Which are some simple thai cuisine, less in calories, recipes with fruits and nuts that will help me in my heavy smoking and obesity?

Fruits and nuts would help you to reduce body weight, but the benefits of that would be counterbalanced if you smoke heavily. So at the end, you wouldn't find much benefit from eating healthy diet. Fruits are very powerful in burning body fat and removing toxins from the body. You can go for healthy and exotic thai fruit salad by mixing freshly cut pineapple cubes, papaya, lychee, star fruit, water melon with 1/2 cup of coconut milk and 2 tbsp of brown sugar and 1 tbsp of lime juice. I think you can replace brown sugar with plam sugar as palm sugar made out of palm candy helps to reduce body weight and body heat, and at the same time, it won't increase your blood sugar as much as the normal refined sugar does.

You can also try another spicy thai fruit salad with 1 cup of finely cut fresh fruits like apple, pineapple, pomelo, grape, guava and other fruits of your choice. Then mix the fruits with 1 cup of grated carrot and 1 cup of finely chopped tomato. To this add 1 1/2 tsp of lime juice, 1 tsp of roasted peanuts and 2 tsp of palm sugar. Mix well and add salt and ground pepper to taste. Juicy fruits like grapes, papaya help a lot to flush out accumulated toxins from body. Once the toxins are flushed out of the body, then the body's metabolism would stabilize.

Moreover, I think it would be beneficial for you if you quit smoking. In order to reduce the craving, you can frequently have small amount of hot black tea mixed with palm sugar and 1/4 tsp of fresh ginger paste. This would not only help you to reduce body weight, but would also help you stop smoking.

Moreover, you need not reduce your intake to two meals a day. Instead, you can replace your entire third meal with fruit salads and juices. There are plenty of slim fast drinks in the market, but all are loaded with sugar and wouldn't give you much results.
