A well-balanced, easily digestible meal eaten 60— minutes before a workout may improve performance, especially if you have not eaten for several hours In contrast, if your goal is fat loss, training with less food may help you burn fat, improve insulin sensitivity and provide other important long-term benefits 17 , Hydration is also closely linked to health and performance.

Many people tend to be dehydrated before working out, so it may be important to drink around 12—16 oz — ml of water and electrolytes before the workout 19 , 20 , Additionally, vitamins may affect workout performance, and may even reduce training benefits.

So although vitamins are important nutrients, it may be best not to take them close to your workout Nutrient timing may play an important role in pre-workout nutrition, especially if you want to maximize performance, improve body composition or have specific health goals.

Instead, what you eat for breakfast has become the hot topic. Many professionals now recommend a low-carb, high-fat breakfast, which is claimed to improve energy levels, mental function, fat burning and keep you full.

However, while this sounds great in theory, most of these observations are anecdotal and unsupported by research Additionally, some studies show that protein-based breakfasts have health benefits.

However, this is likely due to the many benefits of protein, and timing probably does not play a role Your breakfast choice should simply reflect your daily dietary preferences and goals.

There is no evidence to support one best approach for breakfast. Your breakfast should reflect your dietary preferences and goals. This reduction of carbs simply helps you reduce total daily calorie intake, creating a calorie deficit — the key factor in weight loss.

The timing is not important. In contrast to eliminating carbs at night, some research actually shows carbs can help with sleep and relaxation, although more research is needed on this This may hold some truth, as carbs release the neurotransmitter serotonin, which helps regulate your sleep cycle.

Cutting carbs at night is not a good tip for losing weight, especially since carbs may help promote sleep.

However, further research is needed on this. Instead, focus your efforts on consistency, daily calorie intake, food quality and sustainability.

Nutrition Evidence Based Does Nutrient Timing Matter? A Critical Look. By Rudy Mawer, MSc, CISSN — Updated on June 3, Nutrient timing involves eating foods at strategic times in order to achieve certain outcomes.

Here is everything you need to know about nutrient timing. A Brief History of Nutrient Timing. However, a closer look at the research shows that these findings are far from conclusive, and have two significant limitations 1 , 5 : Short-term blood markers: Many of the studies only measure short-term blood markers, which often fail to correlate with long-term benefits 6.

Ultra-endurance athletes: Many of the studies follow extreme endurance athletes, which do not necessarily represent the average person. Bottom Line: Nutrient timing has been around for several decades. The Anabolic Window: Fact or Fiction?

The theory is based on two key principles: Carb replenishment: After a workout, an immediate supply of carbs helps maximize glycogen stores, which can improve performance and recovery.

Protein intake: Working out breaks down protein, so post-workout protein helps repair and initiate growth by stimulating muscle protein synthesis MPS. Carb Replenishment One main aspect of the anabolic window is carb replenishment, since carbs are stored in the muscles and liver as glycogen.

Protein Intake The second aspect of the anabolic window is the use of protein to stimulate muscle protein synthesis MPS , which plays a key role in recovery and growth. Bottom Line: The anabolic window is a period of time after workouts that is said to be crucial for nutrient intake.

Carbohydrates, liquids and semi-solid foods leave the stomach relatively quickly and absorb more rapidly. Enzymes are proteins that speed up reactions in the body and are essential components to digestion as well as exercise metabolism.

Physical activity triggers a number of reactions in the body and activates enzymes such as glycogen phosphorylase and glycogen synthase, which are responsible for turning glucose blood sugar into glycogen stored carbohydrate.

These enzymes remain active in the muscles for 30 to 60 minutes following exercise, and fuel consumed within this window can restore glycogen twice as fast as a meal consumed two hours later. The aforementioned anabolic window is a result of heightened enzyme activity following a workout.

During this time frame, your body is more likely to turn your shake or food into carbohydrate both in the muscles and liver rather than fat.

Intense or long-duration exercise depletes muscle glycogen and breaks down muscle tissue protein. Therefore, the goal of post-exercise fueling is to replace muscle glycogen and begin regenerating muscle tissue. Adequate carbohydrate and protein feeding post-exercise helps restore glycogen and protein stores, respectively.

An important consideration, however, is how long it takes to utilize the energy we consume; carbohydrate can digest, absorb and subsequently raise blood glucose within 15 to 30 minutes.

Protein, on the other hand, digests more slowly and does not lead to peak amino acid levels in the blood for up to three hours.

Thus, consuming protein two to three hours before the end of your workout one to two hours prior, in most cases could result in more rapid tissue regeneration post-workout. But protein still plays an important role post-exercise, as it helps carbohydrate with its role.

The addition of protein to carbohydrate increases insulin production. Insulin is a hormone that facilitates the uptake and storage of carbohydrates and amino acids read more about hormones here.

Thus, you can restore glycogen more quickly and prepare for your next workout, when you consume a combination of carbohydrate and protein and for the record, a few grams of fat does not delay absorption significantly. A recent trend in fitness and athletics is a push for real food instead of pills, powders and bars.

Supplement manufacturers lead you to believe that liquid calories are superior to solid foods because they are absorbed more rapidly. And in a laboratory setting, this may be the case. But the only reason to use a supplement over a food is convenience.

Few of us have live-in chefs and all of us have busy schedules, so quite often carrying a bar or shaker bottle are the only viable options. When you do have the opportunity to prepare a meal, the extra digestion time compared to a shake will not hinder glycogen or protein resynthesis.

In fact lean meats, fruits, vegetables and whole grains have the benefit of more vitamins, minerals and antioxidants than the contents of your shaker bottle and may be considerably less expensive. Transportable food options such as chocolate milk, fruit, yogurt, trail mix, homemade energy bars and sandwiches may provide the best of both worlds.

As whole foods, they are nutrient dense and unprocessed, yet easy to take to the office or gym. High-water foods such as melons, apples, pears, cucumbers and bell peppers provide the benefit of assisting with re-hydration as well but you still need to drink water before, during, and after exercise.

A quick note regarding chocolate milk, which some tout as the best post-workout option. Low-fat chocolate milk has a great ratio of macronutrients, provides vitamins and minerals and is incredibly cost-effective.

However, most of the research involving chocolate milk is flawed as it has been compared to lower-calorie drinks and it is no more or less effective than a similar drink or food providing the same amount of calories, carbohydrates and protein.

Your goals are an incredibly important consideration when making pre-, during, and post-workout food choices. Two different people, for example—one with weight-loss aspirations, one with healthy weight gain ambitions—should have two different fueling plans.

For a weight-loss plan, total calories and carbohydrate should be less compared to a hypertrophy plan; protein, however, should remain relatively constant see below for more details. No one lives in a laboratory and almost no one measures every ounce of food or calculates carbohydrates and proteins down to the tenth of a gram.

For a pound individual with the goal of maintaining or gaining weight , these recommendations boil down to 90 grams of carbohydrate and 30 grams of protein a carbohydrate-to-protein ratio.
