Quick fix usually will result in water loss, which your body will try to replace in shortest time possible(within 2-3 days).
Depending on how much time you have, try making a very small breakfast, like 1/2 cup of oatmeal, easy on the brown sugar(add apple sauce)and an ounce of skim milk mozzarella or 2 tbsp cottage cheeze.
Take cut up vegetables-broccoli, calliflower, cucumbers, carrots,grape tomatoes,different peppers to work or school-no dip,try putting salt lightly over, have cubed ham and cheeze as well for protein.Have different fruit to snack through the day.
When you get home, before cooking supper have a snack of 2 walnuts of other nuts,celery with hummus or 1/2 cup of milk (can add banana and blend) If you are having a regular supper,use only bread plate and have mixed salad with 1/2 of hardboiled egg and very little olive oil and some lemon juice. No low fat dressings or bacon and croutons. Have some bread with salad-not commercial, even white homemade is better than Dempsters 12 grain. Italian and french are fine.
Different suppers-large salad filled with different veggies and greens,with egg, chunks of chicken,chickpeas, olives, croutons or bread.Cooked and mashed turnip, then put some fried bacon in it and bake for 15 min, pair with small chunk of beef or pork tenderloin or other meat.
Idea is to increase vitamin rich filler foods and decrease simple carbs. This example of diet makes you enjoy food and have energy without going hungry and tired.
You can also add fibres like psyllium or PGX to the above, but your gut will have more difficulty to adjust to it.If you feel hungry, try B100 complex,Vit C and Omega-3 supplements with food only.
Drink water, nothing with sweeteners, and I hope you like milk and cheeze.For desserts-have it very occasionally and share it with someone.Also, cup of homemade from scratch hot chocolate does the trick on the cold winter evening.
If you have time to walk everywhere, do it as well.
