Supplementing with Whey and Casein for Better Fat Loss
More than 10 well-controlled clinical trials have shown that increasing the ratio of lean protein foods in the diet results in better fat loss. Not only does this strategy enhance fat loss and preserve lean tissue, it also improves blood lipid profiles that protect against heart disease.
Getting Enough Protein with Supplementation
Many bodybuilders think they get enough protein in their diets, yet they complain of a lack of results from all their efforts in the gym. A golden rule is that when you’re not obtaining the results you desire from all those hours spent in the gym, increase your protein intake.
When it comes to building muscle and shed fat, some protein choices give you much best results than others. Whey Isolate is shown in clinical trials to provide better muscle gains and fat loss compared to other protein and carbohydrate control groups.
Also, many bodybuilders don’t know exactly how much protein or other macronutrients they need to consume each day to obtain the results they want. Not having accurate information on the amount of nutrients you need to consume every day, makes a difficult task like bodybuilding, an impossible one.
Better Health and Better Results with Casein
Often I’ve reported on the many health benefits of consuming a high quality supplement such as Whey Isolate. However, casein, (the other major dairy protein found in milk) is also shown to provide important benefits to people that exercise. Recent advances in dairy science technology have enabled researchers to identify a number of key peptides in casein that improve health.
Casein releases peptides (small chains of protein) into the system that help with digestion, metabolism, immune function and also help to regulate the hormones that control appetite and food intake.
Whey Proteins Suppress Fat Gain
A recent study compared the effects of casein and whey protein as the source of dietary protein on the activity of lipogenic enzymes in the liver and skeletal muscle of rats. Lipogenic enzymes serve to synthesize and accumulate fat. After two weeks of exercise, a significant decrease in the activity of liver lipogenic enzymes was observed in the rodents fed whey proteins.
The researchers concluded that whey protein may play an important role in suppressing liver fatty acid synthesis, thereby decreasing accumulation of body fat. Whey protein supplementation also improved the activity of muscle enzymes that help to burn fat for fuel during exercise.
These results need to be confirmed in humans but they do support other studies on rodents that show whey proteins enable better fat utilization in the hours after exercise.
An improved ability to burn fat and a decreased capacity to store fat are two more good reasons why Whey Isolate should be a staple of any bodybuilder’s diet.
