He has been published extensively and currently holds a number of editorial roles for journals in his field. His research team is focused on understanding how the “gut talks to the brain” and how these signals can be optimized to improve people’s health. Therefore Adam wanted to take the opportunity to ask an expert on questions surrounding nutrition, burning fat and gaining muscle.

Question 1: Could you provide some general advice for what men and women should do to get started in losing weight and reaching their ideal weight goals?

Answer: Major research studies in the world such as Look AHEAD and DIOGENES show that using meal replacements for two meals a day is a very effective method of starting weight loss. The likely reason is because this approach is convenient, but also very controlled. 

Question 2: Is losing weight mostly about the diet & nutrition aspect or is it more about what exercises you carry out & how often?

Answer: A combination approach of diet plus exercise is more successful than any single approach on its own. In general, exercise is not that effective at initiating weight loss, but is a very effective method to maintain weight loss, especially if the exercise can be combined with long term nutritional approaches which increases protein intake as it enhances satiety. Exercise should also combine both aerobic and resistance training.

Question 3:  What is the best way to gain weight in muscle & not fat? Over a period of about 3 months?

Answer: Resistance training is the most effective method to gain muscle mass, however to optimise the muscle mass gain a significant increase in protein intake is required to allow the protein to be broken down to the building blocks of amino acids which in turn is then incorporated in the expanding muscle. Good hydration is also vital as it will allow enhanced recovery which in turn will enable to person to do more resistance exercise.
