1. Atkins Diet

• Essentially a low carbohydrate, high protein diet as well as the consumption of fats.
• Focuses on controlling insulin levels.
• This diet is targeted at those who wish to lose weight/drop body fat. Many bodybuilders use this diet when competitions are coming up in order to hit a low body fat percentage.

2. ‘Zone’ Diet

• This is a more all round diet. The ‘zone’ diet is broken into three; 30% fats, 30% protein and 40% carbohydrates.
• Much like the Atkins Diet, this diet also focuses on controlling insulin levels and thus aiding in the loss of weight/body fat.
• This diet encourages the consumption of unrefined carbohydrates, and fats, such as olive oil, avocados, and nuts.

3. Ketogenic Diet

• This is almost a half way mark between the zone diet and the atkins diet.
• Involves reducing carbohydrate intake and upping fat intake. This allows the body to burn fat as a fuel, rather than carbohydrates.
