You've got to get your diet & training in order...NOW.
As far as the diet, if you're doing a keto diet, you're going to have to stop eating a lot of things you're used to. No fruits. No grains/starches. No milk/dairy products. Starchy veggies like potatoes are gone, carrots, etc. are too.
Instead, you'll be eating meats, fish, fowl, eggs, cheeses, fats & oils, low carb vegetables, like lettuce, peppers, mushrooms, etc. and nuts (in small quantities). Instead of drinking pop or juice, you'll drink water, crystal light, iced tea, and other sugar-free drinks.
If you stick to this diet and dont cheat, you will lose TONS of weight just by changing your diet. The exercise will help your results even further.
Just think about it man... would you rather be eating some fine pussy or ice cream?
