contain a lot of salt, sugar etc.)
