Pittsburg, Kansas | You might be surprised. Limiting calories will also do it. Our bodies have to be able to switch fuels when one source runs low. That is what our stored body fat is for. Any time we reach into our body fat for energy the liver can produce both ketones and glucose as required by the body.
The only way to burn body fat or consumed fat for that matter is with low insulin levels. Insulin is the key to the production of ketones. Insulin levels have to be low. That can be acomplished by lowering carbohydrate consumption or by limiting overall energy as calories. That is why some populations that rely mostly on carbs for their sustenence are able to stay lean and trim. They are likely to be calorie limited and not have an abundance of food they eat or drink ten times a day. They have periods between meals where insulin can go to low levels and tap into their body fat (stored groceries) for energy till the next meal.
Eating too often foods that raise insulin is every bit as bad as over eating as far as insulin levels are concerned. Unless the calories are limited enough so there is not excess energy making glucose.
Low carb is just an easier way (for me at least) to keep insulin levels low. As compared to low calorie low fat. Low calorie low fat can also work, but it will be against constant hunger and wanting to eat. Takes lots of willpower. I suppose it also takes willpower to avoid sugar and foods with excess fast carbs, but usually within a few weeks the cravings subside and it becomes easier. At least it did for me.
