A proper pre-workout meal will supply your body with everything you need for peak performance. When you exercise your body converts glycogen into glucose. This plays a crucial role in muscle contraction. By giving your body the right pre-training nutrition, you'll reduce muscle glycogen depletion.
What can happen if you don't eat before a workout?
When you exercise on an empty stomach, you may burn valuable energy sources and have less stamina. Low blood sugar levels may also leave you feeling lightheaded, nauseous, or shaky. Another possibility is that your body will adjust to continually using fat reserves for energy, and start to store more fat than usual.
What happens if you workout without eating before?
However, exercising on an empty stomach will also cause you to lose lean muscle mass at the same time, which can hinder long-term weight loss. Exercising without eating first can cause dramatic shifts in your blood sugar, and when it drops quickly you can feel nauseous, light-headed or dizzy.
Why is nutrition important before exercise?
The body can store carbohydrates in the muscles and liver as glycogen and use these stores as a source of fuel for physical activity. These glycogen stores are limited, so for those training at a high level, it is important to be fully fuelled at the start of any exercise.
Is it OK to workout on an empty stomach?
Working out on an empty stomach ensures enhanced fat burning because our body then relies on stored fat for energy since glycogen levels are depleted. This promotes fat loss over time. Further, 'fasted workouts' improve insulin sensitivity making it easier for the body to manage blood sugar levels.
Is it OK if I don't eat before a workout?
The type of activity you're doing can help determine whether you should eat before your workout. For light or low-impact exercises, such as walking, golfing, or gentle yoga, you may not need to fuel up beforehand. However, you should always eat before exercise that requires a lot of strength, energy, and endurance.
