For a start, cut the sugar. Especially from sugary drinks: a non-diet soda can has ~40g of sugar (10 teaspoons), which is really awful. There's a reason for why there's no sugar daily recommended value, and is because that value is 0. Then, make sure to consume enough soluble and insoluble dietary fiber. To stay healthy you need not only to assimilate nutrients, but also your body needs to get rid of byproducts. Fiber facilitates that process. Then, instead of eating less, you can also replace ingredients and eat more frequently. There's an energy cost to eating, and eating more frequently makes you spend more energy. By replacing ingredients I mean cutting butter and cheese and replace it with tofu, full eggs by egg whites, for instance. Then, drink water with your meals. Filling yourself with water can help you trick your brain into believing you are full. Then, there's the bacteria in your gut and that affects what is going on when you eat. I think it's a very important aspect that needs to be considered but I have no idea how to take action around this specific part. Probiotics might help. Finally, starving yourself not necessarily works. Some people might end their diet and go back to overeating. Then, starving yourself might have negative side effects.
