How Protein at Breakfast Can Help You Lose Weight

In the past, skipping breakfast has been associated with weight gain.

We now have good evidence showing that recommendations to eat or skip breakfast have no effect on weight gain or loss. You can read more about that in this article (1Trusted Source).

However, eating breakfast may be a good idea for other reasons. For example, it may improve mental performance in school children, teenagers and certain patient groups (2Trusted Source, 3Trusted Source).

This may also depend on the quality of the breakfast. Even if the stereotypical breakfast (like high-sugar breakfast cereal) has no effect on weight, a breakfast that is high in weight loss friendly protein may have different effects.

Summary

Recommendations to eat or skip breakfast often have no effect on weight. However, the same may not apply to a high-protein breakfast.

Protein is arguably the single most important nutrient for weight loss.

This is because the body uses more calories to metabolize protein, compared to fat or carbs. Protein also keeps you feeling fuller for longer (4Trusted Source, 5Trusted Source, 6Trusted Source, 7Trusted Source, 8Trusted Source).

One study in women showed that increasing protein intake from 15 to 30% of total calories helped them eat 441 fewer calories per day. They also lost 11 pounds (5 kg) in just 12 weeks (9Trusted Source).

Another study found that increasing protein to 25% of total calories reduced late-night snacking by half and obsessive thoughts about food by 60% (10Trusted Source).

In yet another study, two groups of women were put on weight loss diets for 10 weeks. The groups ate the same amount of calories, but different amounts of protein.

All the women in the study lost weight. However, the high-protein group lost about half a kg (1.1 lbs) more, and a larger percentage of body fat (11Trusted Source).

Protein may also help you maintain weight loss in the long term. A study found that increasing protein from 15 to 18% of calories made dieters regain 50% less weight (12Trusted Source, 13Trusted Source, 14Trusted Source).

Summary

Adding protein to your diet is a very effective way to lose weight. It may also help dieters sustain long-term weight loss.

Many studies are examining how protein at breakfast affects eating behavior.

Some of them have shown that high-protein breakfasts reduce hunger and help people eat up to 135 fewer calories later in the day (15Trusted Source, 16Trusted Source, 17Trusted Source).

In fact, MRI scans have shown that eating a protein-rich breakfast reduces the signals in the brain that control food motivation and reward-driven behavior (18Trusted Source).

Protein also helps you feel full. This is because it activates the body’s signals that curb appetite, which reduces cravings and overeating.

This is mostly due to a drop in the hunger hormone ghrelin and a rise in the fullness hormones peptide YY, GLP-1 and cholecystokinin (19Trusted Source, 20Trusted Source, 21Trusted Source).

Several studies have now demonstrated that eating a high-protein breakfast changes these hormones throughout the day (4Trusted Source, 16Trusted Source, 22Trusted Source, 23Trusted Source, 24Trusted Source, 25Trusted Source).

Summary

High-protein breakfasts reduce calorie intake later in the day. They improve the levels of your appetite-regulating hormones, leading to reduced hunger and cravings.

High-protein breakfasts can reduce appetite and cravings. They may also help you lose belly fat.

Dietary protein is inversely related to belly fat, meaning the more high-quality protein you eat, the less belly fat you have (26Trusted Source, 27Trusted Source).

One study of obese, Chinese teens showed that replacing a grain-based breakfast with an egg-based meal led to significantly more weight loss over 3 months.

The higher-protein breakfast group lost 3.9% of their body weight (about 2.4 kg or 5.3 lbs), while the lower-protein group lost only 0.2% (0.1 kg or 0.2 lbs) (23Trusted Source).

In another study, people on a weight loss program received either an egg breakfast or a bagel breakfast with the same amount of calories.

After 8 weeks, those eating the egg breakfast had a 61% higher reduction in BMI, 65% more weight loss and a 34% greater reduction in waist measurements (25Trusted Source).

Summary

Eating protein for breakfast can lead to significant weight loss, especially if you have a lot of weight to lose.

Speeding up your metabolism can help you lose weight, as it makes you burn more calories.

Your body uses much more calories to metabolize protein (20-30%) than carbs (5-10%) or fat (0-3%) (4Trusted Source).

This means you burn more calories by eating protein than by eating carbs or fat. In fact, a high protein intake has been shown to result in an extra 80 to 100 calories burned each day (8Trusted Source, 28Trusted Source, 29Trusted Source).

A high protein diet can also help prevent muscle loss during calorie restriction, and partly prevent the reduction in metabolism that often comes with weight loss, often referred to as “starvation mode” (11Trusted Source, 30, 31Trusted Source, 32Trusted Source, 33Trusted Source).

Summary

A high protein intake has been shown to boost metabolism by up to 100 calories per day. It can also help you maintain muscle mass and a high metabolism when you restrict calories.

In short, EGGS.

Eggs are incredibly nutritious and high in protein. Replacing a grain-based breakfast with eggs has been shown to help you eat fewer calories for the next 36 hours and lose more weight and body fat (4Trusted Source, 11Trusted Source, 15Trusted Source).

However, fish, seafood, meat, poultry and dairy products are also great sources of protein to include for breakfast.

For a complete list of high-protein foods, read this article.

Here are a few examples of high-protein breakfasts that can help you lose weight:

• Scrambled eggs: with veggies, fried in coconut oil or olive oil.
• An omelette: with cottage cheese and spinach (my personal favorite).
• Stir-fried tofu: with kale and dairy-free cheese.
• Greek yogurt: with wheat germ, seeds and berries.
• A shake: one scoop of whey protein, a banana, frozen berries and almond milk.

Protein pancakes are also a very popular breakfast food at the moment.

Summary

Eggs make a great, high-protein breakfast. However, other high-protein breakfast foods are also good choices.

If you do choose to eat breakfast, eat one that is rich in protein.

The protein content of the breakfast meals in the studies above ranged from 18 to 41% of calories, with at least 20 total grams of protein.
