There's a difference between low carb and very low/no carb diets. I am not advocating either but it is certainly true that processed carbs have little to recommend them nutritionally, play havoc with your blood sugar (and therefore appetite) and most of us, given free rein, eat far too large portions of them, often accompanied by high calorie sauces/lots of sugar etc. The reason low carb diets work is tied up with all that immediately being eliminated, together with the fact that protein keeps you feeling full for longer, so it is easier to eat less and stick to your resolutions.
Rather than going on a diet, which implies a short term fix, try cutting out just processed carbs as much as possible, maybe include a portion of healthier carbs at breakfast and lunch but have none at all, other than veg, with a source of lean protein, at dinnertime. Cereal is 90% of the time full of sugar, Porridge , wholegrain toast, eggs, yoghurt and fruit or fish (eg smoked salmon/kippers/sardines) make much better breakfasts.
Example of my day yesterday (not trying to lose weight but I exercise quite hard almost every day)
Breakfast - 2 poached eggs on buttered granary toast and tea with milk
Snack - skinny latte and an "eat natural" bar
Lunch - Bowl of spicy lentil soup with 1/2 roast chicken breast followed by a couple of squares of dark chocolate
Snack - 1/2 pot of spicy butternut squash dip with celery and peppers, 1/2 an avocado. Also stole a few of the kids oven chips and baked beans
Dinner - 3 large slices parma ham with steamed asparagus, butter and lemon followed by 2 pan fried sea bass fillets and a big pile of roasted veg (courgettes, peppers, red onion, tomatoes) then a bowl of greek style (full fat) bio yoghurt with raspberries, blueberries, sprinkling of hazlenuts and almonds and a drizzle of honey.
Usually we eat out once a week and most weeks get a takeaway one night, then I eat and drink whatever I fancy, rice and naan with an Indian, pasta, chips or whatever I feel like at a restaurant (tbh I rarely fancy pasta anymore but I do love chips ).
If I was trying to lose weight I would cut down the portions and be stricter with the "nights off". This to me is a healthy way of living that keeps my weight where I want it and most importantly, I feel great.
