If you want to lose
Exercising without eating well can have various consequences, both short-term and long-term. Exercising without proper nutrition can hinder your performance, slow down recovery, lead to muscle loss, weaken your immune system, and make it challenging to manage your weight effectively.
It is not recommended to workout if you don't have food in your system, as the body needs energy from food to sustain physical activity. Exercise can be taxing on the body and without proper fuel, you may experience weakness, fatigue, and decreased performance.
Yes, you can lose weight by just doing exercise. Regular physical activity burns calories, which can help you create a calorie deficit and lead to weight loss. However, its important to note that exercise alone might not be as effective as when combined with a healthy diet.
Yes, you can still see results from workouts without following a strict diet, but your progress may be slower or inconsistent. Exercise alone can improve strength, endurance, and overall fitness, but nutrition plays a crucial role in muscle growth, fat loss, and energy levels.
Diet vs exercise for weight loss
According to Colleen Alrutz, health and fitness manager at Piedmont Newnan, diet wins 70% of the time when it comes to shedding pounds. To fast-track your weight-loss results, couple a healthy diet with regular physical activity. Exercise wins when it comes to keeping the weight off.
If you don't eat, you might feel slow-moving or lightheaded when you exercise. If you plan to exercise within an hour after breakfast, eat a light meal. Or have a sports drink. Focus on carbohydrates for the most energy.
Just 30 minutes every day can increase cardiovascular fitness, strengthen bones, reduce excess body fat, and boost muscle power and endurance. It can also reduce your risk of developing conditions such as heart disease, type 2 diabetes, osteoporosis and some cancers.
But scientific evidence shows that it's impossible to reduce fat in one specific area by exercising that body part alone. The body stores fat as triglycerides, which can be used for fuel anywhere in your body, not just in the exercised area.
When the calories you burn equal the calories you eat, you reach a plateau. To lose more weight, you need to either increase your physical activity or decrease the calories you eat. Using the same approach that worked at first may maintain your weight loss, but it won't lead to more weight loss.
You eat 30 grams of protein within 30 minutes of waking up, followed by 30 minutes of “steady-state cardiovascular exercise.” Eating a protein-filled breakfast in the morning can stave off cravings later, and exercising first thing ensures you get some movement before your day gets going.
Overall, the experts agree: Exercising in the morning is the best time of day to work out for logistical, effective and health reasons. When it comes to weight loss, a 2023 study published in the journal Obesity found exercising between 7 a.m. and 9 a.m. could help.
Think about your fitness goals. For example, if your goal is to boost your metabolism and start the day energized, morning workouts may be more suitable. If your aim is to improve performance and relax after a stressful day, evening workouts might be better. Consider your temperature preferences.
The final verdict? Exercising in a fasted state may burn some quick body fat, but it's not the best option for your body in the long-run. Eat a small snack or meal before and after your workout to ensure that you're properly fueled to perform your best in the gym and recover quickly when you get home.
“If all you do is walk briskly for 30 minutes, you've burned just 200 calories. Since 3,500 calories is a pound of fat, you'd need 17.5 days to lose one single pound. At most, you'd be losing two pounds a month.
We know from, you know, hundreds of randomized control trials that you can see changes in as small as two weeks in blood cholesterol to a healthy diet. We know it takes about six weeks to see improvements in blood pressure and about six weeks to see improvements in our insulin sensitivity.
Aerobic or cardio exercise
To burn off visceral fat, your first step is to include at least 30 minutes of aerobic exercise or cardio into your daily routine. Studies show that aerobic exercises for belly fat help reduce belly fat and liver fat.
The Science of Fat Loss
Think of it like a balloon losing air—it deflates, but doesn't disappear immediately. Over time, your body adjusts, but the jiggly feeling can be a temporary step along the way.
Yes—when it comes to building your glutes while walking, it's all about the incline. If you're on a treadmill, “anything above a five percent grade is going to target the glutes much more than a lower incline [or flat surface],” says Matty.
After a family trip made me realise how much my weight was holding me back, I started following a low-carb diet, weighing my food with a scale, and walking at least 10,000 steps a day. I've now lost 80 pounds (5 stone and 10lbs, or 36kg) in under 11 months. I have been overweight most of my life.
Ideally, include carbs such as a banana, low-fat yogurt, bowl of cereal, smoothie or a glass of milk. Avoid foods that are high in fat or fibre because they take longer to digest and may cause stomach discomfort during exercise.
Mayo Clinic suggests eating within 2 hours after exercise and to eat a snack if your next meal is further than 2 hours away. Bonci echoes similar advice: "Don't wait too long to refuel as that will delay repair and recovery."
Yes, eating less with a low-calorie diet puts you on the fast track to weight loss—and an intense exercise routine leads to increased metabolism and decreased body fat. In reality, a crash diet and overzealous exercise routine can be hard to maintain which may lead to more weight gain in the future.
