When it comes to losing weight, the rules are always iffy. Some you can break, some you can bend, and others have to be followed perfectly. Here are five tips that you can’t go without if you want to shed pounds.

1. Eat breakfast. You don’t necessarily have to eat if you’re not hungry, but the odds are that your stomach will grumble sometime before noon. Make the first meal of the day hearty and nutritious.

2. Change your really bad food habits. Unfortunately, if you want to lose weight, you can’t continue to eat a pizza pie every single weekend. You don’t have to give up your favorite foods entirely, you just have to give up allowing yourself so much of them.

3. Don’t pig out on healthy foods. Sure, you’re “allowed” to eat almonds and avocados, but too much of anything still means you’re getting a ton of calories, regardless if they’re from healthy foods or not. Serving size is important no matter what you’re having a serving of.

4. Calories in have to be lower than calories out. This is simple math (and science) – if you’re not burning more than you’re eating, you will not lose weight.

5. Once you’ve dropped the weight, you can’t become the old you, habit-wise.

While you’re on the path to losing weight, you may not love the way your body looks. In the meantime, get a slimmer appearance with clothing like the kind the MeMoi brand makes.
