These principles work! And they have just been shown to help middle-aged type II diabetics (age 59±8 years) shed a quite impressive 6.7 kg of body fat (w/out exercise "only 5.7kg) in 12 weeks - without dieting as in not eating, although you're hungry (Otten. 2016).

- dried fruit - 130 g/day, not more,
- nuts - 60 g/day, so no snacking on almonds 24/7
- rapeseed or olive oil - maximum 15 g/day

- coffee & tea - max 300 ml/day (each, I assume)
- red wine - only one glass per week

What about compli-ance? Both groups increased their relative intake of protein and their intake of monounsatu-rated and polyunsatu-rated fatty acids. Both groups lowered their intake of carbohydrates and saturated fatty acids. The reduction of sodium intake was only significant in the PD-EX group. Nine of the 14 participants in the PD-EX group completed the 36 exercise sessions according to the study protocol. The remaining five participants completed between 27 and 35 workouts during the study period. The participants in the PD-EX group increased the cumulative weight load (weight × repetitions × sets) with the leg press during one exercise session from 1350 kg (900−1800) to 3000 kg (2700−4000) after 12 weeks.
What did the 1h workouts look like? The PD-EX group underwent a program comprising a combination of aerobic exercise and resistance training in 1-h sessions three times weekly at the Sports Medicine unit at Umeå University. The exercise sessions were performed on weekdays, with at least 1 day of rest between sessions. They were supervised by experienced personal trainers with bachelor’s degrees in Sports Medicine.All exercise sessions started with aerobic exercise. The first session of each week consisted of low-intensity aerobic training at 70% of the maximum heart rate on a crosstrainer (Monark Prime, XT 50, Vansbro, Sweden). The second session of the week consisted of ten high-intensity sprint intervals at 100% of the maximal workload on a cycle-ergometer (Monark, Ergomedic 839E, Vansbro, Sweden), with low-intensity cycling between the sprints. The third session of each week comprised six moderate-intensity 5-min intervals between 45 and 60% of maximal workload on a cycle-ergometer. The duration/workload of the intervals increased every other week. When necessary, the intensity of the aerobic exercise sessions was adjusted in accordance with the participant’s performance.
After the aerobic exercise, the sessions progressed to resistance training with both upper and lower body exercises, including leg presses, seated leg extensions, leg curls, hip raises, flat and incline bench presses, seated rows, dumbbell rows, lat pull-downs, shoulder raises, back extensions, burpees, sit-ups, step-ups, and wall ball shots. At each training session, the participant performed 3–5 of the aforementioned resistance exercises, with 10–15 repetitions and 2–4 sets. Once participants could complete all repetitions, the workload was increased for the following session. |

Is this the first paleo study? Even though, the number is still low, this is not the first one. In 2009, already, Jönssen et al. reported that "a 3-month study period, a paleolithic diet improved glycemic control and several cardiovascular risk factors compared to a diabetes diet in patients with type 2 diabetes" (Jönssen. 2009). In 2013, the same authors found that a "Paleolithic diet is more satiating per calorie than a diabetes diet in patients with type 2 dia-betes [and that t]he Paleolithic diet was seen as instrumental in weight loss, albeit it was difficult to adhere to" (Jönssen. 2013) - a result they had previously observed in patients with heart disease, too, when they compared a paleo to a Mediterranean diet (Jönssen. 2010), which also improve glucose tolerance less effectively than the paleo diet in said subject group (Lindeberg. 2007). Furthermore, studies in healthy individiuals Frassetto et al. (2015) like Österdahl et al. report that even "a short-term intervention showed some favourable effects by the diet" (Österdahl. 2008) such as weight loss, waist reductions and an improved quality of the diet and improved "BP [blood pressure] and glucose tolerance, decreases insulin secretion, increases insulin sensitivity and improves lipid profiles without weight loss" (Frassetto. 2015). In view of the fact that the less than a handful of long-term (>1 year), studies similar benefits when comparing paleo to other recommended diets, such as the Nordic Nutrition Recommendations in Mellbert et al. (2014) also show "greater beneficial effects" (e.g. fat mass, abdominal obesity and triglyceride levels just as they were observed by Ryberg, et al. in 2013) for the paleo diet(s), one could argue that the evidence in favor of paleo dieting in health and disease is slowly accumulating.
Eventually, diet is king, ... and that, just like the fact that doubling the energy deficit you have on paper won't double the loss of fat mass, shouldn't be news to you. That doesn't mean that dieting with exercise would not increase the loss of fat mass, but what is more important is that it helped the subjects - at least the male ones - maintain significantly more lean mass (=muscle and organ mass, which also affects you REE!).Whether the failure of the workout to produce significant lean mass maintenance in the women was due to their sex, their hormonal status (the females included in the study were postmenopausal) or the fact that they gravitated to eat less protein (this is speculative, since the study does not provides sex-specific intakes) cannot be said. Even in the men, the lean mass loss is yet large enough to speculate that we'd have seen sign. less muscle loss with higher protein intakes. After all, the 79g the subjects in the PED-EX group consumed on a daily basis amount to only 0,84g protein per kg of body weight. This has repeatedly been shown to be too little for older individuals - even if they were not dieting. A follow up to the study which includes (a) simply more protein or (b) an extra protein shake after the workouts that would bump the subjects' total protein intake into the ~1.6-2.0g/kg region would thus be something I'd like to see in the (not so distant) future.
As long as said study will not have been done, though (something tells me that it won't ;-), you can still reference Otten's study as evidence that you can effectively lose weight without cereals, dairy products, and legumes... I have to admit, though, that I suspect that especially the latter two of these "forbidden" foods would rather have augmented, not messed with the improvements in body composition Otten et al. observed in the study at hand | Comment!
