False. Fad diets aren't healthy not only will they damage one's mentality, it's not the proper path to go to stay healthy. Supplements won't assist you at all, its best to get nutrients like your vitamins and minerals from real food rather than that.
Perhaps the use of fad diets, fasting and supplements will help you maintain a certain weight but it will surely not be healthy at all.
The best way to maintain a healthy weight is to have a diet that includes all types of food, respecting the food pyramid that determines the proportion of each food and also must incorporate the corresponding physical activity according to the food we eat. It is always recommended to go to a nutritionist, who can determine a specific diet according to their physical context, activity and metabolism.
There is 2 sides to doing a full body workout in the morning. One would be that it would be the best because it would wake you and ur body up and make you ready for your day and feel more energetic and more accomplished. However the other side is no because it does have the risk of you possibly of you getting a injury because you might do the workout before having something to eat which might make you feel sick and could have the possibility of you tear or pulling a ligament if you don't stretch.
