O2 Diet reviewThe O2 Diet is an anti-aging, energy-boosting and weight loss diet from registered dietician Keri Glassman. In her book – “The O2 Diet: The Cutting Edge Antioxidant-Based Program That Will Make You Healthy, Thin, and Beautiful” – Glassman introduces readers to her 32-day plan, which centers on the ORAC (oxygen radical absorbance capacity) scale. The ORAC scale tells followers how rich a food is in antioxidants. The higher the foods score on the scale, the theory is the better these foods are for your health.

On the O2 Diet you don’t count calories, you count ORAC points. The idea is to eat more of the ORAC scale’s top-rated foods. Some of these include artichokes, leafy greens, salmon, blueberries, and a variety of herbs and spices. The lowest foods on the scale – which should come as no surprise – are soda, baked goods, candy and fried foods.

The plan is split up into difference phases. There is a 4-day cleanse and a 4-week plan that is split up into different phases. That said, it should be noted that the first few weeks of the plan are the toughest and can be quite intense.

Phase 1 lasts for 4 days and is the “cleanse” part of the diet. You’re allowed 50,000 ORAC points daily on few calories and are allowed to drink green tea and water.

Phase 2 lasts for 2 weeks. You get 30,000 ORAC points daily and can eat lots of fruits and vegetables and learn portion control.

Phase 3 lasts for 2 weeks and gives you more food options as well as allows you to add one indulgence per week.

Phase 4 is ongoing. Essentially, you maintain what you were doing in phase 3 and are allowed one more indulgence per week and one more high-ORAC fruit each day.

Although alcohol is not permitted during phases 1 and 2, you can drink it in moderation as one of your indulgences in the third and fourth phase.

On the plus side, the O2 Diet is a long-term diet plan that does promote healthy eating. It is possible to lose weight by following a calorie-controlled diet combined with exercise. Furthermore, Glassman includes helpful do-it-yourself options and preplanned menus in her book as well as a 6-step, fail-proof plan for ordering from restaurant menus. It also has several recipes and smart diet strategies that may help to give your metabolism a boost and help you manage your weight.

It should be noted that there is no proof that an ORAC rating has any relevance to human health. The ORAC scale was developed many years ago by the USDA (United States Department of Agriculture), to show how rich a food is in antioxidants. However, back in 2012, the USDA removed the table from their website because there were concerns that it had been misunderstood and was not being used as had been intended. The ORAC rating was only developed to serve as a scientific tool and not as a scale to dictate human health.

The O2 Diet may not be ideal for everyone to follow. It is restrictive when it comes to foods, especially in the first couple of weeks. This diet is also not likely to cause better weight loss results compared to other low-calorie diets for weight loss. That being said, if it is a diet that interests you, speak to your doctor first about your plans to try it. Make sure it is safe and sensible option for you.
