>>9533173Definitions of keto diets are inconsistent on how much carbs are allowed, but you don't need to try to do ketosis to lose weight, just go with a diabetic style diet. 30-45 grams of carbs per meal, no more. Count your calories, and try to pad your meals with fibrous vegetables like cabbage, broccoli, cauliflower, etc, they'll make you feel fuller on less calories. You really just have to think of your daily calories like a budget, and try to get as much bang for your buck each day. Carbs are high calorie items with little in the way of nutrition or fullness.
Also if you want to work in some exercise, look up some static hold exercise routines, planking, supermans, etc, and do pushups. It's all very low impact work with very good gains, even better if you're tall, since a lot of more active things like running put more stress on your joints.
