Whey Protein Burns Fat according to new study

13 01 2011

Whey protein stimulates fat burning better than other proteins.  Here is a study that was just released.  Our Protein at XCAP is called Whey Isolate and is the highest quality  whey available.  I am still working on my upcoming book about Fat Loss that will present the easiest and most effective way to lose body fat without the mental stress that diets cause.

Protein choices targeting thermogenesis and metabolism

Background: Dietary proteins stimulate thermogenesis and satiety more than does carbohydrate or fat; however, less is known about the differences between protein sources.

Objective: The objective was to determine the differential effects of 3 proteins on energy metabolism, satiety, and glucose control.

Design: Energy metabolism, satiety, and glucose control were measured in 23 lean, healthy subjects on separate occasions, before and 5.5 hours after consumption of 4 isocaloric test meals in a randomized, double-blind, crossover design. Three meals consisting of 50% protein (whey, casein, or soy), 40% carbohydrate, and 10% fat and a fourth meal consisting of 95.5% carbohydrate were compared with a glucose meal that provided the same glucose load as the protein meals.

Results: The thermic effect was greater after the whey (14.4 ± 0.5%) than after the casein (12.0 ± 0.6%; P = 0.002) and soy (11.6 ± 0.5%; P = 0.0001) meals and was greater after the whey, casein, and soy meals than after the high-carbohydrate meal (6.6 ± 0.5%; P < 0.0001).

Cumulative fat oxidation tended to be greater after the whey meal (16.2 ± 1.1 g) than after the soy meal (13.7 ± 1.0 g; P = 0.097) and was greater after the whey and soy meals than after the high-carbohydrate meal (10.9 ± 0.9 g; P < 0.05). The glycemic response to glucose was attenuated 32% by the proteins (P < 0.001) at the expense of a greater insulin response after whey than after glucose (154%; P = 0.02), casein (143%; P = 0.07), and soy (151%; P = 0.03). Subjective appetite sensations indicated that casein and soy were more satiating than whey (P < 0.01), but whey was more “liked” compared with casein and soy (P = 0.025 and P = 0.09, respectively).

Conclusion: The results suggest that different protein sources could be used to modulate metabolism and subsequently energy balance.

Hi John – I’m really looking forward to your new book. I like to mix the XCAP Protein with the XCAP 4Ever Greens and take it right after a workout. The stuff is great!
