Everyone has to do what works for them. Don't go on a diet!! Just make healthy lifestyle changes.
When you make a meal try to focus on veggies and fruit being your main dish and the meat, potatoes, and rice being your side dishes. Fill your plate with a lot of veggies and add a little of the things that make us fat.
In the morning try to eat things like yogurt and fresh fruit or oatmeal with raisins and apples with a slice of whole grain toast. Stay away from bagels..they are high in carbs. Fruit smoothies are a great way to get energy too. I just buy my favorite frozen fruit (a cherry blend) and then add things like bananas, fresh pineapple, granola, and things you like. My family loves my smoothies. Adding a little honey to make it taste better is great too.
Another good thing to do is make a pitcher of water and add some grapefruit slices,orange slices, and some fresh mint. Drink this all day long. (as much as you can) and it will help burn fat.
When exercising... don't do things you are going to hate or not look forward to. Don't make it something you feel you HAVE to do. Make it something you WANT to do. Put on your favorite music and dance or if you have an ipod or portable music device...walk around the block while listening to something up beat. When watching tv, or waiting for something to load on the computer do some squats or jumping jacks. Always remember that every little bit counts. Even if you do 10 squats it has made a difference.
Don't feel like you can't have an occasional sweat or treat. When you do just make it a small portion and eat it as slow as you can paying close attention to the textures and tastes. Make sure that you make it last long enough for your brain to kick in and acknowledge that you got a treat! LOL this may sound weird but the main thing that makes us fat is over eating. It takes our brains about 10 min to realize that we are full. If we rush through what we are eating we feel like we need more or were cheated out of having what we want.
Most important!!! Try not to stress about things. Stress makes us fat and makes us want to eat more. Find something that will help you to feel content in your life. Love, family, meditations, prayers, puppies. What ever makes you happy that is healthy for you.
