Lots of variables associated with Obeisity. Movement / Mobility is another contributor.  

I have essentially put aside Carbs. Sugar, bread, rice, carrots, orange juice, and potatos. My Beer and wine consumption is also minimized as they carry carbs. 

You have three source of fuels as consumption. Carbs, Fats, Alcohol.  

It is ususally recommended to take in one source of Feul. The worst thing you can do is consuming all 3. For example a deep dish Pizza with a pitcher of beer.  You will be consuming all 3 feuls at the same time.  Carb (Crust), Fat (Cheese), and Alcohol (beer).  

What the body does is it starts burning one feul at a time.  Alcohol has to be dealth with first, then it is carb (gluocose), and then it is Fat.  So one feul burns and the rest goes to the back burner. 

The Keto diet only takes in Fat as source of feul. And very effective in losing weight.   As long as you do not take in other source of feuls.  Especially carbs. Essentially bringing your body to a ketosis metabolic state. Alcohol if it is straight vodka or tequila it works. Wine and beer carry carbs. 

Here is a comparison of amount of carbs in beer vs Vodka
