The reasons why you could eat 5000 calories and not gain weight are: You’re Not Accounting For All Measures Of Progress. You’re not Tracking Accurately. You’re Doing Too Much Activity. You Have A Substantial Amount of Muscle Mass. You’re Not Consistent Long Enough To See Progress. 1. 400 calories is not a lot when compared with the recommended daily caloric intake of 2500 calories per day for men, and 2000 calories per day for women. 400 calories would be 16% of the average man’s daily calories and 20% of the average women’s daily caloric intake, which is equivalent to a small and medium-sized snack. Is 2000 calories a day too much? 2,000-calorie diets are considered standard for most adults, as this number is considered adequate to meet most people’s energy and nutrient needs. Is burning 3000 calories a day a lot? But to benefit, the study suggests, we most likely have to exercise a lot – burning at least 3,000 calories a week. From USDA food consumption surveys of that era, the FDA knew that women typically reported consuming 1,600 to 2,200 calories a day, men 2,000 to 3,000, and children 1,800 to 2,500. 2000 is the min for average people. Teenagers have a faster metabolism so it'll actually be a little higher. And if you're weight training I'd do 3000 a day. If you tried to do anything without calories you're going to be fucking exhausted all the time while getting literally zero benefits for it. 2. Enter crankiness, which can easily be reversed by eating something. Tiredness and fatigue also go hand in hand with not eating enough, because you’re simply not providing the body with enough energy. These cues are often our body’s way of innately telling us what we really need. 3. I would think so, I'm starting to get stuck at the same weight at 5'10" eating 3,800 to 4,000 calories a day at 205 pounds. At 3,000 I would drop weight pretty rapidly. I’m 29 6ft 225. If you’re going to get another 45 pounds on your body you’ll need to eat at least another 1000 calories a day. Breakfast, snack, 1st lunch, 2nd lunch, pre-workout snack, post-workout snack, dinner, night snack (before sleep). It's much easier to eat 500 cal 9 times a day than it is eating 1500 cal 3 times a day. It sucks at first but you get used to it. 12. The_Roguish_Chef. tN6Tin.
