1. Your portions are off

You may be eating all the good stuff, but you’re eating too much of it. Take the time to read the serving size indications and stick to it by measuring out your portions or using an at-home food scale. Don’t trust yourself to guess what a cup of spaghetti looks like or you’ll be putting in all the effort of dieting without reaping any benefits. A study of overweight people found that 38 percent of those who practiced only portion control lost weight.

2. You give up too easily

It can be tempting to throw in the towel when you slip up. You may be thinking that if you’ve already ruined your diet you might as well stuff your face and start fresh tomorrow. This way of thinking will get you nowhere fast. It’s natural to overeat once in a while or indulge in that chocolate cake you know you should skip, but don’t let one mistake throw you off balance.

3. You’re exercising less

If you want to lose weight quickly and efficiently it is best to pair your diet with a regular exercise routine. Spend at least 30 minutes a day doing moderate-intensity activity at least five days a week. Whether that is a long morning walk, a bike ride, a yoga class, or an evening at the gym, make sure you don’t leave out the fitness component to your new healthy lifestyle.

4. You skip breakfast

You may think if you skip breakfast you can save those calories for lunch, snack, or dinner time, but by the time you get to lunchtime you’ll be starving and will have a tendency to overeat. Those “saved” morning calories won’t last long. According to the Mayo Clinic, eating a good breakfast helps keep you on track for healthy eating the rest of the day and refuels your body with energy to start the day.

5. You’re not getting enough protein

If you’re focusing on eating smaller portions and fewer snacks, but aren’t consuming enough protein you’ll constantly be hungry. Protein keeps your metabolism running, your energy up, and keeps you full longer as it is harder to digest than most carbohydrates. Include a lean protein in every meal and snack on items that are high in both fiber and protein like nuts, dried fruit, or hummus and veggies.

6. You’re drinking your calories

When you’re trying to lose weight you should be focused on drinking water. Not only does water make you feel full, but it is a pure, calorie free drink that is great for your skin and digestion. If you regularly consume a morning cappuccino, a soda with lunch, and a few beers with dinner you’re consuming a few extra hundred liquid calories a day.

7. You use food as a reward

Many people use food as a reward for completing a long day at work or completing a rigorous workout, but using food as a reward can be a dangerous pitfall when dieting. Emotional eating will sabotage your diet and leave you feeling worse off in the end. Studies show that 78 percent of American consumers are more likely to eat dessert as a treat to reward themselves. Rather than using food as a reward, give yourself an evening in with your favorite show or a new pair of running shoes.
