Weight training and bodybuilding nutrition are sciences like anything else. There's biology and biochemistry and physiology, with rules and a base of evidence. Selling supplements, most of which are not needed, has become such a huge business in the commercial weight training and bodybuilding industry that it is almost impossible to know if you are getting an objective evaluation of a bodybuilding diet.
You need to eat sufficient food and carbohydrate to sustain your activities. Too little carbohydrate, and your body will break down your muscle for glucose and reverse all those hard-gotten gains. Don’t believe advice that says carbohydrates are fattening. Instead, modify your carbohydrate intake for the better by avoiding refined flours, sugars, sweets and other quickly absorbed or processed carbohydrates when you are not exercising intensely.
Contrary to certain rumors that animal-based protein is more suitable to trigger muscle growth than plant-based protein, a study by Mangano et al. (2017) could not provide any evidence for this. In contrast, if combined properly, plant-based protein can even have a higher biological quality. A combination of one part wheat protein (e.g. seitan) and two parts soy protein (e.g. tofu) has thus been favored by many bodybuilders. Some bodybuilders, such as Patrik Baboumian and Robert Cheeke, follow a strict vegan diet.[37]
You’ll begin the program with a full-body training split, meaning you’ll train all major bodyparts in each workout (as opposed to “splitting up” your training). Train three days this first week, performing just one exercise per bodypart in each session. It’s important that you have a day of rest between each workout to allow your body to recover; this makes training Monday, Wednesday and Friday—with Saturday and Sunday being rest days—a good approach.

This is very important and can be very beneficial for beginners. It allows you to track your progress, see what exercises you enjoy, which ones you are improving the most, and what areas you need the most work on. Your journal should include the date, time of workout, duration of workout, the exercises, sets, reps, rest between sets, meals for the day, and supplements you may be taking.


Perform three weight-training sessions per week, hitting your whole body each time. Base your routine on compound exercises such as squats, lunges and deadlifts. These burn the most calories, hit more muscles and give the best bang for your buck, claims Rachel Cosgrove, strength coach and co-founder of Results Fitness in California. If you're not sure of any exercise techniques, ask a trainer at your gym for assistance.
