Unlock Your Ultimate Weight Loss Potential: The Powerful Connection Between GLP-1 Agonists and Resistance Training!
**The Relationship between GLP-1 Agonist Therapy and Resistance Training**
Resistance training is perhaps the single **most** important activity to undertake while undergoing treatment with a GLP-1 agonist for weight loss.
First, what is a GLP-1 agonist, and what does it do to the human body? GLP-1 agonists, or glucagon-like peptide-1 agonists, such as semaglutide, primarily target the GLP-1 receptors found in various tissues, including pancreatic beta cells, the gastrointestinal tract, the brain, and potentially other locations. Activation of GLP-1 receptors leads to several physiological effects, such as:
1. **Pancreatic Beta Cells:** GLP-1 agonists stimulate insulin secretion from pancreatic beta cells in response to elevated blood sugar levels.
2. **Gastrointestinal Tract:** They slow down gastric emptying, reducing the rate at which food leaves the stomach. This helps control post-meal blood sugar spikes.
3. **Hypothalamus:** GLP-1 receptors in the brain’s hypothalamus contribute to increased feelings of fullness and reduced appetite, aiding in weight management.
4. **Liver:** GLP-1 agonists inhibit the liver’s production of glucose, helping to lower blood sugar levels.
By targeting these specific receptors in various tissues, GLP-1 agonists effectively contribute to improved glucose control, weight management, and overall metabolic health, making them valuable medications for individuals with type 2 diabetes or obesity.
GLP-1 agonists primarily work by:
1. **Increasing Insulin Release:** GLP-1 agonists stimulate the release of insulin from pancreatic beta cells in response to glucose, which helps lower blood sugar levels.
2. **Suppressing Glucagon:** They inhibit the release of glucagon, a hormone that raises blood sugar levels, leading to reduced glucose production by the liver.
3. **Slowing Gastric Emptying:** GLP-1 agonists slow down the rate at which the stomach empties its contents into the intestines, which helps control post-meal blood sugar spikes.
4. **Increasing Satiety:** They promote a feeling of fullness or satiety, which can lead to reduced food intake and aid in weight management.
5. **Potential Effects on Beta Cells:** Some GLP-1 agonists may also have positive effects on pancreatic beta cell function and survival.
Overall, these mechanisms contribute to improved glucose control, reduced appetite, and potential weight loss in individuals with type 2 diabetes.
Resistance training enters the conversation because with all of the above changes taking place in the body, it is quite easy for an individual to lose large quantities of muscle mass. Dr. James DiNicolantonio, a cardiovascular research scientist and author, emphasizes the importance of resistance training during weight loss efforts for several reasons:
1. **Preservation of Muscle Mass:** Resistance training helps preserve and even build muscle mass while losing weight. This is important because muscle tissue is metabolically active and burns more calories at rest than fat tissue. Preserving muscle mass can help prevent a decrease in metabolic rate during weight loss.
2. **Metabolic Health:** Engaging in resistance training can improve insulin sensitivity and glucose metabolism. This can contribute to better blood sugar control and reduced risk of type 2 diabetes.
3. **Enhanced Fat Loss:** Combining resistance training with a calorie deficit can lead to greater fat loss while sparing lean muscle tissue. This can result in a more favorable body composition and a healthier overall appearance.
4. **Afterburn Effect:** Intense resistance training sessions can lead to an “afterburn” effect, where the body continues to burn calories at an elevated rate even after the workout is completed. This can contribute to increased overall calorie expenditure.
5. **Bone Health:** Resistance training places stress on bones, promoting bone density and reducing the risk of osteoporosis.
6. **Psychological Benefits:** Regular exercise, including resistance training, can have positive effects on mood and mental well-being, which can be important during the challenges of weight loss.
7. **Long-Term Weight Maintenance:** Building muscle through resistance training can help with maintaining weight loss over the long term by keeping metabolism higher and making it easier to sustain the results achieved.
8. **Functional Fitness:** Resistance training improves strength, mobility, and overall physical function, enhancing one’s ability to perform daily activities and maintain an active lifestyle.
Dr. DiNicolantonio often highlights that resistance training should be part of a comprehensive weight loss strategy that includes a balanced diet and cardiovascular exercise. Consulting with a healthcare professional or fitness expert before starting any new exercise routine is recommended.
Quotes from Dr. DiNicolantonio:
– “Hard, physical effort replicates the environment we’re adapted for. It’s like putting our bodies in their natural state. What we call being fit is what our ancestors called being.”
– “If you don’t lift weights, you age faster. Sarcopenia/muscle loss occurs at 1 to 2% per year after age 30. This leads to an exponentially higher risk of injury and worse metabolic health with age. Eating a high-protein diet and resistance training are the best ways to fight against this.”
– “If you’re over 30 and you don’t have a huge belly, you’re in the top 10% of fitness. If you’re strength training also, you’re in the top 5%. Sprinkle in some cardio, and you’re in the top 1%.”
– “Working out consistently is hard. But being overweight is harder. Eating healthy meals 80 to 90% of the time is hard. Being chronically sick is harder. You can either choose something hard to give you health or live with something harder being sick.”
– “How to get in shape…the old way: eat low fat, eat low calorie, endless cardio. The new way: eat high protein, lift weights, walk.”
– “You have no energy to work out because you don’t work out. Once you start working out, your body will give you more energy. A body in motion stays in motion. Newton’s law applies to human physiology as well.”
– “Every workout session you skip is another day you get less fit. Keep showing up even on days you don’t want to. In three months, you’ll be unrecognizable. In 10 years, you’ll thank yourself. This is a long game. Stay fit for life.”
– “Who cares if you’re not the biggest, strongest, or leanest person at the gym? As long as you’re putting in the work, then you’re winning. It is you versus you every day. You are your greatest competition.”
– “Having a six-pack is cool. But being able to cut your own grass or lift your own groceries when you’re older is cooler. Fitness is a long game. Stay fit for life.”
– “Work out in the morning. That way, if life gets too busy or you’re too tired after work, you’ve already put in the work. Prioritize your health. This is the way.”
– “Here’s your bulletproof plan to lose fat and gain muscle simultaneously. Number one: lift weights 3 to 5 times per week. Number two: walk daily for 30 to 60 minutes. Number three: eat 30 to 50 g of protein per meal. Number four: do cardio three times a week. Three months
of this, and you’ll be unrecognizable.”
– “Weight lifting has a direct impact on your mental health. Building muscle helps strengthen the mind and relieve stress. Get into your body to get out of your mind. Lifting is the best stress reliever.”
If the thought of going to the gym makes you cringe, give us a call. I had a client tell me the other day, ‘This place is exercise for people who hate exercise. It’s a gym for people who hate the gym.’ We have programs at both Mobile and Fairhope that can help you lose fat and build muscle in a fraction of the time it would take working out in a normal gym setting. We harness cutting-edge technology and data to get this done in a smart, healthy, and sustainable way.
