The 21 days challenge started by Les Mills advocates eating a variety of meat, chicken and fish in your diet as a great source of protein. It is still a restricted dietary programme which will certainly help you shed a few pounds by following a controlled diet plan. It is a great tool to try out for a shorter period of 3 weeks especially if you are so much worried about your on-going weight gain.

Is this healthy?

Dr. Manoj Kutteri, Wellness Director at Atmantan Wellness Centre says, "In my personal opinion, the diet must be tailor-made for any person keeping in mind their health issues. However, it is certainly a good tool for the common man to help manage their weight coupled with endurance and strength training. Although recent studies do not reject fully the consumption of saturated fats from red meats, it has always been proven that a wholesome plant-based diet is far superior to an animal-based diet. Since health is a relative terminology, I do believe that a diet rich in whole grains, nuts and lentils, vegetables, fruits and superfoods can ensure similar weight loss on a slightly healthier way without going through the consequences of consuming red meats and other saturated fat especially among the India population who are genetically predisposed to cardiovascular diseases arising from the harmful variants of lipids."
