Don't worry, my answer is not surgery...
Most people who are fat are made to feel that it is because you lack will power, you are lethargic and a weak person. But that is definitely not true.
It is your your hormones which have made you fat and keeping you fat. Unless we make correct diagnosis and and create a diet and lifestyle plan to correct that hormonal abnormalities you will not be able to lose weight for long term. Most diet fails because they are low calorie and low fat. Instead of correcting metabolism, they make you feel low energy or makes you feel excessively hungry.
To achieve weightloss - think long term. Weight loss achieved over short term, always comes back.
There is a general approach and a specific approach as per individual patients metabolic profile.
Try this general approach for 4 weeks. If this works then continue. If this is not enough then consult personally for further assessment and customised approach. With customised approaches people over 100-150 kg are also losing weight for long term.
1. Do not eat anything sugary or sweet. ZERO sweetness in diet.
2. Eat PLENTY of salad in lunch and dinner along with other foods.
3. Do not drink any liquid calorie like cola or fruit jucies.
4. At least 30 min of exercise every day of any kind
