Best diet ever?

I've been dieting and doing so many things to maintain my weight, but still putting weight. Two years ago I had a transformation and lost 30kgs then gained 15kgs back. I'm 36 Y/O, 5'4 tall and 83kgs now. Give me some diet plans or tips please.

I stopped drinking soda pop and also stopped eating foods containing gluten.  I lost 40 lbs. And have kept it off for years.

Here are some methods that you can consult:

First, reduce totally the foods that cause weight gain.

1. Sugar: Sugar is widely known as the main reason for obesity in daily diet. When the consumption of these foods is high on a daily basis, the possibility of obesity is significantly increasing
   
2. Carbs: Refined carbs are the main reason why you feel hungry more often. Consequently, you will consume more foods within a short period of time, which obviously results in obesity
   
3. Free Fatty Acids: Free fatty acids are claimed to cause insulin resistance, which is commonly seen in overweight people.
   

Second, consume ingredients suggested for losing weight:

1. Water: Drinking water will make some changes in metabolism and increase the amount of calories burnt off.
2. Green Tea: The catechins which are present in green tea are claimed to support the fat-burning process
   
3. Coffee: Caffeine and coffee are tested to result in 3-to-11-percent improvement in your metabolism and this helps speed up the fat-burning process by maximum 29 percent.
4. Fresh Fruits: They are rich in water and other essential nutrients are the best choices to lose weight fast. They will limit the amount of calories you take in the body and still make you feel full
5. Cayenne Pepper: Capsaicin in cayenne enhances the metabolism considerably and at the same time, makes you less eager to consume foods
