You've been dieting for a number of weeks, and everything is going fine. And you know you have a number of big dinners looming, but are nervous about losing progress. This article will outline how to avoid ruining fat loss progress when eating out, so you continue to lose body fat consistently.   

As inconvenient as it is, your body doesn't care that it's your best friend's birthday. It only knows that you're eating too much, or you're not.  

And it comes down to not only eating lower calories earlier in the day but the right protein sources. 

Your Lean Protein Options to Keep Fat at Bay.

Protein is a critical macronutrient to your health and weight loss goals. Here's why:

- Compared to the other macronutrients carbohydrates and fat, protein is better when it comes to keeping you full (1).

- Protein has only 4 calories per gram, as opposed to fat that packs 9 calories per gram (carbohydrates also has 4). (2).

- Because of the energy required by your body to breakdown and digest protein, you burn 30% of the calories upon eating it! For example, when you eat 100 calories from protein, you're only really eating about 70 calories (3). For fat, that percentage is only 0-3%, and just 5-10% for carbohydrates (3). 

Protein is your friend when it comes to staying full, and consuming fewer calories. So how does this fit into a real-world example?

Fighting Fat: What To Do Ahead of a Big Meal Eating Out

Let's say you have your friend's birthday party one evening at 6 pm. You know there will be plenty of beers, pies, cakes, donuts, and a vast array of calorie-dense finger food.

No problem.

lean protein sources

You'll want lean sources of protein to keep calories low ahead of 6 pm. Here are some of the best:

- Kangaroo

- Turkey

- Barramundi or canned tuna

- Whey protein powder

- Chicken breast

- Egg whites

- Beef jerky

These sources above contain high amounts of protein, with limited fat and carbohydrates. 

By consuming them with a source of fiber like spinach, lettuce, or other salads (minus any calorie-dense dressings!) you're effectively limiting your calorie intake ahead of your birthday party, thus reducing the urge to overeat and gain too much fat.

This is because fiber also helps you stay full (4-6).

A sample day might look like this:

Breakfast: Whey protein powder, black coffee.

Lunch: Chicken breast with 1 cup of spinach.

4 pm -- Two hours before the birthday party: one serving of beef jerky. 

Why won't any source of protein do?

Whilst you'll still feel full by consuming other sources of protein, the additional fat content means the strategy fails. This is because the calorie content will be too high.

Sources of protein that are NOT low in fat, that are to be avoided in this context, include:

- Pork Belly 

- Lamb

- Beef mince

- Ribeye steak

- Porterhouse steak

- T- Bone steak

- Fried chicken

Now we must stress, there is nothing wrong with the above protein sources. 

But in the context of keeping calories low on a day where a big meal is looming, they are not part of our strategy together here.

So once you've followed a sample day of lean protein sources similar to the above, you'll be able to indulge in whatever is on offer at your birthday party (or anywhere else), knowing that:

- You're not overly hungry and are not likely to overeat.

- Your calorie consumption for the day is as low as it can be without depriving yourself unnecessarily.

- You're free to indulge given you've been restrictive and disciplined in the lead-up.

We trust this strategy will be as effective for you as it is for us!

Remember, you can also do this if you decide you want to have a pizza or high-calorie meal just at home for dinner, and want a break to ensure any fat gain is minimal. 

Use it sparingly but do use it, and enjoy high-calorie foods without significantly hindering progress!
