Looking for a proven diet to follow to lose about 40 pounds fast. While building muscle. Im 40 years old just starting a workout routing and weigh 270 pounds at 6' 3. I want to lose so I can begin with some gear. I know proteins such as tuna help burn but if anyone has a meal plan that has helped them please let me know. Thanks. Ive been reading the forums and they are helping but I want to start something now.
